4. ORAC method
The antioxidant activity measured by ORAC for dried powders from different drying methods was 408e651 m mol TE/g db
(Fig. 2d). Statistical analysis indicated significant change in ORAC values of powders with different dryers used (p 0.05), however, FD and IRD samples values did not vary significantly. Hung (2012) reported that hydrophilic ORAC values varied from 32 to
62.1 m mol TE/g db whereas lipophilic ORAC values varied from 1.2 to 2.5 m mol TE/g db in dehydrated mango flesh using sun, air, freeze, vacuum and microwave techniques. The ORAC value obtained in present study are higher than reported values in literature which might be due to variability in material used.
