Potassium Sorbate & Sodium Benzoate To Maintain Freshness

Potassium sorbate and sodium benzoate are salts of sorbic acid and benzoic acid, respectively. They are often used together because they work best at different pH levels. They are manufactured synthetically.

These ingredients are effective preservatives that prevent the growth of mold, yeast, and bacteria. They help maintain the freshness and safety of many foods and beverages, especially those with a lower pH, like fruit juices, sodas, and salad dressings.

Potassium sorbate and sodium benzoate are permitted food additives in the U.S. and are generally recognized as safe (GRAS) by the FDA when used according to regulations. Both have been evaluated by international bodies like JECFA and EFSA. Some studies have explored potential links between sodium benzoate and hyperactivity in children, though the evidence is mixed and not conclusive. Concerns have also been raised about the formation of benzene when sodium benzoate is combined with ascorbic acid (Vitamin C) under certain conditions, though levels are generally considered safe.
