Abstract

A comprehensive study was carried out to compare the nutritive value of black and white Fonio, both of which are of West African origin. Standard methods of analysis was used to analyses the proximate and some mineral composition of the both grains. The nutritive value such as crude protein, crude fat, crude fiber, carbohydrate, moisture and ash content was determined. Minerals such as sodium and potassium were determined using flame photometry; while zinc, iron and calcium were determined using atomic absorption spectrometry. The result shows that black Fonio contains 8.75% crude protein, 4.00% crude fat, 1.03% crude fiber, 76.91% carbohydrate, 2.31% ash, 7.00 % moisture, sodium (Na) 30mg/100g, potassium (K) 8.45mg/100g, calcium (Ca) 30.00mg/100g, Iron (Fe) 2.75mg/100g, Zinc (Zn) 0.75mg/100g while that of white Fonio was found to contained 7.11% crude protein, 3.00% crude fat, 0.79%crude fiber, 79.72% carbohydrate, 2.13% ash, 7.00% moisture, sodium (Na) 20.00mg/100g, Potassium (K) 5.40mg/100g, Calcium (Ca) 20.00mg/100g, Iron (Fe) 1.10mg/100g, Zinc (Zn) 0.65mg/100g. The result shows that black Fonio is more nutritive than the white Fonio.
