<P>PROBLEM TO BE SOLVED: To provide processed foods of fishes and shellfishes hard to be soften or requiring a long time even acting enzymatic reaction with a decomposition enzyme introduced inside by pressure treatment, keeping form, color, scent and nutrient components of the fishes and shellfishes but soft, having good releasability of fish meat from bone and of shellfish meat from the shell, and capable of efficiently produced within a short time; and to provide processed foods which can be eaten by the elderly having difficulty in deglutition and chewing, with recognizing what the foods to be eaten are and with satisfactory. <P>SOLUTION: The processed foods are obtained by passing through a freezing and defrosting step in which unheated fishes and shellfishes are frozen and then defrosted, a pressure treatment step in which the decomposition enzyme contacted on the surface is uniformly contained inside the fishes and shellfishes by pressure treatment, an enzymolysis step in which the enzyme substrate is decomposed by action of the decomposition enzyme, and an enzyme inactivation step in which the decomposition enzyme is deactivated, wherein, the processed foods are obtained by passed through a protein denaturation step before the freezing and defrosting step or immediately after the enzymolysis step, in which protein denaturation step proteins of the unheated fishes and shellfishes are mildly heat-denaturalized in the presence of water. <P>COPYRIGHT: (C)2011,JPO&INPIT |
