Mango is a significant global fruit crop, producing over 1,000 million tonnes annually. However, postharvest losses due to pathogenic fungal infections are considerable, exacerbated by the continuous use of synthetic fungicides, which pose risks of fungal resistance and environmental harm. This study assessed the effectiveness of Origanum vulgare-based nanoemulsion against mango postharvest diseases and quality preservation. Results indicate that the O. vulgare nanoemulsion (Ore-S1-15) exhibited optimal properties, including small droplet size, low polydispersity, and stable pH. FTIR analysis identified key functional groups, while GC-MS results revealed prominent components with isopropyl myristate being the major constituent at 42.41%, followed by isopropyl palmitate (25.53%), oleic acid (4.57%), diethyl phthalate (3.84%), estagole (2.09%), 2-(phenylmethylene)-octanal (1.17%), cyclopentane acetic acid (0.85%), benzoic acid (0.34%), and coumarin (0.26%) as minor constituents. In vitro test of the Ore-S1-15 nanoemulsion against Curvularia sp. demonstrated significant antifungal activity, with 79.51 ± 0.95% conidia inhibition. Additionally, in vivo test showed a reduction in disease incidence on wounded mangoes. The Ore-S1-15 nanoemulsion enhanced quality parameters by delaying colour changes, reducing weight loss and steadily maintaining the total soluble solids. Thus, Ore-S1-15 nanoemulsion emerges as a promising and eco-friendly alternative to synthetic fungicides for controlling mango postharvest diseases and increasing shelf life while preserving quality.

Challenges of postharvest water loss in fruits: Mechanisms, influencing factors, and effective control strategies – A comprehensive review

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.
