Abstract

In this study partial substitute of barley malt by effective use of maize, potato and enset were investigated using saccharomyces cervisiae. Barley malt is the principal ingredient in the manufacturing of beer and has traditionally been the grain of choice in the brewing industry. However, it is not always economically feasible to brew with 100% malted barley, and at present time breweries are forced to minimize their costs without changing the quality of their beer. Therefore, this study was utilized Maize, Potato and Enset starch as a partial substitute for barley malt and to evaluate some physico-chemical quality attributes of the beer. All the experiments were conducted Dashen Brewery S.C, Ethiopia. The beer underwent four series of experiments in triplicate involving the starch from the three crops (50%, 62.5% and 75% starch substitute from each) with full barley malt serving as a control. The major attributes of the beer (alcohol content & flavor) were evaluated for each of the 50%, 62.5% and 75% substitutes from the three crops with reference to the control beer. The results showed that 75% substitution of barley malt with Maize and Enset starch is promising in the beer production.
