Survey of Biogenic Amines Contents in Commercial Beers

Fourteen commercial beers (eight domestic and six imported) were investigated for their biogenic amine contents. In all products, six biogenic amines, putrescine, cadaverine, tryptamine, , spermine, and tyramine, were detected at different contents among the products, with the spermine content being the highest. Contents of cadaverine and in domestic beers, and and tyramine in imported ones were not significantly different. Results indicate that continuous monitoring of biogenic amine levels in commercial beers is needed to maintain chemical safety and qualities.
