Acesulfame-K FCC4 Product Name:Acesulfame-K FCC4Packing:25kg/drum ,20MT/20'FCLCAS  NO:33665-90-6Molecular Formula:C4H5NO4S, C4H4KNO4SMolecular Structure: Physico-chemical properties:Appearance: Crystalline Powder  Purity: 99% MinPicture: Acesulfame K is 180-200 times sweeter than sucrose (table sugar), as sweet as aspartame, about half as sweet as saccharin, and one-quarter as sweet as sucralose. Like saccharin, it has a slightly bitter aftertaste, especially at high concentrations. Kraft Foods has patented the use of sodium ferulate to mask acesulfame's aftertaste. Acesulfame K is often blended with other sweeteners (usually sucralose or aspartame). These blends are reputed to give a more sugar-like taste whereby each sweetener masks the other's aftertaste, and/or exhibits a synergistic effect by which the blend is sweeter than its components.Specification: AppearanceWhite crystalline powderAssay99.0% ~101.0%Solubility in waterFree solubleSolubility in alcoholSlightly solubleUltraviolet absorption227±2nmTest for potassiumPositivePrecipitation testYellow precipitatePotassium17.0 ~ 21.0%Loss on drying≤0.5%Organic impurities≤20mg/kgFluoride≤3mg/kgHeavy metals≤5mg/kgLead≤1mg/kgArsenic≤3mg/kgSelenium≤10mg/kgPH5.5 ~ 7.5
