Product Name:Papain
English Name:Papain
CAS No.:9001-73-4
Aliases:Papaya enzyme, Papayotin
Physical Properties:White to light yellow powder, slightly hygroscopic, readily soluble in water, soluble in glycerol; aqueous solution is colorless or light yellow, sometimes milky white. Almost insoluble in organic solvents such as ethanol, chloroform and ether. It is a sulfhydryl (-SH) endopeptidase with protease and esterase activities. Optimum pH 6.0~7.0 (generally active at pH 3~9.5), isoelectric point pI 8.75; optimum temperature 55~65°C (generally active at 10~85°C), not completely inactivated at 90°C. Molecular weight approximately 23,400, composed of 212 amino acid residues. Inhibited by oxidizing agents and activated by reducing substances.
Uses:As a proteolytic enzyme, it is widely used in the food industry for beer chill-proofing and clarification, meat tenderization, hydrolysis of animal and plant proteins, and production of health products. In the pharmaceutical industry, it is used for anti-inflammatory, digestive aid, wound healing promotion and debridement of necrotic tissue. It is also applied in cosmetics, daily chemicals, feed and leather processing.
