摘要
以玉米淀粉为原料,以植酸钠为改性剂,研究了植酸淀粉的干法制备工艺,探索了pH值、植酸钠用量、植酸钠质量分数、反应温度和反应时间等因素对产品取代度的影响。研究结果表明,植酸淀粉的最佳制备工艺条件为:植酸钠用量6%,植酸钠质量分数15%,反应温度140℃,反应时间2h,pH值为8。
Starch phytate has been prepared by dry process preparation, corn starch and sodium phytate as primal materials. The effects of pH value, the amount and concentration of sodium phytate, temperature and reaction time on the substitutions of the products were studied by doing a serial of experiments. The-results showed that the optimal reaction conditions of preparing starch phytate using dry process were the sodium phytate amount 6%, the concentration of starch phytate 15%, reaction temperature 140℃, reaction time 2h, pH 8.
