Abstract:
1. A process for recovering a lipid composition comprising predominantly neutral lipid from a biomass, wherein the biomass comprises cellular debris, at least one long chain polyunsaturated fatty acid (LCPUFA) and at least one other compound, the process comprising the steps: (a) contacting the biomass with a nonpolar solvent to recover lipid in an extraction process; (b) processing the lipid composition by at least one step selected from the group consisting of refining the lipid composition, bleaching the lipid composition, and deodorizing the lipid composition and combinations thereof; (c) adding a polar solvent to the lipid composition; (d) cooling the polar solvent and lipid composition to selectively precipitate at least one other compound; and (e) separating the precipitated other compound from the lipid composition.
