Description:
This paper aims to define the stability over the time of chemical elemental patterns in some citrus varieties
of PGI (Protected Geographical Indication) and not PGI Interdonato and Lunario cultivars coming from
Italy and Turkey and to set up a range of markers useful to trace their geographical origin. During the
2015–2017 growing seasons, all fruits were collected and subjected to Inductively Coupled Mass spectrom etry (ICP-MS) analysis, in order to determine the multielemental chemical profiles. The chemical variabil ity was calculated for each element by Multi-way analysis of variance. The results highlighted how the
measured Cr, Ni, Al, K, Fe and Zn levels mainly depend on the soil composition and the fingerprint
allow to trace the geographical origins. Moreover, the stepwise linear discriminant analysis (SLDA) has
allowed to correctly classify the 100% of lemon pulps provenances, based on Ni, Al, K, Ca and Na con tents. Finally, our study demonstrates the role played by harvest years, variety and soils composition
whose interaction contributed to define the chemical fingerprints.
