Product Description
99% purity Potassium sorbate CAS 24634-61-5Product Description
As a high-effective preservative recommended by FAO and WHO, 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.
Potassium sorbate, the potassium salt of sorbic acid, is a commonly used preservative in food with the European food additive number E202. Generally, it is synthetic, vegan and gluten-free.
This ingredient is used to protect food from spoilage and therefore prolong the food shelf life by slowing the growth of molds and yeasts. You may have seen it in the label of wines, cheeses, cider, mead, soft drinks, and baked goods
Application: Used as food additive of cream, salad, fruit, wine, candies.
Excellent Preservative Properties
Potassium Sorbate can restrain effectively the activity of mould, yeast and aerophile bacteria. 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 microorganism growth as anaerobic spore-bearing bacilli, cidophil therefore to lengthen food store period and remain food original flavor, the preservative efficiency of potassium sorbate is 5-10 times sodium benzoate.
High safety
Potassium sorbate is one kind of nonsaturated fatty acid compounds. It can be absorbed by human body rapidly, then decomposed into CO2 and H2O, moreover no remaining in body.
ADI 0-25mg/kg (based on sorbic acid FAO/WHO 1994)
LD50 4920mg/kg (large mouse by mouth)
GRAS (FDA, 182.3640 1994)
Its toxicity only 1/12 times table salts and 1/40 times of sodium benzoate.
Good Stability
Potassium Sorbate is stable in sealed status, will not be decomposed until 270 degrees centigrade. It will be oxidized into colored ones and absorbing moisture in case exposed in air for a long time.
Wide Application
At the moment, Potassium Sorbate has been used extensively in food, drink, vegetables in soy, tobacco, drugs, cosmetics, agricultural products, forage and other domain. Its application should become wider in the world.
As acidic preservative, Potassium sorbate is also used well in neutral food(pH6.0-6.5). The preservative efficiency of sodium benzoate will decrease clearly and have a bad taste at pH>4.
Application flexibility
Potassium Sorbate can be used by direct adding, spraying, retting, dry spraying, using in packing material and other method.
