Most of the sesame traded in the world market is light seeded; only seed coats of landraces vary from white to black (Langham and Wiemers, 2008).
In a study
conducted by da Silva et al. (2011), comparing the
chemical composition of beige and black sesame seeds,
it was observed that black sesame seeds display the
highest rates of soluble phenolic compounds and phytates, besides having a higher capacity of holding
free radicals and having a potential related to a
significantly greater antioxidant activity. According to
Queiroga et al. (2010a), black sesame seeds stand out in
relation to others (BRS silk and CNPA 4) white and
beige, for they show a high concentration of calcium (Ca)
and sulphur (S) minerals.
