vacuum packaging refers to removing the air in the packaging bag and sealing to isolate the food in the packaging bag from the outside world. In the vacuum state, the growth of aerobic microorganisms slows down or is inhibited, which reduces the degradation of protein and the oxidative rancidity of fat. In addition, after vacuum packaging, lactic acid bacteria and anaerobic bacteria proliferate, and the pH is reduced to 5.6 ~ 5.8, which further inhibits the growth of other bacteria and prolongs the storage period of the product. Vacuum packaging generally needs to be combined with other commonly used anti-corrosion methods to achieve good preservation effect, such as dehydration, adding spices, sterilization, freezing and so on

At present, there are vacuum packaging in plastic bags, aluminum foil packaging, glassware, plastic and composite packaging, etc.
