Proximate Analysis and Mineral Composition of the Fruiting Body of Pleurotustuberregium (Mushroom) Cultivars from South East Nigeria.
Main Article Content
Abstract
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 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 nutritional and clinical importance.
