Acesulfame potassium is a colorless to white crystalline powder, odorless, with a strong sweet taste, about 150 times as sweet as sucrose, and tastes similar to saccharin. High concentration has a bitter taste. With sugar alcohol, sucrose, and other good mixture, and stable. The melting point is about 225℃, the absorption spectrum is 227nm, density is 1.83g/m3 (loose density 1.1~1.3kg/dm3). Not hygroscopic, stable at room temperature. Soluble in water (30g/100ml, 20℃), slightly soluble in ethanol and other solvents.
Function:
1) 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.
2) 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.
3) It is also used as a sweetener in protein shakes and pharmaceutical products, especially chewable and liquid medications, where it can make the active ingredients more palatable.
Application:
1) Common applications of acesulfame-K are table uses, chewing gums, beverages, foods, bakery products, confectionary, oral hygiene products, and pharmaceuticals.
