[en] The study involved seven cultivars of white sorghum selected to ISRA Bambey and consumed in many regions of Senegal. Several characters and biochemical compounds of the grains (presence of pigmented testa, total phenols, condensed tannins and antioxidant activity) were determined in all cultivars. A three days malting was also carried out and amylolytic enzymes such as α-amylase, β-amylase and limit-dextrinase which are essential for a malt of good quality were proportioned. These enzymes are measured specifically with kits of Megazyme: Amylazyme (α-amylase), Betamyl (β-amylase) and Limit-Dextrizyme (limit-dextrinase). Two cultivars, CE 180-33 and CE 145-66 proved to be tannin sorghums, have the highest levels in total phenols and the most important antioxidant activities (ABTS and DPPH). The results of enzymatic analysis and the index of Kolbach indicated the F-2-20 like cultivar presenting the best potentialities for malt production
