title: Sensory evaluation and antioxidant capacity as quality parameters in the development of a banana, strawberry and juçara smoothie

description: Abstract In the present study a banana, strawberry and juçara smoothie was developed using an experimental mixture design. The juçara proportion was kept constant while the banana:strawberry ratio varied and the main responses were the sensory acceptability and the antioxidant capacity. From five formulations, only the one with the highest percentage of strawberry was rejected, most likely due to its lower sugar content and higher acidity. In general, panelists chose the sweeter formulations, which were those with a higher percentage of banana. Relating to the consistency, the best formulation was the one containing the same proportion of strawberry and banana pulp, which provided a better flow to the product. Additionally, this sample showed intermediate values of phenolic compounds and antioxidant capacity, as well as desirable physicochemical characteristics. In spite of being possible to obtain four formulations with good sensory acceptance, the one with equal amounts of banana and strawberry pulp is highlighted due to its antioxidant capacity and sensory characteristics, statistically corroborated by the desirability function.

title: Calcium anacardate as growth promoter for piglets at the nursery phase

description: Abstract: The objective of this work was to evaluate the effects of the dietary inclusion of calcium anacardate on the performance, diarrhea incidence, blood parameters, intestinal morphometry, and pH of gastrointestinal contents in piglets from 21 to 42 days of age. Sixty weaned Topigs piglets, with initial weight of 6.049±0.311 kg, were distributed in the following treatments: diet with or without antibiotic growth promoter (zinc bacitracin) and diets supplemented with increasing levels of calcium anacardate (0.4, 0.8, and 1.2%), with six replicates and two animals per experimental unit. No differences in performance (21 to 42 days of age), blood parameters, and villus height:crypt depth ratio were found between piglets fed diets containing calcium anacardate or antibiotic growth promoter. The replacement of the antibiotic growth promoter zinc bacitracin by calcium anacardate results in similar performance in piglets from 21 to 42 days of age, without changes in blood parameters and in the villus height:crypt depth ratio. The dietary inclusion of calcium anacardate does not decrease diarrhea incidence compared with the antibiotic zinc bacitracin.

title: Metal trace elements in mussels in Urubuqueçaba Island, Santos Bay, Brazil

description: Abstract: The objective of this work was to verify the existence of bioaccumulation in mussels of the species Perna perna, by determining the concentration of metal trace elements, in Urubuqueçaba Island, Santos Bay, Santos, SP, Brazil. Mussels were collected in natural banks and rocky shores, and sampling took place from April 2010 to June 2011. The concentration of the trace metal elements - aluminum, cadmium, cromium, copper, iron, manganese, nickel, lead, and zinc - was determined according to mussel sex, length, and seasonality classes, in a flame atomic absorption spectrometer. Statistical analyses were applied to the results with the use of the software PAST, with parametric and nonparametric approaches, at 5% probability. In the summer, mussels show the highest concentrations of cadmium, copper, lead, and zinc. Females of P. perna concentrate more copper; for the other elements, there are no significant differences between sexes. The length classes with the highest concentrations are 3.5-5.5 cm for Al and Fe, and 6.5-8.5 cm for Cr.

title: Ultrasonic-extraction of phenolic compounds from Phyllanthus urinaria: optimization model and antioxidant activity

description: Abstract Ultrasonic-assisted extraction technique was used to extract phenolic compounds from Phyllanthus urinaria and response surface methodology was used to optimize the extraction parameters including ultrasonic time (X1), ethanol concentration (X2) and solid-liquid ratio (X3). A mathematical model of the tree parameters for the high extraction yield (Y) was established. Antioxidant activity of the phenolic compounds was investigated by DPPH free radicals, ABTS free radicals, hydroxyl free radicals and reducing power assay with vitamin C as a control. The results showed that the independent variables (X1, X2 and X3) and the interaction terms (X1X3 and X2X3) had a significant effect on the extraction yield. The effect of the variables on the extraction yield was in the order of X3, X1 and X2. The optimal extraction process was X1 of 34 min, X2 of 46.5% and X3 of 1:63 g/mL, and the extraction yield was 9.59%, which was well matched with the predicted value. The antioxidant activity assay indicated that the phenolic compounds from Phyllanthus urinaria have a good antioxidant activity.

title: Influence of temperature and packaging type on quality parameters and antimicrobial properties during Yateí honey storage

description: Abstract Tetragonisca fiebrigi, is a bee of the subfamily Meliponidae traditionally known as Yateí. Its honey differs from the honey produced by Apis mellifera because it is less viscous, more acidic, has sweetness and particular aromas. It is important to know the behavior of yatei honey in different storage conditions, in order to preserve the characteristics of the honey and ensure the product as harmless. The objective was to determine the influence of temperature, packaging type and storage time of Yateí honey on antimicrobial properties, microbial (Total Mesophilic Aerobic and Mold and Yeast Count) and physicochemical parameters (pH, hydroxymethylfurfural (HMF), acidity, moisture content and diastase), with methodology of national and international standards. The antimicrobial effect was variable against strains of the genus Staphylococcus aureus. The most significant microbiological quality levels were Mold and Yeast counts (&gt; 102 CFU / g). The physicochemical parameters with the most significant values were acidity (to: 42.5 meq acid/kg honey), moisture content (to: 26%) and HMF (to: 3.8mg/kg honey). Storage at refrigeration temperature maintained standard values close to Apis mellifera honey during 180 days; whereas at room temperature it was better to maintain antimicrobial power. No significant difference was found between plastic storage containers vs. glass.

title: Control of mycotoxigenic fungi with microcapsules of essential oils encapsulated in chitosan

description: Abstract Aspergillus and Fusarium are the fungi genera most frequently isolated from cereal grains and other commodities. They are capable of producing mycotoxins, which can affect the human and animal health. Synthetic fungicides have been used to control these fungi, nevertheless, they have acquired resistance and other alternatives are necessary since they now need higher amounts. Therefore, the aim of this study was to evaluate the efficacy of cinnamon, clove and thyme essential oils (EOs) alone and encapsulated in chitosan on the radial growth, spore germination and mycotoxin production by Fusarium verticillioides and Aspergillus parasiticus. The composition of the EOs was determined by gas chromatography mass spectrometry (GC-MS). EOs inhibited radial growth and spore germination of both fungal species better than when they were encapsulated, plus, they reduced mycotoxin production. The major components were eugenol in cinnamon and clove EO (70 and 63%, respectively) and 2-methyl-5-(1-methyethyl)-phenol (46.2%) in thyme EO. The microparticles with clove and thyme EO showed good surface charges, higher than +30 mV and their average size for the three types of microparticles was about 750 nm. Our findings suggest that EOs both alone and encapsulated in chitosan have a fungistatic effect on Fusarium verticillioides and Aspergillus parasiticus.

title: Reduzindo a Incerteza no Mercado de Seguros: Uma Abordagem via Informações de Sensoriamento Remoto e Atuária

description: Any insurance contract includes two key parameters: the premium rate and the indemnity. The methodology for calculating the premium rate is fundamental to avoid information asymmetry problems while methods to monitoring the insured object can be useful to measure and control losses. Usually uncertainties in relation to the cash ﬂow of companies in a contingent market are high. This study proposes that this uncertainty can be reduced through alternative pricing methods based on Bayesian hierarchical models and geotechnology. The methodology allows for a better understanding of the temporal and spatial dynamic of the cash ﬂow of an economic agent in the crop insurance market in Brazil at municipality level. The results show that fair premium rates can be precisely estimated using the pricing methodology and that geotechnology brings about significant improvements in quantifying crop losses.

title: Development of a Body Image Scale for Brazilian women

description: Abstract Body image is an important parameter of body satisfaction and needs to be evaluated with instruments developed and validated for a specific population. The aim of this study was to develop and validate a scale to assess body image in Brazilian women. A scale consisting of 11 silhouettes was prepared. Content validation was performed by seven experts from different health areas. To assess repeatability (two consecutive assessments) and reproducibility (reassessment after one week), an intentional sample stratified into four groups according to the characterization of Brazilian women regarding nutritional status was selected. Participants were 125 women aged 18-55 years and body mass index (BMI) between 18.5 and 38.6 kg/m2. The Kappa coefficient (k) was used to assess repeatability and reproducibility, considering the isolated responses of the current body, ideal body and the difference between them, assumed as satisfactory when k≥0.6. For all trials, α=0.05. During the content validation phase, the instrument developed was changed following the evaluators’ suggestions and it was considered very suitable by six of seven evaluators. The Kappa coefficient was good in isolated issues and in the difference between them in both repeatability and reproducibility. The Body Image Scale was considered a valid content, with good repeatability and reproducibility. Considering the instrument as low cost and of rapid implementation/evaluation, it may be used to evaluate the body image of Brazilian women with BMI between 18.5 and 38.6 kg/m2, in different contexts.

title: Interference of germination time on chemical composition and antioxidant capacity of white sesame (Sesamum Indicum)

description: Abstract The consumption of white sesame has become a healthy option for those who are concerned about health and wish to reduce oxidative stress. The germination has been used an effective method to increase the nutrients availability and thus provide a better nutritional quality of these seeds. Due to the lack of researches about sesame germination the objective of this study was to evaluate the different times of germination on the chemical composition (moisture, fat, protein and ashes), the antioxidant capacity and the phenolic compounds of white sesame. The germination occurred inside a greenhouse with controlled temperature at 30 °C and the variables were analyzed in the times 0, 24, 36 and 48 hours of germination. The process increased the levels of moisture and reduced the levels of fat, protein and ashes. On the other hand, it also increased the antioxidant capacity by two methods and raised the quantity of total phenolic compounds. Based in the present study and in others similar works, it is possible to affirm that the germination process increase the white sesames’ antioxidant capacity, however further studies are needed to evaluate a better environmental condition of germination and others factors that may affect the composition.
