摘要: ABSTRACT Potato (Solanum tuberosum) is a popular staple food in South Africa, whereas cocoyam (Colocasia esculenta) remains unpopular and not well known outside KwaZulu-Natal Province, where it cultivated mainly for subsistence. A comparative study of the nutritional compositions commercially available tubers both crops Africa was carried out. The results showed that two were high carbohydrate energy but low lipid contents. Although potato significantly higher moisture ash than cocoyam, carbohydrate, caloric crude protein contents different (P < 0.05) tubers. Whereas boiling improved availability protein, fiber species, reduced crops. Manganese levels detectable, iron appreciably high, magnesium copper average range cooking level (11.20–9.95 mg/100 g DM), significant increase observed (9.08–13.87 mg/100 g DM). Cooking lowered magnesium, potassium Oxalates phytate when compared with potato. remarkably anti-nutrient tubers. PRACTICAL APPLICATIONS This provides evidence have very close values. Cocoyam favorably even excelled some nutrients. Thus, consumption could be encouraged popularized as an additional tuber crop.
