摘　　要：以裸燕麦粉和玉米淀粉为原料,添加苦荞黄酮提取物,采用DSE-30双螺杆挤压膨化机生产挤压膨化产品,通过清除DPPH、羟基自由基和三价铁还原能力的测定,考察产品膨化前后与添加苦荞黄酮提取物的膨化产品的体外抗氧化能力,通过高脂动物模型考察产品降血脂功效。结果表明,添加苦荞黄酮提取物的燕麦挤压膨化产品的抗氧化活性得到明显提高,对小鼠的糖脂代谢紊乱具有更好的改善作用。该技术可用于强化抗氧化能力和调节血脂的膨化食品或食品配料的生产。Naked oat flour and corn starch were used as raw materials, flavonoid in buckwheat were added, and extruded products were produced by DSE-30 twin-screw extruder. The antioxidant activities in vitro of the extruded products before and after extrusion and those of the extruded products with flavones in buckwheat were investigated by measuring DPPH scavenging capacity, hydroxyl radical scavenging capacity and trivalent iron reducing capacity. The results showed that the antioxidant activity of the extruded oats with flavones in buckwheat was significantly improved, and the glucose and lipid metabolism disorder in mice was better improved. This technology could be used to enhance antioxidant capacity and production of expanded foods or ingredients that regulate blood lipids.
