Potassium Sorbate 

Potassium sorbate (2.4-di-ethene acid kalium) is a white powder used as a preservative. It is a highly-effective preservative recommended by FAO and WHO. Potassium Sorbate can inhibit the activity of fungus, yeast and aerobic bacterium, and prevent the growth and reproduction of botulinum, staphylococcus, salmonella and other harmful microorganisms. Moreover, it has no effect to beneficial microorganisms, such as anaerobic bacillus and acidophilus lactobacillus.

Having a stronger inhibition effect than sterilization effect, it can effectively prolong the preservation time of the food without changing the original flavor. The antisepsis effect of Potassium Sorbate is 5-10 times as much as that of sodium benzoate. It is widely used in food, beverages, tobacco, pesticides, cosmetics and other industries. As an unsaturated acid, it also can be used for resins, spices and rubber industry.
