摘  要:
以绿豆分离蛋白(MBPI)和葡聚糖为原料,通过湿热法制备MBPI-Dextran共价复合物。本研究通过测定产物的还原力、DPPH自由基清除能力、超氧阴离子自由基、羟自由基清除能力共同评价糖基化反应对MBPI抗氧化能力的影响。结果表明:MBPI-Dextran共价复合物具有一定的抗氧化能力,特别是90℃条件下反应得到的产物,抗氧化能力较80℃产物显著提升,这与美拉德反应程度有关,较高温度下美拉德反应进程加快,促使更多具有抗氧化能力的物质生成。因此,糖基化改性后的绿豆蛋白在抗氧化能力研究上具有一定的应用价值。

摘  要:
Mung bean protein isolate( MBPI) and dextran as raw material,MBPI-Dextran covalent compounds were prepared through the hot and humid. Through the determination of product of reducing power,DPPH radical scavenging capacity,super oxygen anion free radical( O_2~-·) clearance ability,hydroxyl free radical( ·OH) clearance ability,this research evaluated the effects of glycosylation reaction on MBPI antioxidant capacity. The results showed that the MBPI-Dextran conjugates had certain antioxidant capacity,especially compared to 80 ℃,antioxidant capacity of the product of the reaction under the condition of 90 ℃ significantly increased,which was related to the degree of maillard reaction,the maillard reaction under high temperature process was accelerated,prompted production more material with anti-oxidation ability. Therefore,MBPI-Dextran had certain application value on antioxidant capacity.
