Indigenous Sudanese sorghum-based food: Secondary metabolites and antioxidant activities of traditional Sudanese nonalcoholic beverage from two sorghum landraces.

is a Sudanese traditional nonalcoholic beverage that is made from sorghum flour. This work determined the secondary metabolites and antioxidant activities of traditional Sudanese nonalcoholic beverage from two local sorghum landraces Abjaro and Hegarii. The changes on the total phenolic content (TPC), total flavonoid content (TFC), carotene content, tannins, and antioxidant activity (DPPH, reducing power, and FRAP) were estimated during the preparation of the flasks. For both landraces, a significant ( < .05) effect on the phytochemical compound and the antioxidant activity was observed during malting and fermentation of sorghum flour. However, the most increase in the TPC and carotene content was observed, whereas tannin and TFC were decreased in the flasks compared with the malted and fermented samples. The antioxidant activity DPPH, TRP, and FRAP was significantly ( < .05) higher in flasks than those of raw and processed flour. The partial least squares regression test stated a positive validation score of the flasks prepared from the both landraces. In conclusion, drink from Abjaro and Hegarii landraces contain high antioxidants compound, which could improve the health-promoting metabolites in Sorghum-based food.
