Geosmin MSDS

The odor of Geosmin is best described as the smell of the air after rain falls on dry soil. Geosmin is responsible for the muddy smell in many commercially important freshwater fish. Geosmin combines with 2-methylisoborneol (MIB).
Human’s can smell concentrations as low as 10 parts per trillion of Geosmin in water. The characteristic odor of soil was first investigated by Berthelot in 1891. In 1965 the structure of the responsible compound geosmin was determined by Gerber. It was not until 1981 that the pathways for the biosynthesis of these compounds determined.*

I don’t know about you, but I learn something new every day.  There is so much to know about flavors & fragrances & their ingredients that I am compelled to share, especially when the information involves very commonly used materials.

In this case, I have stumbled upon THE CITRUS PAGES.

This is a non-commercial, comprehensively- illustrated citrus website with descriptions and uses of over 400 varieties of citrus.  Enjoy!
