| 摘 要： | 以干燥的柑橘皮为试材,采用酸解醇沉法提取果胶,通过单因素实验及正交实验研究料液比、pH值、浸提温度、浸提时间以及乙醇浓度对柑橘皮果胶提取率的影响。结果表明:料液比是影响柑橘皮果胶提取率的最主要因素;提取果胶的最优工艺条件为:浸提温度85℃、料液比1∶8、pH 2.0、浸提时间45min、乙醇浓度为90%,在此条件下,柑橘皮果胶的提取率达到14.86%。

| Abstract: | The research used dried orange peel as raw material to extract pectin of orange peel by hydrochloric acid extraction and ethanol precipitation method.Effects of ratio of raw material to liquid,pH value,extracting temperature,extracting time and alcohol concentration were investigated through single factor and orthogonal test.The results showed that the ratio of raw material to liquid was the main factors on extraction rate of pectin from orange peel.The optimum extraction process of pectin was as follows: the temperatures was 85℃,the ratio of raw material to liquid was 1∶8,pH 2.0,the extracting time was 45 minutes,the alcohol concentration was 90%.The extracting rate of pectin was up to 14.8%. |
