Potassium sorbate is the potassium salt of sorbic acid. Its primary use is as a food preservative (E number 202). Potassium sorbate is effective in a variety of applications including food, wine, and personal care. 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.
