Abstract

  The experiment was conducted to assess the postharvest quality and storage life of Sein Ta Lone mango affected by wrapping materials and storage temperature. It was carried out at the Laboratory of Department of Horticulture, Yezin Agricultural University during the mango harvest season of May 2018. Treatments were laid out in factorial arrangement, randomized complete block design with four replications. Factor A was the storage at controlled temperature (13˚C) and at room temperature (35 - 38˚C) and factor B was wrapping materials of white net sack, white fruit wrapping paper and without wrapping (control). Sein Ta Lone mangoes were collected from Myanadi mango orchard, Department of Agriculture, Myittha Township, Mandalay Region. The data on physiological weight loss (%), color index, fruit firmness (kgcm^-2), total soluble solid (TSS%), total titratable acidity (TTA%), respiration rate (mg CO₂ kg^-1h^-1), ethylene production rate (µl kg^-1h^-1) and shelf-life (days) were collected at two days intervals throughout the experiment. Control fruits stored at 13˚C significantly showed the longer shelf-life (14 days) than those under room temperature (7 days). The fruits wrapped with paper showed the longest shelf life of 16 days at 13˚C while the fruits wrapped with net sack maintained the longest shelf-life of 8 days at room temperature. The ethylene production and respiration rates of Sein Ta Lone mango under 13˚C were considerably lower than those of the fruits under room temperature but not significantly different among the treatments. The minimum respiration and ethylene production rate of unwrapped mangoes were 10.84 CO₂ mg kg^-1h^-1 and 0.07ul kg^-1h^-1, respectively. The color value rapidly increased in all treatments stored at room temperature at 4 days after storage. However, the color development of the fruits stored at 13˚C gradually increased with lower value than that of those under room temperature. There were no significant differences in TTA% and TSS% among the treatments at respective temperatures. The results from this study revealed that net sack wrapping should be used at room temperature to protect injury and paper wrapping should be used in low temperature storage of 13˚C to absorb moisture and maintain fruit quality.
