Acesulfame potassium is an artificial calorie-free sweetener that is 100-200 times sweeter than table sugar. It is used extensively in commercial baked goods, diet sodas, and other low sugar or calorie products. It is marketed under the brand name Ace-K.
There is some controversy regarding the safety of acesulfame potassium in food.
Accesulfame and Cyclamate are more effective used together than individually. This manner of blending not only increases the sweetness but is also known to reduce the bitter off-taste of Saccharin and Acesulfame, due to which Acesulfame is so commonly found paired-up.
