“…This potential could also be confirmed in the same study for 'Galaxy' apples, as lower pO 2 of 0.4 kPa allowed to raise storage temperatures by 0.5 • C without adverse consequences for fruit conservation. Furthermore, this was also associated with lower mealiness symptoms and ethylene production [47].…”

“…This could be confirmed in a later study, which showed that 'Galaxy' apples can be stored at 2.5 • C in DCA-RQ, and compared to 1.5 • C, they showed higher firmness and reduced mealiness incidences [46]. Ludwig et al proposed a similar potential for 'Royal Gala' apples, arguing that by lowering the pO 2 in the storage atmosphere from 1.2 to 0.8 kPa, temperatures can be increased by 0.5 • C [47]. The combination of higher temperatures and extremely low oxygen levels resulted in higher flesh firmness and total soluble solids and reduced flesh breakdown and mealiness incidences.…”

“…Higher firmness, higher TSS, and higher TA [26,28,29,31,35,36,41,43,44] Lower mass loss [28,29,31,35] Higher scores in sensory consumer panels (texture, taste, and buying preference) [28,29,31] Reduced chilling injuries, flesh breakdown, core breakdown, water core, cavities, and mealiness [26,34,35,40,[43][44][45][46][47]] Reduced rot incidences [31][32][33]48] Increased abundance of volatile organic compounds [38] 1-MCP application may subsequently also render the fruit less sensitive to possible temperature variations in the post-storage sector, and maintaining the cool chain may consequently be of lower importance. So far, no studies on apples have tested under practical conditions whether 1-MCP applications pre-storage can directly translate to energy savings in the post-storage and marketing sectors.…”

Storing apples for up to a year is a well-established practice aimed at providing a continuous, locally produced fruit supply to consumers and adapting to market trends for optimized profits. Temperature control is the cornerstone of postharvest conservation, and apples are typically kept at temperatures ranging from 0 to 3 °C. However, the energy-intensive process of the initial cool-down and subsequent temperature maintenance poses significant financial challenges with adverse effects on the carbon footprint. Higher storage temperatures could reduce cooling-related energy usage but also pose the risk of enhanced ripening and quality loss. This work explores different storage technologies aiming to reduce energy consumption, such as 1-methylcyclopropene, ultra-low oxygen, and a dynamically controlled atmosphere with raised temperatures. The integration of advanced monitoring and control systems, coupled with data analytics and energy management, in apple storage is also discussed. These strategies can be implemented without cost-intensive construction measures in standard storage facilities. Furthermore, beneficial side effects of higher storage temperatures in terms of a reduced occurrence of storage disorder symptoms and higher maintenance of quality attributes are also discussed for this special issue on sustainable horticultural production systems and supply chains.

An exploration of the range of expert opinions on the optimum storage temperature for apples and pears in RA (refrigerated air), CA (controlled atmosphere), and DCA (dynamic controlled atmosphere) is provided, based on the accumulated postharvest data from the last 20 years. Apple cultivars have been divided into two storage temperature groups (0 to 1 °C and >1 °C), based on chilling sensitivity. Increasingly, gradual cooling, rather than rapid cooling, is recommended for apple cultivars, especially for chilling-sensitive cultivars. European pear cultivars are held at storage temperatures close to or just below 0 °C since they are not chilling-sensitive, and most cultivars require a cold temperature to induce ethylene production and ripening, especially if picked early for long-term storage. Asian pears apparently have higher temperature requirements in CA, compared with European pears. The temperature recommendations for RA and CA storage differ in some apple and European pear cultivars. In such cases, the CA recommendation is, on average, approximately 0.9 °C higher for apple cultivars and approximately 0.5 °C higher for pear cultivars, compared with RA. Research evidence suggests that some apple and pear cultivars can be stored at higher temperatures in DCA than in CA, and if the ethylene inhibitor, 1-methylcyclopropene (1-MCP), is applied in CA and/or DCA, leading to possible energy savings and quality benefits. A cool growing season may increase postharvest disorders, depending on cultivar and region. The store or packinghouse manager may choose to mitigate potential postharvest problems by maintaining the storage temperature at or above the temperature listed here and/or using stepwise (gradual) cooling. The storage temperature can affect the humidity and vapour pressure deficit (driving force) in the storage room. Altering the vapour pressure deficit controls the water loss in stored fruit, which can affect various quality parameters and the occurrence of several storage disorders.
