| Abstract: | "The American Matsutake, Tricholoma magnivelare (Peck) Redhead, is an edible wild mushroom with a distinctive aroma described as mushroom and spice with subtle floral and citrus nuances. In this study, a total of 36 odorants were identified from T. magnivelare using solvent-assisted flavor evaporation and aroma extract dilution analysis. Stable isotope dilution assays were performed to quantitate 14 odorants with flavor dilution factors >/=64. Odorants with high odor activity values (OAVs) included 1-octen-3-one (OAV 2125), linalool (OAV 650), (2E,4E)-nona-2,4-dienal (OAV 304), and 1-octen-3-ol (OAV 206). An odor simulation model matched the odor profile of the fresh mushroom. Omission studies showed that linalool, hexanal, (2E,4E)-nona-2,4-dienal, methyl (E)-3-phenylprop-2-enoate, and 1-octen-3-one or 1-octen-3-ol were essential to the aroma of T. magnivelare. Chiral chromatography showed that alpha-pinene was a scalemic mixture of 34% (R)-(+) to 66% (S)-(-), while 1-octen-3-ol was present as 95% (R)-(-) to 5% (S)-(+), and linalool was 96% (R)-(-) to 4% (S)-(+). These results establish the base for future investigations into the aroma chemistry of other members of the genus Tricholoma" |
