Description

Papain CAS NO 9001-73-4 is a proteolytic enzyme complex derived from the latex of the papaya fruit (*Carica papaya*). This powerful enzyme is valued for its ability to break down proteins, fats, and carbohydrates, making it a versatile processing aid across multiple industries. Key industrial users include manufacturers in the food & beverage, pharmaceutical, cosmetic, and leather processing sectors who require a natural and effective biocatalyst.

Application

• Food & Beverage Processing: Used as a natural meat tenderizer, in beer and wine clarification (chill-proofing), and for hydrolyzing proteins in dietary supplements.
• Pharmaceutical & Nutraceutical Manufacturing: Employed in digestive aid formulations, anti-inflammatory topical preparations, and as a debriding agent for wound care.
• Cosmetics & Personal Care: Incorporated into exfoliating facial peels, enzymatic cleansers, and toothpaste for its gentle protein-dissolving properties.
• Leather & Textile Industry: Applied in the bating process to soften hides and in the enzymatic treatment of wool to prevent shrinkage.
• Biochemical Research & Diagnostics: Utilized as a tool enzyme in cell isolation procedures and protein digestion for analysis.
• Dairy Processing: Aids in the prevention of oxidized flavor in milk and can be used in cheese production.
