Sodium Benzoate And Cream Of Tartar

Sodium benzoate is a salt of benzoic acid, a common food preservative. It is produced synthetically. Cream of tartar, also known as potassium bitartrate, is a byproduct of winemaking, typically derived from grapes.

Sodium benzoate is used as a preservative to prevent spoilage from bacteria, mold, and yeast. Cream of tartar acts as a leavening agent in baking, helping baked goods rise, and also stabilizes egg whites. They are often found together in baked goods like cakes, cookies, and snack cakes.

Sodium benzoate is generally recognized as safe (GRAS) by the FDA when used as a preservative. When combined with ascorbic acid (Vitamin C) in beverages, it can form small amounts of benzene, a potential carcinogen; however, levels are typically very low. JECFA and EFSA have evaluated sodium benzoate and established acceptable daily intakes. Cream of tartar is also considered safe for consumption. Evidence on potential behavioral effects in children from artificial food additives, including sodium benzoate, is mixed.
