Food preservation gas is widely used in food packaging technology today. Has the effect of increasing the shelf life of the product. Did you know nitrogen gas is one of the best food preservation gases? Let's find out how to preserve food in Nitrogen packaging with Venmer.

1/ Nitrogen gas, Preserving food with nitrogen

Nitrogen makes up 78% of the atmosphere's volume. This is a colorless, odorless, insoluble gas. Non-toxic to the environment and humans under normal conditions. Does not react chemically with most substances, is a chemically inert gas. Those are also the advantages that make nitrogen widely used in the food industry. Under atmospheric pressure nitrogen gas liquefies at a temperature of -196°C.

Gas packaging for food preservation is a technique used to extend the shelf life of food. The main characteristic of modified atmosphere packaging is after packaging with suitable absorbent material. The air around the food will be replaced with the necessary gas. To actively regulate the gas environment during meat preservation. Inhibits the growth and reproduction of microorganisms, inhibits oxidation of fats and slows down discoloration. The mix of gases in the package depends on the product type, packaging material and storage temperature.

3/ Preserving food in packaging with nitrogen gas

Nitrogen is used as a gas supplement. Because it inhibits the growth of bacteria and it prevents Oxidation. Oxidation is caused by the presence of Oxygen in packaged snacks and dry products. Therefore, people seek to increase the amount of nitrogen and reduce the amount of oxygen in the gas composition. Preservation of food with nitrogen
