PACHECO, ANÁLIA LÚCIA VIEIRA et al. PHYSICAL-CHEMICAL QUALITY OF MANGO ‘Ubá’ (Mangifera indica L.) FRUITS SUBMITTED TO IMPACT MECHANICAL DAMAGE AT HARVEST. Rev. Bras. Frutic. [online]. 2017, vol.39, n.2, e-939.  Epub 05-Jun-2017. ISSN 0100-2945.  http://dx.doi.org/10.1590/0100-29452017939.

The objective of this study was to evaluate the quality of ‘Ubá’ mango fruit submitted to mechanical damage. The fruits were harvested in the 2012/2013 harvest, and let to drop once on a flat, hard surface, simulating the harvesting process of ‘Ubá’ mango, which is to drop all the fruits of a plant when they are physiologically mature. Treatments consisted of different drop heights (zero, one, two, three, four and five meters), totaling six treatments. After the fall, the fruits were submitted to ripening, and then evaluated for fresh mass loss (FML), presence of external lesions (PEL), presence of internal lesions (PIL), soluble solids content (SS),titratable acidity (TA), pH, SS/TA ratio and vitamin C. There was no difference between fresh weight loss of the dropped fruits and control. Regarding the presence of external and internal lesions, damage in fruits due to drop height tends to increase. The fruits that were not dropped presented higher SS content than the others, while those that fell from a height of 5 m had the vitamin C content reduced by 27.78% compared to control. The decrease in SS content and vitamin C was influenced by damage caused by the impact. It is concluded that mechanical damage caused by the impact interferes in the main attributes of quality of fruits and pulp of “Ubá” mango.
