Traceability of Protected Geographical Indication (PGI) Interdonato lemon pulps by chemometric analysis of the mineral composition
In the last years, element content has been used as geographical tracer to determine the provenance of food. In the present work the content of 19 minerals (K, Ca, Mg, Na, Fe, Zn, B, Cu, Al, Mn, Ni, Cr, Pb, Co, As, Se, Cd, Sb
and V) and 13 lanthanide elements (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm and Lu) in Protect Geographical Indication (PGI) Interdonato lemon Messina (Italy) and non-PGI Turkish lemon pulps was evaluated
