Determination of Mycotoxins in Bee Pollen by Gas
Chromatography-Tandem Mass Spectrometry
J Agric Food Chem, 2013 Feb 5
Bee pollen, promoted as natural food supplement, is consumed
increasingly by people to maintain a healthy diet. Depending on environmental
conditions pollen can also be an optimum medium for growth of molds such as
Fusarium, Penicillium. A quick, easy, cheap, rapid and safe (QuEChERS)
extraction procedure followed by a gas chromatography-tandem mass spectrometry
(GC-MS/MS) determination of eight selected Fusarium toxins in bee pollen was
developed and optimized. Recovery studies at 20, 80 and 1000 µg/kg showed
values between 73 and 95% with relative standard deviations (RSDs) lower than
15% for all studied mycotoxins. Limits of quantitation (LOQ) ranged from 1 to 4
µg/kg. The proposed method was applied to the analysis of 15 commercial
samples. Two out of fifteen samples showed quantifiable values for neosolaniol
and nivalenol.
