It is commonly known as sour salt and is mainly used as a food additive, usually for flavor or as a preservative. It gives club soda both its sour and salty flavors. It reduces the acidity of foods, so it allows spherification with strongly acidic ingredients. Sodium citrate is also used as an antioxidant in food as well as a sequestrant. It dissolves easily and acts instantaneously.
