In this paper, with poplar wastes for the cultivation of Lentinus edodes, and using the Kjeldahl fixed nitrogen method, Soxhlet extraction method and gravimetric method, phenanthrene Lin agent method and spectrophotometric method has carried on the analysis to the mushroom nutrition composition of protein, fat, crude fiber, carbohydrates and amino acids. The results showed that the protein content of 18.63%, fat content in letinous edodes crude fiber content of 4.24%, 6.24%, 4.94% for reducing sugar content and amino acid content is 32 g/100g.
Keywords: Poplar offal; letinous edodes; nutritional components; analysis
