Solvent extraction of lipids such as essential fatty acids

摘要

Lipids (including fatty acids) are extracted from animal solids such as powdered, freeze dried or fresh meat of green lipped mussel (Perna canaliculus) by mixing said solids with a solvent such as acetone capable of dissolving lipids therefrom to form a solvent extract, removing solvent from said extract by nanofiltration to produce a concentrated lipid extract and recovered solvent, and removing further solvent from the concentrated extract by rotary evaporation to leave extracted lipids particularly rich in eicosatetraenoic acids (ETA's).
