Azot oksit

Detailed information

What it is & how it is made

Nitrous oxide, also known as dinitrogen monoxide, is a colourless, non-flammable gas with a sweetish odour. The EU specification requires at least 99 per cent purity.

Where it is used

It is used as a propellant. In pressurised whipped cream it dissolves in the cream and expands on release, increasing volume and creating the foam texture.

Health note

The amount consumed with food is very small and no health risk has been reported for that use. Inhaling the pure gas, however, is not a food use and can cause serious harm to the nervous system and to vitamin B12 metabolism.

Halal assessment

It is a gas obtained from air or by synthesis, produced without animal raw materials and not permanently incorporated into the food. No halal concern has been reported.
