Originally developed by German researchers in 1967, acesulfame potassium was first approved for use in Europe in 1983. Five years later, in 1988, it was approved in the U.S. Today, it is often used in combination with other low- and no-calorie sweeteners, such as aspartame and sucralose, to provide a more sugar-like taste than acesulfame potassium provides on its own.

While Diet Coke uses aspartame as its sweetening agent, Coke Zero uses both aspartame and acesulfame potassium, also called “Ace K” or “acesulfame K.” Acesulfame potassium is another calorie-free sweetener that passes through the body without raising blood sugar levels.
