    Inhibition of Aspergillus flavus by Momordica charantia Ethanolic Leaves Extract for Mushroom Protection
    Pleurotus ostreatus, better known as oyster mushroom is one of the world’s widely cultivated mushroom. Infection from pathogenic fungi is one of the major reasons causing losses of mushroom during cultivation. The objective of this study is to investigate the antifungal property of Momordica charantia leaves extract against Aspergillus flavus for mushroom protection. The inhibitory effect of M. charantia leaves extract against A. flavus isolated from infected P. ostreatus mushroom bag was investigated using pour plate technique. Inhibition of A. flavus mycelial growth was the highest at extract concentration of 9.64 v/v %, temperature 26℃ and incubation time of 96 hours with inhibitory value of 70.58 ± 0.00 %, 78.4 ± 0.00 % and 63.33 ± 2.89 % respectively. Structural morphology of the mycelia grown on the treated plate also showed morphological alteration compared to the control plate. Hence, Momordica charantia leaves extract may serves as a promising fungicides alternative to chemical use for controlling invasion of A. flavus on oyster mushroom.

    Investigating the impact of hydrophobic deep eutectic oil-in-water nanoemulsion on cell membrane degradation and inhibition of C.gloeosporioides in postharvest technology
    This study examines the effects of a hydrophobic deep eutectic oil-in-water nanoemulsion (HyDEN) on the cell membrane degradation and inhibition of Colletotrichum gloeosporioides. By analyzing post-treatment cell membrane morphology, we gain insights into the efficacy and mechanisms of action of antifungal agents. Significant changes such as disruption, collapse, wrinkling, and lysis were observed in the external morphology of C. gloeosporioides treated with HyDEN. When comparing control and treatment groups, HyDEN demonstrated more pronounced disruption and greater mycelial growth inhibition than Globus 5.5. HyDEN also effectively inhibited spore germination compared to Globus 5.5. Tests on intracellular ion leakage showed that HyDEN caused higher conductivity, indicating significant membrane disruption. Additionally, HyDEN led to a greater release of soluble sugars due to membrane damage compared to Globus 5.5. These findings suggest that HyDEN is a promising antifungal strategy, effectively disrupting cell wall and membrane functionality, and inhibiting fungal growth.

    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.
