摘要
研究了用超临界ＣＯ２流体纯化溶剂法提取辣椒色素的方法．用超临界ＣＯ２流体作萃取剂，从液体或固体物料中实现萃取、分离和纯化物料从而制备高纯度辣椒色素是可行的．使产品符合ＦＡＯ／ＷＨＯ残留溶剂标准要求（已烷含量２５ｍｇ／ｋｇ）的最佳工艺参数是：萃取压力１８ＭＰａ，萃取温度２５℃，萃取剂流量２．０Ｌ／ｍｉｎ，萃取时间３ｈ．
The purification of red chilli colour with supercritical carbon dioxide fluid is studied.Make the use of CO 2 fluid as extractant,from crude meterial to extract,separate and cleanse metrial in order to get the red chilli colour is technically feasible.Extraction pressure is the most important condition to purification.To product in keeping with FAO/WHO the remains solvent standand(the n Hexane content≤25 mg/kg),the best technological conditions are extraction pressure 18 MPa,extraction temperature 25℃,rate of flow carbon dioxide 2.0 L/min and extraction time 3 h.
