Abstract
The present study focused on the concentration and purification of omega-3 fatty acids from Pharaoh cuttlefish (Sepia pharaonis) caught in the regions of Gwatar, Chabahar, Hormuz Island, Bandar Abbas, Bushehr, and Hendijan located in southern Iran using the urea complexation method at crystallization temperatures of +5°C, +1°C, and -5°C. The results of concentrating and purifying omega-3 fatty acids from the oil extracted from samples collected at different stations at +5°C showed that the concentrated oil from the Chabahar sample had the highest PUFA content (49.1%) with a significant difference, while the concentrated sample from Bushehr contained the highest MUFA (12.6%) and SFA (18.35%) content (P
