4: Refrigerate at low temperature.  

The principle of low-temperature refrigeration is to use low-temperature environment to reduce the activity of bacteria, so as to inhibit their growth and reproduction;  In actual food preservation, the temperature of about 0℃ or a little higher is often used for refrigeration.  At such temperatures, although it is impossible to completely inhibit the growth of microorganisms, food can be kept in its original state for a considerable time.  Because it is economical, refrigeration is an excellent preservation method for certain types of food.

5: Inflatable packaging. 

Inflatable packaging is commonly found in puffed food such as potato chips and chips, as well as food such as cakes.  Nitrogen or carbon dioxide is usually used as the filling gas.  The idea is that by filling a bag with nitrogen and carbon dioxide, the oxygen level is essentially reduced to zero, which inhibits bacterial growth and reproduction.  Another function of inflatable packaging is to make the bag expand to protect fragile packaging (such as potato chips, chips and so on).

6: External sterilization.  

The external sterilization methods are mainly ultraviolet sterilization and high-temperature cooking sterilization these two ways.  Any living creature is afraid of ultraviolet and high temperature, strong ultraviolet radiation or ultra-high temperature environment can effectively kill the bacteria in the packaging bag;  But it should be noted that ultraviolet sterilization requires that the packaging bag should have good light transmission, And high temperature cooking sterilization requires the packaging bag to have high-temperature cooking performance.
