摘　　要：为研究过氧化氢对葛渣膳食纤维的改性作用,以葛根加工淀粉后的残渣为原料,采用单因素与正交试验,以可溶性膳食纤维得率以及不溶性膳食纤维膨胀力为指标,得出了过氧化氢改性制备葛渣膳食纤维的最佳工艺条件,即H_2O_2体积分数0.3%,pH为12,温度为90℃,时间为75 min,得到可溶性膳食纤维得率最高为52.16%,不溶性膳食纤维膨胀力为7.01 m L/g。In order to explore the modification effect of hydrogen peroxide on dietary fiber of pueraria residue. The pueraria residue after starch extraction was selected as raw material, by single factor and orthogonal experiments, and with the yield of soluble dietary fiber（SDF） and the swelling ability of insoluble dietary fiber（IDF） as indicators, the optimal technological conditions for the modification were as follows ： H_2O_2 concentration 0.3%, pH value 12, temperature 90 ℃, time 75 min. Under the optimum conditions, the yield of soluble dietary fiber was 52.16%, and the swelling ability of insoluble dietary fiber was 7.01 m L/g.
