What is the purity of the nitrogen provided by the food preservation nitrogen generator for food packaging, and what direct impact does this have on the quality of food packaging?

Food preservation nitrogen generators for food packaging are of great significance for improving the overall quality of food packaging and extending the shelf life of food. High-purity nitrogen creates a low-oxygen or even anaerobic environment by displacing oxygen within the package, which is lethal to most aerobic microorganisms. In such an environment, the growth and reproduction of microorganisms are severely inhibited, effectively extending the shelf life of food. Especially for perishable foods, such as meat, dairy products, fruits and vegetables, the use of high-purity nitrogen can significantly slow down the spoilage process.
Oxygen is the main catalyst for oxidative deterioration of food, which can lead to fat oxidation, protein denaturation, loss of vitamins and pigments, etc. High-purity nitrogen effectively blocks these adverse oxidation reactions by completely eliminating oxygen in the packaging, protecting the original flavor, color and nutritional value of the food.
For some foods that are extremely sensitive to oxygen, such as potato chips, nuts, biscuits, etc., high-purity nitrogen filling can prevent them from becoming soft or losing their crispness due to oxidation. At the same time, for meat and fish products, nitrogen can also prevent odor and color changes caused by fat oxidation, maintaining the freshness and attractive appearance of the food.
High-purity nitrogen filling reduces gas residues and impurities in the packaging, allowing the packaging material to better fit the food and improve the sealing performance of the packaging. This not only prevents the intrusion of external air and microorganisms, but also reduces pressure changes inside the package and enhances the integrity and stability of the package.
Nitrogen, as an inert gas, has excellent buffering properties. During the packaging process, it can effectively protect food from physical damage, such as extrusion, collision, etc. This is critical to maintaining the shape, structure and integrity of food products, especially during long-distance transportation and warehousing.
High-purity nitrogen effectively reduces the risk of food poisoning by creating an environment unfavorable for microbial survival. This is of great significance for improving the overall safety of food and consumer trust. Nitrogen is a non-toxic, odorless, colorless gas that does not react chemically with food or produce harmful substances. Therefore, using high-purity nitrogen for food packaging can ensure the purity and safety of food.
