摘要

Black truffle (Tuber melanosporum) aromas from two different areas of Southern France: i) Tricastin (Richerenches) and ii) Alpes de Haute Provence (Simiane) have been studied by two different extraction methods: a) extraction using pentane and ethyl ether as the solvents, and b) solid phase micro extraction (SPME). A total of 131 compounds have been identified by GC/MS and retention indices. Chemical composition was found to be different according to areas and extraction methods. An interesting fraction of black truffles from Tricastin, obtained by SPME method, consisted of heterocyclic compounds most likely arising from the Maillard reaction between acetoin, 1,2-propanediol and hydrogen sulfide (furfural, furfuryl alcohol, 2- and 3-formylthiophenes, 2-acetylthiazole...). Some usual monoterpene hydrocarbons, citronellol, sesquiterpene hydrocarbons (beta-caryophyllene, daucene) and fused aromatic compounds (methyl- and dimethylnaphthalenes), in the Tricastin sample or by solvent extraction with pentane were also identified. Several aliphatic alcohols, acids, aldehydes and sulfides were also found. It is suggested that methoxylated benzenes and toluenes (mono, di, tri, and tetra derivatives) obtained by ether extraction, as well as 1,2,5,6-tetrahydropyridine contribute to the characteristic odor and aroma of black truffles. The quantitative composition varies depending on the separation method and thus it cannot be taken into account.
