【CAS】24634-61-5
Alias: Potassium 2, 4-hexadienate
Molecular formula；C6H7KO2
Structural formula:
1. Product Property
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.

3、Application scope and Usage
Sorbate (potassium) can effectively inhibit the activity of mold, yeast 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, thereby effectively extending the shelf life of food. And maintain the original flavor of the food.
4、Package and Storage
Potassium sorbate is typically packaged in sealed plastic bags, aluminum foil bags, or fiber drums to prevent moisture. For storage, keep it in a cool, dry, well-ventilated area away from heat, light, and incompatible substances like strong oxidizers. Ensure containers are tightly closed when not in use to maintain stability and extend shelf life.
