(Sanchez-Moreno, Larrauri, & Saura-Calixto, 1998). The
parameter EC50, which reflects 50% depletion of DPPHd
free-radical, was expressed in terms of grams of mango
dietary fibre equivalent per gram of DPPHd in the reaction
medium. The time necessary to reach the steady state at
EC50 (TEC50) was calculated. The antiradical efficiency
(AE), an index defined by Sanchez-Moreno et al. (1998)
which combines both factors, was also calculated in order
to recognize the combined effect of both parameters:
AE ¼ 1/EC50TEC50.
