【摘要】 研究喷雾干燥法制备高包埋率微胶囊化花青素的壁材组成以及工艺条件,结果表明:花青素∶壁材为20%、麦芽糊精∶β-环状糊精为3∶1、阿拉伯胶比例为10.0%、喷雾干燥的进口温度120℃、出口温度80℃时,花青素的微胶囊化效果最好、包埋率高,而且花青素微胶囊化后,其稳定性有显著提高。更多还原

【Abstract】 The composition of wall materials and the technology of spray-drying for the microencapsulated anthocyanins were studied. The optimum microencapsulation technologies of anthocyanins were that the ratio of anthocyanins and wall materials was 20%, the ratio of maltodextrin and β-cyclodextrin was 3∶1, the concent of gum acacia was 10%, inlet air temperature was 120℃ and outlet air temperature was 80℃.更多还原
