Analysis Of Vacuum Packaging Machinery Market In China

Vacuum packaging of main role is except oxygen, to conducive to prevent food metamorphic, its principle also compared simple, for food mold rot metamorphic main by microbial of activities caused, and most microbial (as mold and yeast) of survival is need oxygen of, and vacuum packaging is using this principle, put packaging bags within and food cell within of oxygen pumping off, makes microbial lost survival of environment.


Vacuum packaging of main role is except oxygen, to conducive to prevent food metamorphic, its principle also compared simple, for food mold rot metamorphic main by microbial of activities caused, and most microbial (as mold and yeast) of survival is need oxygen of, and vacuum packaging is using this principle, put packaging bags within and food cell within of oxygen pumping off, makes microbial lost survival of environment.


The vacuum oxygen removal in addition to inhibiting the growth and reproduction of microorganisms, but another important function is to prevent the oxidation of food because oil contains unsaturated fatty acids in food, oxygen and oxidation, making food taste, deterioration. Also under pressure, choke, fresh and so on, can make food more efficiently keep the original color, aroma, taste and appearance and nutritional value.


Purchase, packaging solid, granular, dry and non-corrosive materials, aluminum alloy materials, and packed soup, salt and acid composition of materials, you can use stainless steel or aluminum-magnesium alloy materials. Seal using silicone rubber, black rubber, a few low quality products with foam rubber, silicone rubber high temperature resistance, corrosion resistance, good seal, have long performance life, foam rubber bad seal, easily pulled off, short life.
