3925480647?profile=RESIZE_710xThe assessment of durum wheat geographical origin is an important and emerging challenge, due to the added value that a claim of origin could provide to the raw material itself, and subsequently to the final products (i.e. pasta). As an alternative to the use of stable isotopes and trace elements to determine geographic origin, Italian researchers used non-targeted high resolution mass spectrometry (LC-HRMS) to select chemical markers related to the geographical origin of durum wheat. Durum wheat samples from the 2016 wheat harvest were used to set up the model and to select the markers, while samples from the 2018 harvest were used for model and metabolomic markers validation. Different geographies across different continents were used in the sample set, so that it is now possible to discriminate between Italian, European and Non-European durum wheat samples.
