The use of both calcium chloride 3% and gum arabic 10%
treatments showed an improvement in ‘Choke Anan’ mangoes
storability at 6 C, a temperature which otherwise leads to
oxidative damage and reduction in quality. Gum arabic 10%
combined with calcium chloride 3% reduced CI, electrolyte leakage,
MDA, H2O2, O2
and maintained high DPPH radical scavenging
activity of mango fruit during low temperature storage. Gum arabic
either alone or in combination with calcium chloride, effectively
inhibited the loss of phenolics and ascorbic acid. The result of
transmission electron microscope showed that treated fruit
maintained cell membrane integrity. Treated fruit showed an
enhanced antioxidant defense system, thereby reducing oxidative
damage and postharvest deterioration of mangoes during storage.The results of the present experiment suggest that the combined
application of calcium chloride and gum arabic might be a simple
and effective technique for maintaining mango fruit quality.
However, further studies are necessary to investigate the possible
mechanism of calcium chloride and gum arabic action in
scavenging the reactive oxygen specie
