Background technique

The modified atmosphere preservation technology generally refers to a technique for prolonging the storage life of a food by adjusting the gas atmosphere (gas composition ratio or gas pressure) of the enclosed space in which the storage is located, and the basic principle is: in a certain closed space. A gas atmosphere different from the normal air component is obtained by various adjustment methods to suppress physiological and biochemical processes and microbial activities leading to spoilage of the stored matter (usually the foodstuff). In particular, in the present application, the modified atmosphere preservation will be specifically directed to a modified atmosphere preservation technique that adjusts the proportion of gas components.

It is known to those skilled in the art that normal air components include (by volume percent, hereinafter the same): about 78% nitrogen, about 21% oxygen, about 0.939% rare gas 0.031% carbon dioxide, and 0.03% other gases. And impurities (for example, ozone, nitrogen monoxide, nitrogen dioxide, water vapor, etc.. In the field of modified atmosphere preservation, it is common to use a nitrogen-filled space to reduce the oxygen content in a closed space to obtain a nitrogen-rich and oxygen-poor fresh gas. Atmosphere. Here, those skilled in the art are aware that a nitrogen-enriched gas refers to a gas having a nitrogen content exceeding the nitrogen content of the above-mentioned normal air, for example, the nitrogen content thereof may be 95% to 99% or even higher; and the nitrogen-rich oxygen is rich. The fresh gas atmosphere refers to a gas atmosphere in which the nitrogen content exceeds the above-mentioned normal air nitrogen content and the oxygen content is lower than the oxygen content in the above-mentioned normal air.

The history of modified atmosphere preservation technology dates back to 1821 when German biologists discovered that fruits and vegetables could reduce metabolism at low oxygen levels.
