摘　　要：用醇溶剂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,并用响应面优化工艺条件,最后对产品的吸油性质和机理进行了初步的研究。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,得到的新产品的吸油性质良好。The processing condition of octenyl succinic anhydride （SSOS） starches from corn in solvent systems was studied in this paper. Response surface analysis was used to optimize the reaction conditions. And the oil-absorption property and mechanism of the starch were studied. Results showed that the suitable parameters for the preparation of OSA - starch fi＇om potato were as follows： reaction time 2 h, reaction temperature 35 ℃, pH of reaction system 8.5, and concentration of starch slurry 0.25 g/mL. Under those conditions, the DS was 0.0166 and the achieved product showed good oil-absorption property.
