ABTS activity was quantified in terms of percentage inhibition of
the ABTS
+
radical cation by antioxidants in each sample. There was a
significant variation in the percentage inhibition of meat from goat
diets (90.15–93.51% inhibition) (Table 5). Moringa was once again the
most efficient scavenger of the radical (93.51%). Meat from goats
supplemented with SC (91.89%) and GH (90.15%) also exhibited high
scavenging activity. The ABTS is a stable free radical cation applicable
to both lipophilic and hydrophilic antioxidants that has been used to
measure the total antioxidative activity (Kim & Lee, 2009). Meat
samples from all dietary supplementations showed a potential electron
donating ability. The fact that meat from goats supplemented with MOL
had the highest ABTS
+
reducing activity suggests that these samples
had the highest potential to donate electrons for neutralising free
radicals
