摘要
本实验以玉米淀粉为原料,用湿热处理的方法对淀粉进行改性。用均匀设计试验方法确定最佳工艺条件。结果显示:温度和时间为影响最大的因素,以盐酸水解淀粉的水解率为指标,用3mol/L的盐酸溶液50ml,在45℃下反应10h;确定最佳工艺条件为:湿度14%,温度120℃,时间4h。此处理条件的变性淀粉对盐酸水解率的最大值为14.39%。
Heat-moisture treatment for cornstarch was used in this experiment. Modified cornstarches were hydrolyzed by hydrochloric acid, then percentage of hydrolysis of modified cornstarches was measured in order to get the best modified cornstarch. With uniform design, the most important influence factors in this test were choose. Results were followed： the degree of humidity 14%, the temperature 120℃, and time 4 h. On these conditions, the maximum hydrolysis percentage for modified cornstarch is 14.39%.
