Acesulfame potassium — usually shortened to acesulfame-K or Ace-K — is a heat-stable, high-intensity artificial sweetener about 200 times sweeter than table sugar. A white, odourless crystalline powder, it adds no calories, survives baking and long storage, and is blended into thousands of diet and no-sugar-added products, most often alongside aspartame or sucralose.
