Preservative Potassium Sorbate

Potassium sorbate is the potassium salt of sorbic acid, a naturally occurring organic compound. It is typically produced industrially through a chemical process involving the neutralization of sorbic acid with potassium hydroxide. It appears as a white crystalline powder.

Potassium sorbate is widely used as a food preservative. It inhibits the growth of mold, yeast, and some bacteria, helping to extend the shelf life of packaged foods. It is commonly found in baked goods, dairy products, dried fruits, and beverages.

In the U.S., potassium sorbate is generally recognized as safe (GRAS) by the FDA when used as a food preservative. International bodies like JECFA and EFSA have also evaluated potassium sorbate and have established acceptable daily intakes. Studies generally show it to be safe at typical consumption levels, though some individuals may experience mild allergic reactions or sensitivities.
