Why can nitrogen be used to prevent corrosion when food is packaged

by admin

the growth of many organisms requires oxygen. After filling nitrogen, the oxygen in the bag can be eliminated, the oxidation can be slowed down, and the oxygen can be reduced. There is no basis for survival. At the same time, N2 is a very inactive substance, and most substances will not react with it at normal temperature and pressure

nitrogen is chemically inactive and difficult to react with other substances at room temperature, so it is often used to make preservatives
most bacteria cannot live without oxygen environment. Food corruption is often caused by bacterial mass reproduction. Due to the chemical inertia of nitrogen, it is often used as a protective gas, such as melons and fruits, food and light bulbs. In order to prevent some objects from being oxidized by oxygen when exposed to the air, fill the granary with nitrogen, and the bacteria can not grow, so that the grain will not mildew and germinate, and can be preserved for a long time.
