Sodium Bezoate

Sodium benzoate is the sodium salt of benzoic acid. It is produced when benzoic acid reacts with sodium hydroxide. Benzoic acid is found naturally in many plants, like cranberries and plums, but is often produced synthetically for food use.

Sodium benzoate acts as a preservative by preventing the growth of mold, yeast, and bacteria. It is commonly added to acidic foods and beverages like salad dressings, carbonated drinks, jams, and fruit juices to extend shelf life.

Sodium benzoate is generally recognized as safe (GRAS) by the FDA for use as a food preservative. When combined with ascorbic acid (Vitamin C) in some beverages, it can form small amounts of benzene, a potential carcinogen, though levels are typically very low. JECFA and EFSA have evaluated sodium benzoate and established acceptable daily intakes. Some studies suggest a link between sodium benzoate and hyperactivity in children, but the evidence is mixed and not conclusive.
