Acesulfame potassium, also known as acesulfame K or ace K, is a calorie-free artificial sweetener, and marketed under the trade names Sunett and Sweet One.
Acesulfame K is 180-200 times sweeter than sucrose (table sugar), as sweet as aspartame, about half as sweet as saccharin, and one-quarter as sweet as sucralose. Like saccharin, it has a slightly bitter aftertaste, especially at high concentrations.
Although the United States Food and Drug Administration (USFDA) has approved ace-k for use as general-purpose sweetening agent, there is concern as to its safety and some research shows acesulfame potassium may be carcinogenic.
Special Note: Healing Gourmet does not endorse artificial sweeteners of any kind. Acesulfame-K is on Whole Foods Market List of Unacceptable Ingredients.
