摘要
采用酒石酸水溶液的萃取体系,以果胶收率为主要评价指标,利用正交设计L16(45),优选得到从柚皮中提取果胶的最佳工艺条件:萃取用酒石酸水溶液与柚皮质量比15:1、萃取溶液的pH值1.5、萃取温度90℃、萃取时间60min。按此优选最佳工艺试验柚皮果胶平均收率达到18.73%。
Tartaric acid aqueous extraction system was used,pectin yield as the main evaluation indicators,and the best technical conditions were obtained through orthogonal design L1（645）.The weight ratio of tartaric acid aqueous solution and pomelo peel was 15：1,extraction solution of tartaric acid was controlled at pH 1.5,extraction temperature was 90 ℃,and extraction time was 60 min.Under the best conditions,the average yield of pectin was up to 18.73 %.
