Nitrogen

Group: Other

Harm level1 of 5No concern

In plain words

Nitrogen is a colourless, tasteless and odourless gas that makes up most of the air you breathe. It replaces oxygen in packaging to keep foods such as crisps, nuts or bagged salads fresh for longer.

Where you find it: crisps, bagged salads, coffee

Our recommendation

No need to avoid.

Possible risks and effects

  • No relevant risk known at normal intake.

For experts

Nitrogen (N₂) is an inert gas used as a packaging gas in modified-atmosphere packaging, limiting oxidation and the growth of aerobic microorganisms. It is also used for freezing and in drinks (e.g. nitro beer or coffee). It is authorised in the EU at quantum satis and poses no toxicological risk.
