Distribution of aflatoxins in contaminated corn fractions segregated by size BJM
Piedade,Fabiana S.; Fonseca,Homero; Glória,Eduardo M.; Calori-Domingues,Antonia; Piedade,Sônia M.S.; Barbin,Décio.
The efficiency of segregation, by particle size, in reducing the aflatoxin content of corn lots under the Brazilian conditions was studied. The aflatoxin content, in the corn fractions obtained after sieving thirty contaminated samples, with approximately 3.0 kg each, was determined. The samples were passed through 4.5 mm round-hole sieves and the fractions with particles ³4.5 mm (fraction A) and <4.5 mm (fraction B) and then analyzed for aflatoxins by TLC. The results showed that the distribution of the aflatoxins among the fractions A and B varied from sample to sample. However, the fraction B presented higher content (6 to 1,422 µg/kg) of aflatoxins (P<5%), than samples of fraction A (4 to 389 µg/kg). In spite of that the segregation of this...
