2, oxygen sensitive food (such as fried peanuts, etc.) packaging atmosphere, vacuum after filling nitrogen can further reduce the residual oxygen content in the package, that is, nitrogen packing, better than vacuum packaging effect.
3, red fresh meat packaging atmosphere, using high oxygen content and carbon dioxide mixture of gas, can keep the color and corrosion.
4, fresh fish packaging atmosphere, the use of O2, CO2 and N2 mixture of gas, can simultaneously inhibit the reproduction of aerobic bacteria and anaerobic bacteria and preservation.
5, fresh fruit and vegetable packaging atmosphere, the use of low oxygen, high carbon dioxide (compared with air) and nitrogen mixture of gas, can inhibit the metabolism of fruit and vegetable aerobic breathing and freshness.
6, cooked food (cooked meat, fried fish, etc.) packaging atmosphere, the use of CO2 and N2 mixture of gas can inhibit the corruption of bacteria and corrosion.
7, baked food (such as cakes, moon cakes, etc.) packaging atmosphere, the use of CO2 and N2 mixture gas can be mildew and anticorrosive.
