Sodium Benzoate Less Than 0.1% As A Food Preservative

Sodium benzoate is a salt of benzoic acid, a compound that occurs naturally in some fruits like cranberries and apples. It is typically manufactured synthetically from toluene. It is commonly used as a preservative in foods and beverages.

Manufacturers add sodium benzoate to foods and beverages to prevent the growth of mold, yeast, and bacteria, thereby extending shelf life. It is particularly effective in acidic foods and is often found in soft drinks, fruit juices, jams, and condiments.

Sodium benzoate is generally recognized as safe (GRAS) by the FDA when used as a food preservative. JECFA and EFSA have evaluated sodium benzoate and established acceptable daily intakes. In combination with ascorbic acid (Vitamin C) and under certain conditions like heat or light exposure, it can form small amounts of benzene, a known carcinogen. However, levels of benzene formed are typically very low and below limits set for drinking water.
