Sodium Benzoate Perservative

Sodium benzoate is a salt of benzoic acid, a chemical that occurs naturally in some fruits and spices. It is typically manufactured by reacting sodium hydroxide with benzoic acid. It appears as a white crystalline powder.

Sodium benzoate is widely used as a preservative in acidic foods and beverages to prevent the growth of mold, yeast, and bacteria. It is effective at inhibiting spoilage and extending shelf life. It is commonly found in foods like pickles, olives, relishes, jams, fruit juices, and carbonated drinks.

Sodium benzoate is generally recognized as safe (GRAS) by the FDA when used as a food preservative. It has been evaluated by international bodies like JECFA and EFSA. While generally considered safe at typical consumption levels, some studies have explored potential links between sodium benzoate and hyperactivity in children, though evidence is mixed and not conclusive. When combined with ascorbic acid (Vitamin C) in certain beverages, it can form small amounts of benzene, a known carcinogen, especially when exposed to heat or light; however, levels are typically very low and below limits set for drinking water.
