Product Introduction:
The papain also is known as papaya proteinase or papaya enzyme, It is a low-specificity proteolytic enzyme extracted from the milky juice of unripe papaya (Carica papaya) by biotechnology. Its appearance is light yellow to white powder, slightly hygroscopic, soluble in water and glycerin, the aqueous solution is colorless or milky white, almost insoluble in organic solvents such as ethanol and ether. Green papaya extract papain contains both strong protein hydrolysis catalytic activity and curds and lysozyme activity, also with the function of lipolysis and protein synthesis, mainly catalytic protein hydrolysis, also can break down the small peptide, can be used for improving the nutritional value or function of the plants and the animal protein. The active center of papain contains cysteine, which belongs to the thiol protease. It has high enzyme activity, good thermal stability, natural hygiene and safety, widely used in food, medicine, feed, daily chemical, leather and textile industries.
Applications:
1. Pharmaceuticals: help ease swelling, alleviate inflammation, relieve pain, improve immunity, promote digestion and diminish intestinal parasite.
2. Cosmetics and daily chemicals: soap, facial cleanser, body wash,shampoo,etc, with papain ingredient, help whitening the skin, remove cuticle, making the skin soft and elastic, tender and full of vigor, Used in washing powder, hand wash, etc, helps care hands.

Food Industry: Papain can hydrolyze the animal and plant protein, as well as placenta and bean, thus , the papain can be made into softener for biscuits, tenderizer for meat and purifying agent for beer and wine ferment etc. It is widely used in wine brewing industry, soy making and beverage manufacturing industry.
4. Feed industry:Papain can be widely used as additives in the forages for such animals as pigs, oxen, sheep, chicks, ducks, geese, fish, shrimps, eels and cows to increase the availability and inversion of protein, decreasing gthe cost for forages and exploiting sources of protein.
5. Leather industry: The papain can be made into depilatory for tanning the leathers, making the products smooth and exquisite with good texture.
