The present work aimed to deepen knowledge on the properties of sorghum malt used for tchakpalo production
in Benin. It focused on the physico-chemical characterization of white and red varieties of sorghum malt
samples, compared to an imported Nigeria’s variety named Farafara, selected for its brewing properties. The
malts were produced and the physico-chemical parameters of malted and unmalted grains were performed. The
efficiency of crushing using maize or hammer mill was also investigated and compared. Results obtained
indicated that the dry matter of white and red sorghum varieties samples were respectively 89.44±0.21% and
90.15±0.20%. The thousand kernel weights were respectively 34.66±0.33g and 31.79±0.35gand the germination
rates were 97.66±1.2% and 75.33±1.5%. The protein content of Benin’s white and red varieties and imported
variety ranged from 9.75±0.7 % to 12.21±0.1 % whereas ash content were ranged from 1.25± 0.02 to 1.4±0.04%.
The phenolic compounds content of Benin and imported variety were 0.49±0.01, 1.77± 0.02 and 0.76g±
0.02/100gDM respectively while oxalate content of samples varied from 0.33± 0.01 to 1.39±0.06g/100g DM
respectively. The crushing tests showed that the maize mill was not suitable for sorghum malt crushing. Based on
the present study, sorghum varieties from Benin could present physico-chemical characteristics that predispose
them for malting. However we recommend to producers constituting cooperative to acquire specialized mills
which could enable them to get groat for good extraction during brewing |
