研究了膜乳化法制备莱菔硫烷微胶囊的工艺，采用乙酸乙酯作为有机溶剂相，玉米油与乙基纤维素的质量比为6∶4，乙基纤维素浓度5%时，制得的微胶囊对莱菔硫烷的包埋率最高。同时分析了减压蒸发、常温蒸发和溶剂扩散3种溶剂去除方法对所制备微胶囊包埋率和平均粒径的影响，结果表明，减压蒸发法有更好的包埋率，且速度快、耗时短，平均粒径适合，制得的莱菔硫烷微胶囊分散性能好、表面光滑、流动性好。

Sulforaphane microcapsules were prepared by membrane emulsification method under optimal condition. Ethyl acetate was organic solvent phase , the mass ratio of corn oil and ethyl cellulose ethyl cellulose was 6∶4, ethyl cellulose concentration was 5%. The encapsulation efficiency (EE)of the prepared microcapsules was the highest. At the same time, the solvent removal effects to EE of the prepared microcapsules and the average particle size of the vacuum evaporation , room temperature evaporation and solvent diffusion method were evaluated. The results showed that EE of vacuum evaporation method had better than that of other two methods, and the prepared speed was quick, time was short, the average particle size was suitable. The prepared sulforaphane microcapsules had good dispersion performance , smooth surface and good fluidity.
