Fatores que interferem durante o processo de fermentação natural das fatias de cubiu

This study aims to assess the effects of natural fermentation on the physical, physic-chemical and microbiological cubiu. Ripe cubiu undergone selection, peel, cut into four pieces, seeds removed and the slices were divided into two lots. One batch was subjected to blanching by immersion in water for 1 minute at 95 ° C and immediately bathed in ice water. Both were subjected to natural fermentation with increasing concentrations (2, 4, 6 and 8%) NaCl and 24 h time of immersion in each concentration. The process was monitored by moisture, pH, total acidity, sodium chloride, pectin and texture of the slices of cubiu. In relation to fresh fruit, money not increase the moisture and pH, decrease in total acidity and sodium and chloride did not significantly alter the texture. During the process of natural fermentation parameters moisture, acidity, texture and pH (control) were reduced from their values for pH (bleached) and sodium chloride was no increase in the values. The natural fermentation process was detected during the immersion of slices of cubiu pre treated or not in NaCl solutions. The physical and physic-chemical properties of slices cubiu were modified during the natural fermentation process, being more pronounced in slices.O objetivo foi avaliar os efeitos da fermentação natural nas características físicas, físico-químicas e microbiológicas do cubiu. Frutos maduros passaram por seleção, descasque, corte em quatro partes, retirada das sementes e as fatias foram divididas em dois lotes. Um dos lotes foi submetido ao branqueamento por imersão durante 1 minuto em água a 95° C e imediatamente em banho de água com gelo e outro lote não tive branqueamento. Ambos foram submetidos à fermentação natural com concentrações crescentes (2, 4, 6 e 8 %) de NaCl e tempo de 24 h de imersão em cada concentração. O processo foi monitorado pelas análises de umidade, pH, acidez total, cloreto de sódio, textura e pectina das fatias do cubiu. Em relação ao fruto in natura, o branqueamento acarretou aumento da umidade e pH, decréscimo da acidez total e do cloreto de sódio e não alterou significativamente a textura. Durante o processo de fermentação natural os parâmetros umidade, acidez total, textura e pH (controle) sofreram redução, para pH (branqueadas) e cloreto de sódio houve acréscimo. O processo de fermentação natural foi detectado durante a imersão das fatias do cubiu pré tratado ou não em soluções de cloreto de sódio (NaCl). As características físicas e físico-químicas das fatias de cubiu sofreram modificações no processo de fermentação natural, sendo mais acentuadas nas fatias pré tratadas

Calidad de la leche cruda para consumo humano en dos localidades de Sucre (Colombia)

Objective. To determine the physicochemical, microbiological and somatic cell count of raw milks marketed for human consumption in neighborhoods of Sincelejo and Corozal (Sucre). Materials and methods. A cross-sectional study was carried out in 97 samples of raw milk marketed for human consumption in different neighborhoods of Sincelejo and Corozal (Sucre). Physical-chemical, microbiological and somatic cell count parameters were determined. The data obtained were analyzed according to the regulations in normative measures in Colombia. Results. Most of the physical-chemical parameters of the raw milk samples analyzed were found within the normal range according to Colombian legislation. Mesophilic count and somatic cells count was found to be above what is allowed by the legislation. The presence of total and fecal coliforms, antibiotics and adulterants such as sucrose and starches were determined. Conclusions. Raw milks distributed for human consumption in Sincelejo and Corozal presents good physical-chemical quality but poor microbiological quality; it becomes necessary to increase surveillance and to demand the production of excellent quality milk in the primary sector in the dairy chain.Objetivo. Determinar la calidad fisicoquímica, microbiológica y recuento de células somáticas de leches crudas que se distribuyen para consumo humano en diferentes barrios de Sincelejo y Corozal (Sucre). Materiales y métodos. Mediante un estudio descriptivo de corte transversal, se tomaron 97 muestras de leche cruda; se determinaron algunos parámetros fisicoquímicos, microbiológicos y recuento de células somáticas. Los datos obtenidos se analizaron de acuerdo a la normatividad vigente en Colombia. Resultados. La mayoría de los parámetros fisicoquímicos de las muestras de leche cruda evaluadas se encontraron dentro de los parámetros normales de la legislación colombina. El recuento estándar en placa y el recuento de células somáticas se encontraron por encima de lo permitido por la legislación. Se demostró la presencia de coliformes totales, coliformes fecales, antibióticos y adulterantes como sacarosa y almidones. Conclusiones. La leche cruda que se distribuye para consumo humano en  Sincelejo y Corozal presenta  buena calidad fisicoquímica pero deficiente calidad microbiológica; se hace necesario incrementar la vigilancia y exigir al eslabón primario de la cadena láctea la producción de leche de excelente calidad
