“…These results support recommendations of O 2 and CO 2 concentrations for green banana storage in a range of 2-5% [12,13]. Nevertheless, a decrease of O 2 down to 2% before ethylene treatment can result in inferior banana aroma owing to inhibited volatile ester formation [14].…”

Quality problems occurring during or after sea transportation of bananas in refrigerated containers are mainly caused by insufficient cooling and non-optimal atmospheric conditions, but also by the heat generated by respiration activity. Tools to measure and evaluate these effects can largely help to reduce losses along the banana supply chain. The presented green life model provides a tool to predict the effect of deviating temperature, relative humidity, and CO 2 and O 2 gas concentrations on the storage stability of bananas. A second thermal model allows evaluation of the cooling efficiency, the effect of changes in packaging and stowage and the amount of respiration heat from the measured temperature curves. Spontaneous ripening causes higher respiration heat and CO 2 production rate. The resulting risk for creation of hot spots increases in positions in which the respiration heat exceeds the available cooling capacity. In case studies on the transport of bananas from Costa Rica to Europe, we validated the models and showed how they can be applied to generate automated warning messages for containers with reduced banana green life or with temperature problems and also for remote monitoring of the ripening process inside the container.

“…Controlled/modifi ed atmospheres (CA/MA) are known to extend the postharvest life and maintain fruit quality in addition to other benefi ts such as alleviation of CI in many tropical and subtropical fruits including guava Yahia, 1998;Yahia and Singh, 2009). The responses of guava fruit to short-and long-term MA storage have been found positive to extend postharvest life and maintain quality.…”

“…Lower O 2 and higher CO 2 also helped retain flavors and vitamins by reducing acidity loss, starch to sugar conversion, sugar interconversion, and aromatic volatile biosynthesis ( Yahia and Singh, 2009 ). However, O 2 and CO 2 stress reduced cytoplasmic pH, adenosine triphosphate (ATP), and pyruvate dehydrogenase activity while inducing pyruvate decarboxylase, alcohol dehydrogenase, and lactate dehydrogenase, thus shortening the storage life of fresh produce ( Ke et al., 1994 , 1995 ).…”

This research investigated the effect of different atmosphere storage conditions on 1-aminocyclopropane-1-carboxylic acid (ACC) synthase and ACC oxidase enzyme activity; and senescence of cut Dendrobium orchid flowers. The atmosphere storage conditions under study were normal atmosphere, modified atmosphere packaging, and controlled atmosphere. Under the normal atmosphere, carbon dioxide (CO 2 ) and oxygen (O 2 ) concentrations were 0.03 and 21 %, respectively. For the modified atmosphere packaging, cut orchid flowers were wrapped in polypropylene film prior to filling with 5 % CO 2 and 2 % O 2 , while under the controlled atmosphere, CO 2 and O 2 concentrations were maintained at 5 and 2 %, respectively. The storage temperature and relative humidity were 13 °C and 95 %, respectively. The ACC synthase and ACC oxidase activity and ethylene-induced electrolyte leakage were determined and results compared. The controlled atmosphere substantially lowered ACC synthase and ACC oxidase activity and was effective in delaying senescence of cut orchid flowers, as indicated by the longest storage life of 28.33 days, followed by the modified atmosphere packaging (18.15 days) and normal atmosphere (11.67 days). The longer storage life enables suppliers of orchid flowers to efficiently manage the demand and supply and also provides exporters with new opportunities to expand into distant overseas markets. The novelty of this research lies in the use of different storage environments to investigate the senescence mechanisms at tissue level of Dendrobium orchid flowers in response to ACC synthase and ACC oxidase enzyme activity.
