This study aimed at the consecutive extraction of neutral and polar lipids (phospholipids) from skipjack tuna (Katsuwonus pelamis) byproducts using an entrainer (ethanol) combination of green extraction system supercritical carbon dioxide. The head, viscera, and skin of tuna fish were subjected to extraction. The highest proportion of lipids was obtained from the skin (31.18% ± 0.59%), and the net phospholipids were obtained from the head (3.24%). Oils and phospholipids are rich in omega-3 and omega-6 polyunsaturated fatty acids. Phospholipids were identified and their composition was analyzed based on ³¹P NMR spectra. Three important classes of phospholipids are phosphatidylcholines (PC), phosphatidylethanolamine (PE), and lysophosphatidylcholine (LPC). Tocopherol is the major vitamin present in oils and phospholipids from K. pelamis byproducts. Thermogravimetric analysis and differential thermogravimetric analysis confirmed that the extracted neutral and polar lipids are stable at cooking temperatures and can be used in various industries.

本研究旨在使用绿色萃取系统超临界二氧化碳的夹带剂（乙醇）组合从鲣鱼（ Katsuwonus pelamis ）副产品中连续提取中性和极性脂质（磷脂） 。金枪鱼的头、内脏和鱼皮均被提取。从皮肤中获得的脂质比例最高（31.18%±0.59%），从头部获得的净磷脂（3.24%）。油和磷脂富含 omega-3 和 omega-6 多不饱和脂肪酸。根据³¹ P NMR 谱鉴定了磷脂并分析了其组成。磷脂酰胆碱(PC)、磷脂酰乙醇胺 (PE) 和溶血磷脂酰胆碱 (LPC)是三类重要的磷脂。生育酚是来自K. pelamis副产品的油和磷脂中的主要维生素。热重分析和差热重分析证实，提取的中性和极性脂质在蒸煮温度下稳定，可用于各个行业。
