摘要： Twelve categories of polar lipids (PLs) were quantified in round scad and hairtail during salt-drying with electrospray ionization-tandem mass spectrometry based on lipidomics. The major species were phosphatidylcholine (PC), phosphatidylethanolamine (PE), and ether-linked PC (ePC), accounting for 67.8%, 11.1%, and 9.7% of total PLs in the raw round scad respectively, and 74.3%, 7.3%, and 10.9% in raw hairtail. Among the 272 and 263 kinds of PLs molecules detected in the two raw fish respectively, only 125 and 94 PLs were strongly affected by salt-drying, including 28 PCs, 23 PEs, 21 ePCs, 9 phosphatidylinositols (PIs), 14 phosphatidylserines/phosphatidic acids/phosphatidylglycerols (PSs/PAs/PGs), 12 lysophosphatidylcholines (LPCs), 5 lysophosphatidylethanolamines (LPEs), 9 ether-linked PEs (ePEs), 4 sphingomyelins (SMs) in round scad, and 21 PCs, 17 PEs, 15 ePCs, 10 PIs, 7 PSs/PAs/PGs, 9 LPCs, 5 LPEs, 6 ePEs, 4 SMs in hairtail. Salt-drying had a very different effect on the two fish. Ultimately, the total PLs content decreased slightly (p > .01) in salt-dried round scad product while increased significantly in hairtail final product (p < .01). Practical applications The change of PLs caused by salt-drying is closely related to the flavor and quality of fish products, and is very important for fish preservation and processing.
