Acesulfame K, also known as acesulfame potassium, is indeed a powerful artificial sweetener. It is approximately 200 times sweeter than sucrose (table sugar), making it a popular choice in low-calorie and sugar-free products.
Its sweetness profile allows it to be blended with other sweeteners, like sucralose or aspartame, to enhance flavor and achieve a more sugar-like taste. This blending can also help mask any aftertastes that some sweeteners might have.
