Flavor is one of greatest joys; Flavor is created by the brain; Flavor is 80% determined by retronasal aroma.

Orthonasal and Retronasal olfaction

Orthonasal olfaction

Orthonasalstimulus delivery occurs when odorants travel inward from the anterior nares (nostrils) towards the olfactory mucosa
Orthonasalolfaction occurs during respiratory inhalation or sniffing;

Retronasal olfaction

Retronasalstimulation is caused by the ascent of odorants through the posterior nares of the nasopharynx
Retronasalolfaction occurs during respiratory exhalation or after swallowing.

Purpose:

Identify nutrition 

Hedonic

Since the brain needs a "hedonic" reaction to identify nutrition, the pleasant overall flavor is obligatory for food and beverage and has to be improved through the full-spectrum process.
