Pure nitrogen plays a critical role in ensuring optimal consumer safety for all types of perishable foods. Used for both the transportation and storage of food products, nitrogen allows for efficient, economical preservation, locking in freshness and flavor while safeguarding human health.
Nitrogen is the dominate gas in atmospheric air, but food freshness can be affected by even small amounts of oxygen, which allow harmful microbes, such as bacteria, to flourish. Therefore, nitrogen-rich environments with no more than 2% oxygen by volume are ideal for the processing, packaging, and storing of food products. In fact, nitrogen generation is employed in almost every step of food processing operations.
