The Pathway for Retronasal Airflow

The Pathway for Retronasal Airflow

(p.38) Chapter Four The Pathway for Retronasal Airflow

Gordon M. Shepherd

Columbia University Press

Breathing out produces its own complex retronasal airflow patterns in the nose. We show how humans are adapted for retronasal smell compared with the dog and other animals. The nose pinch test proves that much of flavor comes from retronasal smell. Research suggests that the flow path for retronasal smell is enhanced in humans. We discuss tips for wine tasting.

Keywords:   nasal valve, nasal cavity, nasopharynx, chromatographic theory, retronasal smell, nose pinch test
