  • What's Papain Extract 

Papain is a natural enzyme, a kind of endopeptidese containing hydrosulfide group (-SH), extracted from the milky juice of the unripe papaya by biotechnology. It has strong ability of hydrolyzing protein and can be used for improving the nutritional value or function of the plants and the animal protein. The strict concentration limit of microbe and heavy metal by using the biotechnology and the membrane separation technique, can achieve the pharma and food grade.

We also can supply the Papain in other enzyme activity units, such as TU/mg, USP unit/mg, MU/mg, and iu/mg.



1) Papain breaks down tough meat fibres, and has been used for thousands of years to tenderize meat eaten in its native South America.

2) Papain can be used to dissociate cells in the first step of cell culture preparations.

3) It is also used as an ingredient in various enzymatic debriding preparations, notably Accuzyme. These are used in the care of some chronic wounds to clean up dead tissue.

4) Papain is also used in some toothpastes and mint sweets as a tooth whitener.
