Study of different biogenic amines in wines from two protected designations of origin (PDOs) in Murcia (Spain) multivariate classification

Abstract

Aims: Biogenic amines were determined in 109 wines from two wine-producing areas (Jumilla and Bullas PDOs) situated in the Murcia region (SE Spain). Methods and Results: Biogenic amines (histamine, ethylamine, tyramine, phenylethylamine, putrescine, tryptamine and cadaverine) were analysed by RP-HPLC with o-phthaldialdehyde precolumn derivatization and fluorescence detection. Histamine and putrescine were the most prevalent amines in Jumilla wines (49 and 48%, respectively), whereas tryptamine and putrescine were the most prevalent ones in Bullas wines (19 and 38%, respectively). Multivariate analyses were used to attempt a preliminary classification of wines according to production area. Conclusion: In general, wines from Jumilla PDO had a higher biogenic amine content than wines from Bullas PDO; however, all of them were safe from the health point of view. Significance and impact of the study: This study demonstrates that the Jumilla and Bullas wines studied are safe to drink and that geographical classification based on biogenic amine profiles is not possible with the analysed samples.
