Studies on the production, chemical composition and nutritional value of mushroom
… brunnescens. Dried fruitbodies were subjected to proximate analysis, and protein, carbohydrates, fat, moisture, ash, and amino acid contents were determined. Diets containing 10% mushroom protein resulted in PER of 1.5 and NPR of 0.74 compared with values for casein of 2.7 and 2.4, respectively. …
