摘要
以玉米淀粉为原料,采用乙醇-碱液为溶剂,微波处理法制备冷水可溶性玉米淀粉,通过各单因素试验和L9(34)正交试验,确定了冷水可溶性玉米淀粉的最佳制备工艺条件。结果表明,当料液比1:1,乙醇体积分数为80%,碱液加入量为11 g/100 mL,微波处理时间3 min,微波功率为400 W时,制得的冷水可溶性玉米淀粉的溶解度达到最大为59.12%。
The study was on the preparation technology of cold-water-soluble corn starch by microwave treatment, used corn starch as raw material and ethanol-lye solution as the Extraction solvent. Single factor experiments and orthogonal test L9（3^4） were used to the experiment. The results showed that the best optimum conditions of preparation were material liquid ratio （g： ml） 1：1, ethanol concentration is 80%, the lye adding amount 11g/100mL, the microwave processing time 3rain, microwave power 400W. The best Solubility of cold-water-soluble corn starch was 59.12%.
