Main uses:

Preservatives, antioxidants, stabilizers. Potassium sorbate is a new, safe, non-toxic and efficient food additive, is the unsaturated fatty acid potassium salt, into the body after the normal fat metabolism, and finally oxidized into water and Carbon dioxide, will not accumulate in the human body, High safety, its toxicity is only 1/2 of the salt, sodium benzoate is 1/40, is internationally recognized as the best food additives. Potassium sorbate has a significant inhibitory effect on mold, yeast and aerobic bacteria, and its inhibitory effect is stronger than bactericidal effect, combined with mercapto group in microbial enzyme system, thus destroying enzyme activity and achieving bactericidal and anticorrosive purposes. But also to prevent the growth and reproduction of harmful microorganisms such as Botox, Staphylococcus, Salmonella and the like. Under acidic conditions (pH below 5 ~ 6), the antibacterial effect is better. So as to effectively extend the preservation of food time, and to maintain the flavor of the original food. But the anaerobic Bacillus and Lactobacillus acidophilus and other beneficial microorganisms are almost ineffective.
