中文摘要：

以小麦A淀粉为材料，采用乙醇-碱处理法制备颗粒状冷水可溶淀粉，在系统分析乙醇体积分数、碱浓度、反应温度、反应时间等因素对颗粒状冷水可溶淀粉溶解度影响的基础上，对其制备工艺条件进行了优化。结果表明：采用乙醇-碱法制备小麦颗粒状冷水可溶淀粉，乙醇体积分数和反应时间对产物溶解度的影响显著；小麦颗粒状冷水可溶淀粉的适宜制备条件为反应温度65℃，乙醇体积分数80％，反应时间为80min，碱浓度10g／100ml，其溶解度可达81．44％。

英文摘要：

The effects of ethanol concentration, alkaline concentration, reaction temperature, reaction time, and other factors to the solubility of granular cold-water-soluble starch were analyzed, and the preparation technology conditions were also optimized. The results showed that by using ethanol-alkali method to prepare cold-water-soluble starch, the impact of ethanol concentration and reaction time on the solubility of wheat granular cold-water-soluble starch was significant; the appropriate preparation conditions for wheat coldwater-soluble starch was on the reaction temperature of 65℃, ethanol concentration of 80 ml/100 ml, reaction time of 80 min, alkali concentration of 10 g/100 ml, under this condition the solubility of the product was up to 81.44%.
