TUODA-Potassium sorbate

Properties White to light yellow flaky crystals, crystalline powder or granular. Odorless or slightly odorous. It is easy to absorb moisture and oxidatively decompose when stored in the air for a long time. Soluble in water. Soluble in propylene glycol and ethanol. Sorbic acid (potassium) is stable in a sealed state, but it is easy to absorb water, oxidize and color when exposed to humid air. Potassium sorbate has good thermal stability and its decomposition temperature is as high as 270℃. Uses Potassium sorbate is mainly used as a food preservative, and is also used in cosmetics preservation and feed mildew prevention. It has a strong inhibitory effect on spoilage bacteria and mold, and is easily soluble in water and is widely used. Its antibacterial effect is stronger than its bactericidal effect. The lower the pH value, the stronger the antibacterial effect. Sorbic acid (potassium) can effectively inhibit the activity of molds, yeasts and aerobic bacteria, and can also prevent the growth and reproduction of harmful microorganisms such as Clostridium botulinum, Staphylococcus aureus, and Salmonella, but it is almost ineffective against beneficial microorganisms such as anaerobic spore-forming bacteria and Lactobacillus acidophilus. Its growth inhibition effect is stronger than its bactericidal effect, thus effectively extending the shelf life of food and maintaining the original flavor of food. Its preservative effect is 5-10 times that of similar products such as sodium benzoate. As a cosmetic preservative
