Postharvest life of ‘Palmer’ mangoes stored at 2 and 5°C is reduced to 3 and 6 days, respectively, due to CI, whereas quality of the fruit stored at 15 and 20°C deteriorates after 5 days due to decay, shriveling, and overripe appearance. ‘Tommy Atkins’ postharvest life is reduced to 3 days at 5, 15, or 20°C. 25. scalding. Chilling injury in ‘Palmer’ mango after storage at 2°C plus transfer for 2 days at 20°C. 24. Appearance of ‘Palmer’ mango stored for 15 days at 2°C. After 9 days slight pitting of the skin becomes apparent.

Between 6 and 8°C), however, tends to delay the decrease in acidity and the increase in soluble solids content of ‘Tommy Atkins’ mangoes, independent of the ripening stage of the fruit (Morais and Assis 2004). In ‘Kensington’ mangoes stored at 1°C the total soluble solids content showed a significant decrease between the third and fourth weeks of storage (Chaplin et al. 1991). Fruits with severe CI did not reach the normal soluble solids and citric acid levels after 4 weeks at 0 or 2°C, which were attained by fruits stored at 14 and 20°C (Lederman et al.

Therefore, to minimize loss of moisture and fruit peel dissection, wax coatings are generally applied to the fruit after washing and prior to storage as a standard packinghouse procedure.

Waxing minimized loss of typical orange color and peel glossiness but reduced total phenol content (Moussaid et al. 2004). Temperature also affects the composition of oranges during the postharvest period.
