Papain is a natural enzyme product extracted from unripe papaya fruit using bioengineering technology. It possesses both protease and esterase activities with broad substrate specificity, offering strong hydrolysis capabilities towards animal and plant proteins, polypeptides, esters, and amides. It also exhibits synthetic activity, enabling the recombination of protein hydrolysates into protein-based substances. This property can be used to improve the nutritional value and functional properties of animal and plant proteins.
As a natural enzyme preparation, papain is a protein. Consuming food products containing this enzyme is as safe and beneficial to human health as eating protein-rich foods.

Widely used for the hydrolysis of animal and plant proteins from chicken, pork, beef, seafood, blood products, soybeans, peanuts, etc. Serves as a meat tenderizer, wine clarifier, biscuit loosening agent, noodle stabilizer, and more. Improves nutritional value while reducing production costs.
Reduces the wet gluten strength of dough, improves dough plasticity and physical/chemical properties, corrects flavor impacts from chemical additives, and effectively enhances biscuit quality.
Medicines containing papain — such as papaya throat lozenges, enteric-coated tablets/capsules, and buccal tablets — provide anti-inflammatory, cholagogic, analgesic, digestive, and immune-boosting effects.
Used for wool shrinkage control and to make leather fine and glossy.
Improves feed utilization rate, reduces feed costs, stimulates appetite, and promotes animal growth.
Used in soaps, detergents, hand sanitizers, etc., with strong decontamination and disinfection effects. Can also be added to oral care products.
Acts on aged cuticles of human skin to promote decomposition and shedding. Inhibits melanin production and provides whitening and anti-freckle effects.
Selected premium raw materials ensure stable enzyme activity.
Proprietary enzyme protection technology developed in-house; papain activity exceeds 3,500,000 units per gram.
Ultrafiltration technology is adopted for efficient separation of papain, with a protease recovery rate of over 90%.
Own manufacturing facility; supports customized specifications.
Certified by FCC, FDA, HALAL, KOSHER, and more.
Effective pH range: 3.5–9
Optimum pH: 5–7
Effective temperature range: 20–80°C
Optimum temperature: 55–60°C
Recommended: 2–3‰
The optimal dosage should be determined based on actual production conditions.
Storage temperature: 0–25°C. Store in a cool, dry place away from light; refrigeration is recommended to preserve enzyme activity.
Extended storage or unfavorable conditions may reduce enzyme activity. If stored under high temperature or humidity, the dosage should be increased appropriately during use.
