name:Potassium Sorbate
Formula:C6H7KO2
M.W:150.22
CAS NO.:24634-61-5
Characters:White or white powder or granule.Odorless or characteristic odour, long placed in the air, easy to absorb moisture and oxidize decomposition and colouring.Melting point: 270 ℃ (decomposition).Solubility (20 ℃, and 100 g/ml) : 67.6 water, propylene glycol, 5.8 ethanol 0.3.Soluble in water.
Usage:Preservatives, antioxidants, stabilizers.Potassium sorbate is a new, safe, non-toxic, efficient food additive, is not saturated fatty acid potassium, enter human body participate in normal metabolism of fat, after finally oxidized into water and carbon dioxide, and will not accumulate in the body, has the very high security, and its toxicity is only 1/2 of salt, is 1/40 of the sodium benzoate, is internationally recognized as one of the best food additives.Potassium sorbate to mold, yeast and aerobic bacteria have obvious inhibitory effect, its inhibitory effect of the development of stronger than bactericidal action, combined with microbial enzyme system in the sulphur, thereby destroying enzyme activity, antibacterial, anticorrosive.It also prevents the growth and reproduction of harmful microorganisms such as botox, staphylococcus and salmonella.Under acidic conditions (pH below 5 ~ 6), the antibacterial effect was better.Thus, it can effectively prolong the preservation time of food and maintain the flavor of the original food.However, the beneficial microorganisms such as anaerobic bacillus and acidophilus are almost ineffectual.
