About Acesulfame K

Acesulfame K is 200 times sweeter than sucrose (common sugar), as sweet as aspartame, about 2/3 as sweet as saccharin, and 1/3 as sweet as sucralose. Like saccharin, it has a slightly bitter aftertaste, especially at high concentrations. Kraft Foods has patented the use of sodium ferulate to mask acesulfame's aftertaste.[4] Acesulfame K is often blended with other sweeteners (usually sucralose or aspartame). These blends are reputed to give a more sucrose like taste whereby each sweetener masks the other's aftertaste, and/or exhibits a synergistic effect by which the blend is sweeter than its components.

Unlike aspartame, acesulfame K is stable under heat, even under moderately acidic or basic conditions, allowing it to be used as a food additive in baking, or in products that require a long shelf life. In carbonated drinks, it is almost always used in conjunction with another sweetener, such as aspartame or sucralose. It is also used as a sweetener in protein shakes and pharmaceutical products,[5] especially chewable and liquid medications, where it can make the active ingredients more palatable.

Applications Of Acesulfame K

Acesulfame K is used in mainy applications and in particular in baked goods and in beverages. In carbonated drinks, it is almost always used in conjunction with another sweetener, such as aspartame or sucralose.
