Potassium sorbate
China [CN] Potassium sorbate is mainly used as a food preservative, and is also applied in cosmetic preservation and feed mold prevention, etc. It has a strong inhibitory effect on putrefactive bacteria and mold, and is also highly soluble in water, thus being widely applied. Its antibacterial growth effect is stronger than its bactericidal effect. The lower the PH value, the stronger the antibacterial effect. Sorbate (potassium) can effectively inhibit the activity of molds, yeasts and aerobic bacteria, and also prevent the growth and reproduction of harmful microorganisms such as botulinum, Staphylococcus and Salmonella. However, it is almost ineffective against beneficial microorganisms such as anaerobic spore-forming bacteria and Lactobacillus acidophilus. Its inhibitory effect on development is stronger than its bactericidal effect. This can effectively extend the shelf life of food and maintain its original flavor. Its anti-corrosion effect is 5 to 10 times that of sodium benzoate, a similar product.
