Product Description

Product Description
Papain
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
๐Ÿฝ Food Industry
Papain is 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.
๐Ÿช 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.
๐Ÿ’Š 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.
๐Ÿงต Textile & Leather Industry
Used for wool shrinkage control and to make leather fine and glossy.
๐Ÿ„ Feed Industry
Improves feed utilization rate, reduces feed costs, stimulates appetite, and promotes animal growth.
๐Ÿงด 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.
โœจ 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.
