3.2.3. FRAP method
The values obtained by FRAP assay were lower than those obtained
by ABTS or DPPH methods but the pattern was similar
(Fig. 2c). FRAP values varied from 41 to 81 m mol TE/g db for thedried mango powder. Drying techniques were shown to have a
significant impact on FRAP values of powders (p 0.05). Soong and
Barlow (2004) reported mango cubes had antioxidant activity of
36.6 m mol/g db, ascorbic acid equivalent, using FRAP assay. Mango
pulp from green and ripe fruit showed FRAP value of 16.42 and
15.30 m mol TE/g db, respectively (Aziz et al. 2012). Our data on
antioxidant activity for mango powder were comparable to those
reported previously.
