Potassium Sorbate And Sodium Benzoate To Protect Flavor

Potassium sorbate and sodium benzoate are salts of sorbic acid and benzoic acid, respectively. Sorbic acid is found naturally in some plants, like rowan berries. Benzoic acid is found in many plants, including cranberries and cinnamon. Both are typically produced synthetically for use in food.

These compounds are added to foods as preservatives to inhibit the growth of mold, yeast, and bacteria, helping to extend shelf life and protect flavor. They are commonly found in acidic foods like pickles, olives, relishes, deli salads, and beverages.

Potassium sorbate and sodium benzoate are both approved for use in food in the U.S. and are generally recognized as safe (GRAS) by the FDA. Regulatory bodies like JECFA and EFSA have evaluated these preservatives and established acceptable daily intake levels. While generally considered safe at typical consumption levels, some studies have explored potential links to hyperactivity in children, though evidence is mixed and not conclusive.
