Potassium Sorbate A Preservative

Potassium sorbate is the potassium salt of sorbic acid, a naturally occurring organic compound. It is typically manufactured synthetically from chemicals derived from petroleum. It is a white crystalline powder that dissolves easily in water.

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

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. While generally considered safe at typical consumption levels, some individuals may experience mild allergic reactions or sensitivities, such as skin rashes or digestive upset. Research on its long-term health effects is ongoing.
