Characterization Of Key Odorants In Cumberland Rosemary, Conradina Verticillata, Claire Mackenzie Gorman
Masters Theses
Conradina verticillata Jennison, commonly known as Cumberland Rosemary, is a threatened plant from the mint family Lamiaceae. This species is a flowering, perennial shrub found in only a few counties of Kentucky and Tennessee. Cumberland Rosemary possesses a unique aroma profile; however, the odorants responsible for its aroma have not been previously identified. In this study, a total of 32 odorants were identified in Cumberland Rosemary using gas chromatography-olfactometry (GC-O) and gas chromatography-mass spectrometry (GC-MS). Odorant flavor dilution (FD) factors were determined through the application of aroma extract dilution analysis (AEDA). Seven odorants with FD factors ≥ [greater than or …

Aroma Chemistry Of Daldinia Childiae Fermentation, Andrew Jason Moore
Masters Theses
An investigation to identify odorants responsible for a pleasant woody perfume-like aroma produced in the fermentation broth of the fungus Daldinia childiae (J.D. Rogers & Y.M. Ju) was conducted. Thirty odorants were identified from 30-day old fermentations employing solvent-assisted flavor evaporation (SAFE) and aroma extract dilution analysis (AEDA). Eleven odorants with flavor dilution (FD) factors ≥ 16 were quantitated using stable isotope dilution assays (SIDA), and odor activity values (OAV) determined. Odorants with the highest OAVs included guai-11-en-10-ol (woody, OAV 102689), 1-octen-3-one (mushroom, OAV 9025), sotolon (maple, OAV 458), and (2E)-non-2-enal (fatty, OAV 70). An odor-simulation model formulated …
