E327: Calcium lactate

What is E327?

Calcium lactate (E327) is the calcium salt of lactic acid. It is a white, nearly tasteless powder that dissolves in water and supplies calcium without the chalkiness of some other calcium salts.

Origin and production

It is made by neutralising lactic acid with calcium carbonate or calcium hydroxide. The lactic acid itself is usually produced by bacterial fermentation of plant sugars such as corn or beet, not from milk, despite the similar name.

Why is it used?

Manufacturers use it as a calcium source for fortification, an acidity regulator and a firming agent that helps fruit pieces and vegetables keep their texture. It appears in fortified plant-based drinks, sweetened and aloe vera beverages, and some confectionery.

Vegan, vegetarian and halal

Calcium lactate is normally made without animal ingredients and is generally considered suitable for vegans and vegetarians. Despite the word 'lactate', it does not usually contain lactose or milk protein.

Safety and regulation

E327 is authorised in the EU and has been evaluated by EFSA. It is permitted in many foods at levels set by good manufacturing practice.
