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 (0.1g/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 (0.1g/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 (0.1g/L) are potentially reducing the defects for mango fruits.
