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.
