Acesulfame Potassium, commonly known as A.K, is a no-calorie sweetener. The sweetness of acesulfame potassium is 200 times that of sucrose, equivalent to aspartame, two-thirds of saccharin, and one-third of sucralose. Acesulfame potassium has a functional group similar to that of saccharin, and it will also leave a slight bitter taste and metallic taste on the tongue after eating, especially when the concentration is higher. In actual use, acesulfame potassium is mixed with other sweeteners such as sucralose and aspartame in order to obtain a sweetness profile similar to that of sucrose, or to cover the residual taste of each other, or to present a synergistic effect to promote the overall sweetness. The molecular size of acesulfame potassium is smaller than that of sucrose, so it can be mixed evenly with other sweeteners.
Unlike aspartame, acesulfame potassium is stable to heat, even in a weak acid and weak base environment, it still has good thermal stability. Therefore, it can be used for baking, as well as foods that have been placed in the baking window for a long time.
