| Abstract: The objective of this work was to evaluate the physicochemical attributes and vitamin C contents of fruits of five Brazilian genotypes of feijoa (Acca sellowiana), at harvest and after cold storage. The Alcântara, Mattos, Helena, and Nonante cultivars, as well as accession 2316, were studied. The assessed attributes were: fresh mass loss, titratable acidity, soluble solids contents, soluble solids contents/titratable acidity ratio, pH, skin and flesh color, texture, and vitamin C contents (skin and flesh). After storage, there were reductions of 2.9% in soluble solids contents, of 32.2% in titratable acidity, and of approximately 85% in texture attributes, besides increases of 36.3% in the soluble solids contents/titratable acidity ratio and of... |

| Abstract: The objective of this work was to evaluate the influence of harvest at maturity on the composition, quality, and postharvest life of zapallito squash (Cucurbita maxima var. zapallito). Fruit were harvested at three developmental stages - small, medium, and large, with 30, 70, and 90±10-mm diameter, respectively - and were stored at 0 and 5°C for 26 days and, then, at 20°C for 2 days. The following parameters were determined: respiration, firmness, color, chlorophyll content, carotenoids, sugars, acidity, phenolic compounds, antioxidants, decay, mass loss, and chilling injury (CI). Small light-colored squashes were more prone to dehydration and decay. Delaying harvest markedly reduced fruit carotenoid contents, acidity, and respiration rate;... |

| ABSTRACT The use of mechanization in the harvesting of industrial tomatoes provides greater yield and speed of this stage. However, mechanical intervention in this process may alter the physiology of harvested fruits. Therefore, the objective of this study was to measure the quantitative losses of tomato fruits and to verify the physico-chemical behavior of fruits harvested based on physicochemical analysis in harvesters with different hours of use. Three self-propelled harvesters of the same brand and model with different working hours were used. Manually selected or undamaged fruits were harvested; afterwards, mechanized harvesting was carried out. Firmness, titratable acidity, soluble solids content (°Brix), pH, weight loss and fruit status... |

| ABSTRACT In this study, oranges of the cultivar ‘Valencia Delta’ were degreened, coated with carnaúba-based wax and stored under refrigeration. The influence of the application of exogenous ethylene and coating was observed on physical and physico-chemical properties of the fruits. After the application of the treatments, the fruits were refrigerated (7 ± 2 oC) for a period of 35 days. The analyzed variables included weight loss, peel color, titratable acidity, ascorbic acid, total soluble sugars, reducing sugars, total polyphenols and total chlorophyll of the peel. The coated fruits showed significant reduction in weight loss when compared with the uncoated fruits, which lost about 3.0% of moisture at the end of the experiment. Significant reduction in... |

| Abstract This study aimed to evaluate the storage potential of SCS426 Venice apples under different storage technologies. Fruits were harvested in an experimental orchard located in Fraiburgo, SC and stored for up to eight and ten months in 2013 and 2014, respectively. Apples were treated or not with methylcyclopropene (1-MCP) and stored under air atmosphere (AA, 0.5±0.5 °C/RH 85±5%) or controlled atmosphere (CA; 1.5 kPa of O2 and 1.5 kPa of CO2 at 0.7±0.5 °C/RH of 93±3%). Fruits were evaluated every two months of storage, after one and seven days of shelf life (23 ± 0.3 °C/RH 93±3%). The storage period of ‘SCS426 Venice’ apples under AA without 1-MCP application should not extend beyond six months. Under this storage condition, fruits had higher... |

| Abstract One of the great challenges of the mango production chain is the maintenance of post-harvest quality of this fruit for export with a focus on food safety. This study evaluated the effect of the hydrothermal treatment associated to ethanol on mango’s quality. Two tests were performed, in both were used ‘Tommy Atkins’ mangoes. In the first one, the heat treatment consisted of immersing the fruits in a bath at 46.1 °C / 75 minutes with ethanol concentrations of 0, 5, 10 and 20% v / v, then a cooling bath at 21.1 °C / 30 minutes and stored at 25 °C. In the second, fruits were submitted to the baths, but with ethanol concentrations of 0, 3, 5 and 7% v/v, and stored at 25°C and 10°C. Physical-chemical and phytopathological analysis and percentage of... |

| ABSTRACT Grape juice has been widely studied due to the presence of phenolic compounds and its beneficial effects on human health. Ultraviolet irradiation C (UV-C) can increase the content of phenolic compounds and anthocyanins and contribute to sensory acceptability. The aim of this study was to evaluate the effect of different doses of ultraviolet irradiation C (UV-C) on ‘Trebbiano’, ‘Niagara Branca’, ‘Isabel’ and ‘Cabernet Sauvignon’ grapes, as well as effect of the storage period. Juices were elaborated and evaluated for physicochemical analyses, and for the sensorial analysis in irradiated samples. In ‘Niagara Branca’ and ‘Trebbiano’ cultivars, storage and irradiation promoted few physicochemical alterations, and sensorially, irradiation reduced the... |
