Abstract. Fourier transform near infrared (FT-NIR) spectroscopy, in combination with principal component-linear discriminant analysis (PC-LDA), was used for tracing the geographical origin of durum wheat samples. The classification model PC-LDA was applied to discriminate durum wheat samples originating from Northern, Central, and Southern Italy ( n = 181), and to differentiate Italian durum wheat samples from those cultivated in other countries across the world ( n = 134). Raman showed that, although most light reflected from a substance was the same color or wavelength, a small amount of light experiences a color or wavelength shift when it is reflected. Modern lasers made Raman spectroscopy viable as a technique for determining physical and chemical properties of materials (including geological materials).
