【 摘 要 】

The aim of this study was to evaluate the fate of fumonisins B1 (FB1) and B2 (FB2) during industrial dry-milling in two lots from 2014 (n = 120) and 2015 (n = 120) of non-transgenic corn and their fractions (germ, pericarp, endosperm, cornmeal and grits), collected from one of the major Brazilian milling industries. Fumonisins were concentrated in the germ and pericarp at a rate of 322% and 188% (lot 1) and 311% and 263% (lot 2), respectively. In the endosperm, cornmeal and grits fumonisin levels decreased from 60 to 95%. Fumonisin levels in cornmeal and grits were below the maximum limit tolerated by the European Commission. Therefore, corn industrial dry-milling can contribute to reducing fumonisin levels in corn products intended for human consumption. (C) 2016 Elsevier Ltd. All rights reserved.
