What is Sodium Citrate?

Sodium citrate is the sodium salt of citric acid, appearing as a white, crystalline, or granular powder that is highly soluble in water. Commonly known as trisodium citrate or "sour salt," it serves as a versatile food additive (E331), functioning as a buffering agent, emulsifier, and preservative in products like processed cheese — enabling a smooth, non-greasy melt — and carbonated drinks. In medical applications, it acts as a critical anticoagulant in blood storage by chelating calcium ions. It is also used to treat metabolic acidosis and prevent kidney stones by raising blood and urine pH. With a slightly sour and salty taste, it is generally recognized as safe (GRAS) by the FDA and commonly used in molecular gastronomy.
