Potassium Sorbate

Potassium Sorbate



Purity:98-101%
Standard :FCCIV/FCCV/E202
Grade:Food grade



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.
