Preparation of Sesame Oil Microcapsules by Complex Coacervation

Using gelatin and chitosan as wall material and the small grinding sesame oil as the core material,gelatin-chitosan microcapsules was prepared by complex coacervation.Results showed the best ratio of gelatin to chitosan,emulsion speed,substrate concentration,pH value the system concentration,and cross-linking time were 4:1,5000～7000 r/min,1%～2%,6.0～6.4 and 60～90 minutes,respecively.
