Imidazole dipeptides-rich seafood extract, imidazole dipeptides-containing food and drink, and method for producing imidazole dipeptides-rich seafood extract

摘要

PPROBLEM TO BE SOLVED: To provide a method for producing fish and shellfish extract highly containing imidazole dipeptide comprising fish and shellfish as raw material, containing a small amount of arsenic while highly containing the imidazole dipeptide, having low salt content, and less in discoloration. PSOLUTION: The fish and shellfish extract highly containing imidazole dipeptide is obtained through the following process: subjecting extract extracted from fish and shellfish to desalting treatment, passing the obtained desalted treated liquid through slightly acidic ion exchange resin followed by washing the slightly acidic ion exchange resin with water; and eluting the adsorbed substance of the slightly acidic ion exchange resin where the content of the imidazole dipeptide accounts for 5-80 mass% on a solid basis, and the content of an arsenic compound accounts for 150 ppm in a mass ratio based on 1 of the imidazole dipeptide.
