    Hydrophobic deep eutectic oil (menthol-thymol)-in-water nanoemulsion was developed to preserve the quality of banana fruit and extend their storage shelf life. Storage preservation of bananas presents several challenges due to their high respiration rate, ethylene production, and susceptibility to various physiological and biochemical changes. The storage shelf life of bananas is relatively short compared to other fruits due to the combination of rapid ripening and sensitivity to ethylene and temperature. In this study, the effectiveness of HyDEN treatment was assessed on changes in banana fruit’s physiological parameters such as firmness, weight loss, total soluble solids, titratable acidity, and colour for 14 days storage time [25 Â°C ± 1 Â°C, 67% relative humidity (RH)]. HyDEN treatment preserved the physicochemical characteristics of banana fruit and was effective in delaying the ripening process. The storage shelf life of banana fruit treated with HyDEN increased for 14 days compared to control that ripened and physically damaged after 8 days of storage. This study provided a new delivery system for applying HyDEN as an edible coating to fruit after harvest preservation.

    Water loss is a critical concern in postharvest fruit technology, significantly impacting fruit quality, shelf life, and market value. This phenomenon involves the loss of moisture from fruit tissues, leading to physiological changes, reduced quality, and lower market value, which can contribute to food waste. Consumers perceive fruit with visible signs of water loss as lower quality. Therefore, minimizing water loss is essential through proper postharvest handling and storage practices, including temperature and humidity control, cooling, humidification, and the application of edible coatings and new modified coating techniques. Despite the importance of managing water loss, comprehensive information on its mechanisms and contributing factors in postharvest fruit technology is scarce. This paper aims to provide insights into the mechanisms, impact, influencing factors, and control strategies related to water loss in the context of postharvest fruit technology.

    Hydrophobic deep eutectic nanoemulsions derived from fatty acids and terpenes (referred to as HyDEN) were introduced as potential nano-coating to effectively combat anthracnose during the postharvest preservation of fruits. Anthracnose primarily caused by the Colletotrichum gloeosporioides species is known for causing substantial damage to fruits. Synthetic fungicides have proven to be effective but come with environmental, health, and safety concerns. In this study, hydrophobic deep eutectic solvents (HDESs) were evaluated for their physical properties to identify the most suitable HDES for the formulation of HyDEN. Menthol-Thymol (MT) at 1:1 and 2:1 ratio met the criteria and was chosen for the formulation of HyDEN. HyDEN (MT-N 1:1) displayed a higher zeta potential value and smaller mean droplet diameter and then tested for its antifungal properties against C. gloeosporioides compared with selected antifungal agents. HyDEN (MT-N 1:1) exhibited strong antifungal activity against C. gloeosporioides and was attributed to its potent mode of action, binding affinity, and rapid onset compared to HDES and fungicide (Globus 5.5). This study also investigated how HyDEN (MT-N 1:1) affects mycelial growth, cell membrane permeability, and cellular leakage of C. gloeosporioides, highlighting its superior disruption of cell membranes compared to HDES and Globus 5.5. This research presents an eco-friendly alternative to the use of toxic chemicals and showcases an innovative and sustainable approach to controlling anthracnose in postharvest fruit preservation.

    A hydrophobic deep eutectic oil-in-water nanoemulsion (HyDEN) was developed as a potential edible coating for preserving 'Harumanis' mango. Preventing water loss in mango during postharvest handling and storage is crucial to maintain their quality and market value. Mango with high respiration rates during storage tend to have shorter shelf life due to issues like softening and over-ripening. Edible coating materials such as lipids, polysaccharides, and proteins have setbacks such as poor water vapor barrier and potential contamination which affect their performance in preserving fruit quality. In this study, a HyDEN coating was prepared to preserve 'Harumanis' mango. The HyDEN coating exhibited good stability, with a high zeta potential value of −42.02 ± 0.12 mV, a robust antioxidant property of 97.89 ± 0.14%, and relatively low mean droplet sizes averaging 210.04 ± 0.89 nm. The application of HyDEN coating effectively extended the shelf life of 'Harumanis' mango. Additionally, it slowed down the ripening process, preserving the fruit's quality in terms of weight loss, firmness, total soluble solids, colour, titratable acidity, pH, radical scavenging rate, browning index, total phenolic content, total flavonoid content and sensory attributes after 20 days of storage, whereas the control fruit began to overripe and deteriorate after 10 days. This study introduces a novel delivery system for applying HyDEN as an edible coating for postharvest fruit preservation.
