Potassium Sorbate To Retard Mold

Potassium sorbate is the potassium salt of sorbic acid. Sorbic acid is a naturally occurring compound found in some plants, but for food use, it is typically produced synthetically. It is a white crystalline powder that is soluble in water.

Potassium sorbate is used as a food preservative to inhibit the growth of mold, yeast, and some bacteria. This helps to extend the shelf life of foods. It is commonly found in products like cheese, baked goods, dried fruits, and beverages.

In the U.S., potassium sorbate is generally recognized as safe (GRAS) by the FDA when used as a food additive. International bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have also evaluated potassium sorbate. While generally considered safe, some individuals may experience mild allergic reactions or sensitivities, such as skin rashes or digestive upset, though these are rare.
