“…3 Approximately 40% of this production is exported and the main importers are the United States, Germany and Spain. 4,5 Harvest of Brazil nuts is performed mainly by under-privileged families, using little technology, which results in a high incidence of microbial contamination. 6 The high humidity and temperatures of the Amazon region in combination with the transport of the nuts in precarious trucks set up ideal conditions for fungal development.…”

ABSTRACT:For proper handling of a product knowledge regarding its water content is essential. To provide fast, inexpensive and reliable results, the direct evaporation method of water in oil bath (EDABO) has been proven to be a viable alternative, at all stages of production of the Brazil nut. Therefore, adaptation and validation of the EDABO method for the almonds was developed using ten lots, five for each stage, maintaining the water content range between 3.73 and 29.13% w.b, which is the typical water content range for the product from the collection phase until its final marketing. The oil bath temperatures tested were 150° C to 200° C, from 10 to 10° C for the adaptation step. The results thus obtained were compared with the water content recorded for the same batch employing the vacuum oven method as the standard. In the adaptation step the most suitable temperature range was set. Next, the method was validated to test for the precision, accuracy and linearity of the pre-set temperature range. During this step, temperature of 150° C were observed to ensured water content results consistent with those determined by the standard method. In the validation step the temperature of 150° C revealed precision, accuracy and linearity and were comparable to the standard method. Therefore, considering the technical aspects for implementation of this method, it was concluded that 150° C temperature was validated.

“…Considering the wide range of known mycotoxins, the aflatoxins are evaluated as those of greater importance in Brazil due to their toxic effects and the incidence and magnitude of their contamination of foods 8 . Aflatoxins B1, B2, G1 and G2 represent the main group of these toxins and are produced by the fungi Aspergillus flavus, Aspergillus parasiticus and Aspergillus nomius 9 . They are considered to be carcinogenic, mutagenic, immunosuppressive and teratogenic 10 .…”

The objective of this study was to detect the presence and levels of aflatoxins in Brazil nuts. The results showed that of a total of 84 Brazil nut samples (25 kg), 11 (13.1%) were found to be positive for aflatoxin using thin layer chromatographic analyses. Of the aflatoxins found, aflatoxin B1 was the most commonly found mycotoxin (n = 6, 7.2%) at the collection points evaluated. With respect to the samples evaluated by the enzyme linked immunosorbent assay, 35 (41.7%) were shown to be positive. The average level of contamination of the Brazil nuts by total aflatoxins was 6.24 µg/kg ± 5.29, the lowest value being 0.7 µg/kg and the highest 28 µg/kg, and three samples were shown to be above the limit permitted by Brazilian and European legislation. Regarding the influence of the variables of temperature and air humidity on the production of aflatoxins according to the seasonal variations of the dry and rainy periods, no statistically significant correlation could be found. The results obtained indicated the need to monitor the contamination of nuts by aflatoxins and develop strategies to guarantee the adoption of good handling practices as a contribution to assuring the quality and safety of these foods.
