The influence of Cu2+, Fe2+ on the Maillard reaction were studied by heating L-ascorbic(ASA) and glycine (Gly) solutions adjusted to pH 5 at 120±2°C for 140 min in an oil bath. The presence of metals affected the intensity of browning and intermediate products, as monitored by absorbance at 420 nm and absorbance at 294 nm, sharply increased with the increase of metal concentrations applied (0.000M, 0.005M, 0.010M, 0.015M, 0.020M). Thereafter, slight increases were observed up to 0.020M. Antioxidative activity of all MRPs derived from ASA-Gly model systems sharply increased at 0.015M (P < 0.05) and slightly changes in activity were found with increasing metal concentrations up to 0.020M. Moreover, radical-scavenging activity correlated well with browning intensity and absorbance at 294 nm.
