Spanish and Portuguese names for flavour; see there.

The sense of taste (also gustatory from Latin gustare = to taste, to savour) serves to control the ingested food. Like smell, it is one of the chemical senses. In a broader sense, the sensation of taste is a complex interaction of the gustatory (tasting) sense of taste and the olfactory (smelling) sense of smell. This is further complemented with tactile or trigeminal tactile, pain and temperature information from the oral cavity. The latter includes, for example, the sensations of sharp (hot) and astringent (effect of tannin-rich red wines, which should not be confused with bitter). In a narrower sense, however, taste consists of relatively few different tastes absorbed via the tongue and partly also via the pharyngeal mucosa.

Zunge mit den Geschmacksrichtungen und Rezeptoren

For a long time, only four tastes were known, namely bitter, salty, acid and sweet. In the 1990s, umami (also meaty, savoury, savoury) was defined and scientifically recognised as the fifth taste. Finally, in 2011, the existence of receptors for fat and thus fatty as a possible sixth flavour was established in humans. Other possible taste qualities under discussion are "water" (tastes "like nothing" in pure form), metallic and alkaline. The perception of a flavour substance depends differently on the quantity depending on the substance and is called the perception threshold (limit).
