An Inter-Species Comparative Study on the Distribution of Nutrients in Selected EdibleMushrooms in Ekiti State, Nigeria
Journal Title: Haya: The Saudi Journal of Life Sciences - Year 2018, Vol 3, Issue 6
Abstract
Abstract:The present investigation was carried out to determine and compare the nutritional values of some selected edible mushrooms collected in Ekiti State, Nigeria such as Pleurotus sajor-caju, Termitomyces robustus, Lentinus squarosullus, Termitomyces microcarpous, Termitomyces clypeatus, Lentinus tuber-regium and Polyporus sp. Proximate composition, mineral composition as well as vitamins A and C contents of the mushrooms were determined using standard methods. Results revealed significant differences in the nutritional composition of the mushrooms though some had similar compositions. The overall nutritional composition of the mushrooms was quite good suggesting that they have potentials to address the nutrient deficiency prevalent in the state, particularly among the low income earners. The values (%) ranged from 6.61-9.75 for moisture content, 1.07-3.89 for fat, 1.61-10.60 for total ash content, 1.61-10.81 for crude fibre, 8.67-37.31 for protein and 49.90- 75.35 for carbohydrates. The mineral composition (mg/100g) ranged between 24.96-126.66 (Na), 478.30-789.64 (K), 33.06-153.43 (Mg), 38.17-440.20 (Ca), 1.23- 14.03 (Mn), 12.84-151.14 (Fe), 3.58-14.55 (Zn) and 0.92-4.03 (Cu). Vitamin A content (mg/g) was very low ranging from 0.01-0.12 while vitamin C content ranged from 94.22-326.51. The present study contributes to the elaboration of the nutritional database of commonly consumed mushrooms in Ekiti State, Nigeria. Keywords: edible mushrooms, nutritional composition, proximate composition, mineral composition, vitamins A and C.
