Potassium Sorbate And Sodium Benzoate To Preserve Freshness

Potassium sorbate and sodium benzoate are salts of sorbic acid and benzoic acid, respectively. They are commonly produced synthetically through chemical processes. These compounds are frequently used together in foods because they work well in a wider pH range than either compound alone.

Potassium sorbate and sodium benzoate are used as antimicrobial preservatives to inhibit the growth of mold, yeast, and bacteria. They help extend the shelf life of many processed foods by preventing spoilage. You can find them in products like dairy products, baked goods, beverages, jams, and deli salads.

Potassium sorbate and sodium benzoate are generally recognized as safe (GRAS) by the FDA when used for their intended purpose. Both have been evaluated by JECFA and EFSA. Some studies suggest potential links between sodium benzoate and hyperactivity in children, but evidence is mixed and regulatory bodies have not established specific upper limits for intake from food. In combination, they are considered safe at typical consumption levels.
