Abstract
|
|
|
Eleven mycotoxins, including aflatoxins, ochratoxin A, fumonisins, zearalenone, T-2 toxin, deoxynivalenol, and
HT-2 toxin, were analyzed simultaneously in rice, barley, and maize produced in 2011 by liquid chromatography coupled
with triple quadrupole mass spectrometry (LC/MS/MS). Limits of detection (LOD) are 0.2 μg/kg for aflatoxin B1, and G1,
0.3 μg/kg for aflatoxins B2, and G2, 0.1 μg/kg for ochratoxin, fumonisins, zearalenone, and T-2 toxin and 3.0 μg/kg for
deoxynivalenol and HT-2 toxin. Limits of quantification (LOQ) were 0.6 μg/kg for aflatoxins B1, and G1, 0.9 μg/kg for
aflatoxins B2, and G2, 0.3 μg/kg for ochratoxin, fumonisins, zearalenone, and T-2 toxin and 10.0 μg/kg for deoxynivalenol
and HT-2 toxin. Recoveries for 11 mycotoxins ranged from 70.45 to 111.11%. Fumonisins, deoxynivalenol, and
zaeralenone were detected from 0.9 to 334.0 μg/kg in the polished rice, barley and raw corn cultivated in Korea. Other
mycotoxins were not detected. Deoxynivalenol contamination was mainly found in barley (24 out of 43 samples) and the
average value in positive samples was 113.30 μg/kg.
