“…According to this EU resolution, traceability is an instrument for tracing and tracking any food commodity, through all phases of the supply chain from collection/production to the market (European Commission, 2002). Different types of tags have been developed from elemental and isotopic (Bennion et al., 2021; Davis et al., 2021; Duarte, Duarte, et al., 2022; Mamede et al., 2022), biochemical (Fonseca et al., 2021; Portarena et al., 2015; Ricardo et al., 2015), genomic (e.g., Galimberti et al., 2014; Ogden, 2008), and spectral analyses (e.g., Duarte, Mamede, Carreiras, et al., 2022; Ghidini et al., 2019; Ren et al., 2013; Varrà, Ghidini, et al., 2021). Additionally, different methodologies have been implemented for the development of these tags, from simple statistical multivariate analysis (Duarte, Duarte, et al., 2022; Varrà et al., 2019) to advanced multi‐model chemometrics approaches (Duarte, Mamede, Duarte, et al., 2022; Varrà, Ghidini, et al., 2021) and machine learning algorithms (Milan et al., 2019).…”
