Description

Papain CAS NO 9086-65-1 is a proteolytic enzyme derived from the latex of the papaya fruit (*Carica papaya*). This versatile enzyme is valued for its ability to break down proteins, making it a critical processing aid across multiple industries. Key sectors that rely on papain include food & beverage processing, pharmaceuticals, cosmetics, and leather manufacturing for its efficacy and natural origin.

Application

• Food & Beverage Processing: Used as a natural meat tenderizer, in beer and wine clarification (chill-proofing), and for modifying dough texture in baking.
• Pharmaceutical & Nutraceutical: Employed in digestive aid formulations, anti-inflammatory preparations, and as a debriding agent in wound care products.
• 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 wool industry to prevent shrinkage.
• Biotechnology & Research: Utilized for cell isolation and tissue dissociation in laboratory protocols.
• Diagnostic Reagents: A component in certain diagnostic kits and biochemical assays.
