1. A process for the extraction of lipids including fatty acids from Perna canaliculus solids comprising mixing said solids with a solvent 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 to leave extracted lipids, wherein the solvent is selected from the group consisting of acetone, hexane and ethyl acetate.
