Acesulfame potassium also known as acesulfame K (K is the symbol for potassium) or Ace K, is a calorie-free sugar substitute (artificial sweetener) often marketed under the trade names Sunett and Sweet One. In the European Union, it is known under the E number (additive code) E950. It was discovered accidentally in 1967 by German chemist Karl Clauss at Hoechst AG (now Nutrinova).[3] In chemical structure, acesulfame potassium is the potassium salt of 6-methyl-1,2,3-oxathiazine-4(3H)-one 2,2-dioxide. It is a white crystalline powder with molecular formula C4H4KNO4S and a molecular weight of 201.24 g/mol.
Functions and Applications
1. Acesulfame-K is widely used in various kind of food.
2. Acesulfame-K is the most suitable sweetener for soft veverage because of it's high stability and good taste, it can be used in such foodstuffs as sweetener: soft drink, chewing gum, coffee(instant), tea(instand), dairy product analogs, gelatins, pudding desserts, tabletop sweetener and baked food.
