mEAT quality Dataset - Isotope ratios and mineral elements

This dataset was generated within the study associated with the article “Multi-Country Study of Stable Isotopes and Mineral Elements in European Pork” published in MDPI Foods. It includes analytical data from 612 pork samples (Longissimus thoracis et lumborum) collected from 12 farms located in four European countries: Denmark, Poland, Italy and Spain. The farms adopted different production and rearing systems. The dataset contains measurements of five stable isotope ratios (δ13C, δ15N, δ34S, δ18O, and δ2H) together with concentrations of 27 mineral elements. Mineral element data are reported both on a dry matter basis and on a wet-weight basis. Additional metadata related to farming systems are included, such as farm geographic coordinates, breed type, feeding regime (C3 or mixed C3+C4 plants) and slaughter month. The dataset was developed to support studies on geographical origin authentication, traceability, and characterization of European pork production systems.本数据集源自发表于MDPI旗下期刊《Foods》的论文《欧洲猪肉中稳定同位素与矿物元素多国研究》（Multi-Country Study of Stable Isotopes and Mineral Elements in European Pork）的关联研究。数据集涵盖了采自丹麦、波兰、意大利、西班牙4个欧洲国家12家养殖场的612份猪肉样本（背最长肌与腰最长肌，Longissimus thoracis et lumborum）的分析数据，上述养殖场采用了差异化的生产与饲养体系。 数据集包含5种稳定同位素比值（δ¹³C、δ¹⁵N、δ³⁴S、δ¹⁸O及δ²H）的检测数据，以及27种矿物元素的浓度信息。矿物元素数据同时以干物质基准和鲜重基准两种形式报告。 数据集还附带与养殖体系相关的补充元数据，包括养殖场地理坐标、畜禽品种类型、饲喂方案（C3植物或C3与C4混合植物）以及屠宰月份。 本数据集旨在为欧洲猪肉的地理来源鉴定、产品可追溯性以及生产体系特征分析相关研究提供支撑。
