The proximate analysis and mineral elements of the fruiting body of Pleurotus tuberregium were investigated to ascertain its nutritional and clinical implications.The protein content, crude-fibre, crude-fat, moisture and ash contents were determined using standard methods, the mineral elements was determined using atomic Betaine HCL (TMG) absorption spectrophotometry.Results indicated that Pleurotus tuber-regium contained 84.2% moisture, 19% crude fibre, 28.19% carbohydrate, 5% crude fat, 16.
2% ash and 31.52% protein.It contained the following mineral elements (parts/million): calcium, 1.8; copper, 0.2; zinc.
0.l0; potassium, 0.37; sodium, 1.49 and iron, 13.3.
This indicates that edible mushroom is a very good source of both macro and micronutrients.These findings were discussed in line with its Small Push Catch nutritional and clinical importance.
