Abstract:
The nutritional components of Tricholoma giganteum cultivated with Mikania micrantha was studied in this study, and results showed that the content of total sugar, polysaccharide, crude fiber, crude fat, crude protein and ash were 54.24 g, 13.42 g, 5.52 g, 1.60 g, 15.55 g, 6.21 g in per 100 g dried fruiting body of Tricholoma giganteum, respectively. Tricholoma giganteum contained 17 essential amino acids, andthe total amount of amino acids was 15.13 g/100 g, of which essential amino acids accounted for 40.38%. The ratio of essential amino acids to non-essential amino acids (E/N) was 0.68, which met the requirements of FDA and WHO that the essential amino acid content of ideal protein should be above 40% and E/N should be above 0.6. In addition, the mineral elements content of K, Na, Ca, Mg, Cu, Zn, Fe and Mn was 27.58 g/kg, 0.24 g/kg, 0.23 g/kg, 0.90 g/kg, 69.72 mg/kg, 55.52 mg/kg, 51.46 mg/kg and 10.05 mg/kg, respectively, and the content of toxic heavy metals such as lead, cadmium and total arsenic content was lower than the limit standards for heavy metal content of edible fungi. Total mercury content was slightly excessive. The results of this study provided a theoretical basis for the further development and utilization of M. micrantha cultivated with T. giganteum and a new method for the comprehensive control of M. micrantha.
