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.

Papaya extract contains papain is resistance to cancer, tumor, lymphatic leukemia, bacteria and parasite, tubercle bacillus; Papaya extract is good for gall, and they can kill pains and help with digestion.-Papaya extract is also helpful to treat gynecopathy, glaucoma, and hyperosteogeny, heal wounds from gunshots or knife cuts;identify blood type, and treat insect stings.

1. Health food
The drugs containing papain have the functions of anti-cancer, anti-tumour, anti-lymphatic leukemia, anti-lysogenic bacteriums and anti-parasite, anti-tubercle bacillus and etc. It can diminish inflammation lidan pain helps digestion, treatment women’s illnesses, glaucoma, osteoproliferation, Gun knife wound healing, Blood type identification, Mosquito bites and so on. 


2. Food Industry 
By adopting enzymatic reaction, can make Food macromolecules hydrolysis into small molecular peptide or amino acids, to effectively transform protein, greatly improve the food nutrition value, be helpful for the absorption and digestion of human body. 

3.Beauty and Cosmetics Industry 
Add papain in to cosmetic which contains protein, oils and fats, has special functions of whitening tinder skin, beautify, health care, dispel spot remove dirt, improve metabolism, improve skin and etc. Can be made to diet tea, skin care products and etc.

4. Daily cosmetic products 

Be used in fancy soap, soap, detergent, washing powder and etc, remove stains more efficiently, disinfection, sterilization.

5. Feed Industry 

Used for feed additives, development protein source. Benefit for absorb, increase the utilization rate of feed, save cost, Help the animal digestion, quicken the growth. 

6. Leather Industry 
Can make depilating agent, tanned leather with papain. 
In Textile industry, can be used to treatment wool, Silk refining, can have functions of soft handfee, comfortable, resistance to contraction and etc. 


7. Cell Culture 
Papain in preparation for the cell cultures (cell culture) the first step, in be used to separate cells. Hydrolysis processing small tissue mass after 10 minutes, you can connect to the cells of the extracellular matrix interrupt; Then use protease inhibitors to stop reaction, to prevent further papain cracking cells themselves; With the Pasteur pipette will organize piece of features into single cell suspension. 


8. Immunology 
In immunology, papain can be used to will be immune globulin (i.e. antibody) Fc footage (can crystallization) and Fab footage (the antigen) cut open.

1. Papaya extract is applied for hydrolyzing animal and plant’s protein, making tenderizer, hydrolyzing placenta and soybeans,making cracker swelling agent, noodle stabilizer, beer and beverage clarifier, premium oral medicine, health care products, soysauce, and wine starter.
2. Papaya extract can effectively convert protein, greatly improve food’s nutrition value, and lower cost; Papaya extract is also beneficial for body digestion and absorption.
