  • In order to investigate the antioxidant activity of Maillard reaction products (MRPs) in the methanol solvent,the glycine-glucose simulation system was adopted,with DPPH free radical scavenging as antioxidant activity index of MRPs and pure water system of MRPs antioxidant activity as the contrast.The optimum concentration of methanol was investigated.Under this methanol concentration,the effect of reaction temperature,reaction time,pH and concentration of reactants on MRPs oxidation activity were studied,and optimum technological conditions were obtained by uniform test.The results showed that under the 40% methanol concentration as the solvent of glycine-glucose simulation system,the DPPH free radical scavenging rate of MRPs was the highest,the antioxidant activity was the optimal.The optimum technological conditions were as follows:temperature 127℃,60 min reaction time,initial pH=8.0,the ratio of glycine and glucose 2.5:1.
