Oxygen is a major culprit in food spoilage. The most effective way to prevent oxygen damage and package perishable products and is to remove the oxygen and replace it with an inert gas like nitrogen. Replacement of oxygen with nitrogen is simply referred to as nitrogen packaging.
Modifying the composition of the internal atmosphere of a package improves its shelf life. The presence of oxygen allows molds, yeast and aerobic bacteria to survive and degrade perishable products.
When food browns, its components join with oxygen, or oxidize, much as iron does when it rusts. For long term grain and dry goods storage, many people preserve them in mylar bags filled with nitrogen, and seal them inside plastic tubs or metal cans. Similarly, cannabis can be nitrogen packed and sealed for freshness.
Using specialized equipment and packaging, oxygen is replaced with nitrogen so that marijuana stays fresh. We nitro package and heat seal our flowers to prevent oxidation. Nitrogen prevents degradation of perishable products. So your flowers stay fresh. Nitrogen is ideal for use in food packaging as nitrogen is dry, clean and environmentally friendly.
The modification process lowers the amount of oxygen in order to slow down the growth of aerobic organisms and the speed of oxidation reactions. By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. The removed oxygen can be replaced with nitrogen, commonly acknowledged as an inert gas.
Food handlers call this Modified Atmosphere Packaging, a technique used for prolonging the shelf-life of fresh or minimally processed foods. In this preservation technique the air surrounding the food in the package is changed to another composition. Doing so helps prolongs the fresh state of the product. Modified Atmosphere Packaging slows the natural deterioration of the product.
Nitrogen is used widely in the food and beverages industries to enhance packaging and storage of the products Snack foods, including potato chips and peanuts, rely on a source of nitrogen for Modified Atmosphere Packaging. The mixture of gases in the package depends on the type of product being stored, packaging materials and storage temperature.
Benefits of using nitrogen
• Freshness is maintained
• Durability and shelf life are extended
• Environmentally friendly conservation
