Determining the regional origin of cheeses with trace metal analysis using statistical classifiers [Italy]

Summary: | Some trace elements (Li, K, Mn, Se, Rb, Cs) are dosed in cow and sheep cheeses coming from three different geographical areas in order to identify their place of origin. The samples were obtained from milk collected during Winter and Spring for two production years. It has been pointed out that it was possible to discriminate the place of origin of cheeses clearly, regardless of their type (cow or sheep). Furthermore, if a data set related only to sheep samples is used, it is only necessary to dose the alkali elements (Li, K, Rb), whereas, if a data set regarding the cow cheeses is considered, all six elements analysed are taken into consideration, in order to obtain a significant differentiation between the regions
Per determinare l'origine geografica di formaggi vaccini ed ovini provenienti da tre diverse regioni italiane sono stati dosati alcuni elementi in traccia (Li, K, Mn, Se, Rb, Cs). I campioni sono stati ottenuti da latti raccolti durante l'inverno e la primavera per due anni consecutivi. Il contenuto di elementi in traccia è un efficace strumento in grado di discriminare il luogo di origine di questi formaggi. È interessante notare che per discriminare l'origine dei formaggi ovini sono sufficienti soltanto tre elementi (Li, K, Rb), mentre per discriminare quelli vaccini è necessario dosare tutti gli elementi sopra menzionati |
