APPLICATIONS

Potassium sorbate can effectively inhibit the survival of mold, yeast and aerobic bacteria, and also can prevent the growth and reproduction of harmful microorganisms such as botulinum, staphylococcus, salmonella, etc., but to beneficial microorganisms such as anaerobic spores bacteria and lactobacillus acidophilus are almost ineffective, their role in inhibiting development is stronger than that of bactericidal action, so as to effectively extend the preservation time of foods and maintain the flavor of the original food.
Potassium sorbate antiseptic effect is 5-10 times that of similar products sodium benzoate.
Currently Potassium sorbate has been widely used in food, beverage, pickles, tobacco, pharmaceuticals, cosmetics, agricultural products, feed and other industries. From the development trend, the scope of its application is still expanding.
Potassium sorbate is an acidic preservative and has good antiseptic effect in foods close to neutral (PH6.0---6.5), while the antisepsis effect of benzoic acid (sodium) is dropped significantly and has a bad taste at PH>4.
