STERILIZATION OF FOOD FOR EATING IN RAW STATE, SUCH AS FISH ROE

摘要

PROBLEM TO BE SOLVED: To provide a method for sterilizing a food for eating in a raw state by selectively sterilizing only bacteria adhered to the raw fish roe without denaturing the proteins of the raw fish roe, enabling to eat waste fish roe (separated roe). SOLUTION: This method for sterilizing a food for eating in a raw state comprises mixing fish roe E having bacteria B adhered to the surface with a solution containing a low mol. wt. peptide as a main component under agitation to release the bacteria from the surface of the fish roe E in a floated state, heating the solution at a low temperature H to denature only the proteins of the bacteria B before the denaturation of the proteins of the fish roe E by the utilization of a heat-receiving capacity difference caused by a difference between the sizes of the bacteria B and the fish roe, and immediately cooling the heated solution.
