Bio Genic Amines And Serotonin In Hungarian Wines Produced With Organic Yeast Starters

Recently, certified organic yeast starters have been put on the market, but most organic producers in Central Europe still prefer spontaneous fermentation. Biogenic amines, physiologically active compounds, are formed from precursor amino acids, partially by yeasts. In this study, two organic yeast starters were examined for biogenic amine production, in comparison with spontaneous fermentation. The biogenic amine profile showed considerable differences between the organic yeasts under investigation and spontaneous microbiota, but the biogenic amine production of the two organic yeasts was similar, except for tyramine and ethylamine. Significantly lower histamine and higher serotonin amounts were produced by the organic yeast starters compared with spontaneous fermentation. Organic yeast starters offer an opportunity for organic producers instead of spontaneous fermentation, to ensure the quality and safety of their products in regard to biogenic amines.
