2.8.3. Antioxidant Activity

The antioxidant activity of GBF samples was determined through the use of the ferricreducing-ability-plasma (FRAP) with slight adjustment as described by Hofmann et al. [24]. The method involved the use of 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) to assay the scavenging activity [25] of green banana flour. Trolox stock was used as standard, and the absorbance was read at 517 nm. The results were expressed as μM Trolox equivalent per 100 g of green banana flour (d.w.).
