Abstract
The changes in physico-chemical compositions after postharvest ripening of mango fruit can
effectively inhibit with 1-methylcyclopropene (1-MCP) application, chitosan coating and modified
atmosphere packaging (MAP) under low temperature storage. ‘Irwin’ mango fruit were treated
with 5 µL L
-1
1-MCP for 12 h, dipped with 0.5% chitosan coating, packed in polyethylene (PE)
bags and untreated (control) thereafter stored at 10oC. Application of 1-MCP delayed firmness
loss, titratable acidity (TA), inhibited increase of electrolyte leakage (EL) during storage.
Moreover, 1-MCP prolonged storage life of mango for 32 days which was a 5 day extension or
19% when compared with the control. The PE bags treatment reduced weight loss in comparison
with other treatments. Both 1-MCP and chitosan treatments delayed the increase of pH and all
treatments reduced fruit decay. In addition, 10°C did lead to chilling injury (CI) symptoms in
mango in any of the treatments. Therefore, 1-MCP application can inhibit ripening, maintain
physico-chemical compositions, postharvest qualityand prolong the storage life of mango during
storage low temperature condition in order to expand marketability and the potential for export.
