The objective of this study was to evaluate the replacement of part of the pork from Cuiabana sausage by a brewery by-product on the physicochemical and microbiological properties during storage. Brewery by-product (BW) concentration influenced sausage colouration, with reduced luminosity, L*: 52.060 in the 6% (w/w) treatment compared to the 0% treatment controls (L*: 63.956). Titratable acidity showed higher (1.162 g/100 g) compared to the 0% treatment controls (1.093 g/100 g) of lactic acid. Proteins and total enzymatic fibers increased, 19.068 and 9.233 g/100 g of sample respectively. It was observed that the by-product did not interfere in the oxidation of the lipids and the best model to describe the oxidation of lipids is Van Bertalanffy model (P 0.05). Escherichia coli and Staphylococcus sp. levels were within the prescribed limits and Listeria monocytogenes colonies were observed. The addition of by-products had no interference on the formation of oxidation compounds in the sausage and has increased fiber content.

This study aims to determine the commercial expiration date of and characterize lactose-free artisanal ice cream with dairy and non-dairy bases. We evaluated four ice cream with different bases at 0, 7, 14, and 21 d of storage. Their centesimal composition was analyzed for proteins, lipids, ashes, carbohydrates, and moisture. The physicochemical properties analyzed included overrun, density, titratable acidity, pH, water activity, and total soluble solids. The L*, a*, b*, C*, and h* parameters were used to evaluate color. Microbiological analyses included Salmonella sp., coagulase-positive Staphylococci, coliforms at 45° C, and mesophilic and psychrotrophic heterotrophic bacteria. Sensory analysis analyzed the consumer profile and measured their acceptance and intent to purchase the samples, with the zero-lactose milk base obtaining the best nutritional values, the best sensory characteristics, and more than 70% intent to purchase, indicating that it is the most accepted formulation. All treatments had a shelf life of 21 d at −18° C. Este trabajo tiene como objetivo determinar la vida útil comercial y caracterizar el helado artesanal sin lactosa a base de leche y no lácteos. Se evaluaron cuatro helados con diferentes bases a los 0, 7, 14 y 21 días de almacenamiento. Su composición próxima se analizó en busca de proteínas, lípidos, cenizas, carbohidratos y humedad. Las propiedades fisicoquímicas analizadas incluyeron resiliencia, densidad, acidez titulable, pH, actividad del agua y sólidos solubles totales. Se utilizaron los parámetros L *, a *, b *, C * yh * para evaluar el color. Los análisis microbiológicos incluyeron Salmonella sp., Estafilococos coagulasa positivos, coliformes a 45 ° C y bacterias heterótrofas mesófilas y psicrotróficas. El análisis sensorial analizó el perfil del consumidor y midió su aceptación e intención de compra de las muestras, obteniendo la leche cero lactosa los mejores valores nutricionales, las mejores características sensoriales y más del 70% de intención de compra, indicando que es la máxima redacción aceptada. Todos los tratamientos tuvieron una vida útil de 21 días a -18 ° C. Este trabalho tem como objetivo determinar o prazo de validade comercial e caracterizar sorvetes artesanais sem lactose à base de leite e não lácteos. Foram avaliados quatro sorvetes com diferentes bases aos 0, 7, 14 e 21 dias de armazenamento. Sua composição centesimal foi analisada para proteínas, lipídios, cinzas, carboidratos e umidade. As propriedades físico-químicas analisadas incluíram superação, densidade, acidez titulável, pH, atividade de água e sólidos solúveis totais. Os parâmetros L *, a *, b *, C * e h * foram usados ​​para avaliar a cor. As análises microbiológicas incluíram Salmonella sp., Staphylococci coagulase-positiva, coliformes a 45 ° C e bactérias heterotróficas mesofílicas e psicrotróficas. A análise sensorial analisou o perfil do consumidor e mediu sua aceitação e intenção de compra das amostras, com o leite à base de zero lactose obtendo os melhores valores nutricionais, as melhores características sensoriais e mais de 70% de intenção de compra, indicando que é o máximo formulação aceita. Todos os tratamentos tiveram uma vida útil de 21 dias a -18 ° C.

This study aimed to evaluate the effect of sucralose added in Greek Yogurt flavored with araticum (Annona crassiflora) and mangaba (Hancornia speciosa) through sensory characterization. The Greek yogurt was prepared with skimmed milk, inoculated starter cultures, filtered and it was supplemented with the appropriate amount of sucralose, added sweetened and pasteurized fruit pulp (araticum or mangaba). The total phenolic compounds and texture were performed and sensory analyses were carried out by Quantitative descriptive analysis (QDA) and acceptance test in storage for 7 and 28 days. The QDA results showed that the main attributes were color, lightness, creaminess, presence of particles, fullness, and aroma. Eighty percent and 85% of the panelists were said they would buy the araticum Greek yogurt and the mangaba Greek yogurt after 7 days of storage, respectively. Additionally, 71% and 77% were said they would buy the araticum Greek yogurt and the mangaba Greek yogurt after storage for 28 days at 4ºC, respectively. The sensory profile and acceptance test results of the Greek yogurts developed indicated no perceptions caused by adding sucralose to the yogurt after storage for different times. The highest concentration of phenolic compounds in the araticum Greek yogurt was perceived by the panelists in aroma and flavor attributes. Changing sucrose to sucralose was not imperceptible under the storage and consumption conditions.
