Abstract

The bio-active compounds present in food and beverages have a high potential influence on the future health of humans. The levels of biogenic amines, anthocyanins, polyphenols and antioxidant activity were measured in white (Pignoletto) and red (Sangiovese) grape berries and wines from the Emilia-Romagna region (Italy) obtained following conventional, organic and biodynamic agricultural and oenological practices. No significant difference was shown among the samples coming from different agricultural and winemaking practices. Principal Component Analysis was also performed. Biogenic amine amounts were higher in red than in white berries, while in the wines an opposite trend was observed, with histamine, tyramine and putrescine being the most abundant in Pignoletto wines. Red grapes and wines were richer in anthocyanins and showed higher antioxidant activity than white ones. The total level of polyphenols was similar in red and white berries, but with different metabolite profiles depending on the grape variety.
