1、Chemical Name:Potassium sorbate
2、Molecular Formula : C6H7KO2
3、Molecular Weight:150.22
4、CAS: 590-00-1
5、Character: White to light yellow, flaky crystalline granule or powder. Odorless or slight odor. It is deliquescent, decomposed and coloring which stored in air for long time. Relative density is 1.363. Melting point is 270℃(decomposed). Highly soluble in water. The PH value of aqueous solution with 1%is between 7 and 8.
6、Usage: Preservative; Mildew-retarding agent. As a high-effective preservative recommended by FAO and WHO, Potassium Sorbate can inhibit the activity of fungus, yeast and aerobic bacterium, and prevent the growth and reproduction of botulinum, staphylococcus, salmonella and other harmful microorganisms. Moreover,Potassium Sorbatev has no effect to beneficial microorganisms, such as anaerobic bacillus and acidophilus lactobacillus. Having a stronger inhibition effect than sterilization effect,Potassium Sorbate can effectively prolong the preservation time of the food without changing the original flavor. The antisepsis effect of Potassium Sorbate is 5-10 times as much as that of sodium benzoate.
7、Packing:It is packed with polythene bag as the inner layer, and polywoven bag as the outer layer. The net weight of each bag is 25kg.
8、Storage and Transport: It should be stored in a dry, clean, and ventilativewarehouse, kept away from water and moisture during transport, unload with care so as to avoid damaging the bags. Be cautious to keep away from moisture and hot.
