Potassium Sorbate is White to off-white crystalline powder or granule, odorless or slight characteristic odor. It is easy to absorb moisture and oxidized to be colored. 270deg.c can be decomposition, Solubility(20deg.c,g/100mL): water 67.6; propanediol 5.8; ethanol 0.3; soluble in water.

Potassium Sorbate is a new,safe,nontoxic and effective food preservative and unsaturated fatty acid.It can participate in normal metabolism and finally be oxidized to water and carbon dioxide, does not accumulate in the human body and has high safety,Its toxicity is only half of salt, 1/ 40 of sodium benzoate .Potassium Sorbate has been used in worldwide and successfully used in the food industry in many ways.

Potassium Sorbate can restrain effectively the activity of mould, yeast and aerophile bateria. Restrain growth and reproduction of the pernicious micro organism as pseudomonas, staphylococcus salmonella action to restrain growth is more powerful than killing. Meanwhile, it can not restrain useful microoranganim growth ad Anaerobic-bearing barilli, acidophil therefore to lengthen food store peroid and remain food original flavor. The preservative efficiency of Potassium Sorbate is 5-10 times sodium benzoate,Under acidic conditions (pH value less than 5-6), the effect of bacteriostasis is better, and the food composition has no any impact of preservative effect, so it effectively extends the storage time of food and keep the original flavor of food. However, there is no effect on anaerobic bacteria Bacillus and Lactobacillus acidophilus and other beneficial micro-organisms.
