正交试验优选假酸浆籽中果胶提取工艺的研究

Optimization on extracting of seeds of Nicandra Physaloides by Orthogonal Experiment

目的优选假酸浆籽中果胶提取工艺,测定其果胶的含量。方法以果胶提取率为评价指标,采用正交设计法进行实验,用水提醇沉、真空干燥法制备果胶。结果最佳工艺为:料液比1∶15、温度65℃、提取时间60min共2次、醇沉浓度70%;假酸浆籽中含果胶为8.06%。结论该工艺稳定,所得果胶含量高、品质好。

Objective To optimize extracting technology and content Determination of pectic in seeds of Nicandra Physaloides.Method Extraction efficiency as evaluation indexes,the pectic was preparation by water extraction and vacuum drying with Orthogonal Experiment.Results The optimum technology were Ratio of liquid to material 1：15,temperature 65 ℃,extraction for 60 min,ethanol concentration 70%,pectic content were 8.06%.Conclusion This technics were stable,pectic content were many and quality were good.
