Abstract：T his experiment takes A rctium lap p a as raw material to study the effects of cellulase en-zyme dosage,ultrasonic power and wave of the content of its water-soluble dietary fiber.The response sur-face methodology is used to optimize the process conditions and to explore its functionality.The experimen-tal results showed that the optimal conditions for preparing the water-soluble dietary fiber are as follows:2.0% cellulase,25 min ultrasonic time,150 W ultrasonic power.The eXtraction rate of water-soluble dieta-ry fiber is 36.54% under this condition and showes strong scavenging activity for both · O2-and DPPH which is increased with concentration,but the scavenging capacity is lower than that of vitamin C.The wa-ter holding capacity is 405.7%,eXpansion force 7.04 mL/g,oil holding capacity 209.9%.
