Sterilization method for packaging spoon food

Abstract

A method for sterilizing the packed fluid food features that after the packed food is put in a sealed sterilizer, it is heated and pressurized for a certain time and then cooled in the condition that the pressure outside the packing container is always not lower than that inside the packing container. Its advantages are no special requirement to said packing container, and innocuity to food.

Description

Technical field: [0001] The invention relates to the field of food processing, in particular to a sterilization method for packaged liquid food. Background technique: [0002] It is widely used to pack liquid food first and then reheat and sterilize it. However, during the heating and cooling process, the pressure inside the package is often higher than the pressure outside the package, so the package is easily burst by the pressure inside the package. If glass bottles are used for packaging, accidents of explosion and wounding often occur, so the prior art cannot use common packaging, which has special requirements for the compressive strength of the packaging. Invention content: [0003] The object of the present invention is to provide a sterilization method for packaged liquid food with low sterilization cost, common packaging without cracking, no antiseptic and sterilizing agent in the food, and long shelf life. [0004] The sterilization method for packaged liquid f...

[0002] It is widely used to package liquid food first and then reheat and sterilize it. However, during the heating and cooling process, the pressure inside the package is often higher than the pressure outside the package, so the package is easily burst by the pressure inside the package.

If glass bottles are used as packaging, accidents of explosion and injury often occur. For this reason, ordinary packaging cannot be used in the prior art, and it has special requirements for the compressive strength of the packaging.
