Frequently asked questions.

An enzyme is a biological catalyst that speeds up chemical reactions — in the body, and in industrial processes such as food processing, textile finishing and detergents — without being consumed itself.

Enzymes help break down food and substrates, while probiotics are live beneficial bacteria that support a healthy gut. Many of our custom blends combine both.

Feed enzymes are proteins added to animal diets to break down specific feed components that animals digest poorly on their own. Common examples are phytase for phytate, xylanase and β-glucanase for fibre, and protease for protein. They help animals use more of the energy, amino acids and minerals already present in the feed.

Phytase is the most widely used feed enzyme. Plant ingredients store much of their phosphorus as phytate, which pigs and poultry cannot fully digest. Phytase releases that phosphorus, so less inorganic phosphate needs to be added and less phosphorus is excreted.

Feed enzymes are not medicines, but better digestion may support gut health. Less undigested material reaches the hindgut, and enzymes such as xylanase can lower digesta viscosity in wheat- and barley-based poultry diets, which is linked to drier litter. Health outcomes still depend on management, hygiene and the whole diet.

It depends on the enzyme and the conditioning temperature. Some enzymes lose activity at high pelleting temperatures, so feed mills either choose heat-stable products or spray liquid enzymes onto the pellets after cooling. Ask the supplier for heat-stability data and check recovery in the finished feed.

There is no single dose. It depends on the enzyme's activity, the ingredients in the diet, the species and the nutrient values the nutritionist wants to apply. Start from the supplier's technical data sheet, use a dosage calculator for planning and confirm the result in a feeding trial.

Cellulase breaks down cellulose, the main structural fibre in plant cell walls. In feed, its chief benefit is opening those walls so that starch, protein and other nutrients trapped inside become easier for the animal to digest. It is usually combined with other fibre-degrading enzymes.

Only to a limited extent. Pigs and poultry do not produce cellulase themselves; some fibre is fermented by microbes in the hindgut, which is more developed in pigs than in poultry. Added cellulase helps break down fibre earlier in the digestive tract, where the released nutrients can be absorbed.

Rumen microbes already produce cellulases, so responses to added enzymes vary with the forage, the enzyme product and the feeding system. Fibrolytic enzymes are studied for improving forage digestion and for treating forages before feeding, but results should be confirmed on farm.

The two differ mainly in the pH range where they are most active. Acid cellulases work best in mildly acidic conditions, while neutral cellulases are more active closer to neutral pH. Choose the type whose activity profile matches where the enzyme needs to work, and check the pH curve in the technical data sheet.

Xylanase, β-glucanase and mannanase are common partners, because plant cell walls contain hemicelluloses as well as cellulose. Phytase and protease are often added to the same diet for their separate benefits. A combined product or custom blend can be matched to the main ingredients in the formula.

Phytase is an enzyme that removes phosphate groups from phytate, the form in which most phosphorus is stored in cereals, brans and oilseed meals. Pigs and poultry produce little phytase of their own, so much of this phosphorus would otherwise pass through undigested. Added phytase makes it available for absorption, which reduces the need for inorganic phosphate supplements.

Ruminants such as cattle and sheep have rumen microbes that produce phytase and break down phytate before it reaches the small intestine. Pigs and poultry are monogastric animals with limited phytase activity of their own. That is why phytase is a standard feed enzyme for pig and poultry diets.

FTU is the activity unit most often used for feed phytase. It is generally defined as the amount of enzyme that releases 1 micromole of inorganic phosphate per minute from sodium phytate under stated pH and temperature conditions. Methods and conditions differ between suppliers, so FTU values from different products are not always directly comparable.

Steam conditioning and pelleting expose feed to heat and moisture, which can inactivate unprotected enzymes. Thermostable phytase variants, coated or granulated products and liquid phytase sprayed onto pellets after cooling are the main ways to protect activity. Ask suppliers for recovery data at conditions similar to your mill's, and test finished feed.

The dose depends on the species, age, diet composition, calcium and phosphorus levels, the product's activity and the amount of phosphorus you want to release. It is set from the supplier's trial data and confirmed by your own trials. Our enzyme dosage calculator converts a target in units per kg of feed into grams of product per tonne.

When phytase releases phosphorus already present in the feed, less inorganic phosphate needs to be added and less phosphorus is excreted in manure. Lower manure phosphorus reduces the risk of nutrient run-off into rivers and lakes. It also reduces reliance on mined phosphate, which is a finite resource.

Alpha-galactosidase is the enzyme most closely linked to beans and pulses. It breaks down raffinose and stachyose, sugars that humans cannot digest on their own and that gut microbes otherwise ferment. It is used in formulations that may support comfortable digestion of bean-rich meals.

Lactase splits lactose into glucose and galactose. It is used both to make lactose-free or reduced-lactose dairy products and in supplements taken with dairy foods by people who have difficulty digesting lactose.

Pineapple and papaya contain the proteases bromelain and papain, but the amount varies with ripeness, variety and processing, and heat during cooking or pasteurisation inactivates them. Formulated enzyme ingredients are standardised to a declared activity, which makes their performance more predictable.

It depends on the enzyme. Many fungal and microbial enzymes remain active over a broader pH range, while pancreatic enzymes such as pancreatic lipase are sensitive to acid and are often protected with an enteric coating. Formulators choose the source and dosage form with this in mind.

Yes. Enzymes act directly on food components, while probiotics are live microorganisms, so the two are often combined in gut-health formulations. Compatibility, moisture control and shelf-life testing are important when they share one product.

The core enzyme is a coagulant such as rennet (mainly chymosin), which sets the milk into curd. Lipases and proteases are used for flavour development and ripening in some cheese types, and phospholipase may be used to improve fat retention in certain cheeses.

Microbial coagulants and fermentation-produced chymosin are not taken from animal stomachs, so they are widely used in cheese sold as suitable for vegetarians. Whether a product can carry a vegetarian, Halal or Kosher claim depends on the full supply chain and its certification, so check the documents for each lot.

Transglutaminase links milk proteins to each other, which builds a firmer gel. In set and stirred yoghurt it is used to improve body and reduce whey separation. The right level depends on the milk base and the texture target, so it should be set through trials.

It depends on the market and on how the enzyme is used. Many regulations treat enzymes that have no function in the finished food as processing aids, but the rules differ by country. Check the requirements of FSSAI or the relevant authority for each market you sell into.

Dose depends on enzyme activity, milk composition, temperature, pH and holding time. Start from the supplier's TDS, run small trials at your own conditions and confirm at plant scale. Our enzyme dosage calculator can help you plan the first trial range.

A processing aid is used during manufacture for a technical purpose and has no function in the finished food, for example an enzyme inactivated by baking. A food additive keeps a function in the final product. How a given enzyme use is classified depends on local regulation, so check the rules for each market.

Most food enzymes are proteins that lose activity when heated above their stable range, so baking, pasteurisation, blanching or a dedicated heat step usually stops them. Some heat-stable enzymes need a stronger step or a pH change. Check residual activity if the product is not heated.

Raw materials, water, pH, temperature profile and holding time all differ between plants, and enzymes respond to each of them. Activity units also differ between suppliers. That is why a supplier's dose is only a starting point and local trials are needed.

Keep them sealed in a cool, dry place away from direct sunlight, and follow the storage conditions on the TDS. Activity slowly declines over time, and faster in heat and humidity. Use stock in rotation and recheck activity on older lots before critical batches.

Food-grade enzymes are made to purity specifications for use in food, but enzyme dust can cause respiratory sensitisation in workers who inhale it. Use dust control, avoid dry sweeping and provide suitable masks and gloves. Liquid or granulated forms reduce dust exposure.

Pectinases are the main enzymes. They are added to the fruit mash to release more juice and to the raw juice to break down pectin before clarification. Cellulases and hemicellulases are sometimes combined with pectinase for fruits with tough cell walls.

Beta-glucans from barley cell walls make wort and beer viscous, which slows lautering and filtration. Beta-glucanase breaks these chains down and lowers viscosity. This is especially useful with under-modified malt or with unmalted barley and other adjuncts.

They can help. Amylases convert the starch in oat or rice bases into sweeter sugars, and lactase turns lactose into sweeter glucose and galactose. Less added sugar may then be needed for the same taste, but the sugars formed still count towards total sugars on the label.

Usually not in the same way as clear juice. Full depectinisation would make the cloud settle out. Cloudy juices may still use a mash enzyme for yield, but the enzyme type and dose are chosen to keep a stable cloud.

In most cases no. Pasteurisation or other heat treatment inactivates them before packing. If a drink is not heat-treated, or the enzyme is heat-stable, check residual activity to avoid changes during storage.

Digestive enzymes help break specific food components into smaller units the body can absorb. Lactase helps break down lactose, alpha-galactosidase acts on the complex sugars in beans, and protease, lipase and amylase act on protein, fat and starch. Products containing them may support comfortable digestion of the foods they target.

Some bloating comes from gut microbes fermenting food components that were not digested earlier, such as lactose or bean sugars. Enzymes that break those components down may reduce the fermentable residue. Responses differ between people, and persistent symptoms should be assessed by a doctor.

No. Over-the-counter digestive enzyme products should not claim to cure, treat or prevent any disease. Prescription pancreatic enzyme therapy for exocrine pancreatic insufficiency is a regulated medicine used under medical supervision, which is a separate category.

Digestive enzymes act on food that is present in the gut, so products are normally designed to be taken with or just before a meal. The exact directions depend on the product format and should be set by the brand based on its formulation and local regulations.

Activity should be declared in units for each enzyme, such as ALU for lactase or FIP units for lipase, with the assay method stated. Weight alone does not show how much enzyme activity a product delivers.

Most malt is made from barley, but wheat, rye, oats, sorghum and millets such as finger millet (ragi) are also malted. The grain is soaked, allowed to sprout under controlled conditions and then dried in a kiln.

Diastatic malt still contains active starch-degrading enzymes, mainly amylases, so it can convert starch into sugars in a dough or mash. Non-diastatic malt has been heated enough to inactivate those enzymes and is used for colour, flavour and sweetness.

Malt supplies the starch that becomes fermentable sugar and the enzymes that make that conversion happen during mashing. It also contributes colour, flavour, body and nutrients for yeast. The choice of malt types shapes the style of the beer.

In many bread formulations it can. Fungal amylase gives standardised activity and is inactivated earlier in baking, which lowers the risk of a sticky crumb. Some bakers still use malt for its flavour and colour, sometimes together with enzymes.

Malt extract is made by mashing malt in water so its enzymes convert the starch to sugars, then concentrating the liquid into a syrup or drying it to a powder. It is used in bakery, malted drinks, breakfast cereals and brewing, and it can be diastatic or non-diastatic.

The main difference is the source. Papain is extracted from the latex of unripe papaya fruit, while bromelain is extracted mainly from pineapple stem. Both are cysteine proteases that break proteins into peptides, but they differ in activity profile, heat tolerance, the units used to declare them and their typical applications.

Not one-for-one. They are declared in different units (usually TU for papain and GDU for bromelain), they behave differently with heat and pH, and a label may name a specific source. If you want to switch, run a side-by-side trial in your own product and check regulatory and labelling requirements.

Papain is commonly expressed in tyrosine units (TU), often per milligram, based on peptides released from casein. Bromelain is usually expressed in gelatin digesting units (GDU) per gram, based on amino nitrogen released from gelatin at pH 4.5 and 45 °C. Some suppliers also use milk-clotting units, and pharmacopoeial grades use the method in their monograph.

Papain is generally regarded as the more heat-tolerant of the two and can keep working during the early stages of heating. Bromelain tends to lose activity at lower temperatures. Exact behaviour depends on the preparation, the food matrix and the time at temperature, so test under your own process conditions.

Fresh pineapple contains bromelain and fresh papaya contains papain. Both proteases break down gelatin, which is a protein, so the gel cannot form. Canned or cooked fruit works because heating has inactivated the enzymes.

Yes. Both are used in digestive enzyme formulations intended to support protein digestion, and bromelain is also sold as a single-ingredient supplement. Any health claim must follow the rules of the market where the product is sold, and claims should be supported by evidence for the specific ingredient.

Enzymatic cleaners contain enzymes that break specific organic soils into smaller molecules. Proteases break down proteins, amylases break down starch and lipases break down fats. The smaller fragments dissolve or disperse more easily and are removed by surfactants and rinsing.

Yes. Enzymes work by catalysing reactions, which takes time, so a short contact period before wiping or rinsing usually improves results. The ideal dwell time depends on the soil, temperature and enzyme level, and should be stated in the product's directions for use.

Generally no. Chlorine bleach and strong oxidants denature enzymes and destroy their activity. If both disinfection and enzymatic cleaning are needed, they are usually carried out as separate steps or supplied as separate products.

Many odours come from organic residues such as food, urine or body soils that bacteria break down into smelly compounds. Enzymes break those residues down so they can be removed, which addresses the source rather than masking the smell. Some drain and odour products also contain Bacillus spores that produce enzymes in place.

Finished enzymatic cleaners are widely used in homes and workplaces. Concentrated enzymes, however, are proteins that can cause respiratory sensitisation if inhaled as dust or aerosol, so manufacturers should handle raw enzymes with appropriate controls and avoid formulations that create fine sprays of concentrated enzyme.

Enzymes break down specific stains into smaller fragments that the detergent can wash away. Protease targets protein stains, amylase targets starch, lipase targets fats and oils, and mannanase targets gum-based stains. Cellulase is used mainly for fabric care, helping to keep cotton smooth and colours bright.

Enzymes are one of the main reasons modern detergents perform well at lower temperatures. They break down stains that surfactants alone struggle to remove without heat. Performance still depends on the enzyme type, wash time and formulation, so detergents should be tested at the temperatures consumers actually use.

Enzymes are biodegradable proteins, and they allow effective washing at lower temperatures, which reduces energy for heating water. They can also help formulators reduce some other ingredients. The overall footprint still depends on the full formulation, packaging and use, so claims should be backed by evidence.

Cellulase acts on the small fibre ends that appear on cotton garments with wear. Removing them reduces fuzz and pilling, helps colours look brighter and can reduce greying caused by soil trapped in the fibres. It is a fabric-care enzyme rather than a stain remover.

Oxygen bleach such as sodium percarbonate is used in many enzyme powders, but the enzymes are protected as coated granules and kept in separate particles. Chlorine bleach destroys enzyme activity. In liquids, combining enzymes with bleach is much harder and usually avoided.

Clinical data means results from studies in people, ideally well-designed controlled trials in a population similar to your customers. Laboratory and animal studies help explain a mechanism, but regulators generally expect human evidence before a health-related benefit is promoted.

Only with care. Effects of probiotics are generally considered strain-specific, so a study on one strain does not automatically support another strain of the same species. The strain designation, daily amount and format in the study should match your product as closely as possible.

It is a dossier that lists each claim you make and the evidence that supports it, such as study summaries, CoAs, stability reports and regulatory notes. It should be dated, version-controlled and reviewed whenever the formula, supplier or claim wording changes.

Factual composition and quality claims, such as the named strain, the declared count at the end of shelf life, or vegetarian and certification status, can usually be supported by specifications, CoAs and stability data. Any wording about a health or body-function benefit needs a stronger evidence base and local regulatory review.

We supply samples, technical data sheets and certificates of analysis on request, produced in our GMP, FDA-registered facility with in-house QC labs. These documents support composition and quality claims; brands remain responsible for health claim review in their own markets.

Early involvement lets R&D flag what the product can and cannot do before messaging is built around it. It also gives marketing time to request the data a claim will need, rather than discovering gaps just before launch.

A claim log is a shared, version-controlled list of every product claim, its approved wording, the supporting evidence and the person who approved it. Both teams use it as the single source of truth for packs, websites and sales material.

Work in three steps: state the lab finding, explain what it means in plain words, then write the claim and check it against the original data. If the plain-language version says more than the data shows, rewrite it or request more evidence.

At minimum, R&D confirms the science, QA confirms the product matches the specification, and a regulatory or compliance reviewer checks the wording for each market. Marketing owns the final copy but should not approve claims alone.

Useful supplier documents include technical data sheets, certificates of analysis, specifications and certification copies. Enzyme Bioscience provides samples, TDS and CoA on request to support customers' product development.

Informed shoppers look for named strains rather than just species, the count guaranteed at the end of shelf life, clear dosage directions and storage instructions. Honest, specific labels also make it easier for retailers and pharmacists to recommend a product.

Convenience-led shoppers tend to prefer once-daily capsules, single-serve sachets, gummies and functional foods or drinks that fit an existing routine. The format must be matched to the ingredient, because some probiotic strains and enzymes are more sensitive to heat, moisture and processing than others.

Use cautious, evidence-matched wording such as "may support digestive comfort" and avoid words like cure, treat or prevent. Check every claim against the evidence for the exact strain and amount used, and against the rules in each market where the product is sold.

Yes. Digestive enzymes such as lactase and alpha-galactosidase are used in formulations for people who find certain foods hard to digest, and they can be combined with probiotics in multi-ingredient products. Compatibility and stability should be tested in the final format.

Yes. Through our ENZYVIVE® custom-blend service we develop enzyme and probiotic blends to a customer's brief, and we supply samples, TDS and CoA on request. Packaging options include 25 and 50 kg HDPE drums and retail pouches.

Price per kg ignores how much active material survives processing and storage. An ingredient that loses activity quickly needs a larger overage or a shorter shelf life, so its real cost per effective dose can be higher than a more stable but more expensive alternative.

The main stressors are heat, moisture, oxygen and light, plus interactions with other ingredients such as acids or minerals. Enzymes can lose activity when their protein structure unfolds, and vegetative probiotic cells lose viability when exposed to heat, moisture or oxygen.

An overage is extra active ingredient added at manufacture to compensate for expected losses, so the product still meets its label claim at expiry. It should be calculated from real stability data in the final formula and pack, and reviewed when the formula, supplier or packaging changes.

Ask for real-time data at the intended storage conditions, any accelerated data, the assay method used, the packaging tested and the activity or count remaining at the proposed shelf life. Then confirm the results in your own formula, because supplier data on the raw ingredient may not reflect your matrix.

Spore-forming strains such as Bacillus coagulans are generally more tolerant of heat and moisture than many vegetative lactic acid bacteria, which is why they are often chosen for shelf-stable formats. Their stability should still be confirmed in the specific product and pack.

Most products combine a micronutrient base, such as vitamins C and D, zinc and selenium, with newer ingredients. These include strain-specific probiotics, postbiotics, beta-glucans from yeast or mushrooms, traditional botanicals such as ashwagandha or tulsi, and microalgae such as spirulina and chlorella.

This depends on the market. In the EU, nutrients including vitamins A, C, D, B6 and B12, folate, zinc, selenium, copper and iron are authorised to state that they contribute to the normal function of the immune system. Claims for probiotics and botanicals are more restricted. Claims to prevent or treat infections are not allowed for foods and supplements.

A large share of the body's immune cells is found in tissue associated with the gut, which is why probiotics are studied for immune-related end-points. Results are strain-specific and evidence varies. Wording such as 'may support immune health' should be used only where it is substantiated and permitted.

Beta-glucans are polysaccharides found in the cell walls of yeast, fungi such as mushrooms, and cereals such as oats and barley. Their structure differs by source, and so do their uses: yeast and mushroom beta-glucans are studied for immune support, while oat and barley beta-glucans are best known for cholesterol-related claims.

Enzymes are not immune actives themselves. They are used as a digestive component in combination formulas and in manufacturing, for example to help extract compounds from plant material or to produce yeast-derived ingredients. Their claims should stay within those roles.

It is a way of presenting verified technical facts as a clear narrative: the customer's problem, how the ingredient works, what evidence supports it and what changes as a result. The story adds structure and relevance, not new claims.

Ordinary copy often leads with adjectives such as advanced or powerful. Science-backed storytelling leads with a real problem and a mechanism, and every statement can be traced to data, a specification or a published source.

Yes. Formulators, QA teams and buyers are people who remember a clear explanation better than a list of numbers. Application notes, process diagrams and worked examples are effective B2B story formats.

Avoid invented customer stories, unquantified superlatives, borrowed evidence from different ingredients or strains, and any wording that implies treating or preventing disease. Keep the same core facts across every channel.

We provide samples, technical data sheets and certificates of analysis on request, and our ENZYVIVE® service develops custom blends to a brief. These give your team accurate facts on which to build a product story.

Probiotics are live microorganisms that, in adequate amounts, may confer a health benefit. Prebiotics are substrates, often fibres, that are selectively used by beneficial microbes. Postbiotics are preparations of inactivated microorganisms or their components, which do not need to stay alive in the product.

A synbiotic combines live microorganisms with a substrate that is selectively used by microbes, designed so that the two work together. In practice, R&D teams must check that the chosen fibre does not reduce probiotic viability through moisture or other interactions in the final product.

Many candidate strains are strict anaerobes, so even brief exposure to oxygen can reduce viability during fermentation, drying and packaging. Several are also new to the food supply, which means novel food or similar approvals may be required before sale.

Research into the gut-brain axis is active, but claims about mood, stress or cognition are tightly regulated and need strong, strain-specific human evidence. Most brands should keep wording modest and seek regulatory review in each market.

We manufacture a range of probiotic strains, including spore-forming Bacillus species and lactic acid bacteria, plus digestive enzymes that can be combined with them. Samples, TDS and CoA are available on request for formulation trials.

Enzyme supplier qualification is the documented process of confirming that a supplier can consistently deliver enzymes that meet an agreed specification. It usually combines a document review, testing of samples, a risk-based audit, staged trials and ongoing monitoring after approval.

A supplier should normally provide a specification, a certificate of analysis for each batch, a technical data sheet and a safety data sheet. QA teams also ask for quality certificates such as GMP or ISO 9001, and statements on allergens, GMO status, origin and, for animal-derived enzymes, BSE/TSE risk where relevant.

Not always. Many companies use a risk-based approach, where critical materials such as pharmaceutical actives get an on-site or third-party audit, while lower-risk materials may be approved on a questionnaire, certificates and test results. The approach should be defined in the buyer's own quality procedures.

Customers usually expect advance notice of changes to the production strain or source, manufacturing site, process, carrier or excipients, packaging, specification, test methods and key sub-suppliers. The notice period and the list of notifiable changes should be written into a quality agreement.

There is no single rule. A common approach is to test a laboratory sample, then a pilot or plant trial, and then give the first few commercial batches full testing against the specification before moving to reduced testing. The number of batches should be set by the buyer's own risk assessment.

Re-qualification is usually done on a fixed cycle set by the buyer's quality system, and also after significant changes, quality failures or complaints. It typically repeats the document review, checks performance trends and, for higher-risk materials, includes a new audit.

Start by qualifying the supplier on its certificates and documents, then test samples in your own process. Confirm that the product is permitted for your intended use in your country, agree the specification, Incoterm, packaging and payment terms, and appoint a customs broker to clear the shipment on arrival.

Enzymes and prepared enzymes are classified under HS heading 3507. Subheading 3507.10 covers rennet and its concentrates, and 3507.90 covers other enzymes and prepared enzymes. Each country adds its own digits to the six-digit code, so the importer's customs broker should confirm the full national tariff line.

A typical export shipment travels with a commercial invoice, a packing list, a bill of lading or air waybill and, where requested, a certificate of origin. The product documents are usually a certificate of analysis for each batch, plus the technical data sheet and safety data sheet. Some importing countries ask for extra documents, such as permits or health certificates.

The right Incoterm depends on how much of the freight, insurance and customs work the buyer wants to handle. EXW and FCA leave most of the logistics to the buyer, FOB and CIF are designed for sea freight, and DAP places more of the transport responsibility on the seller. The chosen rule should be agreed in writing for each order.

It depends on the strain, the format and the supplier's storage recommendation. Spore-forming probiotics are generally more tolerant of heat and moisture than many lactic acid bacteria, which can be more sensitive. Agree the storage and shipping conditions with the supplier before ordering and store the product as recommended on arrival.

The importer or brand owner is responsible for confirming that an enzyme or probiotic is permitted for its intended use in the destination country. The manufacturer can supply specifications, certificates and technical documents to support that review, but cannot confirm local regulatory status on the buyer's behalf.

A private-label enzyme or probiotic blend is a formulation produced by a contract manufacturer and sold under the buyer's own brand. It may be a ready formulation adapted to the brand, or a fully custom blend developed to the brand owner's brief.

A good brief states the intended use, target markets, product format, dose per serving, the enzyme activities or probiotic strains wanted, and the target activity or viable count at the end of shelf life. It should also list certification needs such as Halal or Kosher, packaging, expected volumes and the documents the brand owner will need for registration.

The brand owner is responsible for the label, the claims and any product registration or notification in each market where the product is sold. The manufacturer supports this with specifications, certificates of analysis, stability data and other technical documents, but the brand owner decides what is said on the pack.

Enzyme activity and probiotic viability decline over time, and the rate of loss rises with heat and humidity. Exported products may be stored in hot or humid climates, so stability should be tested in the final formula and pack under conditions that reflect the target markets, and label claims should be set from those results.

Yes. Enzymes and probiotics are often combined in digestive and gut-health formulations. The combination needs careful control of moisture, because water activity affects both probiotic survival and enzyme stability, and the blend should be tested for both activity and viable count over shelf life.

ENZYVIVE® is the custom-blend service of Enzyme Bioscience, an Indian manufacturer of enzymes and probiotics. It covers blends that combine several enzyme or probiotic activities in one product, formulated to a customer's specification for brand owners and manufacturers.

Enzyme Bioscience Pvt. Ltd. has its manufacturing plant in Surat, Gujarat, India. The company was founded in 2012 and serves customers in 21 countries.

The facility is FDA-registered and follows GMP. The company holds ISO 9001:2015, Halal, Kosher and FSSAI certifications. Details are available on the certification page and on request.

The portfolio covers more than 100 enzymes and probiotic strains for pharmaceutical, food, bakery, feed, textile, detergent and leather applications. Custom enzyme blends are available through the ENZYVIVE® service.

Yes. Samples, technical data sheets (TDS) and certificates of analysis (CoA) are available on request, so you can run trials and complete supplier qualification before placing an order.

Products are supplied in 25 kg or 50 kg HDPE drums for industrial customers, or in retail pouches. Packing requirements can be discussed when you make an enquiry.

It describes combining digestive enzymes and probiotic strains in one product so that each does its own job. Enzymes break down proteins, starch, fats or lactose in food, while probiotics are live microorganisms that may support a balanced gut microbiota. Together they give a single, convenient digestive-support formula.

Yes. In a dry powder or capsule both ingredients are largely inactive until they meet moisture, so they can usually be co-formulated. The key controls are low water activity, compatible excipients and protective packaging, confirmed by real-time stability testing.

In a properly dried blend, interaction is minimal because enzymes need water to work. In liquids or high-moisture formats the risk rises, so check viability and enzyme activity over shelf life. Spore-forming strains such as Bacillus coagulans are generally more robust in demanding formats.

Common choices are protease, amylase, lipase, lactase and alpha-galactosidase, matched to the food the product is meant to help digest. The right pairing depends on the target use, the format and the market, so start from a clear product brief.

State each enzyme by name and activity, and each probiotic by genus, species and strain with the count guaranteed to the end of shelf life. Use wording such as 'may support digestion' that is permitted in the target market, and avoid any claim to treat or prevent disease.

Dextran is a polysaccharide made by bacteria, mainly Leuconostoc, when cut or damaged cane waits too long before crushing. It raises juice and syrup viscosity, slows filtration and boiling, distorts sugar crystals and increases sucrose lost to molasses. Refiners may also penalise raw sugar with high dextran.

It is commonly added to mixed juice or to syrup in the later stages of evaporation. The best point depends on temperature, retention time and where the dextran problem appears. Mills usually confirm the dosing point and dose through trials while monitoring dextran levels.

Sugarcane contains some native starch, which passes into the juice. Starch increases viscosity, slows filtration and crystallisation, and can be carried into raw sugar. A heat-stable alpha-amylase added during clarification or evaporation breaks it down into soluble dextrins and sugars.

Invert sugar is a mixture of glucose and fructose made by splitting sucrose. Invertase does this under mild conditions. The resulting syrup is sweeter than sucrose, holds moisture and resists crystallisation, so it is used in confectionery, bakery fillings and beverages.

No. Enzymes reduce the impact of dextran and starch, but the best results come from preventing them where possible. Short delays between cutting and crushing, clean cane and regular mill sanitation all limit dextran formation, so less enzyme is needed.

Two enzymes do most of the work. A heat-stable alpha-amylase first liquefies the starch into shorter dextrins, then glucoamylase breaks those dextrins down to glucose. A debranching enzyme such as pullulanase is sometimes added to help glucoamylase deal with branch points.

Liquefaction is the hot first stage, where gelatinised starch is thinned by alpha-amylase into soluble dextrins. Saccharification is the cooler second stage, where glucoamylase or maltose-forming enzymes convert those dextrins into the target sugars.

DE stands for dextrose equivalent. It expresses the reducing sugar content of a syrup relative to pure glucose, which is set at 100, while starch is close to zero. A higher DE generally means a sweeter, more fully converted syrup.

Acid hydrolysis needs strong acid at high temperature and produces colour and off-flavour by-products that must be removed. Enzymes act more specifically under milder conditions, which reduces by-products, neutralisation chemicals and refining effort.

Yes. The same amylases and glucoamylases are used to make fermentable sugars for fuel ethanol, to remove starch size from woven fabric before dyeing, and to modify starch for paper sizing and coating.

The main trends are engineered enzymes that tolerate tougher process conditions, computational design that speeds up discovery, wider use of biocatalysis in pharmaceutical manufacture and more enzymatic steps in textiles, detergents and feed. Newer areas such as enzymatic plastic recycling are still being scaled up.

The most widely used method is directed evolution. Scientists create many variants of an enzyme gene, test the resulting enzymes for the property they want, keep the best and repeat the cycle. Rational design based on enzyme structure is often combined with it.

AI and computational tools can predict protein structures and suggest which variants are likely to improve stability or activity. This narrows the number of variants that must be made and tested. The predictions still have to be confirmed in the laboratory and in real process conditions.

Enzymes work under mild conditions, act on specific bonds and are biodegradable proteins. Replacing a harsh chemical step with an enzymatic one can lower process temperatures, reduce chemical use and cut effluent load. The actual benefit depends on the process and should be measured case by case.

Cost, stability under real process conditions, regulatory approval for food and pharmaceutical uses, and scale-up from laboratory to plant are the main hurdles. Application trials with realistic substrates are essential before switching a process.

The gut-brain axis is the two-way communication network between the gut and the brain. It works through the vagus nerve, immune signalling, the stress-hormone (HPA) system and molecules produced by gut microbes. Researchers often call it the microbiota-gut-brain axis to include the role of gut bacteria.

Psychobiotics is a research term for probiotic strains studied for effects on mood, stress or cognition. Evidence comes from animal studies and a growing number of human trials, but results are strain-specific and the field is still developing. The term itself is not a regulated claim.

Yes, most of the body's serotonin is produced in the gut, mainly by enterochromaffin cells in the intestinal lining. However, gut serotonin does not cross into the brain, so it is wrong to say that gut bacteria directly make the brain's serotonin. The relationship is more indirect.

No. Anxiety and depression are medical conditions, and foods and supplements cannot claim to treat or prevent them. Wellness products may use permitted wording such as 'may help support a sense of calm', backed by evidence for the specific strain and approved for the target market.

Digestive enzymes support the breakdown of proteins, carbohydrates and fats, which may support digestive comfort. In gut-brain products they are a supporting component alongside the probiotic strain, not an active for mood. Claims should reflect that digestive role only.

Lactase is an enzyme that breaks lactose, the main sugar in milk, into glucose and galactose. In people it is produced in the small intestine. In dairy processing, food-grade lactase is added to milk products so that the lactose is split before the product is consumed.

Yeast lactases, usually from Kluyveromyces species, work best near the neutral pH of milk. Fungal lactases, usually from Aspergillus species, prefer acidic conditions and are generally more heat-tolerant. The choice depends on the pH and temperature of the product being treated.

Glucose and galactose together taste sweeter than the same amount of lactose. When lactase splits lactose, the total sugar stays about the same but perceived sweetness rises. Some producers remove part of the lactose by filtration first to keep the taste closer to regular milk.

Lactase acts only on lactose, so the protein, fat, calcium and other milk nutrients are largely unaffected. The sugar is present as glucose and galactose instead of lactose. Any nutrition or health claims must follow the regulations in the market of sale.

Yes. Lactase is used in supplement formulations intended for people who have difficulty digesting lactose, usually taken with dairy foods. Fungal lactases are common here because they tolerate acidic conditions. Claims must be worded carefully and comply with local rules.

For enzymes it mainly means correct identity, specified activity, low contaminants, stability and consistent batches. For probiotics it also means a guaranteed viable count at the end of shelf life and a clearly identified strain. All of these should be backed by specifications and certificates of analysis.

Pharmacopoeial grades meet published monographs that define identity, assay and purity tests. Pharmaceutical manufacturers often require them because the tests are standardised and recognised by regulators, which simplifies their own quality control.

Sometimes, for example in technical applications where purity requirements are lower. The decision should rest on fitness for purpose and cost per effective dose, confirmed by pilot trials, rather than price per kg alone.

Ask for the specification, a recent certificate of analysis, the technical data sheet, stability data, allergen and GMO statements where relevant, and copies of quality certifications. For regulated products you may also need a supplier questionnaire or an audit.

Our facility in Surat, Gujarat is FDA-registered and GMP-compliant, and we hold ISO 9001:2015, Halal, Kosher and FSSAI certifications. In-house R&D and QC labs test our enzymes and probiotic strains, and TDS and CoA are available on request.

The names describe the pH range where each enzyme works best. Acid proteases suit acidic processes, neutral proteases work near neutral pH, and alkaline proteases are most active in alkaline conditions. The right choice depends on the pH of your process and the protein you want to break down.

Bitterness comes mainly from peptides with exposed hydrophobic amino acids, which form as proteins are broken down. It depends on the protein source, the enzyme and the degree of hydrolysis. Choosing the right enzyme and stopping at the right point helps control it.

Proteases weaken the gluten network so the dough becomes more extensible and less elastic. Sheets and shapes then hold their dimensions with less shrinkage. Proteases are used as an enzymatic alternative to chemical dough relaxers in many biscuit formulations.

Feed proteases help break down dietary protein that the animal's own enzymes do not fully digest. This can improve protein digestibility, give nutritionists more flexibility with protein ingredients and reduce the nitrogen excreted in manure. Results depend on species, diet and enzyme.

No. Suppliers use different assays and units, often based on different substrates, pH and temperature. Two products with similar numbers may not be equivalent, so compare them in your own application trial rather than on the label value alone.

An enzyme is a biological catalyst, usually a protein, that speeds up a specific chemical reaction. It is not used up, so one enzyme molecule can act on many substrate molecules. Living cells depend on thousands of different enzymes.

An enzyme binds its substrate in a pocket called the active site and holds it in a position that makes the reaction easier. This lowers the activation energy, the energy barrier the reaction must overcome, so the reaction runs much faster at normal temperatures.

Enzymes depend on their folded three-dimensional shape. Above a certain temperature the protein starts to unfold, or denature, and the active site loses its shape. Activity then falls sharply, and the loss is often permanent.

Enzymes are classified into seven classes: oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases and translocases. Hydrolases, which split bonds using water, include amylases, proteases and lipases and are the most widely used in industry.

Most industrial enzymes are made by fermentation, growing selected microorganisms such as fungi or bacteria that secrete the enzyme. The enzyme is then recovered, purified and standardised to a declared activity. Some, such as papain, come from plants, and others, such as pepsin, from animal tissue.

An enzyme activity unit expresses how fast an enzyme preparation converts its substrate under defined assay conditions. The general enzyme unit (U) is the amount of enzyme that converts 1 micromole of substrate per minute. The substrate, pH, temperature and reaction time must be stated, because the value changes if any of them change.

IU is the international unit defined by the International Union of Biochemistry: 1 µmol of substrate converted per minute under defined conditions. In practice IU and U are used interchangeably on most data sheets. Neither tells you the assay conditions, so always check the method behind the number.

Multiply by 1,000, because there are 1,000 milligrams in a gram. For example, an enzyme declared at 50 U/mg contains 50,000 U/g. Convert both offers to the same basis before comparing dose or price, but only when they use the same assay method.

No reliable fixed conversion exists. GDU, TU and HUT are measured on different substrates (gelatin, casein and haemoglobin) at different pH and temperature, so the same protease gives a different number in each assay. Compare such products with a side-by-side application trial instead.

The katal is the SI unit of catalytic activity: the amount of enzyme that converts 1 mole of substrate per second. One enzyme unit equals 1/60 µmol per second, or about 16.67 nanokatal. Katal values are common in scientific papers and some regulatory documents, while industry data sheets usually use U.

No. CFU (colony-forming unit) counts viable microorganisms that can grow into colonies on a plate, so it is used for probiotics, not enzymes. BN is shorthand for billion CFU per gram. It appears on the same specifications because many blends contain both enzymes and probiotics.

In many cases, yes, at least partly. Glucose oxidase can take on some of the strengthening role of chemical oxidants, lipases can replace part of the emulsifiers used for volume and crumb, and protease can replace sodium metabisulphite in biscuit doughs. The replacement level has to be confirmed in bake tests with your flour and process.

Labelling rules differ between countries. In many markets, enzymes that are inactivated during baking are treated as processing aids, but this is not universal and carriers or other ingredients in the enzyme preparation may need declaring. Check the regulations in each market where the product will be sold.

Anti-staling enzymes such as maltogenic amylase keep crumb softer for longer, which can reduce returns of unsold product. Enzymes also help compensate for variation between flour batches, so fewer batches fall outside specification. Smoother machinability on high-speed lines can reduce dough rejects.

Microbial enzymes can be produced for halal and kosher markets when the manufacturer holds the relevant certification and controls the raw materials and carriers. Ask the supplier for current certificates covering the specific product you plan to use.

It depends on the product and the number of variables involved. A typical route runs from lab bake tests against a control, through plant trials, to shelf-life checks before full production. Changing one ingredient at a time and keeping a control makes the results easier to interpret.

The five most widely used are amylase, protease, xylanase, lipase and glucose oxidase. Amylase supports fermentation and crust colour, protease relaxes gluten, xylanase improves handling and volume, lipase improves crumb and dough stability, and glucose oxidase strengthens dough. Maltogenic amylase is also widely used to slow staling.

Fungal amylase is relatively heat-sensitive and is inactivated early in baking, so it mainly acts in the dough and is hard to overdose. Bacterial amylase is more heat-stable and keeps working as the starch gelatinises, so too much can produce a sticky, gummy crumb. They are chosen for different purposes.

Protease partly breaks down gluten proteins, which makes the dough more extensible and less elastic. Sheeted biscuit and cracker doughs then shrink less after cutting and keep a more even shape and thickness. It is also used to replace sodium metabisulphite in some biscuit recipes.

Too much xylanase breaks down more arabinoxylan than needed and releases the water it was holding, so the dough becomes wet and sticky. This causes handling problems on dividers and moulders. The dose should be set by bake tests with the specific flour and process.

Yes. Most commercial bread improvers combine several enzymes, often with ascorbic acid, because their effects complement each other. For example, glucose oxidase can counter the softening effect of xylanase. The balance between them should be tuned to the flour and process.

Most bakery enzymes are proteins that lose activity as the crumb temperature rises during baking. Fungal amylase is inactivated relatively early, while maltogenic amylase and bacterial amylase are more heat-stable and keep working for longer. That difference in heat stability is used deliberately when choosing enzymes.

Staling is mainly caused by starch retrogradation: after baking, starch molecules, especially amylopectin, slowly recrystallise and the crumb firms. Moisture moving from crumb to crust adds to the effect. Bread can stale even when it has not dried out noticeably.

Maltogenic amylase stays active long enough during baking to act on gelatinised starch. It shortens the outer chains of amylopectin, which makes them less able to recrystallise. The crumb therefore firms more slowly and stays soft for longer.

Yes. Without gluten, the crumb structure depends on other proteins, starches and hydrocolloids. Transglutaminase can cross-link proteins such as egg or dairy proteins to build structure, and amylases can help with softness. Results depend strongly on the recipe, so trials are essential.

Bakery enzymes are proteins produced mainly by fermentation of selected microorganisms, and similar enzymes occur naturally in flour and yeast. Whether a product can be described as natural or clean label depends on local labelling rules and the full ingredient list, so check the regulations in your market.

Fungal diastase is used mainly as a starch-digesting ingredient in digestive formulations such as syrups, tablets and capsules. It breaks starch into dextrins and maltose and may support the digestion of carbohydrate-rich meals. It is also used in food processing in non-pharmacopoeial grades.

It is produced by fermentation of the mould Aspergillus oryzae, which secretes amylase into its growth medium. The enzyme is then recovered, concentrated, dried and standardised to a defined activity.

IP grade means the material is made and tested to meet the Indian Pharmacopoeia monograph for fungal diastase. The monograph sets the identity, activity and quality tests a batch must pass, and the results are reported on the certificate of analysis.

Fungal diastase acts on starch and pepsin acts on protein, so together they cover two major food components. This combination is common in digestive syrups and tablets in India. Formulators must check that both enzymes keep their activity in the chosen pH and format.

It should be kept in a tightly closed container in a cool, dry place, away from heat and humidity. Moisture and high temperature reduce enzyme activity over time, so the storage conditions on the TDS and CoA should be followed.

Fungal diastase is an enzyme preparation from Aspergillus oryzae whose main activity is alpha-amylase. So it is a type of alpha-amylase rather than a separate enzyme. The practical differences are between amylases from fungal and bacterial sources, and between pharmaceutical, food and industrial grades.

Bacterial alpha-amylases, especially thermostable types from Bacillus species, tolerate much higher temperatures than fungal amylase. That is why they are used to liquefy starch during cooking, while fungal amylase is chosen where early inactivation is useful, as in baking.

Fungal diastase IP is the grade most commonly used in Indian digestive syrups, tablets and capsules, often alongside pepsin. It is produced and tested to the Indian Pharmacopoeia monograph, which is what pharmaceutical manufacturers need for their dossiers.

Fungal amylase supplies sugars for yeast and improves dough handling, then loses activity as the loaf heats during baking. This limits further starch breakdown in the crumb. A highly heat-stable bacterial amylase can keep working too long and give a sticky crumb.

No. Fungal amylase is often specified in SKB units and bacterial amylase in BAU, and pharmacopoeial grades use their own assay. These methods use different conditions and definitions, so dose comparisons must be made through application trials.

Papain is a protein-digesting enzyme obtained from the latex of unripe papaya fruit (Carica papaya). It is a cysteine protease, which means a cysteine group in its active site does the cutting. It breaks proteins into smaller peptides and amino acids.

Papain is used in digestive enzyme formulations that may support the digestion of dietary protein, often combined with other enzymes. It is also used in cosmetic products for gentle exfoliation. Products containing papain should not claim to cure, treat or prevent any disease.

Papain is used to tenderise meat, to make protein hydrolysates for flavour and nutrition, and to chill-proof beer by breaking down proteins that would otherwise form a haze when the beer is cooled. The food grade is specified for these uses.

Papain IP/USP is produced and tested to pharmacopoeial monographs for use in medicines and health products. Food-grade papain is specified for food processing and declared in units suited to those applications. The grade should match the end use and the regulations that apply to it.

Papain has a long history of use in food processing. Like other protease powders, however, it can cause allergic sensitisation if dust is inhaled repeatedly. Handle it with dust control and suitable respiratory and skin protection, and follow the safety data sheet.

Pharmaceutical enzymes are enzymes made to the quality standards required for medicines, usually defined by pharmacopoeial monographs such as IP, BP, USP or EP. They are used as active ingredients in digestive and proteolytic preparations and as catalysts in drug manufacture.

Pancreatin is a mixture of amylase, lipase and protease obtained from animal pancreas, usually porcine. Veg pancreatin is a blend of plant and microbial enzymes designed to provide similar activities for vegetarian formulations. The two differ in source, activity profile and regulatory status, so they are not automatically interchangeable.

It means the enzyme is made and tested to meet the monograph in the Indian, British, United States or European Pharmacopoeia. The monograph defines identity, activity assay, purity and microbial requirements. Manufacturers choose the grade required by their market's regulator.

Some enzymes, especially pancreatic lipase, lose activity in stomach acid. An enteric coating keeps the tablet or capsule contents intact in the stomach and releases them in the less acidic small intestine, where the enzymes are needed.

Enzymes act as biocatalysts in some API manufacturing steps. They can make specific chemical changes, including producing a single mirror-image form of a molecule, under mild conditions. This can reduce the number of steps, solvents and by-products compared with conventional chemistry.

Serratiopeptidase, also called serrapeptase or serralysin, is a proteolytic enzyme that breaks down proteins into smaller peptides. It is produced by fermentation of Serratia bacteria and is used as an active ingredient in pharmaceutical formulations in several markets.

Serratiopeptidase is used for its anti-inflammatory action in approved medicines where permitted. Its regulatory status varies by country: in some markets it is an approved medicine, in others it is sold under different rules or is not permitted, so each manufacturer must check the position in its own target markets.

Serratiopeptidase IP is serratiopeptidase made and tested to the monograph in the Indian Pharmacopoeia. The monograph sets the identity test, activity assay and purity requirements that each batch must meet, and the results are reported on the batch certificate of analysis.

Check that the certificate of analysis states the pharmacopoeial grade, the batch number and dates, and results for description, identification, activity, loss on drying and any impurity and microbial tests required by the specification. Also confirm that the activity assay method and unit match those in your own specification.

Serratiopeptidase is a protein and loses activity in strongly acidic conditions such as those in the stomach. An enteric coating protects the enzyme as it passes through the stomach and releases it in the less acidic small intestine.

Serratiopeptidase should be stored in tightly closed containers, protected from moisture and heat, under the conditions stated on the supplier's label and technical data sheet. Enzyme powders can cause respiratory sensitisation, so handle them with dust control and the protective equipment set out in the safety data sheet.

The gut-skin axis is the idea that the gut and its microbiota interact with the skin through immune signalling, microbial metabolites and nutrient supply. It is an active research area. Findings so far are promising but specific to particular strains and study designs.

Some specific probiotic strains have been studied for skin end-points such as hydration and barrier function, with encouraging early results. These findings apply only to the strain and dose tested. Products should use cautious wording such as 'may support skin health' and only where the target market allows it.

Proteolytic enzymes such as bromelain and papain help break down dietary protein, which makes them a logical partner for protein- or collagen-based beauty formulas. In topical cosmetics, the same enzymes are used as gentle exfoliants. They are not a substitute for dermatological treatment.

Capsules and sachets are the easiest formats for live probiotics because they can be kept dry. Gummies and drinks are popular, but heat and water make them difficult for most live cultures; spore-forming strains or postbiotics are often used instead.

Claims depend on the market and the product category. In many regions, skin claims for supplements must be authorised or backed by human data, and disease terms such as acne or eczema cannot be used. Have each claim reviewed by a regulatory specialist before launch.

Start from the intended use and format, then look for strains with published data that matches that use. Check that the strain is identified to strain level, not just species, and that it is stable in your format. Ask the supplier for identity, safety and stability documents.

There is no single correct number. The count should match the dose used in studies on that strain and must be guaranteed to the end of shelf life, not just at manufacture. Manufacturers add an overage to cover losses during storage.

They can be, if the strain, drying process and packaging are designed for room-temperature storage and stability data supports the label count. Spore-forming strains are naturally shelf-stable. Non-spore-formers usually need dry, cool conditions or protective packaging.

Each has trade-offs. Capsules give accurate doses and can be acid-resistant, powders suit higher doses and mixing into drinks, and tablets are compact but involve compression stress. Choose the format that keeps your strain viable and suits your consumer.

Expect a certificate of analysis for each batch with CFU count and microbial limits, a technical data sheet, strain identity information and stability data. Facility certifications such as GMP and ISO 9001, plus Halal, Kosher or FSSAI where needed, show that quality systems are in place.

According to the 2021 consensus of the International Scientific Association for Probiotics and Prebiotics (ISAPP), a postbiotic is a preparation of non-living (inanimate) microorganisms, their components or both, that provides a health benefit to the host. It is usually made by fermenting a defined strain and then inactivating it, most often with heat.

Probiotics are live microorganisms, so their benefit depends on staying alive until use. Postbiotics are deliberately inactivated, so they do not need to survive processing or storage. Both must be defined and shown to confer a benefit.

Not on their own under the ISAPP definition. Purified microbial metabolites such as short-chain fatty acids are not counted as postbiotics unless they are part of a preparation that includes inanimate microbial cells or cell components. Older articles often used the term more loosely.

Postbiotics suit formats that are hard for live cultures, such as baked goods, gummies, bars, ready-to-drink beverages and products without a cold chain. They are also used in cosmetics, where ingredients described as ferment lysates are already common, and in pet and animal products.

Most regulations do not yet have a specific category for postbiotics. They are regulated under existing food, supplement, feed or cosmetic rules, and in some markets a new preparation may need novel food or similar approval. Health claims follow the same rules as for any other ingredient.

The most widely used genera are the lactobacilli, Bifidobacterium, Bacillus and the yeast Saccharomyces. Streptococcus thermophilus, Pediococcus and Enterococcus are also used, mainly in food fermentation and animal feed. Each genus has different handling needs and typical applications.

No genus is best for everyone. The genus suggests how robust a probiotic is and where it is normally used, but any benefit depends on the specific strain and dose. Choose a well-documented strain that fits your product and format.

In 2020, taxonomists split the large Lactobacillus genus into 25 genera based on genetic data. For example, Lactobacillus plantarum became Lactiplantibacillus plantarum and Lactobacillus casei became Lacticaseibacillus casei. Lactobacillus acidophilus kept its original name.

Bacillus species form spores, which are dormant, tough structures that tolerate heat, drying and storage well. Lactobacilli do not form spores and are more sensitive to heat and moisture. This makes Bacillus strains a common choice for baked goods, beverages and feed.

Fermented foods such as yoghurt and kefir contain live cultures, but the strains and counts are often not defined or guaranteed. Supplements and probiotic-labelled foods state the strain and count. Both can be part of a balanced diet; they are simply different products.

CFU stands for colony-forming unit. It is the number of viable microbial cells, or small clusters of cells, that can grow into a visible colony on a culture plate. A label stating 10 billion CFU per capsule means the product should contain at least that many viable organisms per capsule, ideally guaranteed to the end of shelf life.

BN means billion CFU per gram. A culture powder of 100 BN contains 100 × 10⁹ CFU in each gram. It is the potency figure you use to calculate how much culture powder each serving needs.

Overage is the extra viable count added at manufacture, above the label claim, to cover losses during processing and storage. Without it, a product that meets its claim on the day it is made may fall below the claim before its expiry date. The amount is set from stability data for the specific strain, format and packaging.

If stability data show that a fraction S of the count survives to the end of shelf life, the overage needed is 1 ÷ S − 1. For example, 80% survival needs a 25% overage and 50% survival needs 100%. Add a margin for processing losses and assay variability, then calculate culture per serving as claim × (1 + overage) ÷ potency.

Probiotic bacteria are living cells that slowly lose viability in storage. Moisture and high water activity, heat, oxygen and stresses such as compression or shear all speed up the loss. Low water activity, cool storage and barrier packaging slow it down.

The more reliable and widely expected practice is to state the count guaranteed until the end of shelf life. A count at manufacture tells the buyer little about what remains when the product is used. Check the specific labelling rules of each market where the product will be sold.

Leather enzymes are proteases, lipases and amylases used in the beamhouse to clean raw hides and skins before tanning. They break down non-collagenous proteins, fats and carbohydrate material that would otherwise affect the quality of the finished leather. They are produced mainly by microbial fermentation.

Bating is the step after deliming in which proteolytic enzymes remove remaining non-collagenous proteins and other debris from the pelt. It gives a cleaner, flatter and softer grain and improves the feel of the finished leather. Bating was historically done with pancreatic enzymes; microbial proteases are now widely used.

Enzymes can reduce the amount of sulphide needed, and enzyme-assisted hair-saving processes loosen hair at the root so it can be removed rather than dissolved. Fully sulphide-free unhairing is possible but needs tight process control and is not yet standard in most tanneries. Trials on your own raw material are essential.

Hides and especially sheepskins contain natural fat, which can cause uneven dyeing, fatty spue and finishing problems if it is not removed. Lipase breaks down these fats so they can be washed out, reducing reliance on solvents and large amounts of surfactant.

Acid bating uses acid proteases that work at low pH, such as on pickled pelts or wet blue. It can improve grain cleanliness and softness at a later stage, which is useful when the earlier bate was not sufficient or for stored pickled stock. Conditions and dose should follow the product TDS.

Textile enzymes are proteins, mostly produced by microbial fermentation, that catalyse specific reactions in fibre processing. Examples are amylase for desizing, pectinase for bio-scouring, catalase for removing residual hydrogen peroxide and cellulase for bio-polishing and denim finishing. They work under milder conditions than many conventional chemicals.

Enzymes act only on their target substrate and work at moderate temperatures and pH. That can reduce the use of caustic soda, reducing agents and pumice stones, lower process temperatures and cut the number of rinse baths. The exact savings depend on the mill's existing process and should be measured.

Warp yarns are often coated with starch size to protect them during weaving. Enzymatic desizing uses amylase to break that starch into soluble fragments that wash out easily. It removes size without the fibre damage associated with harsh acid or oxidative desizing.

Hydrogen peroxide left on fabric after bleaching can interfere with reactive dyeing. Catalase breaks the peroxide down into water and oxygen. This can replace chemical reducing agents and reduce the number of hot rinses needed before dyeing.

Most commercial textile enzymes act on natural fibres or their impurities, such as cellulose, starch size and pectin. On cotton-polyester blends they act on the cotton portion only. Enzymes for synthetic fibres are an area of research rather than routine mill practice.

Bio-polishing is an enzymatic finishing process for cellulosic fabrics such as cotton, viscose and lyocell. Cellulase enzymes weaken the small fibre ends protruding from the yarn surface, and mechanical action in the machine breaks them off. The fabric ends up with a cleaner surface, softer handle and lower tendency to pill.

Yes, the removal of surface fuzz is permanent because the fibres are physically removed. It reduces the fabric's tendency to form new pills, although no treatment makes a fabric completely pill-free. This is different from softeners, which coat the surface and can wash out over time.

Both are used. Bio-polishing before dyeing gives a clean surface for even dye uptake and avoids shade change, while bio-polishing after dyeing can affect the shade and must be tested carefully. Neutral cellulases are often chosen when treating dyed goods because they are gentler.

Bio-polishing removes some fibre, so a small loss of weight and strength is expected. The loss is controlled through enzyme dose, treatment time, temperature and mechanical action. Mills should measure weight loss and tensile or bursting strength during trials and set limits for each quality.

Cellulase only acts on cellulosic fibres, so on cotton-polyester blends it treats the cotton portion. It can improve the surface of the cotton component, but it will not remove pills formed by polyester fibres. Results on blends should be confirmed in trials.
