Abstract
A coating emulsion was prepared using maltodextrins, carboxymethylcellulose, propileneglycol and a mixture of sorbitan fatty acid esters with an HLB of 6. The emulsion was sprayed on fully mature, unripened manila mangoes, which were the stored at 15 and 25 C and 80-85% R.H. At 25 C it was observed that rate CO2 production increased and lost in control fruits after 12 days of storage. Coated mangoes kept their rate CO2 production and suffered only 8% weight loss after 21 days of storage. After storage, the coating was washed out and fruits were allowed to ripen naturally, which occurred in 3-4 days. The results obtained from this study indicate that application of the hydrophobic coating extended the postharvest storage of mangoes for at least 20 days more than uncoated fruits.
