摘要
研究了用超临界ＣＯ２萃取技术与硝酸银络合相结合的方法，从鱼油提取分离高纯度二十二碳六烯酸（ＤＨＡ）的试验工艺。结果表明：单独用超临界ＣＯ２只能将ＤＨＡ浓缩到７５％左右；而用两步法则可获得纯度为９５％以上的ＤＨＡ。
xtraction of high purified docosahexaenoic acid(DHA) from fish oils was studied.The results showed that the purity of DHA was concentrated to 75%with supercritical CO_2(SC—CO_2) extraction technology alone,but it was raised to 95% by the combination of SC—CO_2 extraction and AgNO_3-complex.
