3. Aspartame Chemistry:
Aspartame, is a methyl ester of the dipeptide of the natural amino acids L-aspartic acid and L-phenylalanine. Under strongly acidic or alkaline conditions, aspartame may generate methanol by hydrolysis. Under more severe conditions, the peptide bonds are also hydrolyzed, resulting in the free amino acids.
Â
As aspartame manufartrurer, there are two approaches to synthesis which are used commercially. In the chemical synthesis, the two carboxyl groups of aspartic acid are joined into an anhydride and the amino group is protected by a compound that will prevent further reactions of that group. Phenylalanine is methylated and combined with the N-protected aspartic anhydride, then the blocking group is removed from aspartic acid by acid hydrolysis. The drawback of this technique is that a byproduct, the bitter tasting β-form, is produced when the wrong carboxyl group from aspartic acid links to phenylalanine.
