How do refrigerated containers help protect fruit during shipping?

Refrigerated containers are essential for protecting fruit during transit by managing the environmental conditions that influence postharvest longevity. These large, motor-driven units allow growers to maintain precise temperatures, which is critical because the rate of chemical change and enzymatic processes in fruit typically doubles for every 10 °C increase in temperature. By keeping the fruit at a level best suited to its specific needs, refrigeration effectively slows the ripening process and retards senescence.123

Many of these containers also utilize controlled atmosphere (CA) technology, which adjusts the levels of oxygen and carbon dioxide within the sealed environment. By reducing oxygen and increasing carbon dioxide, suppliers can further inhibit respiration and deterioration. Additionally, these systems often work in conjunction with the removal of ethylene gas—a substance emitted by fruits that accelerates ripening—to ensure the produce arrives in better condition. This integrated approach reduces the need for manual handling and helps maintain the quality of highly perishable commodities during long-distance shipping.324
