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.
是一种由高粱粉制成的苏丹传统非酒精饮料。这项工作测定了来自两个当地高粱地方品种Abjaro和Hegarii的传统苏丹非酒精饮料的次生代谢产物和抗氧化活性。在制备烧瓶的过程中，估计了总酚含量（TPC）、总黄酮含量（TFC）、胡萝卜素含量、单宁和抗氧化活性（DPPH、还原力和FRAP）的变化。对于这两个地方品种，在高粱粉发芽和发酵过程中，观察到对植物化学化合物和抗氧化活性有显著（<0.05）影响。然而，与发芽和发酵样品相比，在烧瓶中观察到TPC和胡萝卜素含量增加最多，而单宁和TFC减少。烧瓶中的抗氧化活性DPPH、TRP和FRAP显著（<0.05）高于生面粉和加工面粉。偏最小二乘回归测试表明，由这两个地方品种制备的烧瓶具有正验证分数。总之，来自Abjaro和Hegarii地方品种的饮料含有高抗氧化剂化合物，这可以改善基于高粱的食品中促进健康的代谢产物。
