Characteristic biogenic amine composition of Tokaj aszu-wines

The biologically active airlines of grapes, aszu-grapes, aszu-wines of Tokaj region were analysed to study the effect of Botrytis cinerea oil the gapes. It was established that grapes contained mainly spermidine, putrescine and spermine, however, in the aszu-grapes new amine compounds such as agmatine, phenethylamine, butylamine and pentylamine isomers appeared. The spermine content showed an increase in all aszu-grape varieties compared to the grapes. During winemaking processes, spermine disappeared and die concentration of tyramine increased in the aszu-wines. The concentration of spermidine decreased during the ageing of the product. The ratio of tyramine mid airline content of the samples were found to be within a limited interval.
