“…The graphs show various patterns of RH readings obtained from the two chambers. The points with an RH over 100% reflect supersaturation, which occurs when water is present in the form of tiny droplets (Rodov et al, 2010). More readings with an RH over 100% were observed in the ultrasonic chamber than in the nanomist chamber.…”

“…The reduction in water potential is important because the flow of liquid and/or gaseous water out of a produce, tissue or plant cell, as well as the rate of water movement directly depends on the water potential gradient between the produce, tissue, or plant cell and the surroundings (Gomez Galindo, Herppich, Gekas, & Sjoholm, 2004: Nobel, 2009). Water potential can be defined as the free energy of water within the respective system, such as produce, tissue, plant cell, or solution compared to that of pure water (Rodov et al, 2010). Thus, water potential is indicative of the true water deficit of a system (Herppich, Mempel, & Geyer, 1999).…”

“…For most FFV the storage conditions should be within 85% and 98% RH. Nonetheless, for products such as garlic and onion storage at RH higher than 70 to 75% at optimum temperatures results in excessive water absorption leading to rooting, mould development and sprouting (Rodov, Ben-Yehoshua, Aharoni, & Cohen, 2010). In the review by Paull (1999) the possible effects of temperature and RH on fresh commodity quality was extensively discussed.…”

Transpiration has various adverse effects on postharvest quality and the shelf-life of fresh fruit and vegetables (FFV). If not controlled, the water released through this process results in direct mass loss and moisture condensation inside packaged FFV. Condensation represents a threat to the product quality as water may accumulate on the product surface and/or packaging system, causing defects in external appearance and promoting growth of spoilage microorganisms. Thus, moisture regulation is extremely important for extending FFV shelflife. This review focuses on transpiration phenomenon and moisture evolution in packaged fresh horticultural produce. It provides recent information on various moisture control strategies suitable for packaging of fresh horticultural produce. It also provides an evaluation on the role and application of integrative mathematical modelling in describing water relations of FFV for packaging design, as well as, an overview of models reported in literature.

BACKGROUNDFluctuations in environmental conditions within fields and crop plant performance can greatly affect production and quality standards. These factors are particularly relevant for producers, who require sustained optimal production to profit from small margins. Fluctuations might be exacerbated at the end of the crop season, where neither of the aforementioned factors are optimal. In the present integrated study, we assess strawberries' nutritional quality and the impact of harvest timing, tunnel conditions and inter‐individual variability in a Mediterranean production tunnel divided into blocks, where two harvests were performed 3 weeks apart. In addition, the effects of sprayed melatonin at the end of productive season were also evaluated.RESULTSEnd‐season harvesting negatively impacted fruit hydration, antioxidant capacity and ripening‐related hormones in strawberry fruits. Additionally, tunnel distribution influenced fruit nutritional quality, with light radiation being the main variable factor disturbing antioxidant contents. Nutrients exhibited high inter‐individual plant variability, accounting for 20% variation, and were strongly correlated with fruit hydration and ripening‐related phytohormones. Finally, melatonin applications affected neither fruit production, nor nutritional parameters, for which the effects were masked by the intrinsic strawberry variability. Overall, the results underline the limitations of this type of application for field implementation.CONCLUSIONFruit quality variation in strawberry fields is explained by environmental and inter‐individual variability. Likewise, the implementation of regulatory molecules such as melatonin in field applications relies on crop homogeneity and might have limited applicability in heterogeneous productive systems. Consequently, identifying and reducing microclimate variability in productive fields is paramount for advancing agricultural practices to uphold unwavering standards on fruit quality. © 2024 The Author(s).
