title: Effectiveness evaluation of alternative sanitizers in microbiological quality of strawberry (Fragaria ananassa Duch Var. Oso Grande) after artificial contamination by Escherichia coli

description: Abstract Washing and sanitization are considered particularly critical steps for the microbiological quality of fruits. At this stage, it is important to select the sanitizer which must have microbiological effectiveness. In the literature, there is a great interest on alternative sanitizers for microbiological quality control of food. This study aimed at verifying the effectiveness of sodium hypochlorite, ozone, ultrasound and citric acid as well as associations of ultrasound to the other techniques mentioned above in the microbiological quality control of strawberries cv. Oso Grande. In these trials, the fruits were initially subjected to artificial contamination by a strain of Escherichia coli ATCC 25922 and thereafter part of them was reserved as control samples; the remainder was submitted to different kinds of sanitization treatment. Then, some microbiological analyses of coliforms counts at 45 °C were performed with those present in the control samples and in the post-sanitization samples, through the enzymatic technique of chromogenic substrate. The three most efficient treatments for maintaining the microbiological quality of the fruit were 2% citric acid, 2% citric acid associated with ultrasound and ozone.

title: Characteristics of freeze-dried nanoencapsulated fish oil with whey protein concentrate and gum arabic as wall materials

description: Abstract Fish oil has many health effects, but due to its strong odor and rapid spoilage, its use in food formulations is limited. For these reasons, nanoencapsulation of fish oil can be important. The purpose of this study was to investigate the influence of whey protein concentrate (WPC) and gum arabic as wall materials on the characteristics of nanoencapsulated fish oil powder. Gum arabic and WPC were used in varying amounts for nanoencapsulation of fish oil. An oil-in-water emulsion with 6% fish oil and 20% aqueous solution of wall materials was prepared by sonication (24 kHz for 120 sec). The diameter of the emulsion droplets was measured by particle size analysis and they then were dried in a freeze-drier. The results showed that the type and concentration of wall material influenced the characteristics of the nanocapsules. The smallest emulsion droplet diameter (50 nm) and the highest encapsulation efficiency were found in the sample containing 100% gum arabic; however, the lowest amount of surface oil, pH and highest zeta potential and moisture content also were recorded for this sample. It can be concluded that gum arabic is more suitable for nanoencapsulation and could appropriately contain the volatile compounds within the capsules.

title: ENERGY PERFORMANCE IN DISC HARROWING OPERATION IN DIFFERENT GRADIENTS AND GAUGES

description: ABSTRACT The operational performance of the agricultural tractor can be increased by adjusting parameters such as tire inflation pressure, axle mass distribution and gauge opening, which is a very divergent factor in controlled-traffic production. The objective of the experiment was to measure the energy performance of a 93 kW agricultural tractor in intermediate grading operation in two slopes (flat and sloping) and three gauge configurations (closed, intermediate and open) in mobilized soil. Energy performance was determined from the following parameters: slip, engine speed, actual effective speed, hourly and specific fuel consumption; strength, power and performance on the drawbar. Turbo pressure and temperature monitoring was also performed at six different engine points. The experiment was conducted in double factorial arrangement (2 slopes and 3 gauges), with four replications, totaling 24 plots. Data were analyzed for normality and homoscedasticity of the residues, after ANOVA and when significant, the means test. Tilts and tire gauges did not differ statistically, so it can be concluded that depending on the operation do not interfere with operating performance.

title: Development of symbiotic yoghurt and biological evaluation (New Zealand White Rabbits) of its functional properties

description: Abstract Functional foods are those that bring benefits to human health beyond nutrition such as the prevention of cardiovascular diseases, allergies and intestinal problems. Among the functional foods highly consumed worldwide, yogurt is highlighted, especially in the probiotic and symbiotic versions. The aim of this study was to use the Jerusalem artichoke tuber flour ( Helianthus tuberosus L.) as a new prebiotic source for the development of functional yogurt. The identification and quantification of the fructans of the Jerusalem artichoke flour was performed and later yoghurt formulations were elaborated. These yogurts were submitted to analyses of centesimal composition, shelf life and sensorial evaluation. For the biological evaluation, a symbiotic yogurt formulation was chosen (the best accepted in sensorial evaluation) and included in the feed of New Zealand white rabbits, in the growth and final phase. The in vivo experiment had three distinct groups (control group, probiotic group and symbiotic group). At the end of 50 days of experiment, the animals were euthanized and submitted to the serological and cecal microbiota evaluation. Through this study, the prebiotic/bifidogenic capacity of Jerusalem artichoke flour was evidenced.

title: Number of carpels in the pollination efficiency of sour passion fruit

description: Abstract Passion fruit flowers usually have three carpels, but there are individuals with greater amount of carpels in their reproductive structures and little is known about the influence of this characteristic on this crop. Sour passion fruit (Passiflora edulis Sims, ‘BRS Sol do Cerrado’ cultivar) plants presenting flowers with three, four and five carpels were evaluated regarding the following characteristics: manual and natural pollination efficiency; frequency of different types of flowers in the orchard; and inclination of styles. Frequencies of flowers with three, four and five carpels were also evaluated in ‘BRS Sol do Cerrado’ genitors. There were no statistically significant differences in pollination efficiency among the different types of flowers, which presented averages above 90%, especially flowers with five carpels, with 100% efficiency. Flowers with three carpels are predominant in ‘BRS Sol do Cerrado’ cultivar, representing 88.93%, but flowers with four and five carpels did not show styles without inclination, whereas flowers with three carpels presented rate of 11.83%. Only the male genitor stands out for the rate of flowers with four and five carpels, being 37.33% and 7.33%, respectively. Thus, flowers with four and five carpels represent important characteristics for passion fruit breeding programs.

title: Give a fish or teach to fish? Empowerment as a practice of social innovation in a civil society organization

description: Abstract This article aims to analyze empowerment as a practice of social innovation in a civil society organization (CSO) working with vulnerable children and adolescents in the Northeast of Brazil. The study adopted an ethnometodological approach, using interviews with the organization’s staff, children and adolescents that participate or participated in the project, and their families. In addition, the study used participant observation, photos, videos, and document analysis. The results show that besides the individuals empowerment, the participants of the project became multipliers of the acquired knowledge, contributing to the development of other people in their networks. The social innovation practice analyzed has changed over time based on the action and demands of the children and adolescents involved, following their personal development process. Also, the practice is improved based on the CSO’s planning and work of mapping community needs. This article contributes to delineate an integrative theoretical conception, helping to investigate how the practice develops over time and is legitimized in the context, evidencing its founding elements and means of materialization.

title: Comparison of mathematical methods and measurements of traffic noise indices in pedestrian routes

description: Abstract In this study, we propose an analysis of the vehicular traffic noise indices and comparison between field measurements and prediction data obtained from mathematical models. The study area consists of two pedestrians routes of a medium-sized South American city. University students use these routes in displacements between their universities and residences. We monitored twenty-eight points along the two routes, performing three daytime measurements for each point. The calculated values were obtained from two mathematical predicted models: the English model CRTN (Calculation of Road Traffic Noise) and the French model NMPB-Routes (Nouvelle Methode de Prevision de Bruit). The measurements considered two noise descriptors: the A-weighted equivalent sound level (LAeq) and the noise pollution index (Lnp). The results show that the pedestrians are exposed to excessive levels of vehicle traffic noise along these routes. However, the analysis showed that the two mathematical models achieved good similarity and high performance in the prediction potential. The CRTN model has a better performance than NMPB, proving to be useful as an auxiliary tool in the monitoring of vehicle traffic noise. Finally, we used the CRTN (LAeq) predictions to generate the map of noise pollution indices.

title: Effect of biostimulant application and long-term storage on the nutritional value of carrot

description: ABSTRACT The nutritional value of carrot is determined by the content of total sugars and monosaccharides, carotenoids and vitamins, including vitamin C, in its roots. In 2009-2011, field experiments were carried out concerning the effect of biostimulating preparations applied during the carrot vegetation period on selected nutrients of its roots (total sugars, monosaccharides, carotenoids and vitamin C). Two biostimulants were foliarly applied in doses of 2 or 3 L ha-1 on various dates. Kelpak SL and Asahi SL: one, two or three applications; where, second and third applied at 2-week interval, additionally Kelpak SL: one application at 4-leaf phase, followed by additional application after 4 weeks. The field study was conducted in a randomized block design with four replications. The treatments of plant protection from diseases and pests complied with carrot requirements. The subject of the research was carrot of the Karotan cultivar. The content of selected components in carrot roots was determined directly after harvest and after six months of storage in the storage chamber with controlled temperature and relative air humidity. The foliar application of Kelpak SL in a single dose (2 L ha-1) at 4-leaf development phase resulted in the significant increase of total sugars, reducing sugars, total carotenoids and vitamin C. A six-month storage period resulted in a decrease of total sugars by 5% and ascorbic acid by 16.8% compared to nutritional values measured right after harvest.

title: Cachaça production from sugarcane infested by Diatrea saccharalis

description: Abstract Cachaça is a highly consumed Brazilian spirit, which still needs studies on its agroindustrial processing. We can highlight the effects of infestation of pest insects in the sugarcane, and the chemical-physically characteristics of the drink. So, the aim of the study was to evaluate the consequences of the infestation of the sugarcane borer (Diatrea saccharalis) on the quality of the cachaça. The borer infestation results in less stalks productivity per hectare, and higher rates of acidity and phenol in juice and must. However, the borer did not affect the Brix, Purity, Total Reducing Sugars and pH of raw material. The cellular viability of infested stalks is less than of not infested stalks. The chemical-physical characteristics of the cachaça for both treatments meet the Brazilian legislation. However, the acetic acid is higher for infested stalks.
