In this paper, ultrasonic water and ultrasonic-enzymatic extracting methods were used to extract water-soluble dietary fiber of peanut meal, which was used as material. The effects of solid/liquid ratio, ultrasonic time, ultrasonic power and enzyme quantity on extracted rate were discussed. Orthogonal test was used to optimized extracting conditions and research its functionality. The results showed that the optimal extracting conditions were as follows. Solid/liquid ratio was 1∶30 g/mL, ultrasonic time was 25 min, ultrasonic power was 150 W, the highest extracted rate of water-soluble dietary fiber of peanut meal was 12.56 %. The optimal extracting conditions of ultrasonic-enzymatic method were solid/liquid ratio 1∶25 g/mL, ultrasonic 15 min, 2%enzyme, 175 W. Extracted rate of water-soluble dietary fiber of ginger was 15.84 %, higher than ultrasonic water extracting method, 26.11%. Water-soluble dietary fiber of peanut meal was characterized by higher ability to scavenge·O2-. IC50 of both was 0.33 mg/mL respectively. Retention ability of soluble dietary fiber of peanut meal was 404 %, expansibility was 2.70 mL/g.
