以糯玉米淀粉、早籼米淀粉、小麦淀粉和马铃薯淀粉为原料,采用湿法工艺制备辛烯基琥珀酸淀粉酯(starch sodium octenyl succinate,SSOS),并对所制备不同取代度产品的理化性质进行了研究.粘度速测仪分析表明,几种淀粉经辛烯基琥珀酸酐改性之后,具有较原淀粉高的峰值粘度.扫描电镜观察结果显示,水相体系中制备辛烯基琥珀酸淀粉酯使淀粉颗粒表面产生一些孔洞,酯化反应可能首先发生在淀粉颗粒的表面.4种原料淀粉经过酯化改性之后,乳化效果明显提高,而且乳化效果:早籼米SSOS>糯玉米SSOS>小麦SSOS>马铃薯SSOS.

This paper worked on the preparation of octenyl succinic anhydride (OSA) modified star-ches from waxy corn starch,early indica rice starch,wheat starch,and potato starch in aqueous slurry systems.The physicochemical properties of native and OSA modified starches were also investigated.Rapid visco analyzer profiles showed that OSA starches had higher peak viscosities than their native counterparts.Scanning electron microscope results indicated that some pores formed on the surface of starch granules after the first attacking of OSA groups.After OSA modification,the emulsion properties of four native starches increased greatly,and emulsion effect variation- of the four starches is in the following order:early indiea rice starch > waxy corn starch > wheat starch > potato starch,respectively.
