摘要：
The purpose of the present invention is to provide a revolutionary method for sterilizing or inactivating heat-resistant spore-forming bacteria capable of being carried out using simple equipment and providing reliable and sufficient sterilization effects, by reducing the heat resistance of heat resistant spore-forming bacteria due to the effects of a depressurization treatment during a high-pressure treatment, and performing a thermal sterilization treatment after a predetermined rest time has elapsed after the depressurization, to sterilize and inactivate the heat-resistant bacteria with reduced heat resistance. The sterilization or inactivation treatment method for heat-resistant spore-forming bacteria involves, as a pretreatment before a thermal sterilization treatment, subjecting the substance being treated to a high-pressure treatment of applying a hydrostatic pressure of at least 50 MPa and no more than 200 MPa at a temperature of 50 °C or less, then subjecting the substance being treated to a depressurization treatment, and after a predetermined rest time has elapsed since the variation in hydrostatic pressure has occurred due to this depressurization, subjecting the substance being treated, which has been subjected to the depressurization treatment, to a thermal sterilization treatment.
