Sodium Diacetate And Sodium Benzoate

Sodium diacetate is a compound made from acetic acid (vinegar) and sodium acetate. It is a white crystalline powder that dissolves in water. Sodium benzoate is a salt of benzoic acid, often produced by reacting sodium hydroxide with benzoic acid.

This combination is often used as a preservative and to control acidity in baked goods like cakes and snack cakes. It helps prevent spoilage by inhibiting the growth of mold and bacteria, extending the shelf life of products.

Sodium diacetate and sodium benzoate are both permitted food additives in the U.S. The FDA lists sodium diacetate as GRAS (Generally Recognized As Safe) for use as a flavoring agent and preservative. Sodium benzoate is also permitted by the FDA as a preservative. JECFA (the Joint FAO/WHO Expert Committee on Food Additives) has evaluated both substances. While generally considered safe at typical levels, some studies have explored potential links between sodium benzoate and hyperactivity in children, though evidence is mixed and not conclusive. The FDA monitors scientific literature for safety concerns.
