The umbuzeiro is a native Brazilian semi-arid plant with great agroindustrial potential. The characterization of the fruit, as well as the development or improvement of technologies for value aggregation are fundamental for its conservation, dissemination and culinary expansion. The objective was to characterize physically and chemically fruits of umbu and to define the access with greater commercial potential. A completely randomized design was used, with 10 replications, in a total of 4 accessions of umbuzeiro. The fruits were selected prioritizing uniformity of fruit size and maturation stage. Fruit peel color was analyzed; diameter and length; mass of the fruit, the bark, the pulp and the seed; firmness of the fruit, soluble solids contents; pH; titratable acidity and solids/acidity ratio. The values of the pulp yield and the technological index were determined. Significance was verified for all variables, except for soluble solids and pH. The average value of the titratable acidity was 1.3 mg of citric acid 100 mL-1 of juice. The diameter of the fruits varied between 4.0 and 4.5 cm. Fruit mass varied from 33.00 to 43.62 g and access to EPAMIG-C06 was the heaviest. The accesses EPAMIG-C06 and EPAMIG-C18 presented the highest technological index. Based on the results, it was concluded that the accesses present potential to the pulp industry due to the size and characteristics of the fruits. The umbu accesses under study presented small variation for solubility and pH. For in natura consumption and/or processing, the access EPAMIG-C06 stands out due to attributes of commercial interest.

Abstract Passiflora cincinnata Mast. or Caatinga passion fruit is widely cultivated in the northeastern semi-arid regions of Goiás, Minas Gerais, and Bahia. The system of cultivation and field management of the Passiflora species affects the physicochemical quality of its fruits. In this study, we evaluated the chemical and physico-chemical characteristics of the fruits of 2 progenies (CPEF2220 and CBAF2334) of P. cincinnata species using the vertical and horizontal trellis system. Fruits were collected from the plants at their physiological maturation stage and tested for the fruit skin color and texture and the pH, total soluble solids, titratable acidity, pulp acidity ratio, and the contents of flavonoids, anthocyanins, and polyphenols in the seedless fruit pulp. The experimental design was completely randomized in a 2 x 2 factorial scheme (progenies x conduction system) performed in 3 replications using 4 plants in each. The analysis of variance and the means were compared using the Tukey’s test at 5% probability. The results revealed that the CBAF2334 fruits presented with greener pigments and greater flavonoids. The fruits were characterized by their green color with some yellowish nuances and a low color saturation in both the progenies. The conduction system was not found to affect the physical and physicochemical characteristics as well as the anthocyanin and polyphenol contents of the studied species. The fruits of plants cultivated on vertical trellis presented with 56.73% more flavonoid content than those cultivated on horizontal trellis.

Brazil has a range of fruit species, especially native ones, which play an important role in the life of local populations, but are still little studied, as is the case of bacuri (Platonia insignis Mart.). P. insignis is a fruit tree species native from Amazon region and has great economic potential, mainly due to its excellent organoleptic and nutritional characteristics. Therefore, there is a need for research that seeks the proper use of the species, as well as the selection of superior genotypes. Thus, the objective of this study was to characterize biometric and chemically fruits of eight selections of native P. insignis plants, from the municipalities of Presidente Juscelino and Santa Rita both located in Lower Munim region, state of Maranhão, Brazil. For the biometric characterization, 20 fruits, individually, were analyzed as to mass, longitudinal diameter, transverse diameter, conformation index, seed number, parthenocarpic segments number, pulp yield and bark mass, and for the chemical characterization, samples composed of six fruits were analyzed as to soluble solids (°Brix), total acidity (% citric acid), soluble solids/acidity ratio and pH. There was significant difference for all characteristics evaluated. High coefficients of variation were observed, indicating variability among the selections and possibility of taking advantage for the genetic improvement. The results allow to indicate the fruits analyzed, both for the industrial market and for the in natura consumption, especially for the ‘Domingão’ and ‘Mamão’ selections.

ABSTRACT Passiflora cincinnata Mast. (caatinga passion fruit) has acidic fruits with a peculiar flavor, green color when ripe and a low percentage of abscission making it difficult to identify the point of harvest. In order to verify the harvest period in two populations of P.cincinnata, flowers were marked in anthesis and after six periods the fruits were harvested. This study evaluated fruit mass, seeds and pulp mass, fruit dimensions and shape, percentage of water, color and texture of skin, volume, color and pulp yield, pH, soluble solids (SS), titratable acidity ratio, polyphenol content, flavonoids and anthocyanins. The assay was designed in a completely randomized design in a factorial arrangement (2x6), with two populations (CPEF2220 and CBAF2334) and six harvest periods (20, 40, 60, 80, 100 and 120 days after anthesis - DAA) with four repetitions. There was a reduction in thickness (43.1%) and percentage of water in the skin (9.3%), pH (40.1%), ratio, polyphenols content and pulp luminosity (brightness). There were increases in pulp mass and volume, seed mass, pulp mass yield in relation to the fruit (72%), and SS titratable acidity (44.9%) in CPEF2220 and equality between populations in fruit shape, pulp color, thickness and skin color (luminosity and ºhue), pH and polyphenols. Although after 100 DAA there were higher yields, between 60 and 80 DAA it was possible to identify characteristics of SS, pH, titratable acidity, mass, volume and pulp yield related to ripe fruits, allowing harvesting after 60 DAA.

The aim of this work was to carry out the chemical characterization and sensory analysis of strawberry fruits from cultivars Camp-dover, Dover, Camp-oso, Oso Grande, and Tudla-Milsei, grown in the southern region of Minas Gerais State. Soluble solids, titratable acidity, and the ratio between both characteristics were evaluated, in three replications. Sensory analysis was carried out by a panel of 34 non-trained assessors, recruited out of UNICENTRO students, professors, and employees. Assessors evaluated the samples for aroma and flavor using sorting-preference tests, with scores from 1 (less preferred) to 5 (most preferred). Appearance was assessed by means of a hedonic scale, from 1 (dislike very much) to 9 (like very much). Each assessor evaluated five samples of each cultivar for aroma and flavor. To evaluate external appearance, fruits were presented in polystyrene trays, covered with transparent film. Cultivars Camp-dover, Oso Grande, and Tudla-Milsei had the highest (p<0.05) contents of soluble solids (respectively 8.1, 7.8, and 7.6ºBrix); while for titratable acidity, the highest values were found in fruits of cultivars Tudla-Milsei, Oso Grande, and Dover (0.88, 0.80, and 0.60). For the soluble solids:titratable acidity ratio, cultivar Camp-dover (13.5) significantly exceeded all others. Fruits from cultivars Camp-dover and Oso Grande, for their good scores in aroma (3.70 and 2.80, respectively), flavor (3.82 and 3.52), and appearance (7.00 and 7.38) had the best acceptability. Considering the results all together, cultivars Camp-dover and Oso Grande stood out as promising options for strawberry growing, since their advantageous fruit characteristics are likely to favor commercialization.

<p align="center"><strong><em>ABSTRACT <br /></em></strong></p><p><em>Kristal guava is one of the popular guava cultivars nowadays. The guava has white flesh and not-perfectly-round shaped that resembles a crystal and seedless. However, during the growth period fruit undergoes several physical and chemical changes and susceptible to insect infestation and other damage, all of which can reduce their commercial value and thus cause significant yield and economic losses. The aim of this research was to evaluate the influence of different color and bagging materials on guava fruit development and quality. The research was conducted at farmer farm located in Cikarawang Dramaga, from November 2013 to April 2014. This research was arranged in a randomized block design with one factor, consisted of ten treatments and five replications. The treatments were red plastic, yellow plastic, green plastic, blue plastic, sponnet with red plastic, sponnet with yellow plastic, sponnet with green plastic, sponnet with blue plastic, sponnet with transparent plastic and unbagged. Fruit quality assesment was conducted in Postharvest Laboratory of Agronomy and Horticulture Department, Bogor Agricultural University and Center for Tropical Horticultural Studies. The result showed that bagging improved fruit size, external quality and accelerated fruit maturity. Sponnet with red plastic bagging resulted in the biggest fruit at harvest. Sponnet with yellow or with red plastic baggings were able to maintain fruit peel smoothness up to 85%. Sponnet and plastic bagging resulted in better external quality than bagging with plastic only. Bagging did not show any effect on internal fruit quality.</em></p><p><em> </em></p><p><em>Keywords: colored bag, guava cv.
