Preparation of amino acid components by enzymatic degradation of roe skin

摘要

PROBLEM TO BE SOLVED: To collect peptides and amino acids from fish egg shells which are produced when egg particles of various kinds of fishes are utilized, by enzymatically degrading constitutional proteins of the shells, and to make efficient use of the same.;SOLUTION: A method for producing the amino acids and the peptides useful as enrichments for food products, or the like, from the fish egg shells comprises treating the fish egg shells which have been washed by cold water with ozone water of a temperature lower than room temperature, then degrading the shells with a protease produced by a bacillus (Bacillus subtilis), and further preferably treating the degraded shells with another protease produced by a fungi (Aspergillus oryzae) so as to degrade a fibrillary protein (contractile protein: myosin) in the fish egg shells and to form a degraded liquid, and finally concentrating/drying the degraded liquid.;COPYRIGHT: (C)2004,JPO
