| 摘 要： | 本文采用酸提取乙醇沉淀法从柚皮中提取果胶,分别对水科比、pH值、提取温度、提取时间、乙醇浓度等因素进行了单因素试验,研究这几个因素对果胶提取效果的影响,通过对结果的分析确定酸提取果胶的最佳工艺条件为水料比20∶1,酸度控制在pH值2.0,温度控制在80℃,提取果胶时间为75min,用粉末状的活性炭进行脱色,乙醇浓度为95％.实验结果表明:设计的优化工艺条件生产果胶是可行的,果胶质量是符合要求的,其产率也是理想的.

| Abstract: | This article uses the acid extraction ethyl alcohol precipitation method to withdraw the pectin from the pumelo peel,Distinction adding water material ratio、pH value、Extraction temperature、Extraction time、Factors and so on ethyl alcohol density have carried on the single factor experiment,Studies these factors to the pectin extraction effect influence,Through to result analysis determination acid extraction pectin best technological conditions for Shui Liaobi 20∶1,Acidity control in the pH value 2.0,Temperature control in 80 ℃,The extraction pectin time is 75min,Carries on the decolorization with the powdery activated charcoal,The ethyl alcohol density is 95%.The experimental result indicated: The design optimization technological conditions production pectin is feasible,The pectin quality meets the requirement,Its production rate is also ideal. |
