Ariane Mendonça PACHECO Ana LUCAS Rosana PARENTE Neuzimar PACHECO Agrociencias moisture Aspergillus Bertholletia chromatography Brazil nut has a high nutritional content and is a very important trade commodity to some Latin American countries. In order to evaluate its safety, 120 samples from different stages of the productive chain were analyzed in terms of: moisture content (mc), aflatoxigenic fungi and aflatoxin (LOQ = 1.95 μg.kg–1 total aflatoxin) using TLC. Among all samples, 4 (6.7%) from the receiving area, and 5 (16.7%), from retail presented aflatoxins above the LOQ, but the amount of aflatoxins was below the LOQ after the samples were dried in the plant. The positive samples were above the limit of total aflatoxin permitted by the European Union (4.0 μg.kg–1) and Brazil (30 μg.kg–1). The mc mean was 22.43% in the receiving area, which is higher than that in the other stages samples. All the A. flavus strains were aflatoxigenic, and there was statistic association between the presence of aflatoxin and flavus strains. The aflatoxigenic fungi strains associated to the aflatoxins levels in the samples show that an effective control is necessary for the food safety in the Brazil nut production chain. 2010 artículo científico 0101-2061 https://www.redalyc.org/articulo.oa?id=395940100007 en http://www.redalyc.org/revista.oa?id=3959 Ciência e Tecnologia de Alimentos application/pdf Sociedade Brasileira de Ciência e Tecnologia de Alimentos Ciência e Tecnologia de Alimentos (Brasil) Num.2 Vol.30 |
