| Abstract: | 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. |
