Description and Uses

Acesulfame potassium is approved for use in food as a sweetener. It is included in the ingredient list on the food label as acesulfame K, acesulfame potassium, or Ace-K.  Acesulfame potassium (Ace-K) is regulates  as a food additive. The FDA approved acesulfame potassium for use in specific food and beverage categories in 1988 and in 2003 approved it as a general-purpose sweetener and flavor enhancer in food, except in meat and poultry, under certain conditions of use.  It is widely used in the food industry, such as mouthwash and soft drinks. However, some researches have found that it does harm to the liver and nervous system[1-2].

Acesulfame-K is the potassium salt of 6-methyl-l,2,3-oxathiazin-4(3H)- one-2,2-dioxide. This sweetener was discovered in Germany and was first approved by the FDA in 1988 for use as a nonnutritive sweetener. The complex chemical name of this substance led to the creation of the trademark common name, acesulfame-K, which is based on its following relationships to acetocetic acid and sulfanic acid, and to its potassium salt nature.
Acesulfame-K is 200 times as sweet as sugar and is not metabolized and is thus noncaloric. It is exceptionally stable at elevated temperatures encountered in baking, and it is also stable in acidic products, such as carbonated soft drinks. It has a synergistic effect when mixed with other low-calorie sweetners, such as aspartame. Common applications of acesulfame-K are table uses, chewing gums, beverages, foods, bakery products, confectionary, oral hygiene products, and pharmaceuticals.
