Sodium Benzoate And Potassium Metabisulfite

Sodium benzoate is a salt of benzoic acid, a widely used food preservative. It is typically produced industrially by the reaction of sodium hydroxide with benzoic acid. Benzoic acid itself is found naturally in small amounts in many plants, such as cranberries and plums.

Sodium benzoate is primarily used as a preservative to inhibit the growth of bacteria, yeasts, and molds. It is effective in acidic foods and is commonly found in acidic products like fruit juices, carbonated drinks, jams, and pickles. 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. It has been evaluated by JECFA and EFSA, who have established acceptable daily intakes. Some studies have explored potential links between sodium benzoate and hyperactivity in children, particularly when combined with artificial food colors, but the evidence is mixed and not conclusive. Further research is ongoing.
