Sodium Propionate And Sorbic Acid And Potassium Sorbate

Sodium propionate, sorbic acid, and potassium sorbate are preservatives used to prevent the growth of mold, yeast, and bacteria in foods. Sodium propionate is a salt of propionic acid, which occurs naturally in some foods. Sorbic acid and its salt, potassium sorbate, are synthesized industrially.

These ingredients work together to extend the shelf life of baked goods and other food products by inhibiting microbial spoilage. They are commonly found in cakes, cupcakes, snack cakes, pies, and tortillas, where they help maintain freshness and prevent mold formation.

Sodium propionate, sorbic acid, and potassium sorbate are generally recognized as safe (GRAS) by the FDA for use as food preservatives. Regulatory bodies like JECFA and EFSA have evaluated these substances and found them safe for consumption within typical dietary levels. While generally considered safe, some individuals may experience mild digestive upset, though this is uncommon.
