Benzoate Of Soda And Sodium Bisulfite

Benzoate of soda, also known as sodium benzoate, is a salt of benzoic acid. It is produced industrially by reacting sodium hydroxide with benzoic acid. Benzoic acid is found naturally in many plants, like cranberries and cinnamon.

Sodium benzoate is a preservative that helps prevent the growth of mold, yeast, and bacteria. It is often used in acidic foods and drinks, such as pickles, olives, relishes, salad dressings, and carbonated beverages. It helps extend the shelf life of these products.

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 health concern. JECFA has evaluated sodium benzoate and set an acceptable daily intake. Some studies have explored potential links between sodium benzoate and hyperactivity in children, but evidence is mixed and not conclusive.
