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.
Function&Application:
Potassium sorbate is a commonly used food preservative. Specifically, it is the crystalline salt of sorbic acid, also a food preservative. It is frequently used in the manufacture of mass-market cheeses, wines, meats, and dried fruits. Some cosmetics and personal care manufacturers use it, too, often because of how well the compound helps inhibit the growth of yeast and mold, thus extending shelf life. With a toxicity level comparable to table salt, the compound is generally considered safe for consumption; still, there is some controversy when it comes to whether the compound is the best preservative option where overall health is concerned. People who consume a lot of processed foods may take in much more than trace amounts, usually from various foods. Side effects are usually thought to be rare but may include mild allergic reactions and nausea.
