Abstract:In order to investigate the antioxidant activity of Maillard reaction products (MRPs)in the metha-nol solvent,the glycine-glucose simulation system was adopted,with DPPH free radical scavenging as antioxi-dant 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 tempera-ture,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 con-centration 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 fol-lows:temperature 127 ℃,60 min reaction time,initial pH=8.0,the ratio of glycine and glucose 2.51 .
