Potassium Sorbate is often used as a preservative. It destroys many enzyme systems by combining with the sulfhydryl group of microbial enzyme system. Its toxicity is much lower than that of other preservatives. At present, it is widely used. Potassium sorbate can give full play to its anti-corrosion effect in acidic medium and has little anti-corrosion effect under neutral conditions.

Potassium sorbate is mainly used as food preservative. It is widely used because of its strong inhibition of mold and spoilage bacteria and easy dissolution in water. Potassium sorbate has been recommended by FAO as a safe and efficient food preservative. Potassium sorbate has the characteristics of low toxicity, good anti mildew effect, no change in the original properties of food, convenient use and wide application range. Therefore, many foreign developed countries have widely used potassium sorbate as a good and efficient preservative in food. At present, potassium sorbate is also widely used in the domestic food industry. With the continuous breakthrough of production cost and production technology, the application scope of potassium sorbate as a low toxicity, safe and efficient food preservative will continue to expand
