Analysis of potent odorants in spearmint oils
… there has been little research on the potent odorants in spearmint. The identification and quantitation of these compounds was performed in this study to give a better understanding the flavor chemistry of spearmint oils. Potent odorants in Native spearmint, Scotch spearmint, and Macho mint …

Encoding and Processing of Accessory Olfactory System Odorants
… as mating, aggression, and predator avoidance. Odorants are detected by sensory neurons in a specialized structure called the vomeronasal organ, and these neurons project to the accessory olfactory bulb. The accessory olfactory bulb is the first site of information integration and processing …

Identification and quantitation of predominant odorants in roasted chicory
… evaporation (SAFE). Identification of potent odorants was achieved by gas chromatography-olfactometry (GC-O) combined with aroma extract dilution analysis (AEDA) and gas chromatography-mass spectrometry (GC-MS). Forty-six compounds were quantitated by stable isotope dilution analysis (SIDA) …

Oxidation of Disinfection Byproducts and Algae-related Odorants by UV/H₂O₂
… and 2-methylisoborneol, which are earthy-musty odorants that commonly occur in drinking water. UV/H₂O₂ is an expensive advanced oxidation process that is used to successfully control geosmin and 2-methylisoborneol. The aqueous oxidation of odorous aldehydes and halogenated DPBs were compared to …

Identification and characterization of potent odorants in selected beet root (Beta vulgaris) products
… root was performed in the present study. Potent odorants were characterized by the use of aroma extract dilution analysis (AEDA) coupled with gas chromatography-olfactometry (GCO), as well as supported analytically by the use of gas chromatography-mass spectrometry (GC-MS). Initial analyses were …

Identification and characterization of potent odorants responsible for typical and storage-induced flavors of cola-flavored carbonated beverages
… reactions. Degradation of typical potent odorants and formation of storage-induced odorants by these reactions leading to flavor changes in cola-flavored carbonated beverages were evaluated in the present study. The potent odorants in the top three US brands of regular colas were …

Sensorial characteristics of odour active compounds from raw natural rubber
… research aims to improve our understanding on odorants behaviour across different variabilities of rubber including clonal, seasonal and pre-treatment variations. This will enable the rubber processing operators to develop better management strategies to control emissions, more effectively. …

Behavioral Response of Pacific Lamprey (Entosphenus tridentatus) to Predator Odors
… if Pacific lamprey respond to predator odorants may provide a management tool for use in conjunction with attractants in guiding lamprey to suitable spawning habitat and deterring them from poor habitat. Previous research has failed to explore Pacific lamprey response to predator …

Measuring and Developing a Control Strategy for Odorous Gases from Solids Handling Processes of a Large Wastewater Treatment Plant
… was applied to analyze several predetermined odorants. A carboxen-polydimethylsiloxane fiber was used for the analysis of an amine, and several sulfur compounds, and a polyacrylate fiber for the analysis of predetermined volatile fatty acids. Calibration curves were developed within the ranges …

Starved State Dependent Modulation of Olfactory Receptor Neuron Function in Drosophila melanogaster larvae
… regarding sensory neuron responses to food odorants and modulation of these responses by hunger, much less is known about the extent of modulation that exists among individual sensory neurons and its impact on driving behavioral output. We hypothesized that starvation differentially alters …

Aroma characterization of American rye whiskey by chemical and sensory assays
… in recent years, the aroma profile and potent odorants of American rye whiskey have not been reported. Two dilution analysis methods for Gas Chromatography-Olfactometry (GCO) were used to identify the potent odorants in rye whiskey: Sample Dilution Analysis (SDA) – a novel, nonextractive, …

Olfactory identification, detection thresholds, and sensitivity in kidney disease patients
… diagnosed with Kidney Disease for numerous odorants. No significant differences were found in olfactory identification, detection thresholds, or sensitivity compared to healthy controls. Despite the non-significant results, there did appear a trend of poorer olfactory abilities in Kidney …

A Novel Role for Odorant Binding Proteins in Deactivation of Drosophila Olfactory Neurons
… a striking deactivation defect to a subset of odorants. Surprisingly, other odorants detected by the same receptor are differentially affected by the absence of OS-E and OS-F, revealing an odorant-specific role for these OBPs in deactivation kinetics. Activation kinetics remain normal for the …

Averaged Evoked Responses to Light and Odorant Under Certain and Uncertain Conditions
… To determine if the averaged evoked response to odorants was similar to the late positive component in the averaged evoked response to lights, both light and odorant were presented under two conditions to see if they would both occur under the same experimental condition and both be absent under …

Olfactory working memory: the role of perceived odor name-ability
… in working memory. Participants smelled odorants through the left or right nostril or with both nostrils and then provided an identifying label for each odor and rated how accurately their label represented the odor. After a short delay, the participants were given a new stimulus set …

Mosquito odor receptor gene targets to alter vector host choice
… receptors, each of which interact with specific odorants. Differences in feeding behaviors have significant consequences for the vectorial capacity of Anopheles mosquitoes. Mosquitoes in the genus Anopheles vector the pathogens causing human malaria, which resulted in over 600,000 deaths in 2020 …

Identification of compounds responsible for the characteristic “soy sauce” flavor of traditional Chinese liquor
… aims to identify the key and characterizing odorants in soy sauce aroma liquor in the case of MT. Through the use of advanced separation and analytical methods, 143 odor-active components were detected. The relative potencies of the odorants were assessed by gas chromatography-olfactometry …
