METHOD FOR PRODUCING COLLAGEN PEPTIDE FROM BONITO BONE AS RAW MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a production method in which collagen peptide having a blood-pressure-lowering effect is obtained by using collagen with stable quality produced from fish as raw material.

SOLUTION: The method for producing collagen peptide includes at least: a step of immersing bonito bone in a basic aqueous solution; a step of immersing the bonito bone in an acid aqueous solution; a step of converting collagen contained in the bonito bone into gelatin at a temperature ranging from 80 to 150°C for hot-water extraction; a step of obtaining, after the hot-water extraction step, gelatin extraction solution by removing the insoluble; and a protein dissolving step of mixing the gelatin extraction solution and the protein splitting enzyme, and reacting the mixture at a temperature of 30-70°C for 30 minutes to 24 hours; and a step of deactivating the protein splitting enzyme.
