Is e941 vegan?

E941 is the European food additive code for nitrogen, an odorless and colorless gas. It is obtained industrially by chilling and compressing atmospheric air, followed by fractional distillation to separate nitrogen from oxygen and other gases. Manufacturers use E941 primarily as a packaging gas and propellant. By displacing oxygen inside sealed food containers, it prevents oxidation, staling, and spoilage without chemically altering the food inside.

This additive is frequently used in modified atmosphere packaging for potato chips, snack foods, ground coffee, nuts, pre-packaged salad greens, and bottled beverages. E941 is vegan because it is sourced entirely from ambient air through mechanical liquefaction and distillation. Its production does not involve any animal raw materials, animal byproducts, or animal-derived processing aids, making it completely suitable for a vegan diet.
