Title: Research on Conditions of Extracting Pectin from Orange Skin
Abstract: Orange peel was used as raw material,the method of acid hydrolysis was taken to extract the pectin from orange peel,gravimetric method was applied to measure the content of pectin in the extraction solution,the effects of different extracting factors on the extracting rate of pectin and the optimum extracting conditions were researched through orthogonal experiment.The optimum extracting conditions were concluded as follows: ratio of water to orange peel 20∶1,extraction temperature 70℃,pH-value 1.5,extraction time 90 min.Under the above optimum conditions,the extracting rate of pectin could reach to 20.43%.
