LWT - Food Science and Technology, 2009 The objective of the present investigation was the optimization of the extraction of volatile compounds of the summer truffle aroma (Tuber aestivum) by headspace solid-phase microextraction (HS-SPME) using fibres of different polarity able to provide complementary information. A response surface experimental design was applied considering three factors

Odour composition of the summer truffle, Tuber aestivum
Transactions of the British Mycological Society, 1987Volatile substances from Tuber aestivum have been studied by gas chromatography coupled to a mass spectrometer (GC-MS). Thiobismethane is the main compound, mixed with oxygen-containing organic compounds with molecular masses between 46 and 88. The qualitative composition of odour could be useful as a taxonomic character.

Abstract Changes in the aroma composition of truffles (Tuber aestivum and Tuber melanosporum) after electron-beam and gamma irradiation at doses of 1.5 kGy and 2.5 kGy were investigated by solid phase microextraction methodology (HS-SPME). In particular, the effect was evaluated on specific compounds chosen for their aromatic importance according to ...

Elemental analysis of summer truffles Tuber aestivum from Germany
Journal of Radioanalytical and Nuclear Chemistry, 2019In an attempt to characterize inorganic constituents in Tuber aestivum, the summer truffle, samples from four different German states were collected by the “hypogea research group” for analytical investigations. Forty three elements in truffles, peridium and gleba were determined by three independent analytical techniques, PGAA, INAA and ICP-MS.

Abstract The aromatic composition of two different species of truffles (black and summer) was evaluated by gas chromatography–olfactometry (GC–O). Volatiles released by the truffles at 25 °C for 7.5 h were collected in a trapping system consisting of 400 mg of LiChrolut EN kept at 0 °C and further eluted with dichloromethane/methanol (95:5).

Identification of Dipteran species inhabiting Tuber aestivum (the summer truffle) ascomata
Environmental Monitoring and AssessmentTuber spp. (Ascomycota) forms hypogeous fruiting bodies (truffles) that host many microbial species as well as invertebrates which feed on them. Despite the larvae and adults of Diptera and Coleoptera are commonly found to inhabit truffles, molecular investigations assessing their occurrence are still few and the number of species is probably ...

The target of this observational study was the summer truffle Tuber aestivum (Pezizales, Ascomycota, Fungi), an ectomycorrhizal species widely distributed in Croatian forest habitats and known for its broad ecological tolerance. Although T. aestivum has been commercially exploited in Croatia for decades, available data on this species remain sparse and
