Flavor perception is an aggregation of auditory, taste, haptic, and smell sensory information. Retronasal smell plays the biggest role in the sensation of flavor. During the process of mastication, the tongue manipulates food to release odorants. These odorants enter the nasal cavity during exhalation. The smell of food has the sensation of being in the mouth because of co-activation of the motor cortex and olfactory epithelium during mastication.
