E939: Helium
Main role: packaging and process gas
Also listed as: He, helium gas
What is E939 (Helium)?
Helium is a gas listed for specified food gas applications. Its role relates to manufacturing or atmosphere management rather than supplying a nutrient or creating a sweet taste.
What does it do in food?
Its main role is packaging and process gas. Gas mixtures are chosen for a particular product and package. A protective atmosphere supports a storage system; it does not replace temperature control, hygiene, or the instructions printed on the pack.
Food and formulation examples
- Specified gas mixtures
- Food-processing atmospheres
- Authorized packaging uses
These examples describe formulation roles, not a list of unrestricted legal uses. Availability and permitted applications differ by country and food category.
Label names and ingredient questions
Look for E939, E 939, or the ingredient name. Related names and label terms include He, helium gas. A family code can cover more than one specified form; check the full declaration when the distinction matters.
A food gas authorization does not cover every novelty use of compressed gas. Use equipment and products intended for the stated application and follow their instructions.
Is E939 safe?
There is no meaningful personal risk estimate from an E number alone. Food-grade specifications, allowed uses, amount consumed, and individual circumstances all matter. The authorization record below gives the legal scope; it is not a claim that every possible use is appropriate.
A label identifies the ingredient but usually not its concentration. Calculating daily intake requires the amount in the food and the quantities eaten.
Authorization and conditions of use
The Great Britain food additive register lists E939 as Helium. This is an entry subject to its stated conditions, not unrestricted permission for every food. The record links to the applicable authorization terms. For an EU product, use the European Commission food additive database to check the relevant food category and limits. Other countries may use different names or rules.
