Introduction
Papain is a natural biological enzyme preparation extracted from the unripe pulp of papaya through bioengineering technology. It is mainly composed of papain, papaya rennet A, papaya rennet B, papaya peptidase B, and other proteolytic enzymes. Papain consists of 212 amino acids and has a molecular weight of 27000.
Characteristics
The active center of papain contains cysteine, making it a sulfhydryl-containing endoprotease with protease and esterase activities. It exhibits strong hydrolysis ability towards animal and plant proteins, peptides, esters, amides, etc. Due to its high enzyme activity, good thermal stability, and natural safety, papain finds wide applications in food, medicine, feed, daily chemical, leather, and textile industries.
The product has good water solubility, no odor, and is easily soluble in water and glycerol. The aqueous solution is colorless or light yellow, sometimes milky white, and almost insoluble in organic solvents.

Applications
• Meat Tenderization
Papain can hydrolyze muscle fiber and collagen into small molecule peptides or amino acids, making the meat tender, crisp, and easily absorbed.
• Beer Clarification
Papain further hydrolyzes proteins in beer, producing more peptides or amino acids, resulting in clearer wine and improved taste. (Recommended dosage: 0.08mg/100mL of papain in beer during frozen storage for better clarification)
• Baking Industry
Papain reduces dough tenderness by hydrolyzing flour protein, ensuring well-formed baked goods and enhancing flavor while reducing oil and sugar content through the Maillard reaction.
• Spice Production
Papain hydrolyzes animal and plant proteins for condiment production, such as chicken essence, oil, soy sauce, and mushroom essence.
• Medicine and Health Care
Papain is used in pharmaceuticals and health care to hydrolyze specific proteins into peptides or amino acids, like collagen peptide and soybean peptide production.
• Feed Processing
Adding papain to feed enhances nutritional value, reduces feeding costs, and improves taste and quality of pet food by hydrolyzing meat protein scraps.
• Daily Chemical Industry
Papain is utilized in toothpaste to enhance cleaning, in facial cleansers for exfoliation, and in skin care products to reduce pigmentation formation and delay aging.
