Five mangos cultivars (Mangifera indica L., `Palmer', `Keitt', `Spring Field', `Kent', and `Anderson') were harvested at the preclimacteric stage. Fruits were selected for study that were uniform and free of visual defects and stored for 18 days at 10 °C, 90% to 95 % RH. Fruits were evaluated every 3 days for pulp and peel color, total soluble solids, titratable acidity, ascorbic acid content, and total and reducing sugars. Pulp and peel color parameters (lightness, hue, and chroma) were significantly different among cultivars. The soluble solids content, ascorbic acid, and starch content changed significantly during storage and were significantly different among cultivars. Total and reducing sugars content did not change significantly after 10 days of storage. Results of this study indicated that these five mango cultivars have good storage potential.

This study aimed to evaluate the postharvest behavior of peach cv. Aurora 1 harvested in the Zona da Mata region of Minas Gerais in two ripening stages and kept under different storage temperatures. Fruits on mid-ripe and fully ripe stages were stored at three temperatures: 5.6 ± 1.57 °C and 72.8 ± 3.8% RH; 10.4 ± 0.5 °C and 95.8 ± 5.5% RH; 21.04 ± 1.63 °C and 96.9 ± 2.6% RH up to 28 storage days (SD) . During storage, fruits stored at 21.04 ± 1.63 °C were evaluated every two days until 8 SD, and every four days for fruits stored at other temperatures. The harvest day was assigned as day zero. The variables evaluated were CO2 production, color of the pericarp and pulp, fresh mass loss, flesh firmness, total soluble solids, titratable acidity, contents of ascorbic acid and carotenoids. The fresh mass loss increased during storage, peaking at 5.6 °C. The reduction in ascorbic acid content was higher in fully ripe fruits at all temperatures. Mid-ripe fruits reached the end of the storage period with better quality. The temperature of 10.4 °C was the most efficient in keeping postharvest quality of peach cv. Aurora 1 harvested in the Zona da Mata region.

Abstract The physicochemical characteristics of fruits of species native to the Atlantic Forest are little known, especially during ripening. The aim of this work was to evaluate the effect of the interaction between ripening period and post-harvest storage of araçaúna and grumixama. Fruits were harvested at three ripening stages: green, partially ripe and ripe, according to the epicarp color, and separated into two groups, being stored for 2 and 48 hours. The following variables were evaluated: longitudinal (LD) and cross-sectional (CD) diameter, LD / CD ratio, fresh fruit mass (FM), pulp yield (PY), pH, soluble solids content (SS), titratable acidity (TA), SS / TA ratio, and ascorbic acid content (AA). Araçaúna fruits stand out due to their high PY (74.43%), with low SS (2.07 ºBrix) and high TA (1.17% citric acid). However, harvesting fully ripe fruits increases SS by 21% and reduces TA by 32.5%. Grumixama fruits are slightly sweet (6.06 ºBrix), with low acidity (0.39% citric acid), high vitamin C content (206.94 mg of ascorbic acid/100g of pulp), and harvest must be performed when fruits are fully ripe. Both species have pulp of potential quality to be commercially exploited, especially for processing.

In this study, the effect of postharvest salicylic acid (2 mM), oxalic acid (5 mM), putrescine (2 mM) and calcium (4% CaCl2) applications on storage performance of Autumn Giant plum fruit were investigated. After applications, plum fruits were placed in modified atmosphere packaging (MAP) and stored for 40 days at 85-90% relative humidity conditions at 0.5±0.5°C. In order to determine the fruit quality characteristics after treatments, weight loss, soluble solids content, titratable acidity, fruit firmness, ascorbic acid, total flavonoids, total phenolics and total antioxidant content analysis were performed at 10 days’ intervals. According to the results, the effect of applications on weight loss was not significant. The maximum decrease in flesh firmness, titratable acid and ascorbic acid content during storage was determined in control fruits. Although fluctuations in the form of increase or decrease in biochemical compounds were generally observed, decreases occurred according to harvest value at the end of storage period. Considering all measurements and evaluations, it was determined that application of salicylic acid and putrescine had a more positive effect on preservation of fruit quality properties and biochemical content of Autumn Giant plum cultivar during storage than other applications.

The Impact

Brazil is the world’s largest orange producer; however, part of this production is lost during postharvest. This loss can be minimized by controlling incidence of physical damage throughout the harvest and loading operations. Impacts can negatively modify quantitative and qualitative fruits aspects. The main goal of this study was to measure the impact magnitude in two types of harvest (manual and detachment) and during all steps from picking into bags until loading for transport to the processing industry and additionally evaluating, in laboratory, the physico-chemical quality of the fruit subjected to various impacts, similar to those found in the field. In order to evaluate the impact magnitude, an instrumented sphere was used (760 mm, Techmark, Inc, USA). The following physico-chemical parameters were evaluated during 6-days of storage: weight loss, soluble solids contents, titratable acidity, ascorbic acid content, pH, firmness and peel color. The greatest impacts were observed during harvest, during the detachment practice, and when loading and unloading from bulk storage, with average acceleration values between 249.5 and 531.52G. The impact incidence in oranges were responsible for reducing the soluble solids, titratable acidity, ascorbic acid and weight by to 5.5%; 8.7%; 4.6% and 0.5%, respectively, compared to the control. Impacts during harvest and the various pre-industry manipulation steps must be controlled as they interfere in postharvest quality and physiology of ‘Valência’ oranges.

ABSTRACT Mineral nutrients have important role in plant metabolism, acting on specific vital metabolic pathways for the cell. Among the nutrients, we highlight silicon (Si), for promoting growth, improving post-harvest quality and plant productivity, as well as being able to induce resistance to pest and disease. In this sense, this study aimed to evaluate the productivity and post-harvest quality of strawberry fruits cultivars Aromas and Albion cultivated in organic system with four doses of foliar applications of SiO2 in pre-harvest (0, 5, 10, 15 g L-1), and refrigerated storage (8 days under refrigeration and 1 day at room temperature). The valuated traits were: mass loss, fruit mass, productivity, fruit firmness, soluble solids, titratable acidity, total phenolics, total anthocyanins, ascorbic acid and soluble solids titratable acidity ratio. The cultivar Aromas presented higher productivity per area (33.05 t ha-1), and more fruits per plot (479.42); however, higher average fruit mass was obtained in cultivar Albion (24.44 g), presenting better-quality fruits for fresh market. Soluble solids content, SS/TA ratio and ascorbic acid content were not influenced by silicon doses, however, refrigeration during 8 days and 1 day at room temperature provided reduction of fruit firmness, titratable acidity and, ascorbic acid content and increased soluble solids content and SS/TA ratio. Refrigeration attenuated significant reductions in anthocyanin content and, in addition, foliar silicon application promoted higher levels of anthocyanins in the fruits of both strawberry cultivars, increasing with the applied dose. The application of silicon was also efficient in maintaining fruit firmness of both cultivars.

ABSTRACT: Brazilian Cerrado fruits have a great diversity of bioactive compounds, with significant relevance for fresh consumption and industrial processing. The uvaia (Eugenia pyriformis Cambess) stands out among these fruits, seeing that this species contains high phenolic compounds and ascorbic acid levels. However, its technological and nutritional potential is still little explored industrially. This research aimed to develop three uvaia nectar formulations and to evaluate its stability during 90 days of storage. The formulations were made with 30%, 40%, and 50% of uvaia pulp, corresponding to F1, F2, and F3 formulations, respectively, which were characterized for pH, total titratable acidity, soluble solids, ascorbic acid, and total phenolics during 0, 30, 60, and 90 days of storage at room temperature. A significant pH reduction was observed after 30 days of storage for all nectars. The acidity and ascorbic acid levels increased in proportion to the addition in the pulp concentration of the formulations. The ascorbic acid content reduced over the storage period and remained higher for the formulations F2 and F3. The concentration of phenolic compounds was higher in the nectar containing relevant levels of uvaia pulp concentration, which increased throughout 30 days of storage, however, with a decrease after this period. The formulations containing 40% and 50% of uvaia pulp showed higher concentration and better stability of bioactive compounds. Uvaia can be considered an effective raw material for the development of a novel beverage with important nutritional and bioactive properties.

Extraction of tropical fruit juice using simple, efficient, and environmentally friendly technologies is gaining importance to produce high quality juices. Juice from pink-fleshed guava, pink-fleshed pomelo, and soursop was extracted using direct and indirect thermosonication methods by varying intensity, time, and temperature, and compared to those extracted using water bath incubation. Improvised models of juice yield, ascorbic acid, and total soluble solids responses were generated by eliminating insignificant model terms of the factors in full quadratic model using backward eliminating procedure. Main effects, 3D, or 4D plots for each response were developed based on factors that influenced the response. Results showed that the best extraction method for guava and pomelo juices were within indirect thermosonication method of 1 kW, 55 °C and 30 min, and 2.5 kW, 54 °C and 23 min, respectively. Direct thermosonication method at 10% amplitude, 55 °C for 2 to 10 min was more suitable for soursop juice. Thermosonicated extraction of tropical fruit juice can improve its juice yield, ascorbic acid content, and total soluble solids content.

'Aurora-1' peaches establishes an interesting alternative as a minimally processed product, due to its characteristics like flavor, color, smell, and also because of its handling resistance. However, it has a short shelf life after a fresh-cut due to enzymatic browning and stone cavity collapse. The main purpose of this research was to test the additive with antioxidant effect to prevent browning in minimally processed 'Aurora-1' peaches. The minimal processing consists of washing, sanitizing, peelings and fruit stone extraction. After that, longitudinal cuts were made to obtain eight segments per fruit. The slices were immersed into the following treatment solutions: control (immersion in 2% ascorbic acid); 2% ascorbic acid + 2% calcium chloride; 1% sodium isoascorbate; 1% citric acid; 1% L-cysteine hydrochloride. The products were placed into rigid polystyrene trays branded MEIWA M-54, covered with 14 µm PVC film (OmnifilmTM) and kept in cold storage at 3ºC ± 2ºC and 65% RH for twelve days, and evaluated each three days. Appraised variables were appearance, soluble solids, titratable acidity, soluble carbohydrates and reducing sugars, total and soluble pectin, ascorbic acid, and peroxidase and polyphenol oxidase enzyme activity. L-cysteine gave to the minimally processed products a shelf life of twelve days, limmited by off-flavor. The treatment with ascorbic acid was efficient to maintainthe ascorbic acid content, with a shelf-life of nine days, limited by enzymatic browning.
