Refrigerated containers are essential for protecting fruit during shipment by managing the environmental conditions that influence postharvest longevity and quality. These containers utilize individually motor-driven refrigeration units to maintain specific temperatures, which is critical because the rate of chemical change and enzymatic processes in fruit—which lead to ripening and eventual spoilage—are significantly controlled by ambient temperature.123

Beyond simple cooling, many of these containers incorporate controlled atmosphere (CA) technology. By regulating the levels of oxygen and carbon dioxide within the sealed environment, these systems retard senescence and slow the ripening process. Furthermore, these containers help in the removal of ethylene gas, a substance that naturally emanates from fruits and accelerates ripening. By combining temperature control with modified atmospheres, these containers reduce the need for excessive handling and ensure that produce reaches its destination in better condition.124
