摘　　要：以玉米淀粉为原料,采用乙醇-碱法制备颗粒状冷水可溶性淀粉。研究乙醇体积分数、固液比、碱量、微波处理时间对颗粒状冷水可溶性淀粉溶解度的影响。通过单因素试验和正交试验得到最佳条件,即NaOH 30 mL,固液比1∶15,乙醇体积分数80%,微波处理时间4 min,此条件下制备的颗粒状冷水可溶性淀粉溶解度高达83.23%。In the present study corn starch as raw material, granular cold-water-soluble starches are prepared with ethanol-alkali. The offects of the ethanol concentration, solid-liquid ratio, alkali, and microwave treatment time on the solubility of granular cold-water-soluble starch are studied. Through the single factor experiment and the orthogonal experiment to get the best conditions, that is sodium hydroxide 30 mL, solid-liquid ratio 1 ： 15, ethanol content 80%, microwave treatment 4 rain, prepared under these conditions, the solubility of granular cold-water-soluble starches np to 83.23%.
