| Resumo: |
Aflatoxins, fumonisins and zearalenone take part of the most studied mycotoxin groups due to their toxic effects on animal and human health. This research evaluated samples of soybeans meal used in animal food industry. A hundred and twenty one soybean meal samples were analyzed, so that 66 were analyzed before the industrial processing of micronization and 55 after it. The bromatological average of samples before micronization showed the following answers: 12.4% moisture; 46.4% protein; 79.5% protein solubility; 5.9% ash content; 2.2% fat; 4.3% fiber and 0.02 (ΔpH) of urease activity. The samples of micronization soybean meal showed 7.0% average values for moisture and 48.6% for crude protein. The mycotoxin levels were low in natura soybean meal; therefore, average values were 0.5μg kg-1, 29.6μg kg-1 and 56.8μg kg-1 for aflatoxin, zearelenone and fumonisin, respectively. After micronization, the average values for the studied samples were 1.3μg kg-1, 67.5μg kg-1 and 89.1μg kg-1, respectively for the same mycotoxins. The results for bromatological and mycotoxin analyses indicate similarity with the established patterns according to the Brazilian Compendium for Animal feed and reference literature. However, at least one of the three studied mycotoxin was detected in all of the analyzed samples and there was greater contamination of soybeans meal after the micronization process.
