Nitrogen-flushed To Maintain Freshness

Nitrogen is a gas that makes up about 78% of the air we breathe. In food processing, it is often used in its pure form to displace oxygen. This is done by flushing it into food packaging before sealing.

Manufacturers use nitrogen gas to protect foods from spoilage by removing oxygen. Oxygen can cause fats to go rancid and degrade vitamins, leading to off-flavors and reduced nutritional value. It is commonly used in packaging for oils, nuts, coffee, and baked goods to extend shelf life.

Nitrogen gas is generally recognized as safe (GRAS) by the FDA for use in food. It is a natural component of the air and is not absorbed by the body. International bodies like JECFA have evaluated its use and found it to be safe. No health concerns are associated with its use in food.
