Application of Nitrogen Generator in Food Packaging and Processing Field

Overview: Covering food with nitrogen is a good method for preserving food, as it can double the shelf life of food.

Consumers are clamoring for high-quality packaged food and fresh fruit products, but the dangers of chemical preservatives warn against this trend. In this era of increasing environmental awareness, everyone hopes to benefit from natural and chemically inert nitrogen gas.

Nitrogen is a fundamental environmental substance, which is a chemically inert, colorless, and odorless gas that accounts for approximately 79% of the Earth's atmosphere. Gaseous nitrogen does not leave chemical residues when used to preserve food.

Packaging: Nitrogen is used in the food industry to protect compounds that are susceptible to damage from oxygen and moisture in the atmosphere. Replacing oxygen and moisture in food packaging with nitrogen can reduce food spoilage and quality loss caused by air pollution.

The adverse effects of the atmosphere include the growth, oxidation, fading, and decay of mold and bacteria. Reducing air in food packaging can prolong the quality and freshness of packaged food, which is beneficial for both retailers and consumers.

The method of reducing air in food packaging instead of using chemical preservatives has been proven to be another way to extend the lifespan of food. Almost every type of fast food packaging can use nitrogen, including potato chips, jerky, fresh fruit slices, vegetables, nuts, cookies, and cookies. The use of very dry nitrogen in food packaging is to solve the problem of moisture. Reducing the oxygen content can lower the oxidation and fading of food.
