Effect of post harvest treatments on physico-chemical characters during storage of mango cv. Totapuri.

The quality of mango fruits dipped in wax emulsion (4, 6, and 8%), calcium chloride (0.5, 1.0, and 1.5%), and maleic hydrazide (500, 1000, and 1500 ppm) for 2 minutes then packed in perforated polyethylene bags before storage under ambient or cool temperature was studied. Fruit spoilage increased with storage, with the highest incidence observed after 10 days. Fruits treated with 8% wax emulsion had the lowest spoilage incidence. The total soluble solid content (TSS) increased during storage; the increase rate was fastest in the control and calcium chloride (1%)-treated fruits but was delayed in wax emulsion (8%)-treated fruits. The ascorbic acid content decreased with storage. Calcium chloride (1%) and wax emulsion (8%) were most effective in reducing ascorbic acid loss. The lower TSS and higher ascorbic acid contents in fruits under cool chamber storage could be attributed to the prevailing low temperature and high relative humidity.
