Caracterización química y sensorial de vinos Tempranillo envejecidos en barricas de roble Quercus alba de diferentes orígenes geográficos
… con los valores de actividad olfativa (OAV) total más altos. Las barricas de Pensilvania aportaron los contenidos más elevados de fenoles volátiles, guayacol y vainillina; y las barricas de Misuri aportaron los contenidos más elevados de compuestos furánicos y β-metil-γ-octalactonas, y …

Identification of rotundone as an important contributor to the flavor of oak aged spirits
… and calculation of their odor activity values (OAVs) demonstrated rotundone’s importance to the overall flavor of bourbon. From the quantification data some interesting trends were established that demonstrate some effects of barrel aging. OAVs are used as a gauge for potency and, generally, any …

Sensory directed determination of odor important components of natural (raw) and roasted pecan oil
… Following quantitation, odor activity values (OAVs) were calculated to determine the odor impact of the selected odorants. These results revealed 28 compounds with odor importance in RPO (OAV ≥ 1): 2,3-pentanedione, 2-acetyl-1-pyrroline, 2-methylpropanal, 3-methylbutanal, (E,Z)-2,4-decadienal, …

Evaluation of Flavor Variation in Swiss Cheese from Five Factories Using Selected Ion Flow Tube Mass Spectrometry (SIFT-MS), Descriptive Sensory Analysis, and Consumer Testing
… varying concentrations and odor activity values (OAV) of high impact volatile organic compounds (VOCs). OAVs (concentration/threshold) were utilized to discriminate all factories using Soft Independent Modeling of Class Analogy (SIMCA) indicating unique flavor profiles. A variety of variables …

Analysis of potent odorants in spearmint oils
… were used to calculate the odor activity value (OAV) of each compound by dividing the concentration by the odor detection threshold of the compound in water. Among the compounds quantified, those with the highest OAVs were R-(-)-carvone, 1,8-cineole, (E,Z)-2,6-nonadienal, β-damascenone, and …

Understanding the complex aroma chemistry of premium aged rums
… results were converted to odor activity values (OAVs) to gain a better understanding of the importance of the compounds to the overall aroma of the rum. Twenty-six compounds were found to have OAVs >1 in at least one rum. Fifteen compounds had OAVs >1 in all nine samples including …

Physicochemical and flavor characterization of Tupelo honey
… high concentration and odor-activity value (OAV) compared to other types of honeys and food products. (E)-β-Damascenone may be used as a marker compound to distinguish Tupelo honey from other unifloral honeys because of the uniquely high levels present in this honey.

Identification and characterization of potent odorants responsible for typical and storage-induced flavors of cola-flavored carbonated beverages
… analysis (SIDA), and their odor activity values (OAVs) were calculated as the ratios of their concentration to their odor detection thresholds in water. The OAV results, in which enantiomeric distribution was taken into account, revealed that 1,8-cineol, (R)-(-)-linalool, and octanal made the …

Identification and characterization of potent odorants in selected beet root (Beta vulgaris) products
… each individual compound, odor activity values (OAVs) were determined. OAVs were calculated by dividing the concentration of a compound by its odor threshold. An OAV provides an estimate of a compound’s odor potency and its potential importance to the overall aroma of the product. Of the 26 aroma …

Mass Properties Calculation and Fuel Analysis in the Conceptual Design of Uninhabited Air Vehicles
The determination of an aircraft's mass properties is critical during its conceptual design phase. Obtaining reliable mass property information early in the design of an aircraft can prevent design mistakes that can be extremely costly further along in the development process. In this thesis, …
