Queijo Prato com teor reduzido de gordura adicionado de enzima proteolítica: características físicas e sensoriais

The Prato cheese is the second most consumed cheese in Brazil. It is produced by milk enzymatic coagulation, and maturated for at least 25 days; it is classified as fatty cheese and of medium moisture. Due to the concern to health, the cheeses consumers have been seeking for products with low fat contents; however fat is essential for providing desirable sensory and physiologic characteristics, such as flavor, softness and texture to cheeses. Alterations on the technological processing of low fat cheeses have been made seeking for improved products, and the use of proteolytic enzymes has been a significant strategy. The meltability, color and sensory characteristics are fundamental quality indicators of the final products. This study reports the findings from the analyses on the physical and sensory characteristics of low fat Prato cheese with addition of proteolytic enzyme – fastuosain, that is extracted from unripe gravata fruit. The addition of fastuosain improved the quality of the product, as this additive neither affected the meltability, nor produced bitterness, which is a common unpleasant taste in low fat cheeses.

Características dos substratos na absorção de nutrientes e na produção de gérbera de vaso

The production systems on substrates have been employed in most commercial cultivation of flowers and ornamental plants, including gerbera. However, its introduction as potted flower is recent in Brazil and many studies, especially those related to the determination of substrates physical and chemical properties, which contribute to production quality are still needed. The present study aimed to assess the influence of substrates characteristics for nutrient absorption and production of potted gerbera. The experiment was carried out in greenhouse with the experimental design in randomized blocks, factorial arrangement 5x2 (5 substrates and 2 cultivars) and 4 replications. Treatments consisted of substrates with different physical and chemical characteristics and gerbera cultivars (Cherry and Red). Plants grown on substrate with pH above 7.0 had a reduction in iron absorption, resulting in lower intensity of green coloration in the leaves. Plants grown on substrate with pH below 5.0 showed toxic levels of manganese and lower dry mass. The characteristics of the substrate, especially the pH, influence the nutrients absorption and the production of potted gerbera, altering the final plant quality.

Desenvolvimento de bebida láctea potencialmente probiótica carbonatada: características físico-químicas, microbiológicas e sensoriais

The goal of this work was to develop a strawberry fl avored dairy beverages carbonated and fermented with potential probiotic bacteria. Four formulations of dairy beverages were elaborated: Control (BL); Fermented (BLF); Carbonated (BLC) and Carbonated Fermented (BLFC). In samples submitted for carbonation, a carbonator was used for the carbon dioxide (CO2 ) gas injection dissolved in drinking water and the cultivation consisting of lactic bacteria Lactobacillus acidophilusLA-5®, Bifi dobacterium BB-12® and Streptococcus thermophilus (Biorich, Chr. Hansen) was employed on the fermented samples. The samples were characterized by physical and chemical, microbiological and sensory parameters. The BLC sample showed the presence of yeasts and coliform counts, but the counts indicated that it was suitable for consumption in 28 days time. The BL presented average coliform counts above the limit established by the law after 21 days of refrigerated storage. The presence of lactic bacteria and CO2 and their effects on lower proteolysis indexes, lower pH values and higher acidity values were correlated with signifi cant inhibitory effect of contaminated microorganisms in the BLF and BLFC. The carbonation was not stimulatory for the growth of lactic crops, mainly in the genus Bifi dobacterium spp. and Streptococcus spp. The BLF drink presented greater sensory acceptance and purchase intention test results, however the carbonated beverage presented positive results, with mean values greater than 50% in the acceptance tests with potential inclusion as sensory differential in dairy beverages. Just BLFC drink was considered potentially probiotic, by presenting minimum counts of Lactobacillus spp. during storage. Further studies should be conducted with the technology of carbonation, since it has been proven the correlation of the presence of CO2 with inhibitory effect of contaminated microorganisms and lower physical and chemical changes of dairy beverages.

Características agronômicas e demanda energética de cultivares de soja sob efeito dos sistemas de preparo do solo

The aim of this study was to evaluate the influence of preparation: intermediate grade, minimum tillage and no-till on the agronomic characteristics and energy demand of transgenic soybean cultivars and non-GMO soybeans. Soil preparation aims at improving physical, chemical and biological conditions, aiming at good emergence and plant development. The different types of tillage may interfere with the agronomic characteristics and productivity of plants, and in energy use which can cause variation in production costs. Genetically modified plants can be one of the alternatives for reduction of production costs in crops by reducing pesticide applications, enabling higher productivity with less environmental impact. The test was conducted in 2010/2011 at the agricultural Experimental Farm Lageado, belonging to the Faculty of Agronomic Sciences – UNESP, located in the city of Botucatu, SP in an area using no-till systems for the past 12 years. The experiment was carried out in a 3 x 2 factorial, randomized treatments were comprised of three soil preparation systems, minimum cultivation, intermediate grade preparation and no-till, with two cultivars of soybeans: MGBR-46 Conquest (conventional), Valuable RR (Transgenic). The data obtained was submitted to variance analysis using Tukey test at a 5% probability. With the results analyzed it might be observed that there was no significant difference between treatments, in the variables, the percentage of soil cover, final soybean plant population, grain yield and plant height. The results obtained show that the no-till system resulted in higher productivity than conventional tillage and minimum cultivation. The higher specific energy use per area was observed in minimum cultivation with a chisel plough, when compared to the preparation across the grid. The greatest fuel consumption was to treat minimum cultivation with chisel plough. The highest values were found in the skating system of minimum cultivation, being greater in conventional tillage system. It is more satisfactory for the producer to sow transgenic soy using a no-till system, because productivity retrieved from that system compensates for fuel expenditure.

Hábitos de actividad física en mujeres con discapacidad: relación con sus características físicas y funcionales.

[ES] El presente estudio tuvo como objetivo indagar las características de la mujer con discapacidad y su relación con los hábitos físico-deportivos que posee. Para ello, se aplicó la encuesta de Hábitos de Actividad Física en Personas con Discapacidad a una muestra de 132 mujeres con diferentes tipos de discapacidad y se tuvieron en cuenta diferentes características de discapacidad, así como dificultades funcionales. Los resultados obtenidos mostraron que la discapacidad física fue la más común, que existe un porcentaje importante de mujeres que no practica actividad física y que existe relación entre los días practicados y el IMC de la persona.

Características físico-químicas y aptitud agronómica de aguas subterráneas período 1997-2001 (Mendoza-Argentina)

El objetivo del presente estudio fue establecer las características físico-químicas y la aptitud agronómica de aguas subterráneas de la Provincia de Mendoza, correspondientes a perforaciones realizadas en el período 1997/ 2001. Se analizaron 206 muestras de aguas subterráneas provenientes de 15 departamentos de la provincia, para determinar -analíticamente o por cálculo- diversos parámetros fisicoquímicos y de aptitud agronómica. El 90 % de las aguas estudiadas resultó apto para el riego de todo tipo de cultivos y fue considerado de buena calidad de acuerdo con los criterios utilizados. En el Este de la provincia, debido a la contaminación de los acuíferos superficiales, se determinó que se requiere mayor profundidad para acceder a calidades aceptables. Los departamentos de Tupungato, Tunuyán y San Carlos, del Valle de Uco, poseen las aguas de mejor calidad, sobresaliendo Tunuyán. Excluida dicha zona, la mayor aptitud agronómica del agua se detectó en Maipú, mientras que la peor la detentan los departamentos de La Paz y General Alvear.
