Food processing: During critical processes like mixing, coating and grinding, nitrogen is a key ingredient. In mixing, nitrogen can help cool products after the cooking process to prepare them for packaging sooner. Liquid nitrogen's cooling capabilities also make it easy to coat individually quick-frozen products in sauces as they freeze. In grinding, nitrogen helps reduce frictional heat to improve throughput and prevent the loss of flavor in the foods being processed.
Food preservation and vacuum packaging: Naturally preserving food products with nitrogen helps to extend shelf life. Nitrogen displaces oxygen and moisture efficiently by using a process referred to as modified atmosphere packaging (MAP). MAP is particularly valuable for dairy products and high-fat snack foods. In some cases, a little bit of oxygen is needed inside the packaging to maintain the product's color, like red meat. However, nitrogen will still be the bulk of the gas inside the package.
Food storage: As with packaging, nitrogen is used in storage to preserve food products. Food and beverage operations often have bulk goods in storage to help manufacture products for the shelves. Nitrogen protects these investments and prevents them from spoiling so that they're safe for consumption. Using nitrogen in storage can also ward off pests.
