Nitrogen can help extend the shelf life of certain foods by reducing oxygen exposure, which can slow oxidation and help maintain product quality. The actual shelf-life improvement depends on the food product, packaging material and storage conditions.
Nitrogen flushing can help reduce oxygen inside food packages, minimize oxidation and protect product quality. It can also help maintain the desired package atmosphere during storage and transportation.
Yes, nitrogen is widely used in food packaging when it meets the required food-grade specifications and is used according to applicable food-safety requirements. The gas quality and packaging process should be appropriate for the specific food application.
The required nitrogen purity depends on the food product, packaging process and applicable food-safety requirements. Food manufacturers should specify nitrogen quality based on the application rather than using a single purity level for every product.
A nitrogen generator separates nitrogen from compressed air and supplies it on-site for food-processing or packaging applications. PSA and membrane technologies can be used, with the appropriate system selected according to required purity, flow rate and operating conditions.
Nitrogen is commonly used for products such as snack foods, chips, nuts, coffee, bakery products, cereals and other foods where reducing oxygen exposure can help maintain product quality. The suitability depends on the specific product and packaging process.
Nitrogen packaging can help slow certain forms of food deterioration by reducing oxygen exposure, but it does not prevent all types of spoilage. Product formulation, packaging integrity, temperature, humidity and hygiene also play important roles in food shelf life.
The cost of a nitrogen generator varies according to required nitrogen purity, flow rate, pressure, technology, installation requirements and plant capacity. A site-specific assessment is needed to determine the appropriate system and total installation cost.
On-site nitrogen generation can provide a continuous nitrogen supply at the packaging facility and reduce dependence on cylinders or bulk-gas deliveries. It can also help simplify gas logistics and provide nitrogen according to the plant’s required flow and purity.
