POTASSIUM SORBATE
= DEFINITION =

Potassium sorbate is the potassium salt of sorbic acid. Its primary use is as a food preservative. Potassium sorbate is effective in a variety of applications including food, wine, and personal care. The molecular weight of this chemical is 150.22 g/molecule. The scientific name is potassium (E,E)-hexa-2,4-dienoate. Potassium sorbate is a white crystalline powder that has antimicrobial properties. It is one of the safest and most commonly used preservatives today. In foods, potassium sorbate increases shelf life and reduces the risk of food-borne illnesses, without adversely affecting taste, color or flavor. It also has several commercial applications in the coatings, rubber and personal car product industries.

= CHEMICAL PROPERTIES =

Potassium sorbate is salt of sorbic acid and is prepared by reacting sorbic acid with potassium hydroxide. It is a white or yellowish crystalline powder or granule. Potassium sorbate is soluble in water. Once dissolved in water, it produces sorbic acid. It is effective as a preservative up to a pH of 6.5. Its effectiveness falls off as pH is lowered. It is inexpensive to, shelf stable and easy to use as an ingredient in foods and other products requiring antimicrobial activity.
