| 摘 要： | 以干柑桔皮为原料,用混合酸（磷酸-亚硫酸）水解、乙醇沉淀法提取果胶的工艺,考察桔皮中提取果胶的温度、料液比、酸度、提取时间等条件对产率的影响,确定其最适宜条件是：提取时间75 min,料液比为1∶10,温度80℃,酸度pH=4,得率为3.81%.与单一盐酸提取比较,混合酸提取效果较好.

| Abstract: | The process of extracting pectin from the dried orange peel is studied, which is hydrolyzed with mixed acid （ phosphoric acid-sulphurous acid） and precipitated with ethanolIt discusses the influence of tem-perature,the ratio of the orange peel and the mixed acid,acidity and time of extraction on yield of pectin ex-tracted from orange peelThe optimum conditions are as followed：the extraction time 75 min,ratio of mixed acid 1 ∶ 10,temperature 80 ℃ and pH 4. The yield is 3. 81%. Compared with the single hydrochloric acid,the mixed acid has a better extractive effect. |
