| 摘 要： | 高纯度辣椒碱在医药、食品等领域有着很大的市场需求。以干辣椒为提取原料,采用多元价值取向模型对现有溶剂法、超临界萃取、溶剂-超临界耦合及溶剂-离子交换耦合4种提取高纯辣椒碱工艺进行了综合评价,评估结果表明溶剂法耦合离子交换法工艺明显优于其他工艺路线,其综合优度为0.8049。在此基础上对最佳的溶剂-离子交换耦合工艺开展了实验研究,得出最优提取工艺参数为:上柱浓度331.4 mg·L-1,速度18.8 ml·min-1,pH值5.0,温度为室温,并且得出上柱纯化溶液浓度、流速等相关参数值及作用。制得的产品辣椒碱纯度高达98.42%。

| Abstract: | High purity capsaicin is in great demand in the fields of medicine and food.The multi-element valued model is used to evaluate four capsaicin extraction technologies including solvent extraction,supercritical fluid extraction,coupled solvent-supercritical extraction and coupled solvent-ion exchange route.The results confirm that coupled solvent-ion exchange route is the optimal technological process,preceding other routes obviously.Experimental study on the coupled solvent-ion exchange route shows that the optimum parameters for capsaicin extraction are:initial concentration 331.4 mg·L-1,flow rate 18.8 ml·min-1,pH 5.0,and room temperature.The column purification parameters such as the solution concentration and velocity with its effects are also obtained,and the capsaicin purity of final production reaches 98.42%. |
