Potassium sorbate is the potassium salt of sorbic acid and is one of the approved preservatives in China. It is a white to light yellow flake-like crystal, crystal particles or crystal powder. Potassium sorbate is mainly used as a food preservative, and is also used for cosmetics preservation and feed anti-mildew, etc. It has a strong inhibitory effect on spoilage bacteria and molds, and is easily soluble in water, thus being widely used. Its inhibitory effect on bacterial growth is stronger than its bactericidal effect. The stronger the pH value, the stronger the antibacterial effect.
