Description
Potassium sorbate is the potassium salt of sorbic acid, chemical formula CH3CH=CH−CH=CH−CO2K. It is awhite salt that is very soluble in water (58.2% at 20 °C). It is primarily used as a food preservative (E number202). Potassium sorbate is effective in a variety of applications including food, wine, and personal-car
eproducts. While sorbic acid occurs naturally in some berries, virtually all of the world's production of sorbicacid, from which potassium sorbate is derived, is manufactured synthetically.
