As Preservative

Potassium sorbate is a salt of sorbic acid, a naturally occurring compound found in some plants. It is manufactured industrially by reacting sorbic acid with potassium hydroxide. It appears as a white crystalline powder or granules.

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. It is commonly found in baked goods, dairy products, beverages, and dried fruits.

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 intakes. Studies on potassium sorbate at typical consumption levels have not shown significant adverse health effects. Some individuals may experience mild allergic reactions or sensitivities, though this is rare.
