Papain

Introduction
Papain is a natural enzyme, a kind of endopeptidase enzyme containing hydrosulfide group (-SH), and its molecular weight is 21000, it is composed by 212 amino acid. Papain is extracted from the milky juice of the unripe papaya by biotechnology. It has protease, esterase activity and broad specificity. It has strong ability of hydrolyzing protein, polypeptide, ester, acid amide and strong synthetic capacity which can combine protein hydrolyzate into protein substances. this can be used for improving the nutritional value or function of the plants and the animal protein.

Application
1)Papain can hydrolyze the macromolecular protein of food into small peptides and amino acid by the enzymatic reaction. Papain can be applied on hydrolyzing animal protein and plant protein, soybean etc. Papain can be used for meat tender enzyme, brewing clarification, biscuit crisp, healthy food, soy sauce fermentation and brewing. Papain can improve the nutritional value, reduce the cost and help digest system assimilate food. Papain can be widely used in chicken, pork, beef and seafood's protein hydrolyzing. 
2)the medicine such as papain tablets, papain eating throat tablets, papain digestive capsule etc. Made from papain compound can help ease swelling, alleviate inflammation, improve immunity, and promote digestion. Papain can be used for test erythrocyte surface and blood group identification. It can treat gynecological disease, glaucoma and insect bites.
3)Wool shrinkproof:the wool which has treatment with papain will be more tensile and soft. Papain can be applied on degumming and refine of silk.
4)Leather Industry 
Depilatory made by papain will make the leather shinier.
