Flavor is one of the main drivers of food consumption and acceptability. It is associated with pleasurable feelings during eating. Flavor is a multimodal perception corresponding to the functional integration of information from the chemical senses: olfaction, gustation, and nasal and oral somatosensory inputs.
As a result, astringency, as a sensation mediated by the trigeminal nerves, influences food flavor. Despite the importance of astringency in food consumer acceptance, the exact chemosensory mechanism of its detection and the nature of the receptors activated remain unknown.
After reviewing the current hypotheses on the molecular origin of astringency, this study developed a ground-breaking hypothesis on the molecular mechanisms underpinning this sensation as a perspective for future research.
