Title:
PRODUCTION OF PERTIDE MIXTURE LOW IN PHENYLALANINE CONTENT
Document Type and Number:
Japanese Patent JP3682994
Kind Code:
B2
Abstract:
PURPOSE: To simply produce a high-quality peptide mixture having low and definite phenylalanine content.
CONSTITUTION: The characteristic of this method for producing a peptide mixture having low phenylalanine content and definite quality comprises adding one or two or more kinds of proteolytic enzymes to an aqueous solution of raw material protein or an aqueous solution of a previously lightly hydrolyzed raw material protein, starting hydrolysis of the raw material protein or the previously lightly hydrolyzed raw material protein, timewise measuring an amount of phenylalanine isolated into a decomposed liquid by hydrolysis each in a short time, calculating a ratio of an amount of isolated phenylalanine to the total amount of phenylalanine in a raw material protein or previously lightly hydrolyzed raw material protein, immediately stopping hydrolysis when the calculated value reaches within a previously set specific range and removing isolated phenylalanine in the decomposed liquid. The mixture can widely be utilized as a protein source for meal of infant and adult with phenylketonuria and pregnant woman.
