N-[N-(3,3-dimethylbutyl)-L--aspartyl]-L-phenylalanine 1-methyl ester
Neotame is an artificial sweetener designed to overcome some of the
The dimethylbutyl part of the molecule was added to block the action
of peptidases, enzymes that break the peptide bond between the two
amino acids aspartic acid and phenylalanine. This reduces the
availability of phenylalanine, eliminating the need for a warning
on labels directed at people who cannot properly metabolize
Neotame does not break down with the heat of cooking, another
drawback to aspartame.
Neotame is also 30 times sweeter than aspartame, so less of it is
needed to sweeten a product.
Neotame is about 8,000 times sweeter than sugar, so only 6 milligrams
is needed to sweeten a typical 12 ounce soft drink.
Neotame is used in tabletop sweeteners, frozen desserts, chewing gum
and candy, baked goods, fruit spreads, and ready-to-eat cereals.
