Abstract: Fungal growth in table grape (Vitis vinifera cv. Beauty seedless) triggered by Botrytis cinerea, Penicillium spp., Aspergillus spp., and Rhizopus stolonifera, deteriorates quality during postharvest storage. Sulfur dioxide fumigation or chemical- based antifungal pads that have been employed in grapes may affect consumer health. Considering the safety aspects, this research aimed to develop a hazard-free antifungal packaging embedded with essential oil (EO) to alleviate the fungal decay of table grapes. The various levels of EOs (0. 5- 5% v/v) from clove, cinnamon, thyme, peppermint, lemon, bergamot, ginger, spearmint, and lemongrass were tested against Aspergillus sp. The results attained in radial growth, disk diffusion method, minimal inhibitory concentration, and minimal fungicidal concentration revealed that 1% clove essential oil (CEO) showed higher efficacy against Aspergillus sp., compared to the untreated control and other treatments. CEO at 1% level exhibited pleasant odor intensity in table grapes than the other EOs. Active polyvinyl alcohol (7% PVA) film with 1% CEO resulted in lower weight loss, disease severity, and table grapes berry drop than the control and other treated samples. Additionally, the acceptance score in the table grapes sample wrapped with PVA film containing 1% CEO was augmented. Therefore, PVA film with 1% CEO retarded the fungal growth and prolonged shelf-life of table grapes during storage of 21 days at 13 °C and 75% RH.
