ABSTRACT

Dioscorea rotundata (white yam) and Colocasia esculenta (white cocoyam) were analyzed for their proximate and mineral compositions. The result showed that Dioscorea rotundata has a moisture content 54.50%, ash content 1.4%, crude fat content 2.70%, crude protein content 0.087%, crude fibre content 0.70%, carbohydrate content 40.61%, available energy 731.75 kJ; while Colocasia esculenta has moisture content 38.50%, ash content 1.60%, crude fat content 1.05%, crude protein content 0.066% crude fibre content 1.0%, carbohydrate content 57.78%, available energy 1022.27 kJ. The mineral content of the analyzed samples showed that Dioscorea rotundata and Colocasia esculenta were rich in iron of values 81.85 mg/100 g and 59.07 mg/100 g respectively. The copper content of the samples were 10.06 mg/100 g and 6.72 mg/100 g for Dioscorea rotundata and Colocasia esculenta respectively.
