Why Nose-clipping Works

(1/3) > >>

Seth Roberts:
Nose-clipping eliminates the flavor of foods because it eliminates "retronasal stimulation":


--- Quote ---Retronasal stimulation occurs during food ingestion, when volatile molecules released from the food in the mouth are pumped, by movements of the mouth, from the back of the oral cavity up through the nasopharynx to the olfactory epithelium. Orthonasal olfaction does not contribute to this sensation. Retronasal olfactory stimulation can be studied by introducing odour stimuli at the back of the mouth20 or by their release from ingested foods21. Marcel Proust vividly described how a tea-soaked madeleine brought back powerful childhood memories22, and this would have occurred primarily through the retronasal pathway. It is activated only when breathing out through the nose between mastications or swallowings23 (Fig. 2b). Because the molecules arise from the food in the mouth, they are referred to the mouth; that is, they are perceived as if they are sensed within the mouth24. This retronasal food-molecule-laden air is judged to be part of the 'taste' of the food25 and has been shown to be necessary for flavour identification26. Thus, although a large part of flavour is due to smell, it is attributed to 'taste', and is therefore almost entirely hidden from our conscious perception.

Cool. Even knowing that most of taste is really smell, I was astonished by noseclipping. You don't believe it until you experience it.

Seth Roberts:
it gets easier with practice, I've found. Sort of turns into brushing your teeth.

What is amazing is the amount of flavor I notice immediately after noseclipping.

flavor from the food you ate while nose-clipped? or from other foods?
