O1: Following the isotope fingerprint on the entire production chain: soil, water, fodder, and egg samples, by IRMS, as tool for geographical origin discrimination
O2: Assessing elemental signature (macro- and microelements, rare earth elements, metals with toxic potential) of soil, water, fodder, and egg samples, by ICP-MS, as an instrument for eggs discrimination
O3: Assessing the potential of the δ18O and δ2H values changes as traceability markers for eggs storage
O4: Eggs quality assessment through the fatty acids determination from egg yolk by GC-FID
O5: Chemometric model development and validation of obtained data, in order to obtain the best markers to differentiate eggs geographical origin, their specific characteristics, and to differentiate the egg samples according to hens ‘age. Chemometric model testing by using unknown egg samples
O6: Promoting the project results through their dissemination, extending the analytical services offer of CO (INCDTIM)
