| description | Oyster mushroom nutrients have been rated side by side with proteins in meat and eggs. Oyster mushrooms are high in vitamins and essential amino acids, but their cultivation is poor. Oil palm fibre is being used in making material strength in mechanical engineering with little or no use in the cultivation of food products. This study determined the physicochemical properties and storage stability of mushrooms cultivated on single and mixed substrates (sawdust and oil palm fibre). Oil palm fibre mixed with sawdust at different ratios (95:5, 90:10 and 85:15) was used to grow oyster mushrooms in other to turn waste to wealth. The oyster mushrooms cultivated on both single and mixed substrates were subjected to proximate composition analysis (22.99, 4.54, 6.93, and 6.98%, for crude protein, fat, fibre, and ash), mineral content (5.92 mg/100 g for sodium and 25.76 mg/100 g for potassium), amino acid profile (155.85 mg/g for a total essential amino acid), fatty acid profile (43.82% for linoleic acid), anti-nutritional factor, and storage stability for three months. The mushrooms cultivated on the mixed substrate (oil palm fibre + sawdust) have a higher proximate composition, mineral content, amino acid profile, and fatty acid profiles than mushrooms cultivated on a single substrate (sawdust). Although the peroxide value of the oyster mushroom samples from the mixed substrates increased with storage time, the peroxide value was lower than 10 meq/kg of fat throughout the storage period, which means the samples could still be considered stable during storage. Cultivation of oyster mushrooms on mixed substrates of oil palm fibre and sawdust should be encouraged for highly nutritious oyster mushroom production. Oil palm fibre can also serve as a raw material in mushroom cultivation. |
