摘要
采用酒石酸水溶液的萃取体系,利用正交设计,优选得到从柑桔皮中提取果胶的最佳工艺条件:萃取用酒石酸水溶液与桔皮物料比25:1、萃取溶液的pH值1.5、萃取温度90℃、萃取时间90min。按此优选最佳工艺试验,桔皮果胶平均收率达到17.08%。
Pectin was extracted from orange peel using tartaric acid aqueous as extraction system. The best technical conditions were obtained through orthogonal experiment, as follows： weight ratio of tartaric acid aqueous solution and orange peel was 25 ： 1, pH of extraction solution was 1.5, extraction temperature was 90 ℃, and extraction time was 90 min. Under the best conditions, the average yield rate of pectin was up to 17.08 %.
