Potassium Sorbate & Sodium Benzoate

Potassium sorbate and sodium benzoate are salts of sorbic acid and benzoic acid, respectively. They are often used together as preservatives. They can be produced synthetically or derived from natural sources like rowan berries (for sorbic acid) and cranberries (for benzoic acid).

These compounds are added to foods to prevent the growth of mold, yeast, and bacteria, thus extending shelf life. They are commonly found in acidic foods such as salad dressings, carbonated drinks, jams, jellies, and pickles.

Potassium sorbate and sodium benzoate are generally recognized as safe (GRAS) by the FDA when used according to good manufacturing practices. Both have been evaluated by JECFA and EFSA. Some studies suggest a potential link between sodium benzoate and hyperactivity in children, but evidence is mixed and regulatory bodies have not established a causal link at typical intake levels. They are not known to cause adverse health effects at the levels typically found in food.
