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测定并定量分析野生与养殖大西洋鲑鱼体内的脂肪酸水平，重点关注饱和脂肪酸、单不饱和脂肪酸、多不饱和脂肪酸、n-3与n-6脂肪酸，同时涵盖三类营养质量指数：致动脉粥样硬化指数（atherogenicity index）、致血栓形成指数（thrombogenicity index）以及n-6/n-3比值。本研究结合两种鲑鱼产品的食用营养差异展开评估。此外，本研究亦关注鲑鱼饲料的脂肪酸组成，以对比养殖鲑鱼与其饲料的脂肪酸成分相似性。 本次研究采用气相色谱-质谱联用仪（GC-MS，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。研究共对每组3尾样本及鲑鱼饲料开展检测，原始数据以保留时间与峰面积（计数/分钟，counts/min）形式呈现；此外，还提供了脂质组分的相对面积（占总峰面积的百分比）数据。 总体而言，原始数据经处理后可展示野生与养殖大西洋鲑鱼及鲑鱼饲料中已鉴定脂肪酸及其对应含量，相关结果以文件内独立工作表形式呈现。两种鲑鱼对应的脂质组分数据亦单独列为工作表。此外，还设置了三张工作表用于数据对比，以更直观地概览处理后的数据。文件附带目录表，以进一步协助用户在各工作表间导航。本研究处理后的数据可用于估算野生与养殖大西洋鲑鱼及鲑鱼饲料中的脂肪酸水平。
