摘要

PROBLEM TO BE SOLVED: To provide a collagen peptide-containing solution which is produced from a safety raw material and has a high commodity value.;SOLUTION: Crude collagen prepared by deliming fish scales (hard fish scales) is properly hydrolyzed in an aqueous alkali solution containing an alkali salt (e.g. sodium bicarbonate) under a pressurized atmosphere with a pressure slightly lower than 2 atm. The resultant product is neutralized with an organic acid and dehydrated by spray drying to obtain a powder.;COPYRIGHT: (C)2004,JPO
