The optimum treatment to keep sapodillas’ shelf life was the chitosan coating of 3% and the the storage temperature of 5 ☌.īuah sawo ( Manilkara achras (Mill.) Fosberg) merupakan buah klimaterik yang mempunyai kulit tipis dan cepat matang. The CO 2 contents were increasing along with the ripening process of the sapodillas. The oxygen contents were decreasing along with the ripening of the sapodillas. When the sapodillas were ripe, the carotenoid contents increated. The chlorophyll contents of sapodilla peel were increasing along with the hampering of the ripening. The higher coated chitosan concentration applied, the hardness of sapodilla increased. The treated concentrations of chitosan coating (0%, 2%, 3%, 4%) at certain storage temperature variations (5 ☌, 15 ☌, 25 ☌) and their interactions had an effect on the physical characters of sapodilla in all parameters. However, the chitosan coating concentration of 4% and the storage temperature of 5 ☌ temperature made the chitosan layer flaked. 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.
