Resumen
O objetivo deste estudo foi avaliar a qualidade microbiológica de castanhas industrializadas e das castanhas artesanalmente processadas, comercializadas por ambulantes em Teresina (PI). Foram coletadas 40 amostras de castanhas, sendo 21 amostras de castanhas industrializadas de três marcas (“A”, “B” e “C”) e 19 amostras de castanhas processadas artesanalmente (“D”), nas quais foram realizadas a determinação de coliformes a 35 °C e a 45 °C (NMP/g), a pesquisa de Salmonella spp. e a contagem de fungos. As amostras da marca “D” apresentaram maiores valores de coliformes a 35 °C (1,16 × 101 NMP/g); para coliformes a 45 °C, foram detectados valores de 7,0 NMP/g, e de 1,22 × 102 UFC/g para fungos e leveduras. Nas amostras da marca “A”, os valores para coliformes a 35 °C e 45 °C foram de 4,0 NMP/g e, para fungos e leveduras, de 1,0 × 102 UFC/g. Foram isoladas 43 cepas fúngicas. Do gênero Aspergillus, houve maior prevalência da espécie Aspergillus niger agregados (64,7%), e as espécies P. corylophillum (33,3%) e P. citrinum (29,2%) do gênero Penicillium. As amostras de castanhas industrializadas e processadas artesanalmente apresentaram condições higiênico-sanitárias satisfatórias e de acordo com a legislação vigente.
This study evaluated the microbiological quality of industrialized and handmade cashew nuts sold by street sellers in Teresina, PI. Forty samples of cashew nuts were collected, being 21 samples of industrialized products from three brands (“A”, “B” and “C”) and 19 samples of handmade nuts (“D”), which were analyzed on coliforms enumeration at 35 °C and 45°C (MPN/g), Salmonella spp. isolation, and fungi and yeasts counting. Samples of brand “D” showed the highest coliforms counting at 35 °C (1.16 × 101 MPN/g);values of 7.0 MPN/g were found for coliforms at 45 °C, and of 1.22 × 102 CFU/g for fungi and yeasts. In the brand “A” samples, values of 4.0 MPN/g for coliforms at 35 °C and 45 °C, and of 1.0 × 102 CFU/g for fungi and yeasts were detected. Forty-three fungi strains were isolated. The mostly prevalent specieswerethe aggregated Aspergillus niger (64.7%), P. corylophillum (33.3%) and P. citrinum (29.2%). The samples of industrialized cashew nuts and the handmade nuts showed satisfactory hygienic and sanitary conditions in compliance with the legislation in force.
