Proximate and mineral composition of four edible mushroom species from South Western Nigeria

Abstract

Results of proximate analysis of four edible species of mushroom collected from Akoko land in Ondo state, Nigeria indicate that Termitomyces mammiformis was a very good source of crude protein (37%), crude fiber (7%), ash (10%), calcium (216 g/kg dry weight) and manganese (136 mg/kg dry weight (dw)). Russula vescawas the richest in carbohydrate (71%) and magnesium (14 g/kg), while Lactarius triviralis was richest in moisture content (37%), iron (1230 mg/kg) and copper (8 mg/kg). It is also a good source of carbohydrate (64%), calcium (210 g/kg) and manganese (120 mg/kg). Lentinus tigrinus was, however, the richest in dry matter (94%), and is also rich in carbohydrate (62%), magnesium (11 g/kg) and copper (6 mg/kg). It was observed that lipids, sodium and phosphorus contents of the four species were generally very low. Key words: Edible mushrooms; food composition.
