“…Stem scar region is an important pathway for water loss in tomato fruit. In apple, lenticels account for up to 21% of the transpiration (Maquire et al 2001). Complete coating of fruit was found to retard gaseous exchange by plugging the stomatal pores of citrus (BenYehoshua et al 1985).…”

Role of internal atmosphere on fruit ripening and storability—a review

Concentrations of different gases and volatiles present or produced inside a fruit are determined by the permeability of the fruit tissue to these compounds. Primarily, surface morphology and anatomical features of a given fruit determine the degree of permeance across the fruit. Species and varietal variability in surface characteristics and anatomical features therefore influence not only the diffusibility of gases and volatiles across the fruits but also the activity and response of various metabolic and physiological reactions/processes regulated by these compounds. Besides the well-known role of ethylene, gases and volatiles; O 2 , CO 2 , ethanol, acetaldehyde, water vapours, methyl salicylate, methyl jasmonate and nitric oxide (NO) have the potential to regulate the process of ripening individually and also in various interactive ways. Differences in the prevailing internal atmosphere of the fruits may therefore be considered as one of the causes behind the existing varietal variability of fruits in terms of rate of ripening, qualitative changes, firmness, shelf-life, ideal storage requirement, extent of tolerance towards reduced O 2 and/or elevated CO 2 , transpirational loss and susceptibility to various physiological disorders. In this way, internal atmosphere of a fruit (in terms of different gases and volatiles) plays a critical regulatory role in the process of fruit ripening. So, better and holistic understanding of this internal atmosphere along with its exact regulatory role on various aspects of fruit ripening will facilitate the development of more meaningful, refined and effective approaches in postharvest management of fruits. Its applicability, specially for the climacteric fruits, at various stages of the supply chain from growers to consumers would assist in reducing postharvest losses not only in quantity but also in quality.

“…Total weight loss from a plant tissue is the integral of rates of weight loss at any particular time over the period following harvest (Maguire et al, 2001). As argued by Labuza (1982), given a historic of the storage conditions, it is possible to divide the whole period in small intervals (t j ) in which these storage conditions are considered constant.…”

“…Indeed, the chemical potential of water in cells compared with that in the adjacent air determines the direction for net water movement occurring at cell-air interface (Nobel, 2005;Shamaila, 2005). Subsequently, the plant releases this water vapor into the surrounding atmosphere through a moisture transport known as epidermal transpiration (Maguire et al, 2001;Veraverbeke et al, 2003). Plant transpiration is affected by both fruit characteristics (e.g.…”

“…Neste tratamento, a elevação da temperatura, mesmo com a utilização de elevada umidade relativa (80-90% no interior das câmaras BOD), ocasionou aumento no défi cit de pressão de vapor de água (DPVA) entre o fruto e o ar da câmara, ocasionando a desidratação (Maguire et al, 2001). A utilização de fi lmes plásticos, independentemente do tipo, reduziu a perda de massa fresca (Tabela 2), refl etindo a formação de ambiente saturado de umidade no interior da embalagem, reduzindo o DPVA e assim a transpiração (Malgarim al., 2006;Mota et al, 2006).…”

Preservação da qualidade pós-colheita de araçá-vermelho através do tratamento com 1-metilciclopropeno e do acondicionamento em embalagens plásticas, sob refrigeração

2009

O objetivo deste trabalho foi estudar o padrão respiratório e de produção de etileno, e os efeitos do tratamento com diferentes doses de 1-metilciclopropeno (1-MCP) e do acondicionamento em diferentes embalagens plásticas, associado à refrigeração, na preservação da qualidade pós-colheita de araçá-vermelho. Os frutos apresentaram comportamento climatérico de respiração e produção de etileno. Frutos tratados com doses crescentes de 1-MCP (0; 100; 300; 600 e 1.200 nL L-1) e armazenados a 10±1C/90±5% UR, durante 10 dias, apresentaram retardo substancial no amadurecimento, através da preservação da textura e inibição na mudança de cor da epiderme. Frutos acondicionados com diferentes filmes (polietileno de baixa densidade, policloreto de vinila e à base de náilon) apresentaram, em termos gerais, melhor preservação da textura e menores mudanças na cor da epiderme e perdas de massa fresca, durante armazenamento refrigerado (5C e 10C). Os resultados demonstram que os frutos de araçá-vermelho apresentam elevada perecibilidade, caracterizada pelas elevadas taxas respiratórias e de produção de etileno, sendo mais bem preservados quando refrigerados, e tratados com 1-MCP ou acondicionados em embalagens plásticas.
