以湘晚籼13和星2号两种稻谷品种为原料,采用糙米快速发芽技术,研究糙米发芽过程中抗氧化活性变化,其中抗氧化活性综合了目前广泛采用的六种方法,分别为DPPH自由基清除、铁离子还原力、羟基自由基清除、ORAC（氧化自由基吸收能力）荧光法、总抗氧化能力测定（ABTS）法、抑制脂质过氧化能力。结果表明,随着糙米的发芽,其体内的抗氧化活性物质在发生改变,此变化过程中会达到一个最佳状态,得出发芽14 h的湘晚籼13糙米和发芽12 h的星2号糙米抗氧化活性最好。

With 13 Xiang Late Indica and Star 2 two rice varieties as material,using brown rice quick germination technology,the change of antioxidant activity in vitro of brown rice gemination was studied.The antioxidant activity was a combination of six kinds of methods,including DPPH radical scavenging,iron reducing power,hydroxyl radical scavenging,ORAC（oxide free radical absorptive capacity） fluorescence method, determination of total antioxidant capacity（ABTS） method and ability to inhibit lipid peroxidation. The results showed that with brown r...
