What is it?
nitrogen (INS 941) is a Foaming agent, Packaging gas, Propellant food additive. Used to generate or stabilise foam, improving texture and mouthfeel.Used to displace air in packages to preserve, prevent oxidation or inhibit microbes.Used in aerosol packaging to expel food (e.g. cream).
Source
Natural：E.g. soy protein, lecithin, gelatin.Gas mixtures of nitrogen, carbon dioxide, oxygen.Food-grade gases such as nitrous oxide, carbon dioxide, nitrogen.
Industrial：Purified or modified.Purified and filled.Purified and compressed.
