Sodium Benzoate And Citric Acid

Sodium benzoate is a salt of benzoic acid, a chemical that occurs naturally in some fruits. It is typically manufactured synthetically. Citric acid is a weak organic acid found naturally in citrus fruits, but is most often produced commercially through the fermentation of sugar by mold.

Sodium benzoate and citric acid are often used together as a preservative and acidity regulator. They help prevent spoilage by inhibiting the growth of mold, yeast, and bacteria. They are commonly found in acidic foods and beverages like soft drinks, jams, fruit juices, and salad dressings.

Sodium benzoate is Generally Recognized As Safe (GRAS) by the FDA when used according to good manufacturing practices. Citric acid is also GRAS. Both have been evaluated by 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 beverages, sodium benzoate can form small amounts of benzene, a known carcinogen, under certain conditions like heat and light exposure; however, levels are typically very low.
