Antioxidative activities of Maillard reaction products (MRPs) derived from gelatin hydrolysate (GH) of unicorn leatherjacket skin as affected by types of saccharides, GH to saccharide ratio, incubation temperatures, relative humidity (RH), and times were investigated. MRPs prepared using mixture of GH and galactose at 2:1 (w/w) ratio showed the highest antioxidative activity. At different incubation temperatures (50–70°C) and RHs (55–75%), optimal condition for preparing antioxidative MRPs included heating GH and galactose (2:1) powder at 70°C and 55% RH for 36 h. Electrophoresis and Fourier transform infrared spectroscopy revealed the formation of high molecular weight polymers, and the advanced glycation took place in MRPs.  相似文献
