Modified atmosphere fresh-keeping gas is generally composed of carbon dioxide (CO2), nitrogen (N2), oxygen (O2) and a small amount of special gases. CO2 has the effect of inhibiting the growth and reproduction of most putrefaction bacteria and molds, and is the main bacteriostatic component in the protective gas. O2 can inhibit the growth and reproduction of most anaerobic spoilage bacteria, maintain the color of fresh meat, maintain the aerobic respiration of fresh fruits and vegetables, and maintain their freshness. N2 is an inert gas, which does not work with food. As a filling gas, N2 is composed of composite fresh-keeping gas with CO2, O2 and special gases. The composition and proportion of carbon dioxide (CO2), nitrogen (N2), oxygen (O2) are different for different food.
