Sodium Benzoate Less Than 1/10 Of 1% As Food Preservative

Sodium benzoate is a salt of benzoic acid. It is produced when benzoic acid reacts with sodium hydroxide. Benzoic acid is found naturally in small amounts in many plants, such as cranberries and plums, but is typically manufactured for food use.

Sodium benzoate is used as a preservative to prevent the growth of mold, yeast, and bacteria in foods and drinks. It is most effective in acidic conditions. It is commonly found in acidic foods like salad dressings, carbonated drinks, jams, and fruit juices.

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 generally very low. JECFA (Joint FAO/WHO Expert Committee on Food Additives) has evaluated sodium benzoate and established an acceptable daily intake. EFSA (European Food Safety Authority) has also evaluated it.
