The eating and drinking item and the cosmetics null fishskin which contain the collagen peptide of the Pisces origin which is obtained by the production manner and the said production manner of the collagen peptide of Pisces

摘要

PPROBLEM TO BE SOLVED: To obtain a collagen peptide derived from fishes, suitably usable for a food and drink and a cosmetic, hardly having taste and smell peculiar to the fishes, and having excellent safety, and to provide a method for producing the collagen peptide, and the food and drink and the cosmetic containing the collagen peptide. PSOLUTION: The collagen peptide derived from the fishes, containing ≤1.0 wt.% free amino acid and ≤2 ppm arsenic based on the solid is obtained by preparing an extract containing the collagen from fish skin and/or fish bone, enzymically hydrolyzing the extract, and concentrating and purifying the hydrolyzed product by using a reverse osmosis membrane. The food and drink, and the cosmetic are obtained by formulating the collagen peptide. Preferably, the collagen peptide has 1,000-10,000 average molecular weight. A step for decoloration or deodorization of the extract containing the collagen or the enzymically hydrolyzed product is preferably included. The reverse osmosis membrane preferably has 10-50% stopping ratio of sodium chloride. PCOPYRIGHT: (C)2003,JPO
