What food-grade means in practice
A marketing phrase or cylinder colour is not enough to establish suitability. The product should be labelled for food use and supplied with information that allows a business to identify the manufacturer or responsible supplier, batch and intended application.
Kitchen teams should keep this evidence with their food-safety records and ensure the gas-contact equipment is also suitable for food use.

Frequently asked questions
What does E942 mean?
E942 is the food-additive identifier for nitrous oxide in authorised food applications.
Is every nitrous oxide cylinder food-grade?
No. Use only a clearly identified product supplied for food use with appropriate documentation.
Does food-grade mean it is safe to inhale?
No. Food-grade describes an authorised food-processing use; it does not make recreational inhalation lawful or safe.
What records should a food business keep?
Keep supplier, product, batch, invoice and relevant safety or food-use documentation according to the business food-safety system.
