Identification of Bis(methylsulfanyl)methane and Furan-2(5 H)-one as Volatile Marker Compounds for the Differentiation of the White Truffle Species Tuber magnatum and Tuber borchii

​Some truffles are expensive and, therefore, are prone to food fraud. A particular problem is the differentiation of high-priced Tuber magnatum truffles from cheaper Tuber borchii truffles, both of which are white truffles with similar morphological characteristics. Using an untargeted approach, the volatiles isolated from samples of both species were screened for potential marker compounds by comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry (GC×GC-TOFMS) and statistical analysis of the obtained semiquantitative data. Results suggested bis(methylsulfanyl)methane and furan-2(5H)-one as compounds characterizing T. magnatum and T. borchii, respectively. Exact quantitation of both volatiles by conventional one-dimensional gas chromatography-mass spectrometry in combination with stable isotopologues of the target compounds as internal standards confirmed both as marker compounds. The method is suitable to be used in the routine analysis for the objective species differentiation of T. magnatum and T. borchii.

Scottish forest holds key to rare truffle's origins

Naturalists have stumbled upon a rare species of truffle nestled within a Scottish forestry plantation earmarked for transformation into an Atlantic rainforest habitat.
As The Guardian reports, the finding of the Chamonixia caespitosa, a type of truffle typically found in the Alps and Scandinavia, near Creagan in the west Highlands, presents a unique paradox: as efforts to remove non-native Sitka spruce trees for rewilding intensify, the habitat supporting the truffle faces destruction.
This globally rare fungus, inedible to humans, shares a symbiotic relationship with the Sitka spruce, its white fruit turning a striking mottled blue upon contact with the air. The mystery surrounding its presence in Scotland prompts naturalists to ponder its origins, considering the unlikely dispersal of fungus spores to the UK and the Canadian origin of the Sitka plantations.
Dr. Andy Taylor, a molecular fungal ecologist at the James Hutton Institute, suggests the possibility of a broader distribution, advocating for the preservation of this rare species. He highlights the importance of understanding and conserving soil biodiversity within such plantations, spearheading an initiative to study soil species in other areas.
Despite the ecological criticism surrounding Sitka spruce plantations, Taylor's research indicates a potential richness in soil biodiversity, offering hope for the discovery of new species and insights into their symbiotic relationships with host trees. As conservation efforts evolve, the discovery of the rare truffle serves as a catalyst for further exploration and preservation of Scotland's natural heritage.
