摘　　要：以纤维素酶作为水解酶,采用水酶法从青稞米籽粒中提取淀粉.通过单因素试验和正交试验,得到青稞淀粉的最佳提取条件:加酶量20 EGU/g、酶解时间8 h、酶解温度45℃、酶解pH值6.5.在最佳条件下青稞淀粉的提取率为60.2%.The aqueous enzymatic method was used to extract starch from highland barley by using cellulose as hydrolytic enzyme.Based on the single-factor and orthogonal experiments,the optimal extraction conditions were as follows： cellulose amount 20 EGU/g,hydrolysis time 8 h,temperature 45 ℃ and pH 6.5.Under optimal conditions,the extraction rate the highland barley starch were 60.2%.
