The Application of Nitrogen in Food Packaging and Grain Storage Industries

Nitrogen, accounting for 78% of the volume of air, is inexhaustible and colorless, non-toxic, and odorless inert gas. At present, it has been widely used in many fields such as food preservation, grain storage, metal heat treatment, petrochemical industry, aerospace technology, glass industry, etc.

Today we will talk about the application and development of nitrogen in the food packaging industry

Food packaging

With the increasing improvement of people's living standards, people's demands for food quality are also increasing. We all hope that every day's food is fresh and delicious, but some food products in the market are always not satisfactory, and the main problem lies in the packaging of food. And nitrogen filled packaged food meets people's needs.

The food packaging bags are filled with nitrogen gas to isolate direct contact between food, fruits, and oxygen in the air, preventing food oxidation, fading, spoilage, and various mold and bacteria from damaging the food. This greatly prolongs the storage cycle of packaged food and ensures its freshness.
