Aspartame or the methyl ester of the Asp-Phe dipeptide (L-aspargine-L-phenylalanine) is a chemical compound that is used as a sweetener, known on foods as E951. Phenylalanine, asparagine and other methyl acids are very common nowadays in food products. Aspartame can be found in products such as low-calorie drinks, chewing gums, soft drinks, table-top sweeteners and recently more and more often in medicines, especially in effervescent tablets.

Aspartame, an artificial sweetener, was invented in 1965 by James M. Schlatter, a chemist working for G.D. Searle & Company. The chemist obtained aspartame as part of research during which he was looking for a medicine for ulcers. He discovered his sweetness when, contrary to health and safety rules, he licked his own finger, soiled with this compound. In 1985, the pharmaceutical company G.D Searle was acquired by the Monsanto group, which continued to produce aspartame under the name NutraSweet Company.
