Abstract:

The contents of protein, mineral, carbohydrate, ash and VC in the fruit bodies of Termitomyces robustus and Termitomyces striatus were measured, and their flavor-active compounds were identified by comparison with taste thresholds of amino acids. The results showed that T. robustus and T. striatus were high in Mg, Ca, Fe, Zn and P. Glutamic acid was the most dominant amino acid in both, accounting for 0.55% and 0.19%, respectively. Moreover, 7 kinds of essential amino acids accounted for 41% and 50% of the total amino acids, respectively. The levels of protein and crude fat were between those of vegetables and meat, and closer to vegetables. The content of vitamin C was abundant. Therefore, the two species of Termitomyces are highly nutritional and the flavor is attributed to the higher contents of aspartic acid and glutamic acid.

Key words: T. robustus, T. striatus, fruit body, nutrient component
