ABSTRACT
OBJECTIVE: To prepare Zingiber officinale oil microcapsules and to evaluate its quality. METHODS: Z. officinale oil microcapsules were prepared by spray drying method with sodium starch octenyl succinate as capsule material. The preparation technology was optimized by orthogonal test with mixing temperature of capsule material and capsule core, mass ratio of capsule material and capsule core, stirring speed as factors, using encapsulation efficiency as index. The drug loading, encapsulation efficiency, appearance, particle size distribution and stability of lightheat and humidity (using iodine value and peroxide value as indexes) were evaluated. RESULTS: The optimal preparation technology of Z. officinale oil microcapsules was that the mixing temperature of capsule material and core was 60 ℃; mass ratio of capsule material and capsule core was 10 ∶ 1; stirring speed was 12 000 r/min. Average drug-loading amount and encapsulation efficiency of Z. officinale oil microcapsules prepared by optimal technology were 17.97% and 73.57% (n=3). The morphology of Z. officinale oil microcapsules was round, smooth, non-sticky and uniform in size distribution. The average diameter of microcapsules was (6.30±0.27) μm. Under lightheat and humidity conditions, the iodine value and peroxide value of Z. officinale oil microcapsules changed slightly. CONCLUSIONS: The optimal preparation technology of Z. officinale oil microcapsules is simple and reproducible. The prepared microcapsules have good encapsulation efficiency, high drug loading amount and good stability.
