| 单因素实验结果表明：MRPs清除DPPH·自由基的能力随反应温度和反应时间的增加而增加，其清除·OH自由基的能力随反应时间的增加而减小；其还原能力和清除·OH自由基随反应时间和反应温度的增加先增加后减小。正交试验结果表明：在115℃、浓度0.5 mg/ml、反应时间90min时制备的MRPs其清除DPPH·的能力最大为88.73%；在浓度0.6 mg/ml，反应时间40min，温度65℃时MRPs的还原能力最大为A700nm=1.684；在反应时间10min，浓度0.6 mg/ml，温度65℃MRPs的清除·OH的能力最大为98.72%。不同的反应条件下制备的MRPs均表现出了很高的抗氧化活性，相同浓度的MRPs比Vc和TBHQ抗氧化效果更好，但其抗氧化能力并不完全依赖于产物的褐变程度。 |

| The results of the single factor experiments showed that MRPs’ ability to scavenge the DPPH free radicals increased as the the reaction temperature and reaction time did, but its ability to scavenge the OH free radicals decreased with the increase of the reaction time. Meanwhile, the reductive ability of MRPs and its ability of scavenging the OH free radicals first increased and then decreased as a result of the increase of the reaction temperature and reaction time. The results of the orthogonal experiments indicated that the highest ability of MRPs, which was prepared with the concentration of 0.5 mg / ml for 90 min at 115℃, scavenging DPPH was 88.73%, its highest reductive ability prepared with the concentration of 0.6 mg / ml for 40 min at 65℃ was A700nm=1.684, and its highest ability to scavenge OH with the concentration of 0.6 mg / ml for 10 min at 65℃ was 98.72%. These results presented that there was always a high antioxidant activity of MRPs in spite of different reaction conditions. With the same concentration, MRPs had got better antioxidant effect than that of Vc and TBHQ. Nevertheless, the antioxidant capacity of MRPs did not entitely depend on the browning degree of the products. |
