“…In this context, Oliveira et al (2017) evaluating the postharvest quality in the conservation of jambu according to the type of packaging and hydrothermal treatment, also observed that the reduction of the jambu temperature, through cooling, as well as the use of plastic packaging can prolong the shelf life of this hardwood. They reached this conclusion when they evaluated these treatments and verified that these, individual or associated, caused the plant to present less water loss at the end of storage, which was 12 days.…”

Coriander is among the most consumed aromatics in brazilian northeast and for Its particular aroma It is used in the composition of regional recipes. Just like other leafy greenery, postharvest improper coriander storage, compromises Its process of commercialization, being nessessary a low cost technology research that intends to increase coriander's shelf life. In this sense this research had as objective to verify the efficiency of packaging, storage temperature and postharvest sanitation treatment for commercialization purpose. The experiment was conducted in completely randomized experimental design in factorial scheme 4x2x2, with four repetitions, represented by 4 packaging types (PVC film, paper towel, PVC film + paper towel and plastic bag-LDPEB, two storage environments (refrigerated at 10°C and at room temperature of 25°C) and two sanitization treatments (with and without sanitization). The coriander packs of 50g were treated and stored for 10 days according to each environment condition. After storage period, the coriander was rated for Its final fresh mass and Its quality for commercialization, based on the parameters: coloring, darkening, odor and overall quality. It is concluded that refrigerated storage contributed to minimize storage damages in all sensory qualities, specially when associated to the use of the plastic bag. The fresh mass was individually influenced by the type of packaging, sanitization and storage conditions where there was less mass loss under refrigeration conditions and in plastic bag (LDPEB), but as for the dry mass, sanitization was not efficient when coriander was conditioned to room temperature.

“…A perda de massa em produtos hortícolas consiste na redução do peso fresco do produto ao longo do tempo e está diretamente relacionada à movimentação de água no produto após a colheita, determinadas pela perda de água por transpiração. Esse intenso processo de transpiração ocasiona um déficit e o produto perde água para o ambiente iniciando um estresse hídrico que tem por características a perda de turgidez e a redução do peso fresco (OLIVEIRA et al, 2017;SANCHES et al, 2017).…”

A floricultura constitui um dos segmentos mais dinâmicos do agronegócio e a utilização de arranjos florais exige alto padrão de qualidade de seus produtos e uma maior longevidade pós-colheita das flores. A quitosana é um polissacarídeo biodegradável capaz de formar um filme natural e permeável às trocas gasosas realizadas pelo vegetal, permitindo a redução do metabolismo da planta favorecendo o prolongamento de sua vida útil. Este estudo teve como objetivo avaliar a durabilidade pós-colheita de folhas de Strelitizia reginae e Strelitizia juncea utilizando produto comercial a base de quitosana (FishFertil®). O experimento foi conduzido inteiramente casualisado de 6 tratamentos com 5 repetições (onde cada folha foi considerada como uma repetição). Foram utilizadas 6 doses ( 0 ; 10 ; 20 ; 40 ; 80 e 160 mg L-1 do produto comercial). Realizaram-se avaliações visuais da longevidade das folhas através de notas e o acompanhamento da perda de água nos tecidos foliares. Observou-se que FishFertil® retardou a perda de massa fresca das folhas de S. juncea e S. reginae. Para ambas as espécies o tratamento controle permaneceu até o 22° dia com notas aceitáveis comercialmente (nota 4). O produto retardou a perda de massa fresca das folhas de S. juncea e S. reginae e as mantiveram até o 34° dia notas dentro do padrão comercial, contudo não foi possível determinar a dose de máxima eficiência do produto para as duas espécies de Strelitzia.

“…The subjective assessment provides information on the physical quality of leafy vegetables because by being chosen by consumers, they are judging in some way whether the overall appearance of the product meets their expectations and requirements (Oliveira et al, 2017). The appearance attribute is of fundamental importance for marketing, as the consumer makes the purchase decision based on the physical aspect of arugula leaves.…”

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.
