Effect Of Vacuum Sealer
May 25, 2017

1. The main role of vacuum packaging is to remove oxygen, in order to help prevent food spoilage, its principle is relatively simple, because the spoilage of food is mainly caused by microbial activities, and most microorganisms (such as mold and yeast) survival needs oxygen, and the vacuum packaging is the use of this principle, the packaging bag and food cells in the oxygen pumping out, so that microorganisms lose the environment of survival. Experiments show that when the oxygen concentration in the bag ≤ 1%, the growth and reproduction rate of microorganism drops sharply, and the oxygen concentration ≤ 0.5%, most microorganisms will be inhibited and stop breeding. (Note: Vacuum packaging can not inhibit the reproduction of anaerobic bacteria and enzyme-induced food spoilage and discoloration, and therefore need to be combined with other ancillary methods, such as refrigeration, frozen, dehydration, high-temperature sterilization, irradiation sterilization, microwave sterilization, salt pickling and so on. )


2. In addition to inhibiting the growth and reproduction of microorganisms, the other important function of vacuum oxygen removal is to prevent food oxidation, because the oil food contains a large number of unsaturated fatty acids, by the role of oxygen oxidation, so that food stale, spoilage, in addition, oxidation also makes vitamin A and C loss, food pigments in the unstable substances in the role of oxygen, so that the color dimming. Therefore, the removal of oxygen can effectively prevent food spoilage.


3. Vacuum Inflatable Packaging In addition to the vacuum packaging has the function of oxygen quality, the main also has the pressure, gas, preservation and other functions, can more effectively keep the original food color, fragrance, taste, shape and nutritional value.
