About 600 species of Passiflora are described around the world, of which 120 are native to Brazil. In the present work, the phytochemical compounds were analyzed by high-performance liquid chromatography, and the antioxidant activities (AOX) were measured in the pulp of P. edulis and P. cincinnata species. The P. edulis presented a higher bioactive content and AOX when compared to P. cincinnata. Citric and malic acids were the main organic acids found. The principal component analysis-PCA associated the highest values of quercetin-3-glucoside, hesperidin, trans-caftaric acid, chlorogenic acid, caffeic acid, p-coumaric acid, trans-resveratrol, rutin, procyanidin-B2, epigallocatechin-gallate and epicatechin-gallate, to P. cincinnata. The P. edulis was associated with higher values of total phenolic, vitamin C, total carotenoids, AOX (DPPH^•, ABTS^+• and FRAP), cis-resveratrol, naringenin, kaempferol-3-glucoside, myricetin and procyanidin-B1. P. cincinnata, although not a commercial species such as P. edulis, presented phenolic compounds and antioxidant activity in acceptable values, including the high values of quercetin 3-glucoside. The present study contributes to the knowledge of the physical-chemical composition of the Passiflora species.

Studying the causes of postharvest fruit loss is important to avoid reduction of quality and quantity for the consumer due, for example, to the influence of frequent impacts from vibrations during transportation. In this sense, this study evaluates the storage quality of ‘Palmer’ mangoes after being subjected to different simulated road transport vibrations. Vibration was simulated from the analysis of the profile of the frequencies generated in road transport of fruit, determined in a tractor trailer. ‘Palmer’ mangoes stored after vibration stress wereevaluated for: mass loss, absorbance difference index (IAD), peel and pulp browning index (BI), pulp firmness, soluble solids content, and titratable acidity. The development of a vibration machine made it possible to satisfactorily simulate specific vibration frequencies. Vibration stress during simulated transport led to accelerated weight loss, decreased pulp firmness, and peel browning in ‘Palmer’ mangoes.

For climacteric fruits, such as mango, losses have been reported from harvest to fruit consumption. Thus, controlled refrigeration and passive modified atmosphere have been used in combination with edible and biodegradable coatings or plastic packaging to minimise these losses. The present study aimed to evaluate the influence of carnauba wax and Xtend plastic packaging film, with and without refrigerated storage, on the post-harvest preservation of 'Tommy Atkins' mangoes. The fruits were coated with carnauba wax and/or wrapped in Xtend bags and then stored at 12 ± 1 and 25 ± 3 °C for 21 days. The weight loss, fruit firmness, total soluble solids, titratable acidity, vitamin C content, and the CO2 concentration inside the package were determined at 7-day intervals. Cold storage was observed to slow down the rate of degradation and to reduce adverse degradation reactions. By coating the fruits with carnauba wax, packaging them with Xtend plastic and keeping them under refrigeration, it was possible to store the mangoes at 12 ± 1 °C for 21 days. In this way, the CO2 concentration was reduced, mass loss and acidity were decreased, and the fruit firmness was preserved.

Verificar a influência do teor de água nos valores da força máxima de compressão para deformações fixas e determinar o módulo proporcional de deformidade de grãos de feijão submetidos a compressão em três diferentes posições, foram os principais objetivos que estimularam o presente trabalho. Para isto, utilizaram-se grãos de feijão com teores de água variando de 0,13 a 0,45 (b.s.) comprimidos uniaxicialmente, entre duas placas paralelas, na direção de suas três dimensões essenciais. A partir dos resultados obtidos, conclui-se que a força de compressão necessária para deformar o feijão diminui com o aumento do teor de água, sendo maior para a direção perpendicular à divisão dos cotilédones (posição natural de repouso). O módulo proporcional de deformidade aumenta com a redução do teor de água e da deformação do produto, obtendo-se valores para a faixa de umidade estudada, entre 1,7 x 10(7) a 71,3 x 10(7) Pa, dependendo da posição do grão.
