摘  要:
以玉米淀粉为原料,通过正交试验对半干法制备磷酸单酯淀粉的工艺进行优化。获得较优方案为多聚磷酸钠加量9%、尿素2%、pH5.0、150℃条件下反应2h,取代度最高可达0.0516。正交试验结果稳定,重复性好。温度提高至180℃进行反应可获得较高取代度,但产品色泽需改善;淀粉水分15%左右时有利于酯化反应进行,且产品色泽较好。

摘  要:
The semi-dry preparation of starch phosphate monoesters from corn starch was optimized using orthogonal array design. The optimal reaction system was found to consist of 9% sodium polyphosphate and 2% urea at pH 5.0 and the reaction was allowed to proceed for 2 h at 150 ℃,and the degree of substitute was up to 0.0516 under these conditions. The established process was stable and repeatable. A higher degree of substitute was obtained at a higher reaction temperature of 180 ℃,but the color of the obtained product needed to be improved. Starch containing 15% moisture was beneficial for the reaction,producing better product color.
