A STUDY TO CHARACTERIZE QUALITY AND TO IDENTIFY GEOGRAPHICAL ORIGIN OF LOCAL VARIETIES OF SWEET PEPPER FROM PIEDMONT (ITALY)
Italy has the highest number of European protected denominations as concern fresh produce and there is a strong demand from producers and organized supply chains for tools that can assure the quality and origin of the certified products. Pepper is one of the most important vegetable products grown in different Italian areas as Piedmont Region, and some local varieties (Corno and Cuneo) have been widely recognized for their peculiar quality characteristics, thus receiving a protecting label. To better characterize such varieties of peppers, a three years project Capsiqual, financed by the Region, is aimed to characterizes quality, yield and nutritional features of traditional varieties of pepper from Piedmont and to test different analy¬tical techniques to identify geographical origin. Several analytical techniques (non destructive and destructive) have been utilized to characterize the products, reaching morphometric data (i.e. fruit size and pericarp thickness), qualitative data (sugar, acid and antioxidant content, volatile organic compounds composition by Electronic Nose analysis), and spectroscopic data (FT-NIR and Spectrofluorimetry). Preliminary results, reached during the first year of the project, relative to chemical, nutritional and morphometric characterization, pointed out on the peculiar quality character¬istics of varieties and good results are obtained to test Electronic Nose as tool for geographical origin identification.
