桔皮中提取果胶的工艺

Extraction Technology of Pectin from Orange Peel

对桔皮果胶的提取工艺进行了研究。实验研究了酸提取果胶的过程中提取液pH值、料液比、微波功率、微波时间等反应条件对产率的影响。结果表明,果胶的最佳提取条件为:提取液pH值为1,料液比为1∶20g/mL,微波功率为460W,微波辐射时间为6min,果胶得率21.3%。

Extraction technology of pectin from orange peel was studied.The factors such as pH,ratio of material to liquid,microwave power and time were discuussed.Optimal extracting conditions were confirmed as follows：pH for extraction solution was 1,ratio of material to liquid was 1∶20g/mL,while microwave power was 460W and microwave heating time was 6min.Under the above conditions,the extraction rate of pectin was 21.3%.
