摘要: 本实验分别以β-环糊精(β-cyclodextrin,β-CD)、β-CD+麦芽糊精(maltodextrin,MD)、辛烯基琥珀酸淀粉钠(octenylsuccinate starch sodium,OSS)、酪蛋白为壁材,以香草兰精油为芯材,采用喷雾干燥制备具有缓释性的微胶囊。以产率、包埋率、溶解性、缓释性、乳化液稳定性等为评定指标,对比分析4?种壁材的包埋效果。结果表明:以OSS为壁材的香草兰精油微胶囊(VO-OSS)产率最高,为84.17%,包埋率为78.04%,溶解度和乳状液稳定性分别为96.31%和97.82%,具有良好的冲调性、溶解性和乳化性。MD与β-CD复配壁材的香草兰精油微胶囊(VO-MD)产率和包埋率最低,分别为71.37%和61.18%。在粒径方面,VO-OSS粒径最小,为190?nm。扫描电子显微镜观察结果显示,VO-OSS表面结构光滑、呈球状。VO-OSS在60?℃贮存10?d后,香兰素的保留率为54.62%,表明缓释性高于其他3?种微胶囊。综合所有指标,对比其他3?种微胶囊产品,OSS是制备香草兰精油微胶囊的最佳壁材。

Abstract: Sustained-release microcapsules were prepared by spray-drying using β-cyclodextrin (β-CD), β-CD + maltodextrin (MD), octenylsuccinate starch sodium (OSS) or casein (CS) as wall material and vanilla essential oil as core material. A comparative evaluation of four wall materials was made based on microcapsule yield, encapsulation efficiency, solubility, releasing rate, and emulsion stability. The results showed that vanilla essential oil microcapsules with OSS as wall material (VO-OSS) had the highest yield (84.17%) with an encapsulation efficiency of 78.04%, and the reconstitution properties, solubility (96.31%) and emulsion stability (97.82%) were good. vanilla essential oil microcapsules with β-CD + MD as wall material (VO-MD) showed the lowest yield (71.37%) and encapsulation efficiency (61.18%). VO-OSS showed the smallest particle size of 190 nm. Scanning electron microscopic (SEM) observation showed that VO-OSS had a smooth spherical appearance. After 10 days of storage at 60 ℃, VO-OSS remained 54.62% vanillin, which indicated that the sustained-release property of VO-OSS was higher than three other kinds of microcapsules. In conclusion, OSS is the best wall material for vanilla oil microcapsules based on all indicators.
