Abstract:

Octenylsuccinate sucrose ester was synthesized via esterification with sucrose and octenylsuccinate as raw materials. IR spectral analysis revealed that the C = O and C = C vibration absorption peaks appeared at 1724.05 and 1569.57 cm-1, respectively. A new microencapsulation system was established and an embedding rate of 96.2% was obtained by replacing sodium caseinate with octenylsuccinate sucrose ester in the microencapsulation. It is illustrated that octenylsuccinate sucrose este has good surface activity.

Key words: octenylsuccinic anhydride, sucrose, infrared spectrum, microencapsulation
