Abstract: Postharvest quality maintenance is vital for ensuring the marketability and consumer acceptance of perishable crops like papaya. This study investigated the efficacy of in combination of edible coatings with essential oils in enhancing the postharvest quality and reducing disease susceptibility of papaya fruits. The antifungal potential of five essential oils (Basil, cinnamon, clove, pepper mint, and thyme) were evaluated against papaya common postharvest rots causing pathogens viz., Colletotrichum gloeosporioides, Fusarium oxysporum, and Aspergillus niger were through in vivo and in vivo conditions. The studies revealed significant inhibitory effects on mycelial growth, with thyme oil at 1000 ppm concentration. Furthermore, papaya fruits treated with edible coatings and thyme oil at 1000 ppm were subjected to comprehensive analyses over a 10-day period. Results showed significant reductions in physiological weight loss, delayed fruit ripening and decreased disease incidence compared to untreated fruits. The impact of the treatments on overall fruit quality attributes viz., total soluble solids (TSS), vitamin C content, titrable acidity, and Beta- carotene levels were also evaluated. These findings highlighted the potential of utilizing green technology approaches, such as edible coatings and essential oils, to enhance the postharvest quality and extend the shelf life of papaya fruits, thereby contributing to sustainable agricultural practices and meeting consumer demand for high-quality, healthy produce.
