Is the nitrogen in modified atmosphere packaging harmful to the human body?

Modified atmosphere packaging generally uses inert gases such as nitrogen and carbon dioxide to inhibit bacteria and preserve food. Is the nitrogen in modified atmosphere packaging harmful to the human body? The answer is no. The nitrogen in modified atmosphere packaging is harmless to the human body.

Because only when people are in an environment with a high concentration of nitrogen, direct inhalation of nitrogen will have an impact on the human body, causing people to become excited, shout and scream, and finally cause coma and other hazards. However, the nitrogen in Food Packaging is only a certain amount of nitrogen filled in the packaging box, which will not put people directly in a high nitrogen environment, and nitrogen will not react chemically with food and will not be absorbed by food, so it will not be harmful to the human body when used.

However, it should be noted that the purity and quality of nitrogen in food modified atmosphere packaging must be paid attention to. The nitrogen in modified atmosphere packaging is separated from compressed air by membrane separation or pressure swing adsorption. The purity of nitrogen separated by this method can reach more than 99.9%, and the nitrogen used in food modified atmosphere packaging is pure nitrogen grade.
