What it is

Sodium benzoate is the sodium salt of benzoic acid. It is a white, crystalline powder that is soluble in water. It is produced commercially by reacting benzoic acid with sodium hydroxide or sodium carbonate.

Why it's used

Sodium benzoate is used as a preservative in many processed foods and beverages. It is effective at inhibiting the growth of bacteria, yeast, and mold, especially in acidic conditions. It is commonly found in acidic foods like soft drinks, fruit juices, jams, pickles, and salad dressings.

Health notes

In the U.S., sodium benzoate is generally recognized as safe (GRAS) by the FDA when used as a food preservative. When combined with ascorbic acid (Vitamin C) in some beverages, it can form small amounts of benzene, a potential carcinogen. However, levels are typically very low and below limits set for drinking water. JECFA and EFSA have also 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.

Allergen info

Sodium benzoate is not derived from any of the nine FDA major allergens. It does not contain gluten.
