A method for producing a peptide having excellent water solubility from a protein having insoluble and gelling properties

摘要

The present invention has been conceived in order to solve the above problems in the process for producing industrially useful peptides from proteins, and industrially useful peptides can be obtained with high efficiency and high yield without risk of toxic substances in the process, And a protein having gelation properties. The purpose of the present invention is to provide a novel paphed preparation process in which 5 to 20% protein water dispersion is mixed with an acid solution of 0.1 to 0.5N at 90 to 100C for 30 minutes to 2 Followed by a time treatment, followed by an alkaline enzyme treatment followed by a flabotine enzyme treatment.
