Consumer Advice

Sodium citrate is the sodium salt of citric acid and one of the most common acidity regulators. It also acts as a buffer, emulsifying salt and antioxidant enhancer in drinks, jellies, cheese, jams and convenience foods, adjusting tartness and stabilising texture. It is a normal metabolic substance and very safe at authorised levels; those on low-sodium diets should simply count its sodium.
