Resumo: | The in natura pulp of the buriti tree (Mauritia flexuosa L.) is widely consumed in the northern and northeastern states of Brazil. However, there are few studies related to the quality control of these food products. The objective of this study was to evaluate the physical-chemical properties and microbiological quality of buriti pulp commercialized in Manaus-Amazonas. The samples were collected in fairs in the northern (ZN), southern (ZS), eastern (ZL), western (ZO), central-western (ZCO) and central-southern (ZCS) areas of the city. The pulps were evaluated for pH, ash, titellable acidity expressed in citric acid, total soluble solids expressed in ºBrix and ratio. To determine the microbiological quality, coliforms at 45 °C, Escherichia coli, Salmonella sp. and molds and yeasts were detected. The pH ranged from 3.26 to 3.03 and sample ZL2 presented significant amounts of ash (3.0%). Expressive values of total soluble solids (°Brix) were determined in samples ZCS1 (4.68) and ZL2 (4.64). The average acidity expressed in citric acid and the ratio were 0.36 g.100-1 and 9.10, respectively. The pulps presented high mold and yeast contamination, with significant count (9 x 103 CFU/g) determined in sample ZS1. The growth of coliforms at 45 °C,E. coli and Salmonella sp. was not observed. The results obtained in this study indicate the need for improvements in the quality control of fresh fruit pulps sold at fairs in the capital of Amazonas. |

Sin embargo, existen pocos estudios relacionados con el control de calidad de estos productos alimenticios. El objetivo de este estudio fue evaluar las propiedades físico-quimicas y la calidad microbiológica de la pulpa de buriti comercializada en Manaus-Amazonas. Las muestras se recolectaron en ferias de las zonas norte (ZN), sur (ZS), leste (ZL), oeste (ZO), centro-oeste (ZCO) y centro-sur (ZCS). Las pulpas han sido evaluadas para pH, cenizas, acidez titulable expresada como ácido cítrico, sólidos solubles totales expresados como ºBrix y la relación SST/Acidez. En la determinación de la calidad microbiológica, la presencia de coliformes a 45 ° C, Escherichia coli, Salmonella sp. y mohos y levaduras. El pH ha oscilado entre 3,26 y 3,03 y la muestra de ZL2 ha presentado una cantidad significativa de cenizas (3,0%). Los valores expresivos de sólidos solubles totales (° Brix) se determinaron en las muestras ZCS1 (4.68) y ZL2 (4.64). La acidez media expresada como ácido cítrico y la relación SST/Acidez 0,36 g.100-1 y 9,10, respectivamente. Las pulpas han demonstrado alta contaminación por mohos y levaduras, con un recuento significativo (9 x 103 UFC / g) determinado en la muestra ZS1.

Los resultados obtenidos en este estudio han indicado la necesidad de mejoras en el control de calidad de las pulpas frescas comercializadas en ferias de la capital del estado de Amazonas.A polpa in natura do buriti (Mauritia flexuosa L.) é bastante consumida nos estados da região norte e nordeste do Brasil. Porém, há poucos estudos relacionados ao controle de qualidade desses produtos alimentícios. O objetivo desse estudo foi avaliar as propriedades físico-químicas e a qualidade microbiológica de polpas de buriti comercializadas em Manaus-Amazonas. As amostras foram coletadas em feiras das zonas norte (ZN), sul (ZS), leste (ZL), oeste (ZO), centro-oeste (ZCO) e centro-sul (ZCS) da cidade. As polpas foram avaliadas quanto ao pH, cinzas, acidez titulável expressa em ácido cítrico, sólidos solúveis totais expressos em ºBrix e ratio. Na determinação da qualidade microbiológica foram avaliadas as presenças de coliformes a 45 °C, Escherichia coli, Salmonella sp. e bolores e leveduras. O pH variou de 3,26 a 3,03 e a amostra ZL2 apresentou quantitativo significativo de cinzas (3,0%). Valores de expressivos de sólidos solúveis totais (°Brix) foram determinados nas amostras ZCS1 (4,68) e ZL2 (4,64). A média de acidez expressa em ácido cítrico e do ratio foram de 0,36 g.100-1 e 9,10, respectivamente. A polpas apresentaram elevada contaminação por bolores e leveduras, com contagem significativa (9 x 103 UFC/g) determinada na amostra ZS1. Não foi observado o crescimento de coliformes a 45 °C, E. coli e Salmonella sp.
