    • 摘要: 米渣是大米深加工的副产物,加工过程中因淀粉被利用而留下蛋白质,因而米渣中大米蛋白含量高。大部分米渣经干燥后主要用作饲料,为了使其米渣中的蛋白质得到进一步的开发和利用,探讨了米渣蛋白的提取工艺。近年来,超声技术广泛应用于样品的前处理和提取工艺,分析了超声波处理、碱性蛋白酶处理及超声协同蛋白酶作用对米渣蛋白提取率的影响。分析了料液比、加酶量、酶解时间、酶解温度和超声时间等因素对米渣蛋白提取率的影响。并在单因素试验的基础上,通过正交试验优化确定了米渣蛋白的最佳提取条件,即料液比1∶10,超声功率500 W,超声时间80 min,酶反应时间100 min,加酶量1650 U/g,酶解温度55°C。在此最优提取工艺下蛋白质提取率为82.80%。

    • 摘要: 为探究米渣蛋白对水溶液中镉的吸附效果及米渣对土壤中镉活性的钝化效果,该研究首先用米渣蛋白在水溶液中对镉进行吸附、用盐酸解吸,并用Langmuir、Freundlich等温吸附方程来拟合米渣蛋白在水溶液中对镉的吸附过程,用动力学方程研究米渣蛋白与镉结合的机理,并根据线性关系从准一级、准二级吸附动力学方程中筛选更接近吸附动力的拟合方程.其次,通过周期取样,用Tessier分步连续提取法测定并探究米渣对土壤中镉的钝化能力.研究结果表明:在不同初始质量分数的镉溶液中米渣对镉的最大吸附量13.28 mg/g,用盐酸解吸各初始质量分数下结合的镉,解吸率均达到90%以上.同时,Langmuir和Freundlich等温方程均能拟合米渣蛋白在水溶液中对镉的吸附过程,且R2达到0.99以上;准一级动力学、准二级动力学方程拟合结果是,拟合出的准二级动力学方程线性更好,米渣蛋白对镉的吸附动力更符合准二级动力学方程.土壤中镉钝化试验表明:加入米渣后,28 d内土壤中镉的钝化效果较好,可能是由于米渣中的蛋白改变了土壤中镉的存在状态并降低镉的活性所致.该研究结果为米渣的应用提供新的思路,可为其在废水除镉、镉污染土壤的修复等方面应用提供理论依据.
