乳清分离蛋白-葡聚糖接枝物Pickering乳液的 稳定性研究Stability of whey protein isolate-dextran conjugate Pickering emulsion
为提高蛋白基Pickering乳液稳定性,采用美拉德反应制备乳清分离蛋白(WPI)-葡聚糖(Dex)接枝物,然后利用该接枝物制得蛋白基固体颗粒,再与中链甘油三酯制备Pickering乳液,考察WPI-Dex接枝物对蛋白基固体颗粒乳化活性、乳化稳定性和蛋白基Pickering乳液乳析指数的影响,以及Pickering乳液在不同pH、加热温度、贮藏时间下粒径的变化。结果表明:扫描电镜观察到共价接枝Dex将WPI形貌结构由球状转变为片状,十二烷基硫酸钠-聚丙烯酰胺凝胶电泳证实干法美拉德反应成功制备了WPI-Dex接枝物;与WPI相比,WPI-Dex接枝物的乳化活性和乳化稳定性分别增加了57.8%和1...
