摘要
以柑橘皮为原料,用酸水解法提取其中的果胶,通过重量法测定提取液中果胶的含量,研究不同因素对果胶提取率的影响,结合正交试验确定最佳提取工艺条件。主要结论:从柑橘皮中提取果胶的最佳工艺条件为料液比1∶20、温度70℃、pH1.5、时间90 min,果胶提取率可达20.43%。
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 extrac- ting 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%.
