OBJECTIVESMain Objective: Demonstrate the usefulness of combinedtechniques (TE + isotopic fingerprint) to predict the origin of dried milk and theinfluence of diverse feeding and environmental conditions on this fingerprint. Specific Objectives:a) To verify SOPs for measuring TE and stable isotopes (lightand heavy) in agricultural soil, forage, water and milk (dried). Evaluation ofLODs LOQs, accuracy, QA-QC parameters, etc.b) To measure TE and stable isotopes  in CRMs and also in samples (soil, water,forage and dried milk)collected from diverse regions belonging to the main milkproducing area of Argentina (Provinces of Santa Fe and Córdoba). Thus,analyzing authentic samples with dried milk produced in the laboratory.c) To evaluate elements-isotopes within the TE+ isotopic fingerprint,allowing to differentiate milk from diverse regions using chemometrics toevidence which parameters are the most important to point out such differences.d) To verify the matching between soil-water-forage and milkcomposition using appropriate multivariate correlations (canonical correlationanalysis (CCA), Generalized Procrustes Analysis (GPA), etc.).e) To compare our results withresults from other latitudes looking for a generalized model that could beexpanded to other countries, continents, verifying the scope of developedmethods to predict the origin and, if possible, the safety of dairy products.
