摘　　要：对碱液浸提法提取桔皮膳食纤维的工艺进行了研究。结果表明,提取膳食纤维的最佳工艺条件是:NaOH浓度0.25 mol/L、碱提温度50℃、料液比1∶15、碱提时间30 min。桔皮膳食纤维脱色工艺的最优参数为:双氧水浓度4%、脱色温度30℃、脱色时间5 min、pH值为6。The technology of extracting dietary fiber from orange peel by alkali solution is studied. The results show that the optimum condition of the dietary fiber extraction is 0.25 mol/L of the sodium hydroxide concentration, 50 ℃ of the extraction temperature, 1 ： 15 of the ratio of material and liquid and extracting for 30 minutes. The optimum condition of the decoloration of dietary fiber is 4% of H2O2 concentration, 30 ℃ of the decoloration temperature, pH 7 and decolorizing for 5 minutes.
