Dihydrocarveol is a liquid with a floral-minty smell. This is a monocyclic monoterpene - alcohol . It is found in cumin , pepper , celery and mint . In water , it is insoluble in ethanol , however, readily soluble. The flash point of the liquid is 93.8 ° C. It is a monohydric secondary alcohol because one hydroxy group is attached to one carbon atom, which in turn is attached to two carbon atoms.

Extraction and presentation

A recombinant lacer enoate reductase from Lactobacillus casei catalyzes the reduction of ( R ) - carvone and ( S ) -carvone to (2 R , 5 R ) - dihydrocarvone and (2 R , 5 S ) -Dihydrocarvon, by a carbonyl reductase from Sporobolomyces salmonicolor SSCR or Candida magnolia CMCR were further reduced to dihydrocarveoli.
