摘要: 以普通玉米淀粉为原料,通过正交试验确定了压热法和酸解法生产抗性淀粉的最佳工艺。研究了各因素对抗性淀粉产率的影响。压热法最佳工艺:20%淀粉乳于120℃加热75min,产率为23.5%;酸解法最佳工艺:30%淀粉乳经2%HCl水解1h后沸水浴1.5h,抗性淀粉得率为27.24%。综合成本及RS产率得出,酸解法优于传统压热法。

Abstract: By orthogonal test the best technologies for producing resistant starch with autoclave method and acid hydrolysis method were determined using ordinary corn starch as raw material respectively. The effects of various processing parameters on resistant starch productivity were studied. The best autoclave method technology parameters are: 20% starch being heated for 75 min at 120 ℃, and the productivity is 23.5%; The best acid hydrolysis method technology parameters are: 30% starch being heated by boiling water bath for 1.5 h after 2% HCl hydrolysis for 1 h, and the productivity is 27.24%. The acid hydrolysis method is better in terms of cost and productivity.

Key words: corn resistant starch, autoclave method, acid hydrolysis method
