Sodium Benzoate To Protect Flavor

Sodium benzoate is a salt of benzoic acid. It is produced commercially by reacting sodium hydroxide with benzoic acid, which can be made synthetically or derived from natural sources like fruits.

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

In the U.S., sodium benzoate is Generally Recognized As Safe (GRAS) by the FDA when used according to good manufacturing practices. 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 have explored potential links to hyperactivity in children, but evidence is mixed and not conclusive.
