Potassium Sorbate And Sorbic Acid And Sodium Propionate

Potassium sorbate, sorbic acid, and sodium propionate are preservatives used to prevent the growth of mold, yeast, and bacteria in foods. Sorbic acid is a naturally occurring compound found in some plants, while potassium sorbate and sodium propionate are synthetic salts. They are typically produced through chemical synthesis.

These ingredients are added to foods to extend shelf life by inhibiting spoilage microorganisms. They are commonly found in baked goods like cakes and pastries, as well as in cheeses, dried fruits, and processed meats. Their function is primarily as a preservative.

Potassium sorbate, sorbic acid, and sodium propionate are generally recognized as safe (GRAS) by the FDA when used as preservatives. International bodies like JECFA and EFSA have also evaluated these substances and found them safe for consumption within typical use levels. While generally considered safe, some individuals may experience mild allergic reactions or sensitivities, though this is rare. Extensive research has not linked them to significant health concerns at the levels found in food.
