Sodium Benzoate To Preserve Freshness

Sodium benzoate is a salt of benzoic acid. It is produced commercially by reacting sodium hydroxide with benzoic acid. Benzoic acid can be synthesized from toluene or derived from natural sources like cranberries, apples, and cinnamon.

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

In the U.S., sodium benzoate is generally recognized as safe (GRAS) by the FDA when used as a food preservative. It has been evaluated by JECFA and EFSA, who have established acceptable daily intakes. Some studies have explored a potential link between sodium benzoate and hyperactivity in children, particularly when combined with artificial food colors, though evidence is mixed and not conclusive.
