51.05%。 Star aniseed oil is composed of volatile spicery components and it is easy to be oxidized, which limits its storage and application. Microcapsules of star aniseed oil are prepared，it can effectively restrain the volatilization and oxidation of the star aniseed oil，the storage stability can be improved. The production technology of star aniseed oil microcapsule with chitosan and alginate was studied in this paper. The results showed that the optimum conditions for microencapsulation were established as follows：the alginate concentration as 3.0%，chitosan concentration as 1.0%，calcium chloride concentration as 2.0%，the ratio of wall-material and core-material was 1∶3，pH was 5.0.
