Papain, also known as papaya proteinase, is a cysteine protease (EC enzyme present in papaya (Carica papaya) and mountain papaya (Vasconcellea cundinamarcensis). Papain is usually produced as a crude, dried material by collecting the latex from the fruit of papaya tree. A purification step is used to remove contaminating substances through a government-registered process, and than ultra purification and concentrated by refined spray.
Our ultra refined papain powder was produced by tapping the latex from the fruit of Carica papaya. The latex under goes various steps of filtration, micro filtration, ultrafiltration and polishing filtration. It is finally spray dried into a free flowing white color powder. Our papain enzyme is mainly used for the baking, brewery, and protein hydrolysis. etc.

This product was produced by Saccharomyces cerevisiae strain, which fermented in submerged medium.


  • Food grade, GRAS, high security;
  • High activity 100,000 U-600,000 U/g;
  • This papain product could digest most protein substrates more extensively than the pancreatic proteases.

Storage: we recommend to store the product under the environment with temperature <25oC, humidity <50%, and its better the temperature within 4oC-10oC.We recommended you use up the enzymes in 5 months under <25oC conditions, and 10 month under 4oC-10oC conditions.

【Food industry】
Hydrolyze protein from food’s giant molecules into peptide or amino acid through enzymic reaction.
Applied for hydrolyzing animal and plant’s protein, making tenderizer, hydrolyzing placenta and soybean, making cracker swelling agent, noodle stabilizer, beer and beverage clarifier, premium oral medicine, soy sauce, and wine starter.
It can effectively convert protein, greatly improve food’s nutrition value, and lower cost; it is also beneficial for body digestion and absorption.

【Feeds Industry】
Used for feeds additives to explore protein source;
It helps with absorption, improves feeds utilizatin rate, saves cost, and aids animal digestion and growth.
It can be added into feeds for pig, cow, sheep, chicken, duck, goose, fish and shrimp;
