'Royal Gala' apple quality stored under ultralow oxygen concentration and low temperature conditions

Abstract: -The objective of this work was to evaluate the interaction of ultralow oxygen concentrations (ULO) with storage temperatures and carbon dioxide partial pressures and its influence on fruit quality preservation and on the occurrence of physiological disorders in 'Royal Gala' apples. The experiment was carried out in a completely randomized design, with four replicates 25-fruit. ULO conditions (1.0 kPa O 2 + 2.0 kPa CO 2 ; 0.8 kPa O 2 + 1.5 kPa CO 2 ; 0.8 kPa O 2 + 1.0 kPa CO 2 ; 0.6 kPa O 2 + 1.5 kPa CO 2 ; an… Show more

“…are stored after harvest under CA conditions with about 1.0 to 1.2 kPa O 2 and 2.0 to 2.5 kPa CO 2 at a low temperature (0.5 to 1 °C), and relative humidity of about 94 %, for up to seven months (Weber et al, 2011;. If oxygen levels are excessively reduced, hypoxic and even anoxic zones may develop and switch from aerobic respiration to fermentation, which can lead to physiological disorders (Pesis, 2005;Gasser et al, 2010).…”

“…Para reduzir tais perdas, são utilizadas técnicas auxiliares a AC, como a aplicação do composto químico 1-metilciclopropeno (1-MCP) . Recentemente, tem-se investigado técnicas como estresse inicial por baixo O 2 e armazenamento em ultrabaixo oxigênio (ULOultra low oxygen) como forma de manter a qualidade e reduzir a aplicação de produtos químicos em pós-colheita (SABBAN-AMIN et al, 2011;WEBER et al, 2011;BRACKMANN et al, 2012).…”

“…Para a cultivar Royal Gala a temperatura recomendada para o armazenamento em AC varia de 0,5 a 1,0 °C (BRACKMANN et al, 2009;WEBER et al, 2011). A redução da temperatura diminui o metabolismo durante o armazenamento, porém uma redução excessiva pode levar ao colapso das células, tornando os frutos suscetíveis à ocorrência de distúrbios .…”

“…De acordo com Lévesque, DeEll e Murr (2006), o condicionamento, pela redução gradual na concentração de O 2 , provoca uma adaptação dos frutos ao baixo O 2 . Dessa forma, seria possível diminuir a concentração de O 2 durante o armazenamento abaixo dos níveis indicados pela literatura para a cultivar Royal Gala (1,0 kPa) (BRACKMANN et al, 2009;WEBER et al, 2011), o que diminuiria o metabolismo, sem causar distúrbios.…”
