Potassium Sorbate

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.
