| Abstract: | Extraction of pectin from orange peels by microwave radiation with mixed acid as extracting reagent was investigated. The influence factors such as proportion of reagent, microwave radiant power, radiant time, pH of the extraction and the last consistency of ethanol were studied in single factor test. The results showed that the optimum conditions were as follows ： the power of the microwave of 560 W ; the calefaction time of 5 min; the volume of water to the weight of orange peel of 15：1 ; pH value of extraction of 2.0 ,the concentration of ethanol 60%. The output ratio of pectin of 20.88% was obtained on the optimum conditions. |
