Enzymes are biological catalysts that accelerate specific biochemical reactions. In dairy enzymes, they deliver measurable results without harsh chemicals.

Bulk Production Ready

Stable activity levels and scalable volumes designed for continuous dairy manufacturing lines.

Food Grade Compliance

Food grade dairy enzymes with clear specifications, activity units, and documentation for regulatory review.

Reliable Global Supply

Consistent batch quality and dependable export logistics for long-term supply contracts.

Enzyme Types for Dairy Applications

Select the right enzyme for your process. We supply single enzymes and multi-enzyme blends for dairy enzymes applications.
Chymosin

Coagulates milk proteins to form curd — the essential first step in cheese production.

Lipase

Develops characteristic flavour in aged cheeses by selectively hydrolyzing milk fat.

Lactase

Converts lactose to glucose and galactose for lactose-free milk, yogurt, and ice cream.

Neutral Protease

Accelerates cheese ripening to develop texture, mouthfeel, and depth of flavour.

Catalase

Eliminates hydrogen peroxide residues in milk after antimicrobial treatment, ensuring product safety.

Dairy Enzyme Guide: Functions, Dosage & Applications

Chymosin (Rennet)

Milk Coagulation for Cheese Manufacturing

Function: Chymosin is a protease that specifically cleaves kappa-casein at the Phe105–Met106 bond, destabilizing casein micelles and triggering milk gelation. Microbial chymosin (fermentation-produced) is functionally identical to calf rennet and is the most widely used coagulant in industrial cheese production worldwide.

Typical dosage: 0.01–0.03 g/L milk. Activity typically expressed as IMCU (International Milk Clotting Units). Dosage varies with milk temperature (28–34°C optimal), pH (6.4–6.6 optimal), and calcium ion concentration. Higher calcium accelerates coagulation.

Applications: Hard cheese (Cheddar, Gouda, Parmesan), semi-hard cheese, soft cheese (Brie, Camembert), fresh cheese, quark. Preferred over animal rennet for kosher/halal-certified production.

Lipase

Lipolysis for Cheese Flavor Development

Function: Lipase hydrolyzes milk triglycerides into free fatty acids (FFA), which are the primary drivers of flavor in aged and specialty cheeses. Short-chain FFAs (C4–C8) produce sharp, piquant notes in Romano and Parmesan. Medium-chain FFAs (C10–C12) develop creamy, buttery character in softer varieties.

Typical dosage: 0.002–0.05% w/w of milk. Pre-gastric esterase (PGE) from kid/lamb produces traditional piquant notes; microbial lipases offer more controlled, consistent activity. Overdosing causes soapy off-flavors — critical to validate at scale.

Applications: Italian hard cheeses (Parmesan, Romano, Pecorino), Blue cheese, enzyme-ripened varieties, butter flavor enhancement. Also used to accelerate ripening in industrial Cheddar production.

Lactase (Beta-Galactosidase)

Lactose Hydrolysis for Lactose-Free Dairy Products

Function: Lactase cleaves lactose into its constituent monosaccharides — glucose and galactose. Since ~65% of the world population has reduced lactase persistence after childhood, lactose-free dairy is one of the fastest-growing product segments globally. The resulting glucose/galactose also improves sweetness perception without added sugar.

Typical dosage: 0.01–0.10% v/v (liquid enzyme) at 4–6°C for cold hydrolysis (6–12 hours), or 0.001–0.01% at 35–40°C for warm hydrolysis (30–60 minutes). Cold-hydrolysis is preferred commercially — can be added to pasteurized milk in-line.

Applications: Lactose-free UHT milk, lactose-free yogurt, lactose-free ice cream, whey permeate processing, low-lactose infant formula. Also improves texture in yogurt by reducing lactose crystallization.

Neutral Protease

Cheese Ripening Acceleration & Bitterness Reduction

Function: Neutral protease hydrolyzes casein and whey proteins at neutral pH (6.0–7.5), releasing peptides and amino acids that drive cheese flavor development. Unlike alkaline protease, it produces fewer bitter peptides, making it preferred for accelerated cheese ripening applications where off-flavor control is important.

Typical dosage: 0.001–0.01% w/v of milk or curd. For ripening acceleration, enzyme is added to the curd milling stage or injected post-pressing. Activity: 50,000–400,000 U/g. pH optimum 6.0–7.0.

Applications: Accelerated Cheddar ripening (reduces maturation time by 30–50%), cream cheese, processed cheese manufacturing, milk protein hydrolyzates for infant formula. Also used in flavor enzyme blends.

Catalase

Hydrogen Peroxide Removal in Cold-Pasteurized Dairy

Function: Catalase decomposes hydrogen peroxide (H₂O₂) into water and oxygen. In markets where H₂O₂ is approved for cold pasteurization of raw milk (US FDA 21 CFR, various Asian regulations), residual H₂O₂ must be neutralized before further processing. Catalase provides rapid, complete decomposition without thermal treatment.

Typical dosage: 100–300 U/L of treated milk. Contact time: 10–30 minutes at 4–8°C before downstream processing. Confirm complete H₂O₂ removal with peroxidase activity test strip or titration.

Applications: H₂O₂-treated raw milk, cheese production in markets using cold pasteurization, milk powder processing, whey treatment. Also used in textile and food processing to remove H₂O₂ from bleaching steps.

Frequently Asked Questions

We supply chymosin (microbial rennet), lipase, lactase (beta-galactosidase), neutral protease, and catalase — all food-grade with activity certificates. Other dairy processing enzymes available on request. TDS and CoA provided for every product.
Chymosin (also called rennet) cleaves kappa-casein in milk, causing the casein micelles to coagulate into a gel (curd). This is the first step in all natural cheese production. Microbial chymosin from fermentation is functionally identical to calf rennet and is preferred for industrial production, kosher, and halal-certified cheese. Dosage: 0.01–0.03 g/L milk at 28–34°C.
Animal rennet (from calf stomach) contains chymosin plus pepsin, producing a slightly different flavor profile in aged cheese. Microbial chymosin (from Aspergillus niger or Rhizomucor miehei fermentation) has higher specific activity, more consistent performance, no animal-derived components, and is accepted for vegetarian, kosher, and halal cheese. Both produce identical coagulation at equivalent IMCU dosage.
Yes. For lactose-free yogurt, lactase is added after pasteurization (before fermentation) or to the finished yogurt. For ice cream, cold hydrolysis (4–6°C, 6–12 hours) is preferred — the resulting glucose/galactose improves sweetness and reduces lactose crystallization in frozen products. Dosage: 0.01–0.10% v/v depending on temperature and target residual lactose level (typically <0.01% for \"lactose-free\" labeling in most markets).
Typically 100–300 U/L of milk treated with H₂O₂. Contact time is 10–30 minutes at 4–8°C. Confirm complete decomposition with a peroxidase activity strip or iodometric titration before downstream processing. Excess catalase has no negative effect — the enzyme is denatured by subsequent pasteurization.
Yes. Every dairy enzyme product is supplied with a technical data sheet (TDS) specifying activity, pH and temperature optimum, recommended dosage, storage conditions, and shelf life. Certificates of Analysis (CoA) are issued per production batch. Contact us for TDS files before ordering.
MOQ is 1 kg for standard enzyme powders and 5 L for liquid enzyme concentrates. Custom blends start at 5 kg. We supply dairy manufacturers, cheese producers, and ingredient distributors of all sizes.
Application method depends on the enzyme: chymosin is diluted in cool water and added to temperature-controlled milk under agitation; lactase is added post-pasteurization for cold hydrolysis; catalase is added to H₂O₂-treated milk and allowed to react before further processing; protease is added to curd at the milling stage. We provide application guidance with every order.
Most dairy enzyme powders have a shelf life of 12–24 months at ≤25°C in sealed packaging. Liquid enzyme concentrates typically last 12–18 months at 2–8°C. Full shelf life data is stated on each TDS. Opened containers should be resealed and used promptly.
Yes. We can formulate multi-enzyme preparations for specific dairy applications — for example, combined chymosin + lipase blends for flavor-accelerated cheese, or lactase + neutral protease for infant formula protein hydrolysis. MOQ for custom blends: 5 kg. Lead time: 2–4 weeks.
