Indications and Usage
Papain is the natural bio-enzyme extracted from white latex of unripe carica papaya skin through modern biological engineering technology. It is –SH containing peptide chain endonuclease, which has the activity of prolease and esterase, wide specificity, and relatively strong hydrolysis ability to animal and plant protein, polypeptide, ester, and acid amide; it also has synthesis ability, which can synthesize protolysate into proteinoid. It is soluble in water and glycerine, the color of solution is either transparent or light yellow, sometimes milky white. It is almost insoluble in such organic solvents as ethanol and chloroform; it is best used when PH=5.7 (useful between 3 to 9.5), and also functional at neutral or slight acid PH value; isoelectric point is *8.*5; most suitable temperature is ****0°C (but it is functional between *0 °Cto *5°C); good heat resistance, will not completely lose activity even at *0°C; suppressed by oxidants and activated by deoxidizers. Papain has the characteristic of high enzyme activity and strong thermal stability; it is safe and sanitary to use as well. It has been extensively applied in numerous industries, such as food, cosmetics, pharmaceutical and health care, household chemical products, feeds, leather, and textile to effectively improve product’s quality and grade and lower production cost at the same time.
