Study on technology research of wild Zingiber striolatum in Fanjing mountain’s water soluble dietary fiber

Wild Zingiber strioatums in Fanjing Mountain were materials and ultrasonic method was used,based on 4 fundamental single factors,these were power extraction,temperature and time and ratio of material to liquid,by means of L9(34) orthogonal test,process conditions were optimized about water-soluble dietary fiber of Wild Zingiber strioatums. The results showed that the optimal technique conditions were extraction time was 39min,ultrasonic power was 120W,extraction temperature was 63℃ ,solid -liquid ratio was 1∶41g/mL. Under these optimum conditions,the SDF extraction rate was 3.33%.
