Production of cocoyam, cassava and wheat flour composite rock cake

Abstract

The proximate and sensory analysis of the cassava-cocoyam supplemented wheat flour rock cake has been made. This was done to investigate the nutritional value and the general acceptability of the cassava flour and cocoyam flour supplemented rock cake. The proximate analysis indicate that the moisture content, ash and the carbohydrate increase with increasing cassava and cocoyam flour concentration. Generally the ash content of composite rock cakes increases as the level of supplementation increases implying that the inorganic nutrients in the composite rock cake is richer than that of wheat rock cake. It is observed from the organoleptic analysis that generally, whole wheat rock cake and cassava and cocoyam supplemented rock cake with cassava and cocoyam flour up to 30% is preferred to rock cake with cassava and cocoyam flour beyond 30%. Thus cassava and cocoyam flour can be used to substitute for wheat flour up to about 30%. ©Asian Network for Scientific Information, 2010.
