Abstract:
Tylopilus microsporus belongs to the Boletaceae family, and is sourced from Luliang County, Qujing City, Yunnan Province. The analysis results of the nutritional composition of Tylopilus microsporus shows that Tylopilus microsporus is rich in nutrients, and the main nutritional components (g/100 g) were: crude protein 29.9, crude polysaccharide 3.68, essential amino acid 11.18, and total amino acids 23.80. The essential amino acids to non-essential amino acids (E/N) index was 0.89, and the essential amino acids to total amino acids (E/E+N) was 46.97%. The total essential amino acids meet the FAO/WHO standard mode, with balanced nutritional composition. The EAAI value (essential amino acid index) was 1.05. Tylopilus microspores was rich in mineral nutrients, mainly including Ca, K, Mg, P, Fe, Cu, Mu and Se, in particular, the K content was high. A total of 949 metabolites were identified from Tylopilus microsporus, in which 798 metabolites, including 10 superclasses, matched to the human metabolic database. There were multiple active metabolites with relatively high contents. Tylopilus microsporus is a wild bolete with high protein content and low sugar content. Its amino acid content was high and had a relatively complete range of species. Meanwhile, the content of bitter amino acids and potassium content provide an important basis for bitter research and development utilization of new boletes.
