| 摘 要： | 对多孔淀粉进行磷酸酯化改性处理,使其既具有磷酸酯淀粉的特性,又具有多孔淀粉的吸附性质.以自制的大米多孔淀粉为原料,三聚磷酸钠为酯化剂,通过单因素试验和响应面试验,经SAS软件分析,确定了制备大米多孔磷酸酯淀粉的最佳条件,并对其进行验证.结果表明,磷酸盐用量4％、温度150℃、时间150 min、pH 6是合成大米多孔磷酸酯的最佳工艺条件.此法制得的大米多孔磷酸酯淀粉取代度为0.09,并且通过SEM观察验证它仍然具有大米多孔淀粉的完整结构.

| Abstract: | The porous starch was treated by phosphoric acid-esterified modification,so that it might have both the characteristics of phosphate starch and the adsorption properties of porous starch.With raw material of self-made porous rice starch and the esterifying agent of sodium tripolyhosphate,the single factor test and response surface analysis were carried out in this paper.As analyzed by SAS software,the optimum conditions for preparation of porous rice phosphate starch were determined and verified accordingly... |
