After that the fruits were stored in the cold room, were picked at two maturity stage (matured stage and ripened stage) the fruits were divided to five groups each group with 3 replicates. The studied factors were as follow Maturity stages (Maturation stage, ripening stage) and Coating treatments with two chitosan concentration (Chitosan 1%, Chitosan 2%) and Perforated polyethylene packaging Imperforated polyethylene packaging the result shoed that Coating with chitosan 2% and ripening stage significant increase differs in parameter ( Total soluble solids (TSS %), Titratable acidity (%), Total sugar (TS %), Total soluble solids /acid ratio (TSS/TA), Fruit weight loss (%), Fruit firmness (kg.cm2), Vitamin C (mg.100 mL-1 juice), Peel carotene content (mg.100 mL-1), Decayed fruits percent Data were tabulated and statistically analyzed with the computer using SAS program. The differences between various treatment means were tested with Duncan Multiple Range test at 0.05 levels [1].
