摘要

One hundred (100) samples of corn-based food products were collected between February 2007 and July 2010 to estimate the intake of fumonisins in the state of Paran谩, Brazil. The identification of fumonisins was performed by high-performance liquid chromatography with fluorescence detection and post column o-phthaldialdehyde (OPA) derivatisation. The occurrences of fumonisins B₁ (FB₁) and B₂ (FB₂) were 82%and 51%, respectively, with concentrations ranging from 126 to 4348聽渭g/kg (FB₁聽+聽FB₂). Among corn-based products, corn meal had a higher prevalence of fumonisin (96.6%), and corn grits had the highest level of contamination (3462聽渭g/kg for FB₁ and 886聽渭g/kg for FB₂). The average probable daily intake (APDI) and maximum probable daily intake (MPDI) estimated for the population of Parana, Brazil, were 120.58 and 256.07聽ng/kg body weight/day, respectively, which is lower than the provisional maximum tolerable daily intake (PMTDI), 2000聽ng/kg body weight/day.
