It’s the kind of potato just dug out of the ground

without vacuum packaging for 10 days, it can take about 5 months

the main function of vacuum packaging is to remove oxygen to help prevent food deterioration. Its principle is also relatively simple. Because the moldy deterioration of food is mainly caused by the activities of microorganisms, and the survival of most microorganisms (such as molds and yeasts) requires oxygen. Vacuum packaging uses this principle to pump out the oxygen in the packaging bag and food cells, so that microorganisms lose their “living environment”. Experiments show that when the oxygen concentration in the packaging bag is ≤ 1%, the growth and reproduction speed of microorganisms will drop sharply. When the oxygen concentration is ≤ 0.5%, most microorganisms will be inhibited and stop reproduction. (Note: vacuum packaging cannot inhibit the propagation of anaerobic bacteria and the deterioration and discoloration of food caused by enzyme reaction, so it also 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 deaeration is to prevent food oxidation, because fat foods contain a large amount of unsaturated fatty acids, which are affected by The role of oxygen and oxidation, so that food taste and deterioration. In addition, oxidation also causes the loss of vitamin A and vitamin C, and the unstable substances in food pigments are darkened by oxygen. Therefore, deoxidization can effectively prevent food deterioration and maintain its color, aroma, taste and nutritional value.
