Acesulfame-K
Description
White crystalline powder odorless with strong sweet taste, its dilute solution is approximately 200 times sweeter than sugar,
having a taste closely similar to that of cane sugar possessing a clean sweet taste of sugar without any bitter or metallic taste,
the PH value of its aqueous solution (0.8%) being 4-6.5, unstable in aqueous solution easily decompose to lose sweet taste,
rather stable at low temp, and PH value being 3-5 slightly soluble in water (approximately 1%) and in ethyl alcohol(0.26mg/100ml).
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 carbonate 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,
especially chewable and liquid medications, where it can make the active ingredients more palatable.
■ Application
Acesulfame-K is widely used in various kind of food. Acesulfame-K is the most suitable sweetener for soft beverage because of it's
high stability and good taste, it can be used in such foodstuffs as sweetener: Soft drink, chewing gum, coffee(instant), tea(instand),
dairy product analogs, gelatins, pudding desserts, tabletop sweetener and baked food. Acesulfame-K can be also used in medicine and
cosmetics, for example, syrup, sugarcoating pius, toothpaster, lipstick, mouthwasher and similar products.
