Description and Uses

Aspartame is a synthetic non-caloric sweetener that is metabolized to phenylalanine, aspartic acid, and methanol in the gut. Aspartame (80 mg/kg per day for 90 days) increases plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activity, induces hepatocyte degeneration and leukocyte infiltration in the liver, and reduces hepatic levels of reduced glutathione (GSH), oxidized glutathione (GSSG), and γ-glutamylcysteine (γ-GC) in mice. Formulations containing aspartame have been used as sweetening agents and flavor enhancers in foods and beverages.

Aspartame in powder form for limited uses such as cereals, powdered drinks, and chewing gum. When aspartame is used in baked goods and baking mixes, it should not exceed 0.5% by weight. Packages of the dry, free-fl owing aspartame are required to prominently display the sweetening equivalence in teaspoons of sugar.
