Special Issue Information

Dear Colleagues,

Improving crop quality and shelf-life is a challenge in the context of a global horticultural food supply. Horticultural crops are an important source of organic acids, proteins, carbohydrates, vitamins, and minerals for human nutrition and well-being. Fresh horticultural crops are living tissues that undergo constant changes after harvest; since they contain a lot of water, they are susceptible to mechanical damage and weight loss. As perishable goods with an active metabolism, horticultural commodities are subject to significant postharvest losses due to senescence, physical damage, and microbiological deterioration. Postharvest changes in horticultural crops cannot be stopped, but they can be slowed to a certain extent. Maintaining or enhancing fresh horticulture crops' postharvest life is becoming more and more crucial. In fact, sustaining food quality, reducing waste, and expanding food availability depend heavily on proper postharvest management and technology. Because fresh horticultural crops differ in their composition, morphological structure, and general physiology, different commodities have distinct requirements and recommendations for preserving quality and extending postharvest life. The aim of this Special Issue is to highlight and describe recent and advanced research regarding postharvest management and technology that affects (fresh and processed) horticultural products’ quality, physiology, and shelf-life. In this SI, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: postharvest treatments, as well as management and technology that affect (fresh and processed) horticultural product quality, physiology, and shelf-life.

Gum arabic (GA)-based edible coatings enriched with natural bioactive compounds offer a promising strategy for reducing postharvest losses and maintaining fruit quality. This study evaluated the effectiveness of GA coatings supplemented with carvacrol or caffeine in preserving the physicochemical quality, antioxidant status, and marketability of ‘Murcott’ mandarins during cold storage (5 ± 1 °C, 90–95% RH) for 60 days followed by 4 days of shelf life. Fruits were treated with distilled water (control), GA (10%), GA + imazalil (2000 ppm), GA + carvacrol (200 ppm), and GA + caffeine (200 ppm). Key quality parameters, including weight loss, decay incidence, firmness, electrolyte leakage, malondialdehyde (MDA), total soluble solids, titratable acidity, ascorbic acid, total phenolics, total flavonoids, and antioxidant enzyme activities of catalase (CAT) and peroxidase (POX), were evaluated. The results demonstrated that GA-based coatings, particularly GA + carvacrol, significantly reduced weight loss and decay while maintaining firmness and visual quality compared to the control. Coated fruits exhibited lower electrolyte leakage and MDA levels, indicating improved membrane integrity and reduced lipid peroxidation. In addition, the treatments enhanced antioxidant capacity, as reflected by increased phenolic and flavonoid contents and higher CAT and POX activities. Multivariate analysis further confirmed the strong association between coating treatments and improved quality attributes. In conclusion, GA coatings enriched with carvacrol or caffeine effectively improved postharvest quality and extended the shelf life of ‘Murcott’ mandarins, highlighting their potential as safe and eco-friendly alternatives to conventional postharvest treatments.
