Suqian vacuum bag, anti-static vacuum bag, the main function of vacuum bag is to remove oxygen to help prevent food deterioration
Its principle is also relatively simple
Because the mildew and deterioration of food is mainly caused by the activities of microorganisms, and most microorganisms (such as molds and yeasts) need oxygen for survival
Vacuum packaging uses this principle to pump out the oxygen in the packaging bag and food cells, so as to lose & ldquo; Living environment & rdquo;
Experiments show that when the oxygen concentration in the packaging bag is ≤ At 1%, the growth and reproduction rate of microorganisms decreased sharply, and the oxygen concentration ≤ At 0
5%, most microorganisms will be inhibited and stop breeding
(Note: vacuum packaging can not inhibit the deterioration and discoloration of food caused by anaerobic bacteria and enzyme reaction, so it needs to be combined with other auxiliary methods, such as cold storage, quick freezing, dehydration, high temperature sterilization, irradiation sterilization, microwave sterilization, salt pickling, etc
) In addition to inhibiting the growth and reproduction of microorganisms, another important function of vacuum deoxidation is to prevent food oxidation
Because fat foods contain a large number of unsaturated fatty acids, they are oxidized by oxygen, which makes the food taste and deteriorate
In addition, oxidation also causes the loss of vitamin A and C, and the unstable substances in food pigments darken the color by oxygen
Therefore, deoxidization can effectively prevent food deterioration and maintain its color, aroma, taste and nutritional value
