2-methylisoborneol

260 ng per capsule

Earthy, mouldy, like peat or compost”

Certified water flavour standard used to train professional tasters to recognize and scale the intensity of earthy character. 2-Methylisoborneol is formed by Cyanobacteria, Actinobacteria and algae in lakes, reservoirs and water distribution systems. It has a very low odour threshold and is one of the most common flavour faults in potable water. The compound imparts an unpleasant earthy note, reminiscent of peat or compost.

Methylisoborneol (2-MIB) is formed by Actinobacteria, Cyanobacteria and algae in lakes, reservoirs and water distribution systems. It is produced both by actively-growing organisms and through cell lysis and decomposition.
Importance
Methylisoborneol imparts an unpleasant earthy odour to water which is reminiscent of peat or rotting compost. It is extremely odour-active and for that reason is one of the most common flavour faults in potable water.
