Dataset: Identification and quantification of lipids in wild Atlantic salmon, farmed Atlantic salmon (Salmo salar), and salmon feed by GC-MS

The main objective of this study was to determine and quantitate the fatty acid levels in wild and farmed Atlantic salmon, with a focus on the saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids, n-3 and n-6 fatty acids, as well as the nutritional quality indices; the atherogenicity index, the thrombogenicity index, and the n-6/n-3 ratio. This is evaluated in the context of nutritional differences by consumption of these two products. Additionally, the fatty acid profile of salmon feed was also of interest to compare the similarities between the fatty acid composition of farmed salmon and its feed. Three fish of each kind, as well as the salmon feed, were analysed by the use of a GC-MS (ISQ QD, Thermo Fisher Scientific) in TIC acquisition mode, with the accompanying software Chromeleon v.7.2.8. The raw data is presented as retention times and peak area (counts/min). Additionally, the relative area (percentage of total peak area) are also presented for the lipid fractions. In general, the raw data was processed to show the identified fatty acids and their respective quantities in wild and farmed salmon, and salmon feed. These are presented in separate sheets within the file. The respective lipid fractions for both fish are also given as separate sheets. Additionally, three sheets were prepared as comparisons to offer a better overview over the processed data. A table of contents are given to further help the navigation between the sheets. The processed data can be used to give an estimate of the fatty acid levels in wild and farmed Atlantic salmon, as well as salmon feed.

本研究的核心目标为定量测定野生与养殖大西洋鲑（Atlantic salmon）体内的脂肪酸水平，重点覆盖饱和脂肪酸、单不饱和脂肪酸、多不饱和脂肪酸、n-3及n-6脂肪酸，同时纳入多项营养质量评价指标：致动脉粥样硬化指数、致血栓形成指数以及n-6/n-3比值。研究围绕两种大西洋鲑产品的食用营养差异展开对比评估。此外，本研究亦关注鲑鱼饲料的脂肪酸组成，旨在对比养殖大西洋鲑与其饲料的脂肪酸成分相似性。本研究选取两种大西洋鲑各3尾及鲑鱼饲料样本，采用气相色谱-质谱联用仪（GC-MS，型号ISQ QD，赛默飞世尔科技（Thermo Fisher Scientific））在总离子流（TIC）采集模式下进行分析，配套使用Chromeleon v.7.2.8软件完成数据处理。原始数据以保留时间与峰面积（计数/分钟，counts/min）的形式呈现。此外，脂质组分的相对峰面积（占总峰面积的百分比）亦同步提供。总体而言，原始数据经处理后，可展示已鉴定的脂肪酸及其在野生大西洋鲑、养殖大西洋鲑与鲑鱼饲料中的对应含量，相关结果以数据集文件内的独立工作表形式分别呈现。两种大西洋鲑的对应脂质组分数据亦以独立工作表形式提供。此外，数据集还设置了3个专用工作表用于数据对比，以更清晰地概览处理后的数据。数据集附带目录表，以进一步辅助用户在各工作表间进行导航。本数据集的处理后数据可用于估算野生大西洋鲑、养殖大西洋鲑以及鲑鱼饲料中的脂肪酸水平。
