| Resumo: O objetivo deste trabalho foi avaliar o efeito da temperatura de armazenamento sobre a manutenção da qualidade, o teor de compostos fenólicos e a atividade antioxidante de amoras-pretas (Rubus sp.) 'Tupy' e 'Guarani'. Os frutos foram armazenados a 0, 5, 10 e 15°C. Após cinco dias de armazenamento, as amoras-pretas foram avaliadas quanto aos seguintes parâmetros: cor da epiderme, taxa respiratória, perda de massa, força para compressão, acidez titulável (AT), sólidos solúveis (SS), relação SS/AT, podridões, compostos fenólicos totais (CFT) e atividade antioxidante (AAT). O aumento da temperatura de armazenamento causou, em ambas as cultivares, o aumento da taxa respiratória, da perda de massa e da incidência de podridões, bem como redução dos teores... |

| Abstract The objective of this work was to evaluate the effect of ethanol vapor during storage in modified atmosphere on the ripening and maintenance of the postharvest quality of ‘Laetitia’ plums. The plums were obtained from an orchard in the municipality of Lages, SC. The experimental design adopted was completely randomized. The treatments evaluated were ethanol vapor doses (0, 2, 4, 6 and 8 mL kg-1 of fruit). The fruits were stored at 0.5±0.2°C and 92±2% RH for 30 days. Upon their removal from storage followed by another three days in room conditions (20±5ºC and 63±2% RH), the fruits were evaluated in relation to their physical and chemical attributes, incidence and intensity of internal browning, quantification of ethanol, acetaldehyde and ethyl... |

| Abstract The aim of this work was to evaluate the effect of single and multiple pre-harvest spray aminoethoxyvinylglycine (AVG) applications with or without ethephon, in ‘Baigent’ apple trees cultivated under anti-hail screen and harvesting date on fruit quality after storage. The experiment was conducted in a commercial orchard in the municipality of Vacaria/RS, in the 2014/15 and 2015/16 harvests. Treatments consisted of: control (plants sprayed with water); AVG (125 mg L-1, 30 days before the predicted harvest date; BPHD); ethephon (120 mg L-1, seven BPHD); AVG (62.5 mg L-1 + 62.5 mg L-1, 30 and 20 BPHD); AVG (62.5 mg L-1 + 62.5 mg L-1, 30 and 20 BPHD) + ethephon (120 mg L-1, seven BPHD). Fruits of all treatments were harvested at commercial harvest... |

| Abstract The aim of this work was to evaluate the effect of storage temperature, in passive modified atmosphere (MA) and atmospheric composition in active MA on quality maintenance, total phenolic compounds (TPC) and total antioxidant activity (TAA; DPPH and ABTS methods) of ‘Tupy’ blackberry. Two experiments were carried out. In experiment 1, the fruit were stored for eight days at 0, 5 and 10 °C in passive MA. In experiment 2, the initial atmospheres of 21.0 kPa O2 + 0.04 kPa CO2 (passive MA); 9.2 kPa O2 + 9.2 kPa CO2 (active MA with high CO2); 1.4 kPa O2 + 0.04 kPa CO2 (active MA with low O2); and 1.4 kPa O2 + 9.6 kPa CO2 (active MA with low O2 + high CO2) were evaluated for eight days at 0 °C. In both experiments, the fruit were packed in Xtend®... |

| ABSTRACT: The purpose of this study was to evaluate the physicochemical characteristics and functional properties of "dedo-de-moça" 'BRS Mari' pepper fruits at different maturity stages, and determine the ideal harvest stage for fresh consumption. The pepper plants were grown in the experimental field of Embrapa Hortaliças (Brasília, DF, Brazil) in 2012, and their fruits were evaluated at 20, 30, 40, 50, 60, 70, and 80 days after anthesis (DAA) to determine the soluble solid content (SS), titratable acidity (TA), SS/TA ratio, color (hue angle and lightness), a, b, and total chlorophyll, total phenolic compounds (TPC), total antioxidant activity (TAA), and capsanthin. It was observed that SS content increased until 70 DAA, and TA increased until 50 DAA,... |
