Application principle of food vacuum bag
The main function of food vacuum bag is to remove oxygen, which is conducive to prevent food deterioration. Its principle is relatively simple. Because food moldy rot is mainly caused by the flow of microorganisms, and most microorganisms (such as molds and yeasts) need oxygen for survival. Vacuum packaging is based on this principle to pump oxygen out of the packaging bag and food cells, so that microorganisms lose their life The living environment.
The results show that when the oxygen concentration in the bag is less than or equal to 1%, the growth and reproduction speed of microorganisms will drop sharply. When the oxygen concentration is less than 0.5%, most microorganisms will be restrained and stop breeding.
In addition to inhibiting the growth and reproduction of microorganisms, another important function of vacuum deoxidization is to prevent food oxidation. Oil food contains a large number of unsaturated fatty acids, which are oxidized by oxygen, which makes food taste and deterioration. In addition, oxidation also causes the loss of vitamin A and C, and the non disordered substances in food pigments are affected by oxygen, making the color dark. Therefore, deoxidization can effectively prevent food deterioration.
