Comparative Study of Nutritional Profile of Wild and Domesticated Oyster Mushroom (Pleurotus ostreatus)

Abstract

This study was carried out to determine the nutritional profile of wild and domesticated oyster mushroom. The wild mushroom was collected from forests around Owo and identified while the domesticated sample was grown on wood substrate prepared in the laboratory. Thereafter, the proximate composition and the mineral content were determined using standard techniques. The result of the proximate composition of the wild and domesticated P. ostreatus mushroom revealed that the moisture content and the Nitrogen free extract of the wild (8.96 % and 52.50 %) and the domesticated (8.59 % and 52.16%) mushrooms were comparable whereas, crude protein (32.11 %) and crude fibre (13.51 %) were significantly higher in the wild type than the domesticated samples. Also, lipids (0.42 %) and ash content (4.17 %) were significantly higher in the domesticated sample compared with the wild type. In the mineral content assay, nitrogen was found higher in the wild mushroom than the domesticated sample while potassium, calcium and magnesium were found to be higher in the domesticated samples than the wild types. Only phosphorus was found in comparable amount in both the wild and domesticated type of the mushrooms. Overall, there appears to be no significant (p<0.05) differences in the nutritional content of both the domesticated and wild-collected test mushroom.
