BACKGROUND: Sorghum grains are rich in phenolic compounds, which are noted for their anticancer, antioxidant, and anti-inflammatory properties, as well as volatile compounds (VOCs) that contribute to aroma and fermentation processes. There is a known close relationship between sorghum coat color and phenolic compound content (PCC), particularly flavonoids which are pigments that confer red and purple colors in flowers and seeds.RESULTS: Our results showed that black seeds had the highest total tannin content (TTC) and ketone content, which were measured at 457.7 mg CE g-1 and 96 g 100 g-1, respectively, which were 4.87 and 1.35 - fold higher than those of white seeds. L* showed a negative correlation between TTC (r = -0.770, P
