Proximate Analysis and Mineral Element Composition of False Yam ( Icacina trichantha) Tuber and Oyster Mushroom ( Pleurotus ostreatus)

Abstract

False yam (Icacina trichantha) tubers and oyster mushroom (Pleurotus ostreatus) were analyzed for proximate composition and mineral composition. The analysis revealed that false yam contained a higher concentration of carbohydrate (91.93% against 49.15% of oyster mushroom) while oyster mushroom contained a higher concentration of protein (46.38% against 5.25% of false yam). Results obtained in this study also revealed that false yam contained a higher amount of magnesium (13.32%) and calcium (18.74%) while oyster mushroom contained a higher concentration of potassium (13.08%) and sodium (21.80%). Both plants had iron and zinc at tolerable level (1.00). This shows that false yam and mushroom have compositions that are similar to other edible root tubers and can be used a s foods.
