超声波处理对小麦胚芽球蛋白理化和功能性质的影响(Effect of Ultrasound Treatment on Physicochemical and Functional Properties of Wheat Germ Globulin)
小麦胚芽球蛋白 理化性质 功能性质
2009/9/11
采用超声波处理小麦胚芽球蛋白以提高其功能性质。研究了超声波处理对小麦胚芽球蛋白理化和功能性质的影响。结果表明:经超声波处理后,小麦胚芽球蛋白的巯基和二硫键含量、紫外光谱和荧光光谱均发生了显著的变化。随着超声波功率的增加,小麦胚芽球蛋白的疏水性、起泡性、起泡稳定性、乳化性和乳化稳定性都降低;当超声波功率大于900?W时,由于小麦胚芽球蛋白重新伸展,疏水基团暴露增多,引起疏水性、起泡性、起泡稳定性、乳...
