A New Classification of Perceptual Interactions between Odorants to Interpret Complex Aroma Systems. Application to Model Wine Aroma

Foods, 2021
Although perceptual interactions are usually mentioned and blamed for the difficulties in understanding the relationship between odorant composition and aromatic sensory properties, they are poorly defined and categorised.

Developmental Switch From Elemental to Configural Processing of Odor Mixtures in Humans. [PDF]

Dev Psychobiol
ABSTRACT Human perceptual abilities evolve throughout development, particularly with regard to processing complex stimuli. While many studies have investigated age‐related changes in olfactory sensitivity, none have examined how developmental stages influence the perception of odor mixtures at the elemental and configural levels.

Bitter Odorants and Odorous Bitters: Toxicity and Human TAS2R Targets

, 2023
International audienceFlavor is perceived through the olfactory, taste, and trigeminal systems, mediated by designated GPCRs and channels. Signal integration occurs mainly in the brain, but some cross-reactivities occur at the receptor level.

Important Odorants of Four Brassicaceae Species, and Discrepancies between Glucosinolate Profiles and Observed Hydrolysis Products

Foods, 2021
It is widely accepted that the distinctive aroma and flavour traits of Brassicaceae crops are produced by glucosinolate (GSL) hydrolysis products (GHPs) with other non-GSL derived compounds also reported to contribute significantly to their aromas.
