0.1% Sodium Benzoate As Preservative

Sodium benzoate is a salt of benzoic acid, a chemical that occurs naturally in small amounts in many plants, like cranberries and plums. It is typically made by combining benzoic acid with sodium hydroxide. It appears as a white crystalline powder.

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, so it is often found in acidic foods like salad dressings, carbonated drinks, jams, and pickles.

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. However, the FDA states that the levels of benzene formed are very low and not a safety concern. JECFA and EFSA have evaluated sodium benzoate and established acceptable daily intakes. Some studies have explored links between sodium benzoate and hyperactivity in children, but evidence is mixed and not conclusive.
