Fig. 2 Fe 2+ chelating antioxidant activity (%) of the sample (WUF—Whole unfermented sample,
WF—Whole fermented sample, DUF—Defatted unfermented sample, DF—Defatted fermented
sample)
by IC 50 value in Table 2. Sachharomyces cerevisiae fermented flaxseed extracts had
higher metal chelating activity than unfermented flaxseed extracts.
3.6 ABTS Radical Scavenging Activity
The ABTS radical assay is a widely used method of screening for antioxidant activity
and is reported as a decolorization assay. The scavenging effect of the extracts is
showed in Figure 3. The ABTS scavenging activity of the fermented and unfermented flaxseed extracts was presented by IC 50 value in Table 2. Defatted S. cerevisiae fermented flaxseed extracts had higher ABTS radical scavenging activity than
unfermented and whole fermented seed extracts. Similar result has been reported on
L. plantarum fermented myrtus communis berries (Curiel et al. 2015).
3.7 Ferric Reducing Antioxidant Power Activity (FRAP)
The ferric reducing antioxidant power activity of unfermented and fermented flaxseed
extracts was presented in Table 2. It was clear from the results that the FRAP activity
of fermented flaxseed extracts were the highest among the unfermented extracts.
