<P>PROBLEM TO BE SOLVED: To provide a method for softening fish bones using microwave irradiation to produce a product having brittle (softened) fish bones. <P>SOLUTION: The method for softening fish bones using microwave irradiation includes irradiating microwaves to frozen fish meat with bones in a temperature range where the specific dielectric loss ratio of the fish bone is higher than that of fish meat. Fish meat with bones is produced by internally heating only the fish bones obtained by the method. The microwaves to be irradiated comprise pulse waves. The microwaves are irradiated to the frozen fish meat with bones using a coolant having a small specific dielectric loss ratio while cooling the fish meat. The temperature of the fish meat after irradiation with the microwaves is -20°C to 130°C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
