Chemical Information
FooDB NameAlitame
DescriptionSweetening agent. Intensely sweet, approx. 2000 x sucrose. Use currently (1999) permitted in Australia, New Zealand, Indonesia and China Alitame is an artificial sweetener developed by Pfizer in the early 1980s and currently marketed in some countries under the brand name Aclame. Like aspartame, alitame is an aspartic acid-containing dipeptide. Most dipeptides are not sweet, but the unexpected discovery of aspartame in 1965 led to a search for similar compounds that shared its sweetness. Alitame is one such second-generation dipeptide sweetener. Neotame, developed by the owners of the NutraSweet brand, is another.
