Chemical and liquid chromatography-mass spectrometry (LC/MS)-based lipidomics analyses were performed to explore the alterations in lipid profiles in the hairtail muscle during air-drying. The peroxide value (POV) and carbonyl group value (CGV) in the air-dried hairtail (ADH) significantly increased with air-drying time. Lipidomics results revealed 1,326 lipids, which were grouped into 33 lipid categories, including 422 triglycerides (TGs), 170 phosphatidylcholines (PCs), 110 phosphatidylethanolamines (PEs), among others. In addition, ADH contained 131 and 201 differentially abundant lipids (DALs) at high and low levels, respectively. Among them, DALs, TGs, PCs, LPCs, and LPEs could be used to distinguish between ADH and FH samples. The apparent alterations in ADH and FH samples were attributed to lipid decomposition, side-chain modifications during oxidation, or oxygen- and salt-promoted lipid oxidation. Thus, this study provides a more comprehensive understanding of hairtail lipid profiles before and after air-drying which can be used as a guide for hairtail products.
采用化学和基于液相色谱 - 质谱联用（LC/MS）的脂质组学分析方法，以探究带鱼肌肉在风干过程中脂质谱的变化。风干带鱼（ADH）中的过氧化值（POV）和羰基值（CGV）随风干时间显著增加。脂质组学结果显示了1326种脂质，它们被分为33类脂质，包括422种甘油三酯（TGs）、170种磷脂酰胆碱（PCs）、110种磷脂酰乙醇胺（PEs）等。此外，ADH分别含有131种和201种高水平和低水平的差异丰富脂质（DALs）。其中，DALs、TGs、PCs、溶血磷脂酰胆碱（LPCs）和溶血磷脂酰乙醇胺（LPEs）可用于区分ADH和新鲜带鱼（FH）样本。ADH和FH样本中明显的变化归因于脂质分解、氧化过程中的侧链修饰或氧和盐促进的脂质氧化。因此，本研究提供了对带鱼风干前后脂质谱更全面的理解，可为带鱼产品提供指导。
