Özet

The purpose of this study was to investigate fumonisin B-1 (FB1)- and B-2 (FB2)-contaminated corn and corn-based products consumed especially by the Turkish population. FB1 and FB2 were detected using high-performance liquid chromatography with fluorescence detection. The total number of commercially available corn and corn-based product samples analyzed in this research was 82. The recoveries were found to be 94.4 +/- 4.62% and 86.5 +/- 4.86% for cornmeal spiked with known amounts of FB1 and FB2 (1 ppm), respectively. The minimum detectable amount for the o-phthaldialdehyde derivatives of FB1 and FB2 were 1 ng and 5 ng. respectively. Detected levels of FB1 were between 0.25 ppm and 2.66 ppm in 25.6% of the samples, and detected level of FB2 in a single cornmeal sample was 0.55 ppm.
