Potassium Sorbate

Potassium sorbate is a potassium salt of sorbic acid. While sorbic acid is found naturally in some fruits, the potassium sorbate used in food is typically produced synthetically. It appears as a white, crystalline powder.

Manufacturers add potassium sorbate primarily as a preservative to prevent the growth of mold, yeast, and some bacteria. This helps to extend the shelf life of various foods and beverages. It is commonly found in cheese, baked goods, yogurt, wine, and fruit products.

The U.S. Food and Drug Administration (FDA) considers potassium sorbate to be Generally Recognized As Safe (GRAS) for use in food. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated potassium sorbate and established an acceptable daily intake. The European Food Safety Authority (EFSA) has also evaluated it and concluded it is safe for use as a food additive. At typical intake levels, it is generally considered safe, though some individuals may experience mild allergic reactions like skin irritation, which is rare.
