This study was extract phospholipids (PL) from squid-viscera which is uselessness on food industry. PL were successfully extracted from squid-viscera by using supercritical carbon dioxide (SC-CO2). The freeze dried squid-viscera powder was extracted with SC-CO2 at 200
bar and 45°C for removing non polar molecule. The power subjected to ethanol and acetone extraction for the enrichment of PL. The extraction yield obtained by SC-CO2 powder (6g of extract per 100g sample) can be compared with the freeze dried powder (4g of extract per 100g sample). HPLC analysis coupled with an evaporative light scattering detector (ELSD) showed selectivity in the SC-CO2 extraction of the PL components. SC-CO2 extraction showed more extraction of Phosphatidic acid (PA) than solvent extraction (PA 6% high, PI 2% high), But SC-CO2 showed less Phosphatidyl ethanolamine (PE) and Phosphatidyl choline (PC) (PE 6% low, PC 11% low).
