淀粉基多孔高吸水树脂致孔剂对吸液速率影响（Effect of Porosity Generators on Absorbency Rate Starch-based Superabsorbent）
高吸水树脂 致孔剂 吸液速率
2009/11/3
研究了淀粉基多孔高吸水树脂的合成及其吸液性质，比较了不同致孔剂如丙酮、碳酸氢钠、蔗糖对树脂吸液速率的影响。结果表明，添加致孔剂能有效提高树脂的吸液速率，碳酸氢钠具有较好的致孔效果。扫描电镜分析证明，合成的高吸水树脂具有疏松的多孔结构，它是提高高吸水树脂吸液速率的主要原因。
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...
微波频率和温度对食用植物油介电特性的影响（Effect of Frequency and Temperature on Microwave Dielectric Properties of Edible Vegetable）
食用植物油 介电特性 温度
2009/9/11
采用同轴探头技术研究了20～90℃、200～4500MHz内菜籽油、大豆油、花生油、玉米油、调和油的介电特性，分析了介电参数值随频率和温度变化的原因。结果表明：同频率下，菜籽油具有最大的相对介电常数和最小的介质损耗因数，而玉米油则相反。在500～4000MHz间，介电参数与食用油中的饱和与不饱和脂肪酸含量间具有较好的线性相关性。相对介电常数随温度升高线性减小，但介质损耗因数则线性增大。菜籽油的介电...
