Metabolite Identification
Common NameGeosmin
DescriptionGeosmin is found in corn. Implicated in off-flavour of shellfish, freshwater fish, drinking water and some vegetables.Geosmin, which literally translates to "earth smell", is an organic compound with a distinct earthy flavour and aroma, and is responsible for the earthy taste of beets and a contributor to the strong scent that occurs in the air when rain falls after a dry spell of weather (petrichor) or when soil is disturbed. The human nose is extremely sensitive to geosmin and is able to detect it at concentrations as low as 5 parts per trillion.
