The free acid form of the sweetener has a distinct melting point of 123.5 ☌.Īcesulfame K has a specific density of 1.83. Reproduced from Acesulphame/Acesulfame, Encyclopaedia of Food Science, Food Technology and Nutrition, Macrae R, Robinson RK and Sadler MJ (eds), 1993, Academic Press.Īcesulfame K is a white crystalline material which is stable up to 250 ☌, at which temperature it decomposes. Synthesis of the acesulfame ring structure using fluorosulfonyl isocyanate and tert-butylacetoacetate as starting materials. The EDI is estimated at 20% of the ADI because of its intense sweetening power.įigure 2. The amount of acesulfame-K added to food products is very small because of its intense sweetening power and because it is often used in combination with other sweeteners. The European Commission's Scientific Committee on food reevaluated this sweetener and supported its safety but recommended an ADI from 9 mg kg − 1 to 15 mg kg − 1 bw per day. Acesulfame-K or Ace-k is often blended with other sweeteners (usually sucralose or aspartame) whereby each sweetener masks the other's after taste and exhibit a synergistic effect by which the blend is sweeter than its components. It is heat stable so it can be used in cooking and baking. Acesulfame-k is a white crystalline, water soluble powder, which is roughly 120 times sweeter than sucrose.

Neutralization with potassium hydroxide gives Acesulfame-K ( Clauss et al., 1993).

This results in formation of N-sulfoacetoacetamide, which is then dehydrated by sulfur trioxide to form oxathiaazinone dioxide. Synthesis of Acesulfame-K involves the treatment of acetoacetamide with at least two equivalents of sulfur trioxide. Runu Chakraborty, Arpita Das, in Encyclopedia of Food Chemistry, 2019 Acesulfame-kĪcesulfame-k, a high intensity sweetener, is a potassium salt of 6-methyl-123-axathiazine-4 (3H)-one 2, 2-dioxide with molecular formula C 4H 4KNO 4S and molecular weight of 201.24 was developed as sweetener by Hoechst.
