Metabolite Identification
Common NameNeotame
DescriptionPotential high-intensity sweetener, sweetness variously stated to be 40 x sucrose and 7000-13000 x sucrose Neotame is an artificial sweetener made by NutraSweet that is between 7,000 and 13,000 times sweeter than sucrose (table sugar). In the European Union it is known by the E number E961. Neotame is moderately heat stable and extremely potent. Neotame is rapidly metabolized, completely eliminated, and does not accumulate in the body
