とが知られている。Therefore, in order to improve this defect, JP-A-61-170
As seen in Publication No. 375, the opening of a bag or container containing food is closed with a pressure slightly higher than normal pressure, and the product is sterilized by high-pressure heating in a high-pressure tank, and then the bag or container is placed at normal pressure in the high-pressure tank. The internal steam is discharged using the internal pressure of the container.
It is known to quickly seal the bag or opening and then cool it.

る食品を製造することができる。Effects of the Invention The present invention stores food in a shallow-bottom dish-shaped metal container, sterilizes it by heating in a high-pressure tank, and then inserts an inner lid with degassing holes and heats it with high frequency to remove the air at the top of the metal container along with steam. After removing the air, by sealing the deaeration hole, it is possible to easily package one food product in a high vacuum and simplify the structure and operation of the high pressure tank.Moreover, the inner lid for sealing the metal container is not attached to the high pressure tank. Since it is fitted after the inner lid is heated and sterilized, there is no need to consider the heat resistance of the material that can withstand 135 to 140°C. By accommodating an oxygen agent, it is possible to absorb oxygen and prevent food oxidation, thereby making it possible to produce food that can be stored for a long period of time.
