In the vacuum state of packaging things, the growth of votular microorganisms is slowed or suppressed, reducing protein degradation and fat oxide, and can effectively prevent food from rotting and storing food. In addition, after vacuum packaging, the proliferation of lactic acid bacteria and ligament is reduced to 5.6 to 5.8, which further inhibited the growth of other bacteria, thereby extending the storage period of the product. Vacuum packaging generally needs to combine other commonly used anticorrosive methods to achieve good preservation effects, such as dehydration, adding spice, sterilization, frozen, etc.
