E325: Sodium lactate
What is E325?
Sodium lactate is the sodium salt of lactic acid. Labelled E325, it is usually supplied as a clear, slightly salty liquid.
Origin and production
It is produced by fermenting sugars from sources such as maize or sugar beet to make lactic acid, which is then neutralised with sodium hydroxide. It is not derived from milk, despite its name.
Why is it used?
Sodium lactate retains moisture, regulates acidity and helps slow bacterial growth. It extends the shelf life of sausages, cooked meats and sandwiches, and is used in confectionery and gummy sweets to buffer acidity and keep a soft texture.
Vegan, vegetarian and halal
Sodium lactate is made by fermentation of plant sugars and is suitable for vegans and vegetarians; it contains no dairy. It is not generally a halal or kosher concern on its own.
Safety and regulation
Sodium lactate is authorised as a food additive in the EU and may be used at the level needed for its purpose in most permitted foods. Lactate is naturally produced by the human body.
