Définition

  • Although there are individual differences in the extent to which we are sensitive to all taste qualities, such variation is most pronounced for bitterness. Human responses to bitter thiourea compounds, in particular phenylthiocarbamide (PTC) and 6-n-propylthiouracil (PROP), have been extensively studied for several decades, and it is well established that 25 to 30% of Caucasian populations are highly insensitive to their taste (non-tasters), although this proportion does vary across cultures.
