among treatments for the parameters evaluated. Fruit firmness also
decreased during the 12-day storage period (Fig. 3A). Firmness
values of peel ranged from 132 N (initial storage) to 88 N (12 days
storage) whilst values of the flesh were of 94 Ne56.8 N. With
respect to the color variable (Fig. 3B), in all treatments color
development was similar including the control. Skin fruit color
developed from lightly red with green tonalities (1) to red and
yellow (4) and the fruit flesh color developed from cream (1) toorange with yellow tonalities. The content of citric acid of the
treated and non-treated fruits systematically decreased during
storage time (Fig. 4A). The average percentage values at the initial
storage time were from 0.5% to 1.0% and after the 12-day storage
period, they were 0.1% in all treatments. During storage of mango
fruits pH values ranged from 3.5 to 4.5 (Fig. 4B). The highest pH
value of 4.5 was obtained in fruits treated with 300 ml/L of ethanol
at 45 and 50 C. Control fruit showed a pH value of 4.2 at the end of
the storage period. The content of SSC also increased during storage
time (Fig. 4C). Overall, the increment in the percentage of SSC was
approximately 7% during the complete storage period. The final SSC
value was 16.0% for most treatments. Fruit weight loss of mango
fruits consistently increased during storage time (Fig. 4D). At the
last storage time of 12 days, percentage weight loss was up to 8.6%
for all treatments.
