During fruit ripening, the production of reactive oxygen species
(ROS) increased while the antioxidant defense system decreased
. H2O2, an oxidative parameter, significantly
increased in uncoated mango during ripening while lowered in
coated mango (Fig. 5). HM-CTS demonstrated the lowest H2O2
content among all treatments. These results suggested that HMCTS
chitosan coating resulted in a significant reduction in the
H2O2 content of mango fruit during the ripening stage. Chitosan
solution was reported to induce reactive oxygen species scavenging
capacity and to have an increase in phenolic compounds, flavonoid,
and lignin contents in many fruits
