Exotic Fruits

The pitahaya or dragon fruit is one of the most representative exotic fruits that Colombia has, with an important, growing international market, but the cultivation and postharvest of this fruit lack sufficient technological support to be more competitive. Therefore, alternatives that provide good-quality products that meet market requirements are very important. Therefore, the objective of this research was to determine the effect of a ripening retardant and ethylene application on the conservation and quality of pitahaya fruits and the possible changes during ripening associated with ethylene, for which a completely randomized design with three treatments was used, corresponding to the application of ethylene (ethephon, 3 mL L-1), 1-methylcyclopropene (1-MCP, 600 mg L-1) and a control, with four replications, for a total of 12 experimental units. The fruits were stored at 18°C with 75% relative humidity. The 1-MCP application significantly decreased the loss of firmness, total soluble solids, loss of fresh mass and respiratory rate. Fruits from the control and ethylene treatment tended toward a climateric respiratory behavior. The total carotenoid content of the fruits was significantly higher in the ethylene application and the control treatment, which was consistent with the color change of the fruits. It can be concluded that the 1-MCP application reduced the ethylene action, slowing the ripening of the dragon fruits.

Cape Gooseberry

Cape gooseberry ( Physalis peruviana L.) fruits are highly perishable berries that exhibit a climacteric respiratory behavior. The objective of this study was to evaluate the effect of ethylene and the ethylene action inhibitor 1-methylcyclopropene on the postharvest behavior of cape gooseberry fruits (ecotype Colombia). Fruits were treated with ethylene, in an ethephon application (1000 µL L−1), and pretreated with 1-methylcyclopropene (1 µL L−1), 1-methylcyclopropene+ethylene, and results compared with a control without application. Subsequently, the fruits were maintained at room temperature (20 ℃, 75% RH) for up to 11 days. The pretreatment of the cape gooseberry fruits with 1-methylcyclopropene delayed most of the ripening-associated parameters, with a reduction in the respiration rate and ethylene production, skin color development, total soluble solids, total carotenoid content, loss of firmness, loss of total titratable acidity and emission of volatile compounds such as ethyl octanoate, ethyl butanoate, ethyl decanoate, and hexyl decanoate. Conversely, application of ethephon accelerated most of these physiological changes and also overcame most of the effects prevented by the ethylene action inhibitor. Altogether, the results supported the idea of a climacteric-like behavior for cape gooseberry fruits and pointing out that the pretreatment with 1-methylcyclopropene may be a promising and efficient postharvest treatment to delay maturity and extend the postharvest period.

In this study, popularly consumed traditional chayote leaves and locally produced pineapple fruit were used to develop a fermented smoothie using lactic acid bacteria (LAB) strains: Lactobacillus plantarum (L75), Weissella cibaria (W64), and their combination (LW64 + 75). The physicochemical parameters [pH, total soluble solids (TSS), and color], total phenols, and carotenoid contents of the smoothies fermented for 48 h and stored for 7 days at 4°C were compared with the unfermented (control) smoothies. Results indicated that LAB fermentation reduced the pH from 3.56 to 2.50 after 48 h (day 2) compared with the non-fermented smoothie at day 2 (pH 3.37). LAB strain L75 significantly reduced the TSS content of the smoothies to 13.06°Bx after 2 days of fermentation. Smoothies fermented by L75 showed overall acceptability after 7 days of storage compared with the non-fermented puree on day 0. The LW64 + 75 significantly reduced the color change (ΔE), which was similar to the control. L75 increased the phenolic content, and W64 enhanced the total carotenoid content of the smoothies after 2 days of fermentation compared with other treatments. The use of an in vitro model simulating gastrointestinal (GI) digestion showed that fermentation with L75 improved the total phenol recovery by 65.96% during the intestinal phase compared with the control. The dialysis phase mimicked an epithelial barrier, and 53.58% of the recovered free soluble are bioavailable from the L75 fermented smoothies compared with the control. The antioxidant capacity of dialyzable fraction of the L75 fermented smoothie was significantly higher than that of the control and smoothies fermented with W64 or LW64 + 75.

The effects of 1-methylcyclopropene (1-MCP), an inhibitor of ethylene action, on the ripening and quality of Fantasia nectarines were examined. Fruit were harvested from two commercial orchards and subsequently exposed to 1 μL L-1 of 1-MCP for 24 h at 0°C. Following treatment, fruit were held at 0°C for 0, 2, or 4 wk, and then assessed for quality during a ripening period at 23°C. 1-MCP treatment improved postharvest firmness retention in nectarines after 0 and 2 wk at 0°C plus 4 days at 23°C. Soluble solids concentration (SSC) was lower in nectarines treated with 1 MCP and held for 0 or 4 wk at 0°C, compared with similar non-treated fruit. The peel ground color change from green to yellow was also delayed by 1-MCP. Nectarines treated with 1-MCP exhibited less CO2 and hydrophobic volatile production during 14 days at 23°C, compared with non-treated fruit. The overall inhibition of fruit ripening by 1-MCP appears transitory in Fantasia nectarines. Chilling injury was observed after 4 wk of storage at 0°C and 1-MCP-treated fruit had less visual chilling-related injury but greater chilling-induced flesh hardening. Further research is needed to determine the effects of 1-MCP on different chilling injury symptoms in nectarines. Key words: 1-MCP, fruit quality, ripening, storage, shelf-life, Prunus persica

This experiment was conducted to determine the effects of deficit irrigation and growing season on fruit quality, carotenoid content and yield of red-, orange-, and yellow-fleshed diploid and triploid watermelon. Irrigation rates were 1.0 evapotranspiration (ET) and 0.5 ET. Diploid cultivars were Summer Flavor 710 (red), Tendersweet (orange), and Summer Gold (yellow). Triploid cultivars were Summer Sweet 5244 (red), Sunshine (orange), and Amarillo (yellow). Four-week old containerized transplants were planted in the field at TAES-Uvalde on 27 Mar. and 21 May 2003. Deficit irrigation imposed after plants were fully established reduced the individual fruit weight and size in the early planting. Soluble solids content (SSC) and firmness was not affected by irrigation rate in both plantings. SSC varied across cultivars and increased with maturity, particularly for the triploid cultivar Amarillo. In general, triploids were firmer than diploid cultivars. Total carotenoid content was not affected by irrigation during early planting. Diploid and triploid red-fleshed watermelon cultivars had significantly higher carotenoid content than orange- and yellow-fleshed cultivars. The major carotenoid was lycopene (more than 65%), followed by prolycopene (20%) and B-carotene (7%).

The study of ionizing irradiation with Cobalt 60 (60Co), in this experiment, aimed to evaluate its influence on postharvest physical parameters for atemoia cv. ‘Thompson’, which are related to the fruit ripening process. The irradiation was carried out at the Radiation Technology Center -CTR IPEN / CNEN -SP, located in the university city USP (University of São Paulo) in the compact multi-purpose radiator where gamma rays are used. Atemias were irradiated with the following doses of cobalt 60 (60Co): T0 = No irradiation (control), T1 = 0.2kGy, T2 = 0.4kGy, T3 = 0.6kGy, T4 = 0.8kGy, T5 = 1,0kGy and T6 = 1,2kGy and then packed in expanded polystyrene trays (2 fruits / tray) and sealed with 0.020mm polyvinyl chloride films; exception made to the control treatment which did not receive irradiation; for each analysis parameter there were three repetitions with two fruits per repetition. The fruits under study were stored in a cold chamber at 15 ± 0.2ºC and 90 ± 2% RH. In all irradiation doses, the following analyzes were carried out: loss of fresh mass, soluble solids (SS), titratable acidity (AT), pH, ascorbic acid (AA), reducing sugars, respiratory rate. The analyzes were analyzed every three days (0,3,6,9,12,15 and 18) days of storage. The experiment was conducted in a completely randomized design (D.I.C.), in a factorial scheme (treatment x storage), composed of seven doses of gamma irradiation and seven storage times. The results were subjected to analysis of variance and the means compared by Tukey's test at the level of 5% probability and regression was performed for the analyzes in the storage period. This experiment can conclude that the doses of 1.0kGy and 1.2kGy demonstrate greater control of breathing, in atemoia, until the 9th day; three days more than the control treatment, the other parameters analyzed did not show any interference in the increase in postharvest life of the atemous cv ‘Thompson’.

Traits related to fruit yield and physical and chemical fruit quality are being evaluated by Embrapa pumpkin breeding program. Path and Pearson's correlation analysis are necessary to allow the knowledge of the relation between the variables of interest for this program. The objective of the present study was to determine the genetic correlations between yield- and sensorial and nutritional quality attributes-associated variables in pumpkin progenies to support the selection process. Twelve genotypes were evaluated for 10 yield-related traits, and 8 sensory and nutritional quality traits of fruit, including the commercial cultivar Jacarezinho. A path analysis considered the fruit weight (FrW) was as basic variable and the others as explanatory. The FrW had 98% of its total variation available in a function of the explanatory variables. The highest variations were observed in the fruit-shape related traits. In addition, the variables internal median cavity diameter (IDmed), equatorial pulp thickness (EPT), apical pulp thickness (APT), and smallest fruit diameter (Dsm) are indicated for a direct selection of progenies targeting a higher FrW. The correlation analysis highlighted that color-related variables have the possibility of indirect selection aiming to increase total carotenoid content (TCC) and β-carotene content (β-car). The evaluated progenies showed notable soluble solids content (SSC), TCC and β-car contents compared to the commercial cultivar. Furthermore, the contribution of β-car to TCC is at least 50% higher in these progenies than in 'Jacarezinho' pumpkin.

Significant differences (p ? 0.05) were observed among the cherry tomato lines for the principal antioxidants, viz. total carotenoids, lycopene and vitamin-C. Vitamin-C content ranged from 17.62 - 46.16 mg/100 g, the total carotenoid content ranged from 3.86 - 6.66 mg/100 g and lycopene content ranged from 2.83 - 5.26 mg/100 g on fresh weight basis. The total phenolics, another important class of antioxidants, also differed significantly amongst the cherry tomato line (12.41-31.17 mg gallic acid equivalent/100 g). Significant variation (p ? 0.05) was also observed for pH and titrable acidity. The pH varied from 4.15 - 4.52 and anhydrous citric acid ranged from 0.050 up to 0.323%. The total soluble solids were 3.41 - 5.16%. The maximum vitamin-C content was recorded in VRCT-6 (46.16 mg/100 g) closely followed by VRCT-7 (45.51 mg/100 g) and VRCT-15 (44.71 mg/100 g), whereas maximum total carotenoid content were recorded in VRCT-16 (6.66 mg/100 g) followed by VRCT-7 (6.48 mg/100 g) and VRCT-1(6.36 mg/100 g), respectively. On the other hand, maximum lycopene content was estimated in VRCT-16 (5.26 mg/100 g) followed by VRCT-3 (5.23 mg/100 g) and VRCT-14 (4.73 mg/100 g). Maximum acidity and total water soluble solids were recorded in VRCT-9 (0.323%) and VRCT-7 (5.16%), respectively. DOI: http://dx.doi.org/10.3329/bjb.v43i3.21591 Bangladesh J.

Abstract: The objective of this work was to evaluate the physicochemical composition, the bioactive compounds, and the total antioxidant activity of the fruit pulps of abiu (Pouteria caimito), achachairu (Garcinia humilis), araza (Eugenia stipitata), bilimbi (Averrhoa bilimbi), and yellow mangosteen (Garcinia xanthochymus) from the Brazilian Amazon biome. Total soluble solid content, total and reducing sugar contents, titratable acidity contents, pH, ascorbic acid content, moisture, protein, lipid, ash, and caloric value were determined. The contents of total anthocyanins, yellow flavonoids, and total carotenoids, besides total phenolic compounds and antioxidant activity, were also evaluated. The abiu pulp showed the highest contents of ash, total sugars, reducing sugars, total soluble solids, calorie value, and pH, among the analyzed fruits. The achachairu pulp showed the highest content of total phenolic compounds, with significant antioxidant activity, while the araza pulp had the highest total carotenoid content, and the yellow mangosteen, the highest yellow flavonoid content. The positive correlation between antioxidant activity and total phenolic compounds suggests that these compounds are the most important for determining antioxidant activity in the evaluated fruit pulps.

The method and temperature of storage of a product are the basic agents that make it possible to prolong the post-harvest life of strawberries. In this context, this study aimed to evaluate the use of different packages with the passive modified atmosphere in the post-harvest quality of strawberry (cv. Camarosa). The strawberries were harvested and subsequently transported to the Laboratory of Drying and Post-harvest Storage of Agricultural Products, where they were stored in BOD, at 0ºC, and 90±5% relative air humidity. A completely randomized design was used, in a 3 x 5 factorial scheme (three packages: expanded polystyrene (EPS) packaging + polyvinyl chloride (PVC) film at 0 °C; polyethylene terephthalate (PET) packaging at 0 °C; and without packaging at 0 °C (control) x five analysis: at 0, 2, 4, 6, and 8 days of storage), with four replications per day for each treatment. Averages were compared by Tukey test at 5% probability. The variables, fresh mass loss, pulp firmness, pH, soluble solids (SS), titratable acidity (TA) and SS/TA ratio were analyzed. The tested packages had better results when compared to the control treatment. The use of polyethylene terephthalate (PET) packages at 0ºC had a less fresh mass loss during storage days, lower acidity reduction, and no significant decrease in pulp firmness.

Iron (Fe) is a micro essential needed by plants in small amounts and can be toxic when available in large quantities. This study aimed to evaluate how Fe exposure affects the growth of C. callothyrsus and L. leucocephala seedlings. This study used a completely randomized design with factorial, where the first factor consisted of two levels of seedlings (C. calothyrsus and L. leucocephala), and the second factor consisted of Fe concentration which consisted of 8 levels (0, 0.25, 0.5, 0.75, 1, 1.25, 1.5, and 1.75 mM). The results showed that treatment of seedlings species and concentration of Fe was able to significantly affect the growth parameters (height, root length, root dry weight, shoots, and plant dry weight) of seedlings. The control treatment (without Fe) showed the highest growth response compared to those treated with Fe exposure and an increase in Fe concentration was able to reduce all growth parameters in both seedlings. The 0.5 mM Fe concentration reduced all growth parameters of C. calothyrsus drastically, while in L. leucocephala, the Fe 0.75 concentration was able to decrease all growth parameters drastically. The tolerance index of both seedlings decreased with increasing Fe concentration. The rate of photosynthesis did not show a significant difference between treatments, meanwhile, it had a significant effect on chlorophyll affect chlorophyll (a, b, and total chlorophyll) and carotenoid content. The highest Fe content in C. calothyrsus seedlings was at a concentration of 1.5 mM (4.40%), while in L. leucocephala seedlings, the highest Fe content was at 1.7 mM (2.87%).
