E939 – Helium
StabiliserDescription
An inert, colorless, odorless, non-toxic, non-flammable noble gas (He) used primarily as a propellant and protective packaging gas in modified atmosphere packaging (MAP). It displaces oxygen and moisture to inhibit spoilage reactions, acting as a functional processing aid.
Notes
Helium is the second most abundant element in the universe and the second-lightest element after hydrogen. On Earth, it's extracted from natural gas deposits where it has accumulated over millions of years from radioactive decay of uranium and thorium in rocks. The extraction process involves separating helium from natural gas through cooling and pressure techniques. Helium is completely colorless, odorless, non-toxic, and chemically inert, meaning it won't react with anything. In the food industry, helium is used as a propellant in pressurized dispensers and as a packaging gas to create protective atmospheres around sensitive foods. Its light weight and inert properties make it ideal for whipped cream dispensers, aerosol cooking sprays, and some specialty food packaging where preventing oxidation is crucial. You might encounter it in premium packaged foods, particularly those where maintaining texture and preventing rancidity are important. Helium is completely natural and safe for all dietary preferences and restrictions. It's suitable for vegetarian, vegan, kosher, and halal diets without any concerns. Like argon, helium is chemically inert and doesn't interact with food, making it extremely safe according to all food safety authorities. Any helium that comes into contact with food simply dissipates harmlessly into the air when packages are opened, similar to how helium balloons gradually deflate.
