What is acesulfam K?

Acesulfame K, or acesulfame potassium, is a low-calorie sweetener approved for use since 1988. It is an organic synthetic salt. It is 200 times sweeter than saccharose (sucrose), has a synergistic sweetening effect with other sweeteners, has a stable shelf-life and is heat stable. It is excreted through the human digestive system unchanged, and is therefore non-caloric.
