A. da  aQuality of Brazil nuts stored in forced aeration silos.h[electronic resource]  c2016  aThe traditional system of collection and storage of Brazil nut compromises seriously the quality of these almonds as it contributes to the high incidence of contaminants, like fungi of the genus Aspergillus, which can produce aflatoxins. In this study, the objective was to evaluate the influence of the storage period in studied conditions, on the physicochemical characteristics and on the microbiological contamination of Brazil nuts. The experimental was designed as completely randomized, considering as treatments the storage period (0 - control, 30, 60, 90, 120 and 150 days) with four replicates of 3 kg of Brazil nuts each. The samples were submitted to physicochemical and microbiological analysis. It was observed that almonds submitted to the storage had their moisture content reduced by 78.2% at 150 days of storage, however, this reduction was not fast enough to avoid surface contamination by filamentous and potentially aflatoxins producing fungi. The critical period of contamination occurred on the first 30 days of storage when there was an increase of the studied fungi, as well as B1 and total aflatoxin. The studied storage conditions were four times more effective in reducing the product moisture content than the traditional methods, however, pre-drying is necessary to avoid contamination of the product.  aAflatoxins  aAspergillus  aBrazil nuts  aFruit quality  aFungi  aPostharvest diseases  aSilos  aStorage quality  aAflatoxina  aArmazenamento  aBertholletia excelsa  aCastanha do pará  aContaminação fúngica  aDoença de planta  aFruto  aFungo  aQualidade  aSilo aéreo  aAeration silos  aAflatoxinas  aCalidad de almacenaje  aCalidad de la fruta  aCastanha do brasil  aEnfermedades postcosecha  aNuez del Brasil1 aALVARES, V. de S.1 aNOGUEIRA, R.
