Acesulfame potassium, commonly known as ace-K, is a non-caloric artificial sweetener used in various food and beverage products. It is approximately 200 times sweeter than sucrose and is often used in conjunction with other sweeteners like aspartame or sucralose to enhance sweetness while reducing the overall caloric content. Acesulfame potassium is stable under heat and has a long shelf-life, making it suitable for a wide range of applications, including baked goods.
