Selective extraction of phospholipids from food by-products by supercritical carbon dioxide and ethanol and formulating ability of extracts

Selective extraction of phospholipids (PLs) from camelina press cake and scallop by-products was investigated using Supercritical Fluid Extraction at 45 °C, 25 MPa, with (2–30%) ethanol (EtOH) as co-solvent. A two-step process consisting of a first extraction with CO2 + 7% EtOH to eliminate neutral lipids followed by a second extraction with CO2 + 30% EtOH led to extracts containing up to 40% of the PLs initially present in the matrix.
