Aflatoxins and fumonisins in feed from a broiler operation system from São Paulo state, Brazil Ciência Rural
Kobashigawa,Estela; Corassin,Carlos Humberto; Franco,Larissa Tuanny; Uliana,Rômulo Dutra; Oliveira,Carlos Augusto Fernandes de.
ABSTRACT: The aim of the present study was to assess the occurrence of aflatoxins (AFs) and fumonisins (FBs) in feed ingredients (corn and soybean meal) and finishing feed in a broiler operation system, as well was to evaluate their effect on the productivity of 20 batches of broilers produced and the histology status of broilers’ liver after slaughter. Corn samples presented the highest frequencies of AFs and FBs, at mean levels of 29.1 and 2,100µg/kg, respectively. Soybean samples presented mean levels of 1.5 and 70µg/kg for AFs and FBs, respectively. Batches of broilers receiving feed containing FB levels higher than 1,000µg/kg had lower weight gain and higher mortality rates, while those fed rations with AFs equal or above the limit of quantification...

Comparison of methods by TLC and HPTLC for determination of aflatoxin M1 in milk and B1 in eggs Ciênc. Tecnol. Aliment.
Scussel,V. M..
Milk and egg matrixes were assayed for aflatoxin M1 (AFM1) and B1 (AFB1) respectively, by AOAC official and modified methods with detection and quantification by thin layer chromatography (TLC) and high performance thin layer chromatography (HPTLC). The modified methods: Blanc followed by Romer, showed to be most appropriate for AFM1 analysis in milk. Both methods reduced emulsion formation, produced cleaner extracts, no streaking spots, precision and accuracy improved, especially when quantification was performed by HPTLC. The use of ternary mixture in the Blanc Method was advantageous as the solvent could extract AFM1 directly from the first stage (extraction), leaving other compounds in the binary mixture layer, avoiding emulsion formation, thus...

In vitro ability of beer fermentation residue and yeast-based products to bind aflatoxin B1 BJM
Bovo,Fernanda; Franco,Larissa Tuanny; Rosim,Roice Eliana; Barbalho,Ricardo; Oliveira,Carlos Augusto Fernandes de.
This study aimed to verify the in vitro ability of beer fermentation residue (BFR) containing Saccharomyces cerevisiae cells and five commercial products that differed in the viability and integrity of S. cerevisiae cells to remove aflatoxin B1 (AFB1) from a citrate-phosphate buffer solution (CPBS). BFR was collected at a microbrewery and prepared by drying and milling. The commercial yeast-based products were as follows: inactive intact yeast cells from beer alcoholic fermentation, inactive intact yeast cells from sugarcane alcoholic fermentation, hydrolyzed yeast cells, yeast cell walls and active yeast cells. Adsorption assays were performed in CPBS spiked with 1.0 μg AFB1/mL at pH 3.0 and 6.0 for a contact time of 60 min at room temperature. Analysis...
