    • Fatty acid esters such as those containing arachidonic acid (AA) and docosahexaenoic acid (DHA) derived from lipid mixtures are prepared with reduced levels of sterols and phosphorus. A preferred embodiment of the invention comprises extracting lipids from egg with methanol; separating lipids including sterols from insoluble egg components; submitting the methanolic solution of lipids to transesterification and subsequent neutralization to convert the lipids to methyl esters of said free fatty acids together with sterols; separating the said sterols and esters from an aqueous phase including phosphorus compounds formed in the transesterification; subjecting the said fatty acid esters and sterols to distillation to separate sterols from the fatty acid esters; and subjecting the said esters to transesterification in the presence of glycerol to produce triglycerides of said esters thereof including that of AA and DHA wherein the resulting triglycerides contain reduced quantities of sterols and phosphorus.
    • 脂肪酸酯如含有花生四烯酸(AA)和来源于脂质混合物的二十二碳六烯酸(DHA)的脂肪酸酯被制备成具有降低水平的固醇和磷。 本发明的优选实施方案包括用甲醇从鸡蛋中提取脂质; 分离包括固醇的脂质不溶于蛋组分; 将脂质的甲醇溶液酯交换并随后中和,将脂质与甾醇一起转化成所述游离脂肪酸的甲酯; 将所述甾醇和酯与包含在酯交换中形成的磷化合物的水相分离; 对所述脂肪酸酯和甾醇进行蒸馏以将甾醇与脂肪酸酯分离; 并在所述甘油存在下使所述酯进行酯交换反应以产生所述酯的甘油三酸酯,其包括AA和DHA的甘油三酯,其中所得甘油三酸酯含有减少量的甾醇和磷。
