Product Description

Product Description

Papain 1
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.

Functions & Applications

  • 🍔
    Food Industry: Papain widely used for the hydrolysis of animal and plant proteins from chicken, pork, beef, seafood, blood products, soybeans, peanuts, etc. It serves as a meat tenderizer, wine clarifier, biscuit loosening agent, noodle stabilizer, health food ingredient, as well as for soy sauce brewing and alcohol fermentation. It improves food nutritional value while reducing production costs.
  • 🍪
    Biscuit Industry: 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.
  • 💊
    Pharmaceutical Industry: 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.
  • 🧵
    Textile & Leather Industry: Used for wool shrinkage control and to make leather fine and glossy.
  • 🐄
    Feed Industry: Improves feed utilization rate, reduces feed costs, stimulates appetite, and promotes animal growth.
  • 🧴
    Daily Chemical Industry: Used in soaps, detergents, hand sanitizers, etc., with strong decontamination and disinfection effects. It can also be added to oral care products.
  • 💄
    Cosmetics Industry: Papain acts on aged cuticles of human skin to promote decomposition and shedding. It inhibits melanin production and provides whitening and anti-freckle effects.

Frequently Asked Questions (FAQ)

QWhat is papain and where does it come from?
Papain is a natural proteolytic enzyme extracted from the latex of unripe papaya (Carica papaya) fruit using bioengineering technology. It possesses both protease and esterase activities and is widely used across food, pharmaceutical, textile, cosmetics, and other industries.
QWhat enzyme activity levels are available for papain powder and liquid?
Our papain powder is available with enzyme activity ranging from 50,000 u/g to 3,000,000 u/g, and the liquid form ranges from 50,000 u/ml to 800,000 u/ml. Custom activity levels can be provided upon request, including TU/mg, USP unit/mg, IU/mg, and MU/mg.
QWhat are the optimal conditions for using papain?
Papain is effective within a pH range of 3.5–9, with an optimum pH of 5–7. The effective temperature range is 20–80°C, with the optimal temperature being 55–60°C. The recommended dosage is 2–3‰, though the actual dosage should be adjusted based on specific production conditions.
QHow should papain be stored to preserve its enzyme activity?
Papain should be stored at 0–25°C in a cool, dry place away from direct light. Refrigeration is recommended for best results. Avoid high temperature and high humidity environments, as these conditions may reduce enzyme activity over time. If stored under unfavorable conditions, the dosage should be increased appropriately.
