粉末油脂微胶囊的研究

Research on powder oil microcapsules

主要论述了以变性淀粉和玉米醇溶蛋白为壁材,葵花籽油为芯材利用喷雾干燥法制备微胶囊粉末油脂的最佳配比以及粉末油脂中包裹的葵花籽油的性质。使用STABI-AT109变性淀粉时,制备粉末油脂的最佳配比为变性淀粉占2.5%,玉米醇溶蛋白占0.11%,乳化剂占1%,乙醇占40%葵花籽油占1%。该粉末油脂的包埋率可以达到76.52%。使用PREGEL-AT0700A变性淀粉时,制备粉末油脂的最佳配比为变性淀粉占2%,玉米醇溶蛋白占0.11%,乳化剂占1%,乙醇占30%,葵花籽油占1%。该粉末油脂的包埋率可以达到79.41%。

This research mainly elaborated take the modified starch and the Zein as the wall material,sunflower oil as the core material prepared by use of spray-dried powder microcapsules the best ratio of fats and oils powder wrapped in the nature of the sunflower seed oil.Study found that when using STABI-A T109 modified starch,fat powder of the best ratio of modified starch accounted for 2.5%,Zein of 0.11%,one percent of the emulsifier,ethanol accounted for 40%of sunflower seed oil 1%.The powder was embedded in the oil can be reached 76.52%.When using PREGEL-AT 0700A modified starch,the preparation powdered oil's best allocated proportion accounts for 2% for the modified starch,the corn Zein accounts for 0.11%,the emulsifier accounts for 1%,the ethyl alcohol accounts for 30%,the sunflower seed oil accounts for 1%.This powdered oil's embedding rate may achieve 79.41%.
