本研究的目的是通过辛烯基琥珀酸酐 (OSA) 淀粉、乳清分离蛋白 (WPI) 和菊糖 (IN) 底物构建具有高载油量的微胶囊系统，为包封甘油二酯油提供一种新方法。具体来说，本研究通过比较二元壁系统 OSA-IN、WPI-IN 和三元壁系统 WPI-OSA (1:9, 5: 5, 9:1)-IN 用于甘油二酯油。结果发现，与 OSA-IN 微胶囊相比，WPI-OSA (5:5)-IN 显着提高了微胶囊的水溶性 (86.11 %)，WPI的加入使微胶囊表面更加光滑，增加了微胶囊的热稳定性和溶解度；与 WPI-IN 相比，OSA 的添加增强了微胶囊的润湿性。此外，WPI-OSA (5:5)-IN 微胶囊具有最高的包封率 (96.03 %)、重构后的高乳液稳定性以及 28 天后的最小液滴尺寸 (212.83 nm)。因此，WPI-OSA-IN复合体系适用于制备高载油量微胶囊体系，具有优异的复水能力，可扩大甘油二酯油的应用范围。和 28 天后最小的液滴尺寸 (212.83 nm)。因此，WPI-OSA-IN复合体系适用于制备高载油量微胶囊体系，具有优异的复水能力，可扩大甘油二酯油的应用范围。和 28 天后最小的液滴尺寸 (212.83 nm)。因此，WPI-OSA-IN复合体系适用于制备高载油量微胶囊体系，具有优异的复水能力，可扩大甘油二酯油的应用范围。

Constitution and reconstitution of microcapsules with high diacylglycerol oil loading capacity based on whey protein isolate / octenyl succinic anhydride starch/ inulin matrix

The aim of this study was to constitute microcapsule systems with high oil loading capacity by octenyl succinic anhydride (OSA) starch, whey protein isolate (WPI) and inulin (IN) substrates to provide a new method for encapsulating diacylglycerol oil. Specifically, this study characterizes the physicochemical properties and reconstitution capacity of highly oil loading diacylglycerol microcapsules by comparing the wall encapsulation capacity of the binary wall system OSA-IN, WPI-IN and the ternary wall system WPI-OSA (1:9, 5:5, 9:1)-IN for diacylglycerol oil. It was found that WPI-OSA (5:5)-IN significantly improved the water solubility of microcapsules (86.11 %) compared to OSA-IN microcapsules, and the addition of WPI made the surface of microcapsules smoother and increased the thermal stability and solubility of microcapsules; the addition of OSA enhanced the wettability of microcapsules compared to WPI-IN. In addition, WPI-OSA (5:5)-IN microcapsules have the highest encapsulation efficiency (96.03 %), high emulsion stability after reconstitution, and the smallest droplet size (212.83 nm) after 28 d. Therefore, the WPI-OSA-IN composite system is suitable for the production of highly oil-loaded microencapsulated systems with excellent reconstitution ability to expand the application of diacylglycerol oil.
