Introduction：Aspartame is an artificial, non-saccharide sweetener used as a sugar substitute in some foods and beverages. Aspartame is a methyl ester of the aspartic acid/ phenylalanine dipeptide. It is incompatible with strong oxidizing agents. When heated to decomposition, it emits carbon monoxide, oxides of nitrogen, carbon dioxide. It was first synthesized in 1965.
Aspartame is safe at current levels of consumption as a non-nutritive sweetener.
