【摘要】 本文着重研究了以传统溶剂萃取法得到的辣椒油树脂为原料，以无毒、易得、价廉的ＣＯ２为萃取剂，采用超临界萃取的方法提取辣椒红色素。通过对萃取压力、萃取温度、萃取时间、ＣＯ_２流量等条件的试验，获得了最佳的工艺参数。试验结果表明，超临界萃取法具有工艺简单、操作安全、产品质量好、萃取效率高等优点。更多还原

【Abstract】 In this study the red chilli colour has been extracted by supercritical carbon dioxide from capsicum oleoresin.The optimum technological parameters were determined by changing the pressure,temperature and the flow of CO2. The results show that the extracting technology with high extraction yield and better products is very simple and safe.更多还原
