A survey of biogenic amines in commercial Portuguese wines

With this work it was possible to conclude that most commercial Portuguese wines presented a low concentration of biogenic amines (<8 mg/l) and 25% of these wines presented contents lower than 2.5 mg/l. Tyramine and putrescine were biogenic amines present in a higher concentration. The wines from the Alentejo region showed highest concentrations of biogenic amines, especially in tyramine and histamine.
