Tuber melanosporum Identity & Plant Part
The botanical entity is Tuber melanosporum Vittad., the black truffle, an ascomycete fungus that lives with the roots of oak and hazel trees. The part used is the fruiting body, the underground, dark, warty structure that ripens in winter and is traditionally located with trained animals. Mycelium and fermentation broth are not part of this ingredient.
Other truffles are different species, among them Tuber aestivum, the summer truffle, and the white truffle, Tuber magnatum. Truffle extract carries heteropolysaccharides built from mannose, glucose and galactose, proteins and fungal sterols, named here as families only. The sulfur-containing volatiles that make truffles smell do not end up in this extract.
