Fig. 1 shows different sensitivities of strains to different coatings applied on the mangoes.
The concentration of chitosan in the coating solution and the presence of the enzyme system affected the fungal decay of the fruit.
The percentage of strain inhibition was improved with the increase of chitosan concentration, and it became higher when the LPOS system was added.
The inhibitory action of chitosan alone has already been demonstrated in several studies.
These studies reported that the antifungal effect of chitosan was dependent on concentration (El Ghaouth et al., 1992; Jiang and Li, 2001; Liu et al., 2007).
Chitosan with its positive charges interacts with negatively charged membranes of the cell to alter cell permeability.
