Qualidade da castanha-do-brasil do comércio de Rio Branco, Acre

the goal of this paper was to evaluate the quality of brazil nuts processed and marketed in the city of rio branco, in the state of acre (brazil). we analysed three samples for water activity, moisture content, total fungus quantification of aspergillus flavus and a. parasiticus, as well as quantification of total aflatoxin, afla b1, afla b2, afla g1 and afla g2. the nut samples from the market showed an appropriate moisture content and water activity, which may have been responsible for the low fungus contamination and aflatoxin production. as to these mycotoxins, the samples were consistent with anvisa's recommendations, which may be a consequence of good management of the nuts in acre.
