Quantitative determination of ochratoxin A in wine after the clarification and filtration

Through the use of the analytical method known as HPLC-FD and previously used the method for extraction of ochratoxin A by immunoaffinity columns, we have analyzed the possible effect of the clarification and filtration process on 54 samples of 2013 newly fermented wine, which have finished alcoholic fermentation process and racking, without knowing in advance whether there and how is the amount of OTA in wine. The racking of the wine before clarification and filtration followed by adequate clarification and filtration process during winemaking seems to be crucial in the reduction or complete elimination of the analyzed mycotoxin (OTA).The results of all analyzed samples have been below the limit allowed by the EU for ochratoxin A i.e. 2 ng/ml, and as such does not represent a risk to human health

QUANTITATIVE DETERMINATION OF OCHRATOXIN A IN WINE

Through the use of the analytical method known as HPLC-FD and previously used the method for extraction of ochratoxin A by immunoaffinity columns, we have analyzed 25 samples of 2013 newly fermented wine, which have just finished alcoholic fermentation process, 11 of which have been analyzed from different regions of Italy and 14 other samples from two regions of Kosovo. From the total number of samples, 24 samples were red wine and only one was white wine. The results of all analyzed samples have been below the limit allowed by the EU for ochratoxin A i.e. 2 ng/ml
