Testing Deoxynivalenole (DON) Determination Techniques in Bread Products

摘要

Deoxynivalenole (DON) or vomitoxin, mainly produced by Fusarium graminearum have high occurrence within Romanian space, mainly in wheat and triticale, and seldom in rhye and barley. Deoxynivalenole (DON) content was quantified in 198 white bread samples produced in Romania, during January 2013 - January 2015. Samples were collected from supermarkets from 11 towns. High performance liquid chromatography was used for laboratory analyze. The analyze of the results obtained from quantifications of the deoxynivalenole (DON) content in bakery products represented by white bread demonstrates that in three of origin areas,?? Alba Iulia, N??s??ud and Miercurea-Ciuc, respectively, the means of deoxynivalenole (DON) concentrations are smaller compared to allowed limits of 500 mg/kg, 300 ??g/kg, 140 ??g/kg and 102 ??g/kg, respectively. Concerning majority of analyzed areas, the white bread samples recorded moderate zearalenone content. Only white bread samples harvested from Braè?ov, recorded big deoxynivalenole (DON) concentrations, with a mean of 3100 ??g/kg.
