The effect of fertilizer to the biogenic amines concentration in wines

In the last few years food compounds which have a physiological effect (especially wine compounds) came to the front, therefore biogenic animes have gained on importance. In our experiment we determined - for oenological conditions important - histamine, tyramine and serotonin content with HPLC technique. Biogenic amines are produced from amino-acids (precursors) during the decarboxylation procedure. Commercial fertilizers and combinations were independent factors, and biogenic amine concentrations were observed as dependent factors (the Cserszegi ffiszeres samples, vintage 2015, were homogenous form in every aspects except the fertilizer usage under alcoholic fermentation=AF). After AF - thus after various fertilizer additions - considerable changes were shown in the amount of the investigated three compounds, although we could not find an obvious pattern. Histamine and tyramine were far away from the toxic limit, serotonin presence was slightly higher than in the earlier results, however serotonin is not a poisonous compound (positive evaluation), hence the ascent was not a problem
