METHOD FOR PRODUCING LOW-MOLECULAR COLLAGEN

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a low-cost low-molecular collagen at a high yield and friendly to the environment by using waste of boiled extraction residues.

SOLUTION: The method for producing a low-molecular collagen comprises decalcifying fish scale, boiling and extracting collagen in hot water at 90-100°C to give an extraction residue as a raw material, with the treating of the extraction residue with an acidic protease being a proteolytic enzyme and decolorizing the treated residue with activated carbon.
