Metabolomics approaches, such as direct anal. in real time-high resolution mass spectrometry (DART-HRMS), allow characterizing many polar and non-polar compounds useful as authentication biomarkers of dairy chains. By using both a partial least squares discriminant anal. (PLS-DA) and a linear discriminant anal. (LDA), this study aimed to assess the capability of DART-HRMS, coupled with a low-level data fusion, discriminate among milk samples from lowland (silages vs. hay) and Alpine (grazing; APS) systems and identify the most informative biomarkers associated with the main dietary forage. As confirmed also by the LDA performed against the test set, DART-HRMS anal. provided an accurate discrimination of Alpine samples; meanwhile, there was a limited capacity to correctly recognize silage- vs. hay-milks. Supervised multivariate statistics followed by metabolomics hierarchical cluster anal. allowed extrapolating the most significant metabolites. Lowland milk was characterised by a pool of energetic compounds, ketoacid derivates, amines and organic acids. Seven informative DART-HRMS mol. features, mainly monoacylglycerols, could strongly explain the metabolomic variation of Alpine grazing milk and contributed to its classification. The misclassification between the two lowland groups confirmed that the intensive dairy systems would be characterised by a small variation in milk composition
