Fruit firmness decreased during the 12-day storage
period. During storage of mango fruits pH values ranged
from 3.5 to 4.5. The highest pH value of 4.5 was
obtained in fruits treated with 300 ml/L of ethanol at 45
oand 50 C. Control fruit showed a pH value of 4.2 at the
end of the storage period. Likewise the collective application of ethanol and heat to control pathogenic
microorganisms has been well documented in temperate
fruits such as table grapes, lemons, peaches and
nectarines.
