| Sea buckthorn seed oil microcapsules were prepared by spray drying technology under the pre-optimized conditions. The properties of sea buckthorn seed oil microcapsules, such as basic indexes, particle size distribution, microscopic morphology, the content of lipid accompanying substances, and fatty acid composition under accelerated storage conditions were studied so as to comprehensively evaluate the quality of sea buckthorn seed oil microcapsules. In addition, sea buckthorn seed oil microcapsules were applied to prepare chewable tablets, and the quality of chewable tablets were determined. The results showed that the water content of sea buckthorn seed oil microcapsules was 3.43%, the solubility was 92.22%, the angle of repose was 36.34°, the surface oil content was 1.32%, and the embedding rate was 97.32%. The particle size distribution was uniform, and the structure was complete and no cracking or hole phenomenon. After microencapsulation, the lipid accompanying substances were well remained. The fatty acid composition changed slightly under accelerated storage for 30 d. The color, tissue state and texture of the chewable tablets produced with sea buckthorn seed oil microcapsules were good and the taste was moderate. |
