Potassium Sorbate can effectively inhibit the activity of mold, yeast and aerobic bacteria, so as to effectively prolong the storage time of food and keep the flavor of the original food.It is mainly used as a food preservative, which belongs to the acid preservative and improves the effect of the antiseptic reaction with the organic acid. Made of potassium carbonate or potassium hydroxide and sorbic acid as raw materials. Potassium Sorbate is an efficient and safe antiseptic and antiseptic recommended by FAO and health organization. It is widely used in food, beverage, tobacco, pesticide and cosmetics industry as unsaturated acid, and also in resin, perfume and rubber industry.
