Aspartame
Aspartame (APM) is an artificial non-saccharide sweetener used as a sugar substitute in some foods and beverages. In the European Union, it is codified as E951. Aspartame is a methyl ester of the aspartic acid/phenylalanine dipeptide.
A panel of experts set up by the European Food Safety Authority concluded in 2013 that aspartame is safe for human consumption at current levels of exposure.
