Potassium Sorbate is a chemical salt, composed of potassium and sorbic acid. It is a white colored crystalline solid, generally used in the form of a powder. It has a chemical formula of C6H7KO2. This chemical has several uses, but it is most commonly used as a preservative. It retards yeasts, molds and other fungi, which makes it beneficial to use in many foods (such as canned foods, dairy products, baked goods, fruit juices and carbonated beverages), wines, and cosmetics. It is also used as intermediate for plasticizers and lubricants.[1]


Potassium sorbate has been classified as non-toxic, and safe for use in food. However, some studies have suggested that it actually may be toxic and contribute to if not cause several long-term health problems.[2]
