A technology of self-emulsification coacervation to prepare starch sodium octenyl succinate (SSOS) microcapsules consisting of evening primrose oil (EPO) as a core material has been illustrated in this report. The optimal microencapsulation conditions has been investigated and the morphology of the microcapsules has been observed by Optical microscope. The results show that the optimized microencapsulation condition is core-wall ratio 2 g/g , DS 0.050, coacervating agent 0.8 mL/mL emulsion, with the cross-linker 0.04 g/g SSOS, stirring speed 700 rpm for emulsification, and 350 rpm for coacervation. Meanwhile,the protective effect experiments via aeration method indicate that the increment of peroxide value (POV) of entrapped EPO is only 5.68% compared to unencapsulated EPO after aeration for 48 h, which shows good protection performance of SSOS microcapsules to entrapped substances.
