What it is

Sodium benzoate is a salt of benzoic acid. It is a white, crystalline powder that is soluble in water. It is produced commercially by reacting sodium hydroxide with benzoic acid.

Why it's used

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

Health notes

In the U.S., sodium benzoate is Generally Recognized As Safe (GRAS) by the FDA when used according to good manufacturing practices. It has been evaluated by JECFA and EFSA. Some studies have explored potential links between sodium benzoate and hyperactivity in children, but the evidence is mixed and not conclusive. When consumed in typical amounts found in food, it is not considered harmful.

Allergen info

Sodium benzoate is not derived from any of the 9 FDA major allergens. It does not contain gluten.
