摘要
以生马铃薯为原料,通过酶法脱支制备抗性淀粉。探讨耐高温α-淀粉酶用量和作用时间,以及普鲁兰酶用量、作用时间和作用温度等因素对制备抗性淀粉得率的影响。在单因素试验的基础上设计正交试验,确定最佳工艺条件:耐高温α-淀粉酶用量3 NU/g、作用时间30 min;普鲁兰酶用量4 NPUN/g、作用时间10 h、作用温度55℃。在此条件下,抗性淀粉得率为10.45%±0.03%。该试验结果为马铃薯抗性淀粉的制备和工艺优化提供参考。
Using potato starch as raw material,the resistant starch was prepared by enzymatic debranching.The yield of resistant starch was used as the index to study the influence of enzymolysis dosage,enzymolysis time and enzymolysis temperature.The optimum technological condition was analyzed by orthogonal test.The result showed the optimal process condition was as follows:the dosage ofα-amylase 3 NU/g,the enzymatic hydrolysis time 30 min;the dosage of pullulanase 4 NPUN/g,the enzymatic hydrolysis time 10 h,and the enzymatic hydrolysis temperature 55℃.Under this condition,the yield was 10.45%±0.03%.The reference for the preparation and optimization of resistant starch in potato was provided.
