Special Issue Information

Dear Colleagues,

Currently, postharvest losses of fruits and vegetables amount to an incredible 30% due to physiological and microbiological diseases caused by inadequate postharvest treatments and storage conditions. In addition to losses, inadequate postharvest treatments also impact fruit and vegetable sensory quality, which might result in an unacceptable produce quality and consequently loss of produce.

The focus of this Special Issue encompasses the following topics:

  • Postharvest application of chemical compounds (aldehydes, higher alcohols, other aroma volatile precursors) to modulate physiology of fruits and vegetables during storage and shelf life;
  • Fruit storage conditions (ultra-low oxygen, dynamic atmosphere) and aroma volatiles;
  • Physicochemical characterization (contact angle, roughness, zeta potential) of fruit cuticles during storage and shelf life;
  • Control of mold growth using alternative treatments (chitosan, etc.); development of edible coatings;
  • Alternative heat treatments of fruit and vegetable in terms of replacing phytopharmaceuticals;
  • Light treatments and postharvest physiology of fruits and vegetables;
  • Electronic nose and maturity stage of fruits during shelf life.

Potential authors are invited to submit original research articles, review articles, opinion papers and short communications.

‘Barhi’ dates (Phoenix dactylifera L.) are highly prized and widely consumed at the khalal stage, but they are only available for a short time, which highlights the importance of extending their storage life. This study examined the effectiveness of edible coatings in delaying ripening and maintaining fruit quality during cold storage (2 °C). The treatments tested were gelatin alone or gelatin combined with chitosan, Aloe vera gel (AVG), or gum arabic, and applied in a layer-by-layer (LbL) approach. A fifth treatment consisting of deionized water was used as a reference untreated control. The fruit parameters measured included weight loss, decay, moisture content, ripening (rutab transformation), firmness, color (lightness and hue angle), total soluble solids (TSS), titratable acidity (TA), TSS/TA ratio, total sugars, total polyphenols, and enzymatic activity. Results indicated that the LbL edible coating was more effective in preserving postharvest quality. Regarding weight loss and decay rate, the results showed that the control treatment consistently had 1.5–5-fold higher deterioration indicators than the coated fruits. Among the tested treatments, the gum arabic and gelatin coating was the most effective compared to the untreated control, reducing weight loss by over 40%, lowering decay by approximately 80%, and maintaining significantly higher moisture content throughout storage. Concerning carotenoid levels, the untreated fruits exhibited approximately 1.2–1.4-fold higher carotenoid content than the coated fruits. Fruits treated with gum arabic and gelatin exhibited the best preservation effect Sby limiting TSS increase and maintaining higher TA compared with the control. This treatment best maintained antioxidant capacity and phenolic content while significantly suppressing the activities of polyphenol oxidase and peroxidase. Overall, the LbL coating strategy successfully maintained the quality of ’Barhi’ dates by mitigating oxidative and enzymatic degradation throughout storage. Principal component analysis and hierarchical cluster analysis demonstrated that treatments gum arabic and gelatin exhibited superior effectiveness in extending the date storage life in terms of physicochemical properties and antioxidant activity, followed by chitosan and gelatin, and Aloe vera and gelatin, compared to the control fruits over a 60-day storage period.
