The present invention relates to the field of methods for purifying fatty acid ethyl esters. According to the present invention, a method for obtaining a ?3 fatty acid ethyl ester, such as EPA and DHA, each as a high purity product at a high yield is provided. In the method according to the present invention, a raw material fat including EPA and DHA is treated with a lipolytic enzyme and ethyl-esterification is performed as needed; the treated substance is fractionated into a glyceride fraction and a free fatty acid fraction; a fraction comprising more EPA ester and a fraction comprising DHA ester are obtained from the respective fractions; the fraction comprising more EPA ester is purified to prepare a high-purity EPA ester; and the fraction comprising more DHA ester is purified to prepare a high-purity DHA ester.

A method for squalene extraction from a seed oil includes converting fatty acids of the seed oil into soap by subjecting the seed oil to a saponification reaction to obtain a saponified product, and adsorbing the fatty acids of the seed oil on surfaces of iron oxide nanoparticles to obtain iron oxide nanoparticles coated with fatty acids. The method may further include washing the iron oxide nanoparticles coated with fatty acids with a polar solvent to obtain a third mixture including a polar phase and the iron oxide nanoparticles coated with fatty acids, separating the iron oxide nanoparticles coated with fatty acids from the third mixture by a magnetic field, mixing the polar phase with a non-polar solvent and distilled water to obtain a two-phase solution, the two-phase solution including a non-polar phase and an aqueous phase, and separating and drying the non-polar phase to obtain squalene.
