Excellent Preservative Properties：
Potassium Sorbate can restrain effectively the activity of mould, yeast and aerophile bacteria. Restrain growth and reproduction of the pernicious micro-organism as pseudomonas staphylococcus salmonella action to restrain growth is more powerful than killing. Meanwhile it can not restrain useful microorganism growth as anaerobic spore-bearing bacilli, cidophil therefore to lengthen food store period and remain food original flavor, the preservative efficiency of potassium sorbate is 5-10 times sodium benzoate.

High safety：
Potassium sorbate is one kind of nonsaturated fatty acid compounds. It can be absorbed by human body rapidly, then decomposed into CO2 and H2O, moreover no remaining in body.


Potassium Sorbate
Potassium Sorbate has been used extensively in food, drink, vegetables in soy, tobacco, drugs, cosmetics, agricultural products, forage and other domain. Its application should become wider in the world.

As acidic preservative, Potassium sorbate is also used well in neutral food(pH6.0-6.5). The preservative efficiency of sodium
benzoate will decrease clearly and have a bad taste at pH>4.

Potassium Sorbate can be used by direct adding, spraying, retting, dry spraying, using in packing material and other method.
