Potassium sorbate is a chemical additive. It's widely used as a preservative in foods, drinks, and personal care products. It is an odorless and tasteless salt synthetically produced from sorbic acid and potassium hydroxide.

The production of potassium sorbate adopts special advanced technological route, which solves the shortcomings of the traditional technological route at home and abroad, such as yellowish color and poor color stability. The products of our factory are white in color and good color stability.  Potassium sorbate is stable in the sealed state, easy to absorb water when exposed to moist air, oxidation and coloring.  Potassium sorbate has good thermal stability and decomposition temperature up to 270ºC. 

Potassium sorbate can effectively inhibit mold, yeast and oxygen activity of bacteria, also prevent, staphylococcus aureus, salmonella and other harmful microorganism growth and reproduction, but for anaerobic bacillus bacteria and lactobacillus acidophilus beneficial microbes such as null and void, almost against the effect of development was stronger than the sterilization effect, so as to effectively prolong food to save time,  And keep the flavor of the original food.  Its antiseptic effect is 5-10 times that of similar products sodium benzoate. 
At present, it has been widely used in food, beverage, pickles, tobacco, medicine, cosmetics, agricultural products, feed and other industries. From the development trend, its application scope is still expanding.
