Description: Aspartame is an artificial, non-saccharide sweetener used as a sugar substitute in some foods and beverages. Aspartame is approximately 200 times sweeter than sucrose (table sugar). Due to this property, even though aspartame produces four kilocalories of energy per gram when metabolized, the quantity of aspartame needed to produce a sweet taste is so small that its caloric contribution is negligible.
