A Food Preservative At 1/10 Of 1

Potassium sorbate is the potassium salt of sorbic acid. It is a manufactured chemical, often appearing as a white crystalline powder. It is produced by neutralizing sorbic acid with potassium hydroxide.

Potassium sorbate is used as a food preservative to inhibit the growth of mold, yeast, and bacteria. It is often found in products with a high water content, such as cheeses, yogurt, dried fruits, and beverages like fruit juices and carbonated drinks.

Potassium sorbate is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is poorly absorbed by the body and is broken down into compounds that are naturally found in the body. JECFA and EFSA have evaluated potassium sorbate and established acceptable daily intakes. Some individuals may experience allergic reactions or sensitivities, such as skin rashes or digestive upset, though this is rare.
