基于微通道乳化技术的单分散大豆分离蛋白乳状液制备Preparation of Monodispersed Emulsion Stabilized by Isolated Soybean Protein Based on Microchannel Emulsification Technique
单分散 大豆分离蛋白 微通道乳化技术
2009/8/11
以大豆分离蛋白为乳化剂，采用微通道乳化技术制备单分散乳状液，研究乳状液粒子的成粒特性。结果表明：当大豆分离蛋白的pH值为6～8时，微通道乳化技术能够成功制备单分散的乳状液，但是随着pH值的增大，粒子的单分散性增强。当pH值为7时，单分散乳状液的粒子平均粒径为43.4μm，变异系数为4.3％。大豆分离蛋白的微通道乳化特性与其等电点相关，当pH值低于等电点时，蛋白质分子的正电性与微通道板的负电性相互作...
