Near-infrared spectrocopy is suitable for the classification of hazelnuts according to protected designation origin

BACKGROUND: This study investigates the possibility of using Near-Infrared spectroscopy for the authentication of the 'Nocciola Romana' hazelnut (Corylus avellana L. cvs. 'Tonda Gentile Romana' and 'Nocchione') as a protected designation of origin (PDO) hazelnut from Central Italy. Algorithms for the selection of the optimal pretreatments were tested in combination with the following discriminant routines: […]
