Taking the Ziziphus jujuba var.spinosa as raw material, to extract insoluble dietary fiber ( IDF) .Based on the single factor experiment, orthogonal experiment on influence of A ( NaOH concentration) , B ( the ratio of to liquid) , C ( extraction temperature) and D ( extraction time) on the yield of insoluble dietary fiber from the Ziz-iphus jujuba var.spinosa was processed.The results showed that the impact of these factors on the yield of dietary fiber extracted from Ziziphus jujuba var.spinosa was A>C>B>D;the optimum extraction process of insoluble dietary fiber was:temperature of 50℃, ratio of material to liquid 1︰5 g/mL, 3 %NaOH concentration, 40 min.Un-der the optimized condition, yield of the insoluble dietary fiber could up to 37.9 %, the production was a powder with light yellow color, and its water holding capacity, oil absorption capacity, and expansion rate were 3.586 7 g/g, 2.390 6 g/g and 22.2 mL/g respectively.
