The Maillard reaction comprises a complex network of reactions which has pr
oven to be of great importance in both food science and medicine. The major
ity of methods developed for studying the Maillard reaction in food have fo
cused on model systems containing amino acids and monosaccharides. In this
study, a number of electrophoretic techniques, including two-dimensional ge
l electrophoresis and capillary electrophoresis, are presented. These have
been developed specifically for the analysis of the Maillard reaction of fo
od proteins, and are giving important insights into this complex process.
