%X Sapodilla (Manilkara achras (Mill.) Fosberg) is a climacteric and highly perishable fruit with thin peel. 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. Factorial Split-Plot Design was used in this experiment: three levels of storage temperature as the main factors (5 ˇăC, 15 ˇăC, 25 ˇăC) and four levels of chitosan concentrations (0%, 2%, 3%, 4%) as the sub-factors. Each treatment was made in five replicates. Collected data were analyzed using analysis of variance (ANOVA) followed by the DuncanˇŻs Multiple Test (DMRT) at the test level of 5%. Sapodillas used in this study had the same age in the weight of 100-120 grams and were harvested from the same tree. They were observed until rotten. The parameters observed were the concentrations of chitosan coating thickness on sapodillasˇŻpeel, 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. Observed data showed that the higher chitosan concentrations was used, the higher capability of the sapodillaˇŻs peel to hampered water vapour and oxygenˇŻs to peddix the peel. However, the chitosan coating concentration of 4% and the storage temperature of 5 ˇăC temperature made the chitosan layer flaked. The treated concentrations of chitosan coating (0%, 2%, 3%, 4%) at certain storage temperature variations (5 ˇăC, 15 ˇăC, 25 ˇăC) and their interactions had an effect on the physical characters of sapodilla in all parameters. The higher coated chitosan concentration applied, the hardness of sapodilla increased. The chlorophyll contents of sapodilla peel were increasing along with the hampering of the ripening. When the sapodillas were ripe, the carotenoid contents increated. The oxygen contents were decreasing along with the ripening of the sapodillas. The CO2 contents were increasing along with the ripening process of the sapodillas. The optimum treatment to keep sapodillasˇŻ shelf life was the chitosan coating of 3% and the the storage temperature of 5 ˇăC. ABTSRAK Buah sawo (Manilkara achras (Mill.)
