摘要:

以蔗糖和辛烯基琥珀酸酐为原料经酯化反应制备辛烯基琥珀酸蔗糖酯。经红外光谱扫描后,在1729.05cm-1处有C = O 伸缩振动吸收峰,在1566.92cm-1 处有C = C 伸缩振动吸收峰。将制备的产品代替酪朊钠酸应用到油脂微胶囊化中,建立新的微胶囊化乳化体系,油脂的包埋率达到了96.2%,取得较好的效果,说明辛烯基琥珀酸蔗糖酯具有好的表面活性。

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
