ABSTRACT
In this study, the antinutrient contents of fonio grains was investigated using standard laboratory procedures. The results revealed their presence in different concentrations. Tannin was the highest (24.843±0.095mg/100g), following by HCN (4.590 ± 0.001) and Oxalate (1.390 ± 0.035mg/100g) while phytate had the least concentration (0.837 ± 0.028mg/100g). The antinutrient content in fonio grains were however low hence may not cause nutritional deficiencies on regular consumption.
