Abstract

The malting properties of maize and sorghum were analyzed according to the method of the institute of Brewing (1.0.B) 1977. Germination was done for 5 days at 30^oc. The parameters evaluated included a thousand corn weight (30g and 20g) for both yellow maize and red sorghum respectively), moisture content (9% and 6% for both yellow maize and red sorghum respectively), germinative energy (96% and 88% for yellow maize and red sorghum respectively), water sensitivity (86% and 92% for yellow maize and red sorghum respectively), germinative capacity (96% and 88% for yellow maize and red sorghum respectively), cold water extract (41. 5 kg/⁰L and 51.2 kg/⁰L for yellow maize and red sorghum respectively), hot water extract (200.94 kg/⁰L and 129.63 kg/⁰L for yellow maize and red sorghum respectively), result observed where however satisfactory due to the fact that the maize and sorghum could be used as a substitute for barley in commercial brewing.
