E262: Sodium acetate

What is E262?

Sodium acetate (E262i) is the sodium salt of acetic acid, the acid that gives vinegar its sharpness. It is a white powder with a mild vinegar-like, salty taste.

Origin and production

It is made by neutralising acetic acid with sodium hydroxide or sodium carbonate. The acetic acid may be synthetic or produced by fermentation.

Why is it used?

It acts as a preservative and acidity regulator, helping to limit the growth of spoilage and pathogenic bacteria in sausages, cooked and cured meats and smoked lardons. It also contributes a tangy, salt-and-vinegar flavour to some snacks.

Vegan, vegetarian and halal

Sodium acetate is produced without animal ingredients and is generally suitable for vegans and vegetarians, although it often appears in meat products.

Safety and regulation

Sodium acetates are authorised in the EU for general use and have been evaluated by EFSA. Acetate is also a normal product of human metabolism.
