Consumer Advice
Argon is a colourless, odourless inert gas used as a packaging gas in food. It is pumped into packages to displace oxygen, preventing oxidation and extending shelf life, and is commonly used for crisps, nuts and coffee. It does not react with food or get absorbed by the body, so it has no effect on health and is recognised as a safe food gas.
