方法は食品と包装体とを殺菌する他に、製造装置、製造
環境を一定の無菌状態に維持する必要があり、製造コス
トが高いという問題があった。BACKGROUND ART Conventionally, various foods filled in packages have been distributed, but from the viewpoint of hygiene and preservation, it is required that the foods be sterilized. As a method for sterilizing food that is filled and held in a package, there is a method of filling a sterilized package with food that has been sterilized in advance. However, in this method, in addition to sterilizing the food and the package, it is also necessary to maintain the manufacturing equipment and the manufacturing environment in a constant sterile state, resulting in a problem of high manufacturing costs.
これに対して、未殺菌の食品が充填密封された包装体を
そのまま加熱・加圧して殺菌する方法（レトルト殺菌方
法）が開発された。In response, a method (retort sterilization method) has been developed in which a sealed package filled with unsterilized food is sterilized by heating and pressurizing it as it is.
しかしながら、レトルト殺菌方法では包装体が耐熱性を
有することが要求され製造コストが高くなるとともに、
加熱により食品の品質劣化、食感や栄養分の低下を生じ
るという問題があった。However, in the retort sterilization method, the packaging body is required to have heat resistance, which increases manufacturing costs.
There has been a problem in that heating causes deterioration in the quality of food and a decrease in texture and nutritional content.
このような問題を解消するために、近年、高圧により対

い殺菌効果がある。In order to solve these problems, a high-pressure sterilization method has been proposed in recent years, in which objects are sterilized by high pressure (Japanese Patent Laid-Open No. 62-66862, etc.). This high-pressure sterilization method sterilizes objects to be treated by applying high pressure in a pressurized medium, and has a high sterilization effect.
このため、被処理物を高温にする必要がなく被処理物の
品質劣化、食感や栄養分の低下を生じないとともに、製

上させることは可能ではあるが、高圧殺菌装置の大型化
は大幅な設備費の増大をともなうという問題があった。However, it is currently technically difficult to perform high-pressure sterilization continuously, and current high-pressure sterilization equipment has no choice but to adopt a batch processing method, which is less productive than retort sterilization methods. There was a problem. Furthermore, although it is possible to improve productivity by increasing the amount of high-pressure sterilization processed at one time using a batch processing method, there is a problem in that increasing the size of the high-pressure sterilization equipment is accompanied by a significant increase in equipment costs.
本発明は、上記の事情に鑑み創案されたものであり、高
