酶法提高大豆糖蜜抗氧化活性及其机理（Enhanced Antioxidant Activity of Soybean Molasses Using Cellulase）
大豆糖蜜 抗氧化活性 生物酶解
2009/5/22
为提高大豆糖蜜的抗氧化活性，将大豆糖蜜溶液与纤维素酶溶解于pH值5.0的50mmol/L Tris-HCl 缓冲液中，于50℃保温30min。对比了酶解前后大豆糖蜜的清除DPPH自由基能力和还原力，并分析了异黄酮的组成差异。结果表明：达到50% DPPH自由基清除率，需未处理样品17.15g/L，而处理样品仅为9.19g/L。在相同的质量浓度下，处理后的大豆糖蜜还原力要高于未被处理的大豆糖蜜。纤维...
