The objective of this study was to evaluate the effect of pressurization on the concentration of some antioxidant compounds and the antiradical efficiency during the ripening process of 'Ataulfo' mango. The fruits at physiological maturity stage were pressurized at 15, 30, or 60 MPa for 10 or 20 min. Control fruits were not pressurized. The fruits were stored at 25 degrees C and changes in the concentration of ascorbic acid, total phenols, total flavonoids, total carotenoids, and antiradical efficiency were evaluated. It was demonstrated that in 'Ataulfo' mango high hydrostatic pressure treatments at 60 and 30 MPa for 20 minutes induced the synthesis of ascorbic acid during storage maybe as a consequence of physiological changes and possible structural modification of the cells, while the fruits pressurized at 15 MPa showed no effect on this parameter. On the other hand, the use of 15 MPa for 10 minutes increased the synthesis of phenols, flavonoids, carotenoids, and antiradical efficiency in 'Ataulfo' mango compared to that of the control fruit. In conclusion, this behavior seemed to be due to the low hydrostatic pressure treatments (15 Mpa), which stimulated the synthesis of antioxidants in the mango fruit and ripening was not inhibited.
