| Abstract: | "The fragrant bolete, Suillus punctipes (Peck) Singer, is an edible mushroom with a unique aroma reminiscent of mushroom and citrus peel with an undertone of apricot. Thirty-five odorants were identified using solvent-assisted flavor evaporation (SAFE) and aroma extract dilution analysis (AEDA). Fourteen odorants including those with flavor dilution (FD) factors >/=64 were quantitated using stable isotope dilution assays (SIDA). Some odorants with high OAVs included 1-octen-3-one (OAV 164368), 1-octen-3-ol (OAV 3421), linalool (OAV 812), and nonanal (OAV 487). An odor simulation model was prepared closely matching the aroma of the mushroom. Omissions experiments revealed that 1-octen-3-one, 1-octen-3-ol, (2E)-oct-2-enal, linalool, delta-dodecalactone, and a mixture of three aldehydes, octanal, nonanal, and decanal, were essential odorants for the aroma profile. Enantiomeric ratios were determined for several odorants employing chiral chromatography. The results from this study lay the groundwork for future studies in the aroma chemistry of S. punctipes and other mushrooms from the Suillus genus" |
