Potassium Sorbate is a new type of food preservative, which can inhibit the growth of bacteria, molds and yeasts without adversely affecting the flavor of food. It involves human metabolism, has personal safety, and is internationally recognized as the best food preservative. Its toxicity is far lower than other preservatives, and it is currently widely used in food. Insen Potassium sorbate can fully exert its antiseptic effect in acidic medium, but has little antiseptic effect under neutral conditions.

1. Potassium sorbate is mainly used as food preservative, also used in cosmetics and feed anti-mildew, etc. It has strong inhibition of putrefying bacteria and mold, and is easily soluble in water and widely used. Its antibacterial effect is stronger than bactericidal effect. The lower PH value is, the stronger antibacterial effect is.
2. Sorbate (potassium) can effectively inhibit the activity of mold, yeast and aerobic bacteria, but also can prevent the growth and reproduction of botulinu m, staphylococcus, salmonella and other harmful microorganisms, but almost ineffective for anaerobic bacillus and lactobacillus acidophilus and other beneficial microorganisms, its inhibiting effect is stronger than sterilization effect, Thus, the preservation time of food can be extended effectively and the flavor of the original food can be maintained. Its anti-corrosion effect is 5-10 times that of similar products sodium benzoate.
3. As a cosmetic preservative
