微波辅助Osborne法提取米糠谷蛋白及对其性质的影响Microwave-assisted Osborne extraction of rice bran gluten and its properties
米糠中蛋白质含量丰富,蛋白的必需氨基酸组成也比较完整,是一种优良的蛋白资源,因其组成成分复杂,难于提取。为了更加有效地提取米糠谷蛋白,采用微波辅助Osborne法提取米糠谷蛋白,通过单因素试验研究微波功率、微波时间、微波温度对米糠谷蛋白提取率的影响,在此基础上采用正交试验确定最优提取条件,同时研究了微波处理对米糠谷蛋白结构和功能性质的影响。结果表明:在微波功率800 W、微波时间15 min、微波温度40 ℃的条件下,米糠谷蛋白提取率为73.1%。微波处理后,米糠谷蛋白的α-螺旋和β-转角向β-折叠转移,β-折叠含量明显提高。经过微波处理后,米糠谷蛋白的溶解性提高了8.12百分点,持水性提高了...
