A delivery system can enhance the solubility， stability and bioavailability of bioactive substances by encapsulating them and thus make it convenient application in the food， medicine， cosmetics and other fields. Emulsification solvent evaporation is a common method to prepare delivery carriers of active substances， its characteristics including use of mild conditions， ease of use and scale-up， lower residual solvent and so on. After introduction of emulsification solvent evaporation method， this paper summarizes the influence of material selection and preparation process on the delivery carriers， as well as the research progress on the application of this method in the delivery system， in order to promote further research and practical application of emulsification solvent evaporation method.
