The process for extraction of the insoluble dietary fiber from bamboo shells was studied. The optimal condition of the extraction was gained by orthogonal experiment. The optimal conditions were that NaOH concentration was 1. 0 mol/L, extracting temperature was 30 ℃ and the temperature of H2 SO4 was 50 ℃, the purity was 92. 06%, expansion capacity and water hold capacity was 6. 107 g/g, 8. 730 g/g, respectively. The data showed that significant absorbed capacity of IDF on NO-2 was under pH 2 and pH 7. The data showed that IDF absorbed NO-2 increased while the time increased, and pH 2 was better than pH 7. The capacity that IDF absorbed unsaturated fatty acids was better than saturated fatty.
