“…The value obtained for "Fuyu" persimmon fruit (5.33) in this study was lower than the one observed by Brackmann et al (2013) in Rio Grande do Sul, Brazil. The "Rama Forte" persimmon fruit in this study show similar results with the same crops growing in Jundiaí (São Paulo, Brazil) conditions (Mendonça et al, 2015). These results can be due to climate condition variations and experimental site, but could be also due to the fruit"s ripening stage and harvesting season.…”

The aim of this study is to evaluate the phenology, yield and fruit physicochemical characteristics of four persimmon cultivars (Diospyros kaki L.) in São Paulo's Midwest countryside, Brazil. The persimmon cultivars studied were 'Pomelo', 'Rama Forte', 'Fuyu' and 'Rubi'. The main phenological phases of persimmons trees were evaluated. Despite significant differences between cultivars in the early and intermediate stages of the plants development such as branch development, full blossom and fruiting's onset, the time required between the fruit's pruning and harvesting was similar among the cultivars. It could be observed that only 'Pomelo' persimmon trees presented male flowers. However on 'Rubi', 'Fuyu' and 'Rama Forte' persimmons trees were found the largest number of female flowers, fruits fixation index and number of fruits per branch. Nevertheless, there were no differences among the cultivars regarding productivity, which could be due to the persimmon fruits physical characteristics. The fruits' diameter growth behavior was evaluated and it was observed that all cases were defined as double sigmoidal, defined by three single phases. Regarding the chemical characteristics, there were no differences among the cultivars' pH and soluble solids content; however, in general, the 'Pomelo' persimmon fruit presented less titratable acidity and a higher maturation index rating.

“…Decréscimo significativo no ângulo hue indica que a cor do produto se torna escura. A cor é um atributo importante na aparência comercial dos produtos vegetais, sendo um fator determinante no poder de aceitação de compra pelo consumidor (MENDONÇA et al, 2015). Apesar de ter ocorrido variação significativa nos valores de ângulo hue durante o armazenamento, visualmente não foi observada variação na coloração das raízes submetidas aos diferentes tratamentos, confirmando as informações obtidas nas demais variáveis analisadas sobre a cor do produto.…”

Resumo As raízes de mandioca de mesa minimamente processadas surgiram como uma alternativa para aumentar a vida útil pós-colheita do produto e disponibilizar um alimento mais prático e seguro para os consumidores. O Distrito Federal e entorno está se tornando um grande produtor e consumidor de mandioca de mesa. Dessa forma, objetivou-se determinar os efeitos de diferentes concentrações de ácido cítrico (0,5%, 1,0%, 1,5%, 2,0%, 2,5%) para a conservação de raízes de mandioca IAC 576-70 minimamente processadas, imersas em água. O produto foi mantido na temperatura de 3 °C por 35 dias. Na matéria-prima e durante o armazenamento, realizaram-se análises de pH, acidez titulável, sólidos solúveis, ratio, tempo de cocção, cor e textura das raízes. A ação do ácido cítrico na vida útil do produto foi positiva em todas as concentrações estudadas, durante todo o armazenamento. Em todas as concentrações de ácido cítrico avaliadas, ocorreu redução significativa nos valores de pH e aumento da acidez titulável, sendo esta menos acentuada no produto submetido à menor concentração (0,5%). Visualmente, não foi observada a presença de microrganismos nas raízes de mandioca minimamente processadas e na água de imersão.

“…The evaluation of vegetable conservation capacity has been performed to determine the efficiency of conservation methods concerning the protection of vegetables against oxidation and loss of commercial and nutritional value. The postharvest quality parameters used are physical, such as fresh mass loss, color and appearance, and chemical parameters such as soluble solids, pH and titratable acidity (Mendonça et al, 2015).…”

Arugula is mainly cultivated by small producers, being a leafy vegetable susceptible to water loss and wilting after harvest, which may result in changes in appearance, texture, color (yellowing), and nutritional value of the product. Hydrocooling is a cooling method that stands out for being simple, practical and efficient. Its use is to reduce the temperature and respiratory rate of vegetables after harvesting by immersion in ice or cold water, so they can be packed and stored. This study was conducted to evaluate the hydrocooling efficiency when associated with the storage period in the postharvest shelf life of arugula leaves. Arugula leaves were subjected to ten days of storage, and measurements were taken at 0, 2, 4, 6, 8 and 10 days. The experimental design was completely randomized in a 3 × 6 factorial scheme, consisting of three hydrocooling treatments [control (without cooling), and hydrocooling at 0 °C and 10 °C] and for six storage periods (0, 2, 4, 6, 8 and 10 days) with three replicates. Fresh mass loss, soluble solids, titratable acidity, pH and subjective evaluation of product appearance were measured. Hydrocooling at 0 °C proved to be the most appropriate treatment when compared to control, as reported by the values of fresh mass loss, soluble solids, and titratable acidity. Hydrocooling to 0 °C slowed leaf water loss (lower respiratory rate) and resulted in better overall leaf appearance up to the sixth day of storage, thereby increasing shelf life of arugula leaves.
