The products were flavored and analyzed for global acceptance. The results showed significant effects of temperature and screw speed on the dependent variables. The chocolate flavored snacks obtained good acceptance.

Análise energética do novo sistema de produção de maracujá amarelo na região de Marília-SP

The study aimed to evaluate energy indicators of a new production system of yellow passion fruit in Marilia-SP. Analyzed the inputs of the biological energy, fossil and industrial and output energy in the form of fruits produced per unit area as well as five energy indicators. The input energy amounted 155,810.13MJ ha(-1). Chemical fertilizers and pesticides accounted for 71% and 24% of indirect energy industry, respectively. The activity generated per cycle / ha, 587.700.00MJ, and cultural productivity 0.19MJ kg(-1). The efficiency culture was 3.77. The cultural energy net totaled 431,889.87MJ ha(-1). The energy efficiency (4.17) and energy balance (550,312.91MJ ha(-1)) was favorable. It was concluded that the direct energy consumption from fossil fuels, even though significant, yet permits the production of the fruit of an environmentally sustainable manner. Chemical fertilizers and pesticides were the most representative of indirect energy industry due to the intensification of fertilization as a means of disease prevention.

Amplificação, clonagem e sequenciamento de promotores de café (Coffea arabica cv Mundo Novo) específicos de fruto e ubíquos

The Coffee Genome Project made available to the scientific community relevant information that made practical the identification and cloning of important genes, as well as the identification of the major sequences involved on their regulation. The aim of the present study was to amplify, clone and sequence coffee promoters with specific expression patterns. For that, coffee ESTs which known expression profiles were employed. First, the promoter regions of coffee genes showing, respectively, fruitspecific and ubiquitous expression were amplified using the Genome Walking strategy. Amplified sequences were then inserted in the pGEM-Teasy vector (Promega) and sequenced. Once completed the sequencing, an expression cassette was constructed using the binary vector pCAMBIA-1381z (Cambia). These expression cassettes were cloned into Agrobacterium tumefaciens, and transgenic tobacco plants were generated aiming the functional characterization of these promoters

Nutrição mineral e qualidade do fruto do abacaxizeiro e do maracujazeiro

Several factors influence the productivity and fruit quality of pineapple and passion fruit, among which are: climate, soil fertilization and irrigation practices. Mineral nutrition is essential to increase productivity and improve fruit quality; however, there is a few information about the effect of fertilization in these two fruit crops, especially under tropical conditions. The objective of this review was to compile the main research results, in which the influence of mineral nutrition on the fruit quality was evaluated. We considered the information recently published in scientific journals, and presented it for the macronutrients individually, then to NPK and, finally, the micronutrients. The review showed that it is difficult to say that some element favors or not certain characteristics of pineapple and passion fruit fruits, since the results are inconsistent and there is not many information. More than established the effects of mineral nutrients on the fruit quality of these two fruit crops, we stand out that research in this topic is very necessary.

Determinação do valor energético em bebidas de maracujá

The objective of this work was to calculate the energetic values in passion fruit commercial beverages (whole juices, reconstituted juices, tropical juices, and nectars) by their centesimal composition. Then, the energetic values were compared to the caloric values as described on the nutritional facts from the beverageslabels. Analyses of moisture, protein, lipids, ashes, and carbohydrates were done in 25 commercialbeverages samples. In order to calculate the energetic value of each sample, the following conversion factors were used: 4 kcal.g-1 for carbohydrates, 4 kcal.g-1 for proteins and 9 kcal.g-1 for lipids. To allow the comparison of the results, the energetic values printed on the labels were converted into kcal.100g-1 usingthe beverages density. Overall, the commercial beverages calculated energetic values were similar to the nutritional facts.

Se desarrolló un nuevo método para la valoración objetiva del color en las aceitunas, mediante el análisis de la intensidad de la reflexión de los colores primarios (rojo, verde y azul) que componen la luz blanca. Se trabajó con programas informáticos para el análisis de imágenes digitales color tipo BMP de 24 bits. Este método es rápido, objetivo, no destructivo y puede ser muy útil cuando se requiere una técnica eficiente para determinar el grado de madurez de las aceitunas o de otros alimentos.

Flor y fruto de vid [Vitis vinifera L.] : : micrografía aplicada a viticultura y enología

Un conocimiento apropiado de la anatomía de los diferentes tipos florales de la vid permite interpretar procesos de floración y fertilidad. Se ha observado durante cinco años las características de distintas variedades de vid en Mendoza (Argentina). Debido a las diferencias de variedades y viñedos, las observaciones se han tratado desde un punto de vista general. El estudio de las características anatómicas de la baya permite comprender fenómenos de maduración, estrés hídrico, deficiencias y productividad. En cuanto a los procedimientos tecnológicos, la observación de los componentes celulares del fruto: pared celular, polifenoles vacuolares, plástidos y ráfides de cristales de tartrato de calcio permite evaluar métodos enológicos, procesos de maceración y extracción de compuestos fenólicos y los tratamientos que deberían aplicarse para mejorar la calidad del vino.

Trips (Frankliniella brevicaulis Hood) de las erupciones del fruto de banano (Musa acuminata Colla) en la provincia de Formosa, Argentina

El banano en la provincia de Formosa (Argentina) es uno de los principales cultivos de renta y generador de mano de obra para el productor por lo que representa un importante lugar en lo social y económico. La sanidad de los cultivos es fundamental para lograr una mayor rentabilidad. Se han observado en los frutos daños atribuibles a trips. Los objetivos de este trabajo fueron identificar la/s especie/s de trips causal de las erupciones del fruto de banano en la provincia de Formosa, realizar una descripción detallada de su morfología y caracterizar y evaluar los daños producidos. La zona de trabajo correspondió al Área-Laguna Naineck en el Departamento Pilcomayo de la provincia de Formosa considerando un total de 1.103,74 ha pertenecientes a 233 productores. Para la determinación del estado sanitario de las plantaciones con respecto a la presencia del insecto se realizó un diseño de muestreo estadístico. Se recolectaron muestras del insecto y se identificaron con ayuda de claves. La única especie de trips encontrada fue Frankliniella brevicaulis. Los daños producidos por esta especie serían debidos a las heridas causadas por la oviposición, siendo éstas posibles fuentes de entrada para el hongo Colletotrichum musae. Se observaron daños en el 100% de los cachos de banana en todas las plantaciones evaluadas.
