PMID 25777369

Abstract

In this study a total of 522 samples were collected from Shandong province of China in 2014 and analysed for the occurrence of fumonisin B1 (FB1), FB2 and FB3 by isotope dilution ultrahigh performance liquid chromatography-tandem mass spectrometry. Fumonisins were detected in 98.1% of the corn products, with the average total level of 369.2 μg kg(-1). The individual average values of FB1, FB2 and FB3 in corn products were 268.3, 53.7 and 47.2 μg kg(-1), respectively. The simultaneous occurrence of FB1, FB2 and FB3 was observed in 76.7% of the corn products. Especially, the results demonstrated that the difference in the contamination levels for fumonisins in these three types of corn products was apparent. In addition, 6.2% of the wheat flour samples were contaminated with FB1, with concentrations ranging from 0.3 to 34.6 µg kg(-1). No FB2 or FB3 was detected in wheat flour. In corn oil samples no fumonisins were detected.
