Abstract Uvaia (Eugenia pyriformis Cambess) is a fruit tree native to the Atlantic Forest and that features peculiar aroma and flavor. Although this fruit is highly popular locally, its commercial farming is virtually nonexistent. In addition, limited studies on this fruit have been conducted. Therefore, the present study aimed to investigate the physical, chemical, and functional characteristics of two uvaia fruit populations grown in Salesópolis, SP, Brazil, in order to determine their potential for being consumed both in natura and processed. Uvaia fruits were evaluated as for skin color, whole fruit weight, longitudinal and transversal diameters, seed percentage, pulp yield, pulp firmness, pH, total soluble solids (TSS), total titratable acidity (TTA), TSS/TTA ratio, total soluble sugars, soluble and total pectins, total carotenoids, yellow flavonoids, total phenolic compounds, ascorbic acid, and in vitro antioxidant capacity (DPPH and ORAC assays). The total mineral content was also determined. Comparison among the two populations revealed that uvaia fruits showed significantly different firmness values, large fruits showing suitable characteristics for the fresh fruit market. However, small fruits were sweeter and richer in antioxidants, allowing the consumption of both natural and processed fruits. Thus, this native fruit denotes an important source of nutrients and bioactive compounds, especially iron.

Physical And Chemical

The fruit physical and chemical characteristics can vary during the maturation period and this variation depends, among other factors, on the weather conditions during fruit development. This study aimed to evaluate the changes in physical and chemical characteristics of eight peach cultivars during two seasons. The cultivars Campinas 1, Coral, Maciel, Marli, Premier, Regis, Rei da Conserva and Tropic Beauty were planted on Okinawa rootstock at the experimental orchard of the Federal University of Viçosa (UFV), Viçosa-MG, Brazil, in 2008 and the following characteristics were evaluated: fruit weight, skin color, firmness, soluble solids, titratable acidity, ascorbic acid and total carotenoids. The experiment was conducted during 2011 and 2012 growing seasons in a completely randomized design with eight treatments (cultivars), three repetitions and 10 fruits per plot. There were differences between the variables for the two seasons, with the largest variations observed for firmness, ascorbic acid and total carotenoids. Cultivars Maciel and Marli produced fruit with higher mass, Tropic Beauty with greater firmness and Rei da Conserva, Coral and Marli with higher soluble solids contents. The cultivar Rei da Conserva presented higher values for most of the evaluated variables in both seasons. The yellow color, evaluated by the hue angle, is associated with total carotenoids content in peaches.

Microbiological Properties

The impact of ozone concentration and ozonisation time on the selected chemical, physical and microbiological properties of Rapanui tomatoes was investigated. Tomatoes were exposed to gaseous ozone at concentrations of 0.9 and 2.5 mg L−1 (c1, c2) for 30 and 120 min (t1, t2), and stored for up to 15 days at a temperature of 12 ± 1 °C. The following parameters were evaluated: titratable acidity, total soluble solids, total phenolic and flavonoid contents, lycopene, total carotenoids, vitamin C, total antioxidant activity, colour L* a* b* and firmness. Ozonated fruit had higher levels of total soluble solids and higher levels of titratable acidity during and after storage. Exposure of tomatoes to a cooling atmosphere, applying recommended ozonisation process parameters, efficiently inactivated microorganisms that are present on the surface and reduced fruit weight loss, while retaining their firmness and stable colour.

The green bean is an important crop worldwide, because it is rich in protein, dietary fiber, vitamins, and minerals, as well as bioactive compounds that provide it with important functional properties; however, the composition of many landraces is still unknown. The purpose of this project was to characterize Phaselus vulgaris and coccineus L. landrace green beans on pH, titratable acidity, total soluble solids, total sugars, color parameters, total phenols, monomeric anthocyanins, and in vitro antioxidant activity (DPPH and FRAP). Regarding the content of total sugars, differences were registered between both species, as opposed to results observed in total soluble solids. Color parameters showed higher reddish tones for P. vulgaris landraces, though P. coccineus had a higher total phenolic content, especially the reddish landraces, which correlated directly to a higher antioxidant activity by DPPH and FRAP. In the protein content, the species P. vulgaris registered the highest content. These results could contribute to a greater use and even promote the genetic improvement of the outstanding pods that serve as one of the main food products in rural regions for higher benefits.

Prevalence of heavy soil is a major problem for fruit cultivation under Punjab conditions consequently leading to deficiency of several micro-nutrients including zinc (Zn), iron (Fe), and manganese (Mn) which adversely affects the growth and productivity. In this view, a study was planned to investigate the effect of foliar applications of zinc sulphate (ZnSO4), iron sulphate (FeSO4), and manganese sulphate (MnSO4) on vegetative growth, reproductive growth and fruit quality of papaya cv. Red lady. Plants sprayed with ZnSO4 (0.4 %) exhibited significantly highest plant height, plant girth, number of leaves, petiole length; initiated an earliest flowering and fruiting; and improved fruit quality viz., fruit weight, fruit length, titratable acidity, soluble solids concentrations, ascorbic acid content, total phenols content, and total carotenoids content as compared with the control and all other treatments. In conclusion, foliar application ZnSO4 (0.4 %) significantly improved plant growth and fruit quality in papaya cv. Red lady.

Tomato Fruit Ripening

Tomato (Lycopersicon esculentum Mill.) fruits, cv. Santa Clara, were harvested at the breaker stage from commercial fields in Brazlândia, Brazil, to investigate the ability of 1-methylcyclopropene (1-MCP) to retard tomato fruit ripening. Fruit without external blemishes were graded for size (diameter = 80±5 mm) and mass (m = 130±10 g), placed inside hermetically sealed boxes, and 1-MCP was applied for 12 hours (T = 22±1°C; RH = 80-85%) at four different concentrations: 0 (control), 250, 500 and 1000 mL.L-1. Fruits were held at ambient conditions (T = 23±2°C; RH 80-85%) for 2 days and then stored inside a cold room (T = 20±1°C; RH = 85-95%). Every 3 days, during a 15-day period, fruits were analyzed for firmness, total soluble solids, titratable acidity, external color, and total carotenoids. Firmness of fruit treated with 1000 mL.L-1 was about 88% higher than control fruits after 17 days. The a*/b* ratio, an indicator of skin color, for fruit treated with 1000 mL.L-1 of 1-MCP was 38% lower than control fruits at the end of the storage period. Treatments with higher concentrations of 1-MCP delayed total carotenoids synthesis and color development. Control fruits stored for 17 days had about 190% more total carotenoids than fruits treated with 1000 mL.L-1 of 1-MCP. Postharvest application of 1-MCP was an efficient method to delay tomato fruit ripening. As 1-MCP concentration increased, ripening was further delayed. Tomatoes treated with 250, 500, and 1000 mL.L-1 of 1-MCP were delayed by 8 to 11, 11 to 13 and 15 to 17 days, respectively.

Abstract Pereskia aculeata Miller is a native cactaceae found from the Northeast to the South of Brazil. This plant is recognized by the high nutritional value of their leaves, which are the most used in cooking and folk medicine. However, studies on the chemical characteristics and antioxidant capacity of the ora-pro-nobis fruits are scarce. Therefore, the aim of this study was to determine the best harvest point of the ora-pro-nobis fruits to optimize the content of bioactive compounds and their antioxidant capacity. The fruits were manually harvested, defined by their peel colors in three maturity stages: unripe (green), intermediate (yellowish green), and ripe (yellow) stages. The following attributes were evaluated: soluble solids (SS), titratable acidity (TA), SS/TA ratio, pH, and content of bioactive compounds, such as total chlorophylls, carotenoids, yellow flavonoids, total phenolic compounds, and antioxidant capacity. There was a decrease in the content of chlorophyll followed by an increase in the of total carotenoids and yellow flavonoids, due to the maturity stage. For the total phenolic compounds, it was not observed significant difference between the stages. The antioxidant capacity was quantified by the ORAC method in lyophilized pulp in the unripe (1.95 mmol 100 g-1 trolox) and ripe (3.85 mmol 100 g-1 trolox) stages. The lowest contents were observed in the intermediate (0.80 mmol 100 g-1 trolox in lyophilized pulp) stage. The maturity stage significantly influenced the bioactive compounds of ora-pro-nobis, which presented higher values of total carotenoids, yellow flavonoids, and antioxidant capacity in ripe fruits.

Abstract This study aimed to evaluate the flowering period and the physicochemical characteristics of peaches, aiming to find those most promising for the diversification of the peach crop in the Metropolitan Region of Curitiba, Paraná State. We evaluated 8 selections and three cultivars in Porto Amazonas and 10 cultivars in Araucaria for flowering period, fruit set, diameter and height of fruit, average fruit weight, the skin color, soluble solids (SS), titratable acidity (TA), ratio SS/ TA, hydrogen potential (pH). The flowering period occurred between late June and late September ranging from 16 to 25 days. The fruit set rate was greater than 50% for ‘Cascata 1513’, ‘Cascata 1429’, ‘Cascata 1577’, ‘Cascata 1743’ and for all cultivars in Araucaria. There were significant differences for the other variables assessed. It was concluded that in Araucária, ‘Charme’ and ‘Chimarrita’ are good planting options, have the same duration of the cycle (111 days), being ‘Charme’ a little later. Besides these, ‘Douradão’ and ‘Rubimel’ have good fruit size, moderate acidity and best SS/TA ratio, being earlier than the previous ones. ‘PS 25399’ is the earliest and showed reddish epidermis and great consumer interest. In Porto Amazonas, selections and cultivars tested produced little fruit of small size, being required more studies to be recommended in these area.

The rootstock influences the agronomic performance of fruit plants. In Prunus persica (peach), particularly those varieties produced in Brazil, this relationship is not well understood. We, therefore, set out to evaluate the performance of the peach cultivar Maciel with eight rootstocks, Aldrighi, Capdeboscq, Flordaguard, Nemaguard, Okinawa, Umezeiro, Tsukuba, and Seleção Viamão, planted in 2006 and evaluated in the 2014/2015 and 2015/2016 seasons. Phenology of flowering, trunk diameter, canopy volume, fruit number, and yield were evaluated in the field. For the fruit, we evaluated the mass, diameter, color, flesh firmness, soluble solids concentration, titratable acidity, concentration of total phenolic compounds, carotenoids, and antioxidant activity. Plants from the Aldrighi and Nemaguard rootstocks flowered earlier than plants from the other rootstocks in 2014, and in 2015, flowering was variable in all rootstocks. The cultivar Maciel on Umezeiro had low vigor, trunk diameter, and canopy volume. On Aldrighi, Capdeboscq, Flordaguard, Nemaguard, and Tsukuba this cultivar showed good production rates. The fruit color, flesh firmness, concentration of soluble solids, total phenolics, antioxidant activity, and total carotenoids were influenced by rootstock and harvest.

This study aimed to estimate genetic parameters and identify promising clones of Spondias mombin in ungrafted commercial crop by stratified mass selection, based on the average of two harvests, using mixed models. The base population growing on a private farm in Teresina/PI comprised 82 plants, which were evaluated in the growing seasons 2008 and 2009. Total titratable acidity (TTA), total soluble solids (Brix), Brix/TTA, fruit weight (FW), seed weight (SW), pulp yield (PuY), and processing yield (PrY) were measured. Significant genetic variation among plants was detected for all traits. The coefficients of repeatability were 0.97 (TTA), 0.39 (Brix), 0.86 (Brix/TTA), 0.84 (FW), 0.82 (SW), 0.35 (PuY), and 0.39 (PrY). The chemical were generally not correlated with the physical fruit traits. Ranking by predicted phenotypic values associated with PrY and Brix/TTA identified nine promising plants (PrY>6.9% and Brix/TTA>10).

Belonging to the family Myrtaceae, ‘sete capotes’ is a plant native to the Atlantic Forest biome. It produces yellow-green fruits between February and May. Although used for consumption by local populations, studies of the fruit are rare. The present work aimed at characterize the fruit in terms of physicochemical properties. We quantified mass, volume, moisture, pulp yield, pH, titratable acidity, soluble solids/titratable acidity, proteins, lipids, total sugars, reducing sugars, ash, macronutrients, micronutrients, pectin, vitamin C and phenolic compounds. Compared with commercial fruits and other native fruit trees, sete capotes is unusual for its pulp yield, vitamin C levels, total phenolic compound content, protein levels, calcium content, potassium levels and iron content. Through the results it is verified of the fruit as a functional food, mainly because of its nutritive content and because of its bioactive compounds. Our data emphasize the importance of study of the constituents of native flora.
