Interpretive Summary:

Technical Abstract: The fate and distribution of the fumonisins B1 (FB1) and B2 (FB2) have been determined in products from ethanol fermentations and wet millings of naturally contaminated corn. Fumonisins are stable to the conditions used in ethanol fermentations and tend to concentrate in the distillers dried grain fraction generally used for animal feed. No toxin was found in the ethanol. Starch from wet milling of corn, naturally contaminated at 13.9 ug/g fumonisin B1, was free of detectable toxin. The other fractions contained fumonisins at the following levels: gluten (5.1-5.8 ug/g FB1, 4.7-4.9 ug/g FB2); fiber (2.7-5.7 ug/g FB1, 2.1-3.1 ug/g FB2); and germ (1.3-3.1 ug/g FB1, 0.7-1.6 ug/g FB2). The steep water and process water contained 22% of the recoverable fumonisins. A combination of analytical methodologies were required to determine fumonisins in the different products from the wet milling process.
