Abstract:: The research used dried orange peel as raw material to extract pectin of orange peel by hydrochloric acid extraction and ethanol precipitation method.Effects of ratio of raw material to liquid,pH value,extracting temperature,extracting time and alcohol concentration were investigated through single factor and orthogonal test.The results showed that the ratio of raw material to liquid was the main factors on extraction rate of pectin from orange peel.The optimum extraction process of pectin was as follows: the temperatures was 85℃,the ratio of raw material to liquid was 1∶8,pH 2.0,the extracting time was 45 minutes, the alcohol concentration was 90%.The extracting rate of pectin was up to 14.8%.
