Study on modification of dietary fiber from wheat bran

摘要：

The modification of the pretreated wheat bran by extrusion technology and cellulose enzyme method was studied to improve the content of soluble dietary fiber and enhance product functionality. First ,the pretreated dietary fiber (DF1) was modified by extrusion technology to get DF2,then DF2 were modified by enzymolysis of cellulose enzyme. The results showed as fowllow: the optimum conditions for extrusion modification was 45％ material moisture content, 25 r·min-1 feeding speed, 200 rminscrew speed, 70-90110-130-150℃extrusion temperature, and the SDF content of DF2 is 33.95％. the optimal enzymatic modification conditions for DF2 was 1 :0solid-liquid ratio, 30U/g enzyme adding, 4h enzymatic hydrolysis time.
