Sodium Citrate (E331) is the sodium salt of citric acid. Like citric acid, it has a sour taste.

Like other salts, it also has a salty taste. 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.

• Commonly used as a sequestrant and pH buffer in food and beverages

• Cold/hot soluble, practically insoluble in ethanol (96%)

• 100% Pure Food Grade Sodium Citrate Powder (E331) for use in spherification and molecular gastronomy.
