abstract:
The main goal of this study was to evaluate 87Sr/86Sr ratio in different matrices, namely soils, branches,
and grape juices, of an oenological food chain in order to develop a robust analytical strategy able to link
the investigated food to its territory of origin. The 87Sr/86Sr has been used as traceability marker and several
aspects, affected its variability, i.e. geological features of the investigated area, the bio-available fraction
of elements in the soils and the up-take of the plant, have been taken into account. Optimisation of
an analytical procedure for the separation of Sr from its interferences and investigation of the analytical
performances in terms of precision of used methodology have been carried out as well. This work highlighted
a good match between the isotopic values monitored in the bio-available fraction of soils and
their respective grape juices for almost all the investigated areas. The correlation with food satisfyingly
improves when isotopic relative abundance values of branches vine are considered.
