Potassium Sorbate: Preservative

Potassium sorbate is the potassium salt of sorbic acid. It is a naturally occurring compound found in some plants, but it is typically produced synthetically for use as a food additive. It is manufactured by neutralizing sorbic acid with potassium hydroxide.

Potassium sorbate is used as a preservative to inhibit the growth of mold, yeast, and bacteria in foods. This helps to extend the shelf life of products and prevent spoilage. It is commonly found in baked goods like cakes and cookies, as well as in cheeses, yogurt, dried fruits, and beverages.

In the United States, potassium sorbate is generally recognized as safe (GRAS) by the FDA for use as a food preservative. International bodies like JECFA and EFSA have also evaluated potassium sorbate and established acceptable daily intake levels. At typical consumption levels, it is considered safe for most people. Some individuals may experience mild allergic reactions or skin sensitivities, though this is rare.
