Finally, the different assays used in the present study showed
that extracts from white sesame seed had relatively higher antioxidant
capacity than extracts from gold sesame seeds. This was most
likely due to the differences in the contents of antioxidants as both
seeds types had the same composition. In fact, Moazzami et al.
(2007) quantified sesaminol glucosides in 65 different sesame seed
samples and found that their contents varied depending on seed
sample; however, there were no significant differences between
black and white seeds, indicating that sesaminol glucosides contents
did not necessarily depend on seed color. Wankhede and
Tharanathan (1976) noted that composition of sesame seeds could
vary according to growing conditions of sesame plants; as our samples
were imported from two different countries (Turkey and Paraguay),
this would explain the differences between white and gold
sesame seed extracts observed here.
