Biogenic amine determination in wine fermented in oak barrels: Factors affecting formation

2008

Changes in biogenic amines (histamine, putrescine, tyramine and cadaverine) were monitored during the industrial production of Tempranillo and Cabernet Sauvignon wines. The origin of these amines in relation to the presence of different lactic bacteria (indigenous or inoculated) during malolactic fermentation, while aging in oak barrel, and the correlations between amines and their corresponding amino acids were statistically evaluated. In this study we found that there was a greater increase in amines post malic acid depletion than during malolactic fermentation and that more amines were produced in wine of the Tempranillo variety. The total amino acid concentration was 1.6 times greater i…
