AI Article Synopsis
- The increasing demand for fruit safety and environmental protection has led to the exploration of plant essential oils, particularly oregano essential oil (OEO), as natural alternatives for controlling postharvest decay in fruits.
- In this study, OEO demonstrated powerful antifungal effects against postharvest pathogens, maintaining quality attributes of pears while inhibiting fungal growth through disruption of plasma membrane integrity.
- The findings indicate that OEO not only reduced weight loss and preserved firmness in pears but also enhanced their antioxidant capacity, suggesting its potential as a sustainable alternative to synthetic fungicides in postharvest management.
Article Abstract
Given the increasing demand for fruit safety assurance and environmental protection, plant essential oils have gained significant attention as natural alternatives for control of postharvest decay caused by various pathogens. In postharvest management, it is particularly important to effectively control postharvest decay without compromising the quality attributes of fruits. Although oregano essential oil (OEO) has been extensively studied for its antimicrobial properties against various postharvest pathogens, few studies have focused on its interactions with postharvest fruits. In this study, OEO was applied for management of postharvest decay of caused by , and its antifungal mechanisms and impacts on the quality attributes of pears were investigated. The OEO exhibited notable inhibitory effects, with determined MIC (0.02%) and MFC (0.04%) against , which highlighted its potential as a viable alternative to synthetic fungicides. Our findings revealed that OEO disrupted by compromising the integrity of the fungal plasma membrane, as evidenced by changes in plasma membrane permeability and the leakage of cellular components. The OEO treatment significantly reduced weight loss, maintained firmness, and preserved soluble-solid content in the treated pears. In addition, OEO treatment stimulated the intrinsic antioxidant mechanisms of pears, as demonstrated by elevated activities of superoxide dismutase and catalase during storage. This study provides compelling evidence for the antifungal and quality-preserving properties of OEO in the postharvest management of pears, underscoring its potential as an alternative to synthetic fungicides for controlling postharvest decay. The elucidation of the interaction between OEO and would greatly enhance our comprehensive understanding of the biological activities of OEO and facilitate its practical application in the postharvest management of pears.

This study investigates the effect of 100 mg L thymol treatment on the quality of post-harvest peppers stored at 10 °C. The results showed that thymol treatment significantly reduced decay rate, reactive oxygen species (ROS) accumulation, and saturated fatty acid levels in peppers. Moreover, unsaturated fatty acids, non-enzymatic antioxidants, and antioxidant enzyme levels increased after treatment.

Significant losses of vegetables and fruits occur at multiple stages, including harvest, sorting, storage, and transportation, primarily due to mechanical damage, pathogen invasion, and the natural process of senescence. To mitigate postharvest decay and maintain superior quality of produce, conventional techniques such as low temperature storage and synthetic fungicide treatment are widely employed. Acibenzolar-S-methyl (ASM), an effective plant resistance inducers, has demonstrated its efficacy in protecting against a diverse range of fungal and bacterial pathogens.

Although postharvest partial dehydration has been applied to enhance blueberry wine flavor by increasing terpene level, berry decay remains a concern. Melatonin is known to improve fruit resistance during storage, but its role in terpene accumulation in blueberries during postharvest dehydration remains unclear. This study identified aroma-active terpenes of blueberry wines applying aroma extract dilution analysis and revealed the key genes linked to the increased terpenes in dehydrated blueberries.
