Abstract:
This study was conducted to observe and determine the best post harvest
treatment on mango fruits after treated with chitosan, papain and chitosan-papain
combinations on post harvest quality of mango fruits in the ambient storage by
analyzing the changes in weight loss (%), firmness (g), TSS, peel colour and visual
appearance (defects) on mango fruits. Three different coating formulations were used
which were chitosan (1 %), papain (O.lg/L) and chitosan-papain combinations
(chitosan 0.5% + 0.05g papain/L). However, all of these 3 treatments were not
effective in maintaining the changes in total soluble solid (TSS) content of mango
fruits during the storage time. Mango fruits treated with papain (O.lg/L) showed the
best result in maintaining the visual appearance (defects) compatible with benomyl
(10g/L) treatment. It is suggested that, chitosan (1 %) is the best treatment in delaying
ripening and maintaining firmness of mango fruits, while papain (O. lg/L) are
potentially reducing the defects for mango fruits.
