Abstract
A method for separating polar lipids from plant material, in particular, intact algal cells, using an amphipathic solvent set and a hydrophobic solvent set. Some embodiments include dewatering intact algal cells and then extracting polar lipids from the algal cells. The methods provide for single and multistep extraction processes which allow for efficient separation of algal polar lipids from a wet algal biomass while avoiding emulsification of extraction mixtures. These polar lipids are high value products which can be used as surfactants, detergents, and food additives. Neutral lipids remaining in the algal biomass after extraction of polar lipids can be used to generate renewable fuels.
