Abstract :
The availability of cheaper food energy sources which compares favourably with other high priced cereals is of importance and should be encouraged. This study investigated the proximate/anti-nutritive contents of cocoyam collected from Southern Nigeria and Eastern Uganda to investigate if agronomic or climatic factors play a role in its composition. The proximate/mineral composition of cormels (crude protein:0.35 – 6.9%; carbohydrates: 60.01 – 83.66%; Fe: 3.65 - 16.80 mg/100g, Zn: 1.39 – 2.45 mg/100g) show that cocoyam can conveniently replace yams and potatoes in diets due to its similar carbohydrate contents though lower in crude fibre content (0.99 – 2.80%). Cocoyam samples contained high anti-nutrients (Cyanides 0.94 – 2.16 %; Oxalates 8.45 – 181.4 mg/Kg) which may limit its utilization. An analysis of variance indicate cocoyam differ significantly (p 0.05) in proximate/anti-nutritive contents across the two locations with a higher content of crude fibre, crude protein and carbohydrates observed in samples collected in southern Nigeria.
