| Abstract: | The dietary fibre was extracted with acid hydrolysis from burdock dregs. The result of orthogonal experiment indicated that the optimum conditions for extracting soluble fiber were 80℃, pH 2.0, taking time 90?min, water volume 1∶10, And that were 60℃, pH 2.0, 60?min, 1∶5 for insoluble fibre. The extraction rates of soluble and insoluble fibre were 1.0 % and 8.5 % (on the dry basis) respectively. The products smell well and the colors were slightly yellow or light. For insoluble fibre, its expansive capacity was 6.5?mL/g and water holding capacity was 720%. |
