What it is
Nitrogen is a colorless, odorless gas that makes up about 78% of the air we breathe. It is a natural element found throughout the environment, including in soil, water, and living organisms. In food processing, it is often used in its pure, gaseous form.
Why it's used
Nitrogen gas is commonly used to displace oxygen in food packaging, a process called "Modified Atmosphere Packaging" (MAP). This helps to preserve freshness, prevent spoilage, and maintain the color and texture of foods like baked goods, meats, and snacks. It can also be used as a propellant in aerosol cans for products like whipped cream.
Health notes
Nitrogen gas is generally recognized as safe (GRAS) by the FDA for use in food. It is an inert gas and does not react with food components. International bodies like JECFA have evaluated nitrogen and found it safe for consumption. There are no known adverse health effects associated with consuming foods packaged with nitrogen gas at typical levels.
Allergen info
Nitrogen is not derived from any of the nine FDA major allergens. It is also gluten-free.
