FOOD STERILIZATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a food sterilization method capable of killing highly pressure-resistant sporaceous bacteria universally existing in foods such as Bacillus subtilis to a level of causing no putrefaction to foods under their normal-temperature distribution. SOLUTION: This food sterilization method comprises the preheating step of heating a food (5) to >=50 deg.C and the step of pressurizing thus preheated food (5) under a pressure of >=300 MPa, wherein the food (5) is pressurized in a condition of containing it in a thermally insulated vessel (4).
