Composite Coatings Delay Ripening and Maintain Postharvest Quality in Pear Stored Under Cold and Supermarket Conditions

The present study envisages the potential impact of composite coatings of beeswax (BW) and salicylic acid (SA) on enhancing the postharvest storability of pear ( Pyrus spp.) fruits under cold and supermarket storage conditions. The study was conducted during two pear harvest seasons (2019 and 2020),...

Description
Summary:The present study envisages the potential impact of composite coatings of beeswax (BW) and salicylic acid (SA) on enhancing the postharvest storability of pear ( Pyrus spp.) fruits under cold and supermarket storage conditions. The study was conducted during two pear harvest seasons (2019 and 2020), and the data were pooled for the analytical determinations. All fruits with composite BW + SA and single BW coatings, SA treated and untreated fruits were analysed for quality attributes for a period of 67 and 20 days of cold and supermarket storage period, respectively. BW + SA coatings effectively restrained the variations in the biochemical attributes, including soluble solid content (SSC), total sugars, and titratable acidity (TA), throughout the cold and supermarket storage periods. Further, the composite coatings retarded the fruit colour change (∆E) and ripening index (RI), indicating delayed fruit senescence. Under cold storage conditions, BW 2.0% + SA 2.0 mM efficiently enhanced the storage life of pear fruits for 67 days, and under supermarket storage conditions, BW 2.0% + SA 2.0 mM coatings increased storage life up to 20 days, respectively, while maintaining the sensory quality (SQ).
