![]() Observed data showed that the higher chitosan concentrations was used, the higher capability of the sapodilla’s peel to hampered water vapour and oxygen’s to peddix the peel. The parameters observed were the concentrations of chitosan coating thickness on sapodillas’peel, the permeability of chitosan membrane to the air water vapour and oxygen, shelf life, hardness, content of chlorophyll and carotenoid, and respiration of the fruit. ![]() Sapodillas used in this study had the same age in the weight of 100-120 grams and were harvested from the same tree. Collected data were analyzed using analysis of variance (ANOVA) followed by the Duncan’s Multiple Test (DMRT) at the test level of 5%. Each treatment was made in five replicates. Factorial Split-Plot Design was used in this experiment: three levels of storage temperature as the main factors (5 ☌, 15 ☌, 25 ☌) and four levels of chitosan concentrations (0%, 2%, 3%, 4%) as the sub-factors. The objectives of this study were: (1) to examine the effect of chitosan coating concentrations and storage temperature on the physical and chemical characteristics of sapodilla and (2) to determine the chitosan coating concentrations and the optimum storage temperature for the storage of sapodilla. Sapodilla ( Manilkara achras (Mill.) Fosberg) is a climacteric and highly perishable fruit with thin peel.
