摘　　要：以乙醇法制备的非晶颗粒态玉米淀粉、辛烯基琥珀酸酐为原料,研究辛烯基琥珀酸淀粉酯(SSOS)的合成工艺条件。探讨了反应时间、反应温度、碱用量、辛烯基琥珀酸酐、淀粉乳的浓度、水分含量对取代度(DS)和反应效率(RE)的影响。结果表明:在淀粉乳浓度为0.25g/mL,乙醇溶剂含水35%时,pH为8.5,反应温度为35℃时反应2h为最佳反应条件,得到取代度为0.0166。The technology condition of amorphous octenyl succinic anhydride （OSA） starches from amorphous corn in aqueous slurry systems was studied in this paper. The effects of reaction time, reaction temperature, alkali addition, OSA addition and starch concentration on the DS and RE of product were studied. Experiment results show： the suitable parameters for the preparation of OSA-starch from potato were determined as follows： reaction time 2 h, reaction temperature 35 ℃, pH of reaction system 8.5, concentration of starch slurry 0.25 g/mL, the degree of substitution is 0.0166.
