Abstract

Aim: The objective of the present study was to investigate the influence of hexanal formulation on delaying ripening as well as its impact on quality attributes of mango cultivars Banganapalli and Alphosno.?? ?

Methodology: Treatments included 2% hexanal formulation pre-harvest spray at 15^th and 30^th day before harvest,? post-harvest dip for? two minutes, combination of spray and dip and no spray and dip stored at ambient and cold storage condition. ?

Results: The physiological parameters revealed loss in weight, respiration rate, ethylene evolution rate and fruit firmness of fruits subjected to combination of pre-harvest spray and post-harvest dip with hexanal formulation and kept in cold storage were superior as compared to control under ambient storage condition. Treatments with hexanal formulation significantly influenced total sugars, total carotenoids and total flavonoids in the fruits. Ascorbic acid content and total antioxidant activity was enhanced in pre- and post-harvest hexanal formulation treatments as compared to control by 11% and 28%. The effect of hexanal formulation as pre-harvest spray and post-harvest dip extended the shelf life of mango fruits from 5 days to 10 days in ambient storage and from 12 days to 20 days in cold storage.??? ???

Interpretation: Pre and post-harvest hexanal formulation treatments along with cold storage offers significant promise to increase the post-harvest fruit quality and reduce post-harvest losses in mango.
