摘要: 采用酸变性和沸水浴的方法,对甘薯淀粉进行处理,以抗性淀粉得率作为评价指标,通过正交试验和响应面分析,得出甘薯抗性淀粉最优制备条件为:酸解时间为1.44h、盐酸用量为1.28%、水与淀粉的比为8.32:1、沸水浴时间为3.08h;抗性淀粉得率13.91%。

Abstract: Sweet potato resistant starch was prepared by acid-modifying and heat-moisture treatments. A response surface analysis (RSA) was conducted and resulted in the following optimum conditions of preparing sweet potato resistant starch, sach as acid-modification time 1.44h, ratio between water and sweet potato starch 8.32:1, heat-moisture time 3.08h, and HCl 1.28%.The outputof resistant starch was 13.91%.
