摘　　要：提取磷脂常用的方法主要有:有机溶剂提取法和超临界CO2提取法两大类。有机溶剂提取的磷脂中残留有机溶剂量往往超标,使磷脂的使用受到极大的限制,而超临界CO2提取以其绿色化工艺逐渐受到人们的重视。对目前采用超临界CO2萃取技术提取大豆磷脂和蛋黄磷脂的典型工艺进行了分析、归纳和总结,同时提出了当前提取磷脂面临的困难及相应的解决方案。The structure of the phospholipids and their properties were summarized. The representative supercritical carbon dioxide extraction methodology of extracting the phospholipids from the soybean oil or the egg yolk was analyzed. The difficulties and solutions about separating and purifying the phospholipids were put forward.
