The effect of solvents on the thermal degradation products of two Amadori derivatives.

ABSTRACT: To enrich the flavor additives of the Maillard reaction, two Amadori analogs, N-(1-deoxy-d-fructosyl-1-yl)-l-phenylalanine ester (Derivative 1) and di-O-isopropylidene-2,3:4,5-β-d-fructopyranosyl phenylalanine ester (Derivative 2), were chemically synthesized starting from d-fructose. The samples were reacted at 120 and 180 °C for 2 h, and the effects of solvents (water and ethanol) on their degradation products were studied. The analyses of thermogravimetry (TG), derivative thermogravimetry (DTG), differential scanning calorimetry (DSC), and gas chromatography-mass spectrometry (GC/MS) were used to investigate the thermal behavior and degradation products of the samples. TG-DTG curves show that the T _p values of the samples corresponding to the largest mass
