摘　　要：为了研究菊糖的十二烯基琥珀酸酐改性工艺条件,以菊糖、硼氢化钠及十二烯基琥珀酸酐用量、反应时间、反应pH以及反应温度为影响因素,以十二烯基琥珀酸酐的取代度为考察指标,运用Plackett-Burman设计筛选出3个对菊糖的十二烯基琥珀酸酐取代度影响显著因素,即十二烯基琥珀酸酐用量、反应pH和反应时间。用响应面分析实验优化十二烯基琥珀酸菊糖酯改性工艺。十二烯基琥珀酸菊糖酯改性最优工艺:菊糖4g,硼氢化钠0.015g,十二烯基琥珀酸酐0.94g,反应时间为6.8h,反应pH8.5,反应温度35℃,菊糖的十二烯基琥珀酸酐取代度为0.0140±3.33E-05。In order to study optimum conditions for dodecenly succinic anhydride-modified inulin,effects of the amount of inulin,the dosage of sodium borohydride and dodecenly succinic anhydride （DDSA）,pH,time and temperature used on the degree of substitution of dodecenly succinic anhydride - modified inulin were investigated. Plackett -Burman was adopted to screen out the important factors,which were the dosage of dodecenly succinic anhydride,pH and time used. The optimum reaction conditions were obtained by response surface analysis：inulin 4g,sodium borohydride 0.015g,dodecenly succinic anhydride 0.94g,time 6.8h,pH8.5, temperature 35℃ ,and the degree of substitution of dodecenly succinic anhydride-modified inulin is 0.0140 ± 3.33E-05.
