This invention relates to a method for separating EPA and DHA from fish oil, belonging to the field of separation technology. First, utilizing the difference in esterification rates of EPA and DHA by lipase RM, a selective esterification reaction of fish oil fatty acids with lauryl alcohol is catalyzed, thereby constructing a polar binary system of low-polarity EPA-lauryl ester and high-polarity DHA fatty acid. Then, a PDA-mSiO2 / PDMS composite membrane, prepared from polydimethylsiloxane, mesoporous silica, and polydopamine in a specific mass ratio, is used as the filter medium. The system is filtered using a dual-action mechanism of "size sieving-hydrogen bond affinity," achieving efficient permeation of EPA-lauryl ester and selective retention of DHA fatty acid. Finally, the crude EPA-lauryl ester solution on the permeation side and the concentrated DHA fatty acid solution on the retention side are purified by low-temperature distillation, achieving efficient and green separation of EPA-lauryl ester and DHA fatty acid.
