Slow Release of Hexanal By Biodegradable Electrospun Nanofibres for Increasing Shelf-Life of Harvested Mango Fruits

Abstract

Phospholipase D (PLD) is a crucial enzyme indeterioration of membrane phospholipid by a cascade of metabolic reaction which can be effectively inhibited by hexanal, a C6 aldehyde (volatile) naturally produced asplant defense mechanism. In this study, hexanal is encapsulated by PVA nanofibre intercalated with nanocellulose using electrospinning. In ourstudy, nanocellulose was prepared using biodegradable wastes from banana pseudostem of Grand naine and Poovan cultivars through acid hydrolysis method to increase the loading capacity of matrix. anocellulose extracted from Grand naine and Poovan varieties were found to be 15-25 nm respectively.Further, the prepared matrices were loaded with hexanal in both passive and active method. The effect of hexanal loaded nanofibre on mango fruits in extending shelf life was studied. The actively loaded matrix showed slower and uniform release of hexanal inside the packaging box, while passively loaded matrix initially exhibited burst release pattern, followed by a decrease in the hexanal release pattern. Fruit ripeness parameters such as physiological loss in weight (PLW), vitamin C content, total soluble solids (TSS) and change in fruit colour were positively correlated with the hexanal release pattern till 11 days of storage period at room temperature.These findings give an opportunity to explore electrospinning and encapsulation of various volatile compound for slow release application in post-harvest studies of perishables
