Abstract
Este trabalho teve como objetivo avaliar a qualidade de castanhas-do-brasil beneficiadas e comercializadas em Rio Branco, Acre. Foram analisadas amostras das três marcas de castanha encontradas no mercado local quanto às variáveis: atividade de água, teor de umidade, contagem total de fungos filamentosos, quantificação de Aspergillus flavus e de A. parasiticus, bem como quantificação de aflatoxinas B1, B2, G1 e G2. As castanhas do comércio se encontravam com um teor de umidade e atividade de água adequados, o que pode ter sido responsável pela baixa contaminação por fungos e por aflatoxinas. Quanto a estas micotoxinas, as amostras estão de acordo com o recomendado pela Anvisa, podendo ser esta uma consequência da grande divulgação no Estado do uso de Boas Práticas no manejo da castanha.
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.
