Acesulfame K is widely used as a calorie-free artificial sweetener in various food and beverage products. It is commonly found in soft drinks, baked goods, desserts, and dairy products due to its high stability under heat and acidic conditions. Its sweetening power is approximately 200 times that of sugar, making it an effective sugar substitute for low-calorie and sugar-free diets. Additionally, it is often blended with other sweeteners to enhance flavor and reduce aftertaste. Acesulfame K is also used in pharmaceuticals, such as chewable tablets and liquid medications, to improve palatability without adding calories.
