| Abstract:
Mexican mango exports represents approximately 115,000 MT per year. They are transported in refrigerated containers and occasionally in controlled atmospheres. However, reports on the keeping ability of controlled atmospheres upon mango are controversial. The objective of this study was to evaluate the storage life of ‘Kent’ mangoes at 13°C in air and in two controlled atmosphere conditions, 5% CO2-5% O2 and 10% CO2-5% O2. Mature ‘Kent’ mangoes produced in Mexico (22°20' N;105°30' W) were stored in the three atmospheres described above, applied in the Universidad Autonoma Metropolitana Iztapalapa. The response variables included: %SSC, titrable acidity, flesh firmness and colour, physiological weight loss, respiratory activity and histological changes. In addition, sensory evaluation was carried out. The data were collected during a total of 25 days of storage. Once the storage time under atmospheres was concluded, samples were withdrawn from the storage conditions and placed for another 5 days at 25°C in air. The response variables were also recorded during this period. Analysis of variance ( | |

=0.05) gave no significant differences among treatments for SSC, titrable acidity, flesh firmness, flesh colour and physiological weight loss.
However after 21 days storage, sensory tests indicated off-odours and off-flavours in samples stored in controlled atmospheres.
It can be concluded that controlled atmospheres did not have any benefit as compared to refrigeration in extending the storage life of ‘Kent’ mangoes.
