Papain is a natural enzyme, it is a kind of endopeptidase enzyme containing hydrosulfide group (-SH), and its molecular weight is 21000. It has strong ability of hydrolyzing protein, polypeptide, ester, acid amide and strong synthetic capacity which can combine protein hydrolyzate into protein substances,which can be widely used for industries such as food processing,medical health and feed industry etc.


Processing Technology

With the advantage of the rich papaya resource of our papaya base, Our papain has already reached the Pharmaceutical Grade and exporting standard by using membrane separation technology and vacuum freeze-drying technology tocontrol microbialand improve the purity of enzyme activity.The highest activity is 2000TU/mg or 120000USP u/mg which is the highest activity in the global market.


Papain has passed the audit of ISO9001:2008, ISO22000:2005,Kosher, Halal etc. Established advanced enzyme analysis & detective equipment,focus on environment protection,persistent on research & development of natural plant enzyme product to ensure safety and non-toxic,to make sure that our Papain can reach the national and exporting standard.


Food Industry:

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. Animal and plant proteolysis: the degree of hydrolysis is above 55%, AN dry matter content exceeds 4.5g / 100g (dry goods). 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.


Papain can hydrolyze the macromolecular protein of biscuit into small peptides and amino acid by the enzymatic reaction. Therefore papain can reduce the flour dough’s gluten, improve its plasticity and physicochemical property. And amino acid is helpful for sugars and amino substances to have complex maillard reaction which make the biscuit’s colour more gold. The using of papain can reduce 10%-25% sodium metabisulfite’s dosage thus can reduce the residual quantity of SO2. So papain can improve biscuit’s quality.

3. Pharmaceutical Industry:

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. Anti-inflammatory, gallbladder, analgesia, aid digestion, improve immunity and other effects.

Textile Industry

Woolshrinkproof:The wool which has treatment with papain will be more tensile and soft. Papain can be applied on degumming and refine of silk.

Leather Industry

Depilatory made by papain will make the leather shinier.

Forage Industry:

Papain can be put in the forage’s formulation or directly put in the forage. It is helpful for promoting digestion of animals, improving the utilization of the feed, cutting the cost of feeding and accelerating the growth. Papain can be advanced compound fertilizers’ additives for vegetables and fruit.

Personal Care Chemicals Industry:

It can be used for perfumed soap, washing soap, detergent and hand sanitizers etc. If the clothing is dirty by bloodstain, milk, juice, sauce and oil, it is hard to remove this stain. However, adding some papain can remove easily. Therefore the papain has strong detergency, sterilization disinfection and it is safe to use.

8. Cosmetics Industry:

Papain can reduce the tyrosine vitality and remove the melanin. Papain can have some good influence on collagen, by which it can assist to fade freckles and enable the skin to appear even and white, protect the the cutin, accelerate the metabolism of epidermis cells and make skin-tendering.

Papain can be added in toothpaste, mouthwash, dentifrice. It can clean mouth and remove tartar and dental calculus.
