三种壁材组合方式茶籽油微胶囊产品的研究

本研究以大豆分离蛋白(SPI)、阿拉伯胶(AG)、辛烯基琥珀酸淀粉酯(HI-CAP100)、麦芽糊精(MD)为壁材,茶籽油为芯材,通过简单复配组合方式进行组合。利用喷雾干燥技术,制得微胶囊产品,以乳液稳定性、乳液流变特性、包埋率、水分含量、冲调性、粒径等感官特征为评价指标,结果表明：在麦芽糊精添加量为总壁材质量的25%时,SPI/AG质量比为1:1,乳状液稳定性指数最高为94.55%；乳液流变性特性呈现剪切变稀现象；微胶囊产品具有较高的包埋率为89.58%；冲调性较好；白色粉末；含水量为2.62%；颗粒形态完整、表面光滑、大小均匀；粒径分布比较集中。是制备茶籽油微胶囊产品较为理想的壁材方式。最终确定最佳茶籽油微胶囊壁材组合方式：麦芽糊精+大豆分离蛋白+阿拉伯胶。

Study on three combinations ofall materials for tea seed oil microcapsule products

In this study, soybean protein isolate (SPI), gum arabic (AG), starch octenyl succinate (HI-CAP100), and maltodextrin (MD) were used as the wall materials, and tea seed oil was used as the core material. Combining in combination. Using spray drying technology to produce microcapsule products, the sensory characteristics of emulsion stability, emulsion rheological properties, embedding rate, moisture content, refinability, particle size and other sensory characteristics are used as evaluation indicators. The results show that: the amount of maltodextrin
