aspartame [uh–spahr-teym, a-spahr-, as-per-teym] noun
A low-calorie artificial sweetener popularly known as NutraSweet and Equal. Aspartame is white and crystalline in appearance as well as odorless and somewhat water-soluble.

Almost 200 times as sweet as sugar, aspartame was first synthesized in 1965 and controversies about its potential health dangers continue to flare.
