Overview: Preserving food under a nitrogen blanket is a much better way to extend the shelf life of food exponentially. Consumers are clamoring for high-quality packaging for food and fresh fruit products, but the dangers of chemical preservatives warn against the trend.
In this age of increasing environmental awareness, everyone wants to benefit from naturally chemically inert nitrogen. Nitrogen is a basic environmental substance, a chemically inert, colorless and odorless gas, which accounts for about 79% of the earth's atmosphere. Gaseous nitrogen is used to preserve food without leaving chemical residues.
Molecular Sieve Nitrogen Generator Packaging: Nitrogen is used in the food industry to protect compounds that are susceptible to damage from atmospheric oxygen and moisture. Nitrogen replaces oxygen and moisture in food packaging, reducing food spoilage and air quality loss.
Adverse effects of the atmosphere include mold and bacteria growth, oxidation, discolouration and spoilage. Reducing air in food packaging can prolong the quality and freshness of packaged food, benefiting retailers and consumers. In food packaging, reducing air rather than chemical preservatives has been shown to be another way to extend the life of food.
Nitrogen can be used in nearly every type of fast food packaging, including potato chips, jerky, sliced fresh fruit, vegetables, nuts, biscuits and cookies. To solve moisture problems, very dry nitrogen is used in food packaging. Lowering oxygen levels reduces oxidation and discolouration of food.
