(+)-DIHYDROCARVONE

p-Menth-8-en-2-one has an herbaceous, spearmint-like odor.

Reported present in oregano oil, celery, spearmint oil, scotch spearmint oil, thymus, dill herb and seed and caraway seed.

The dual, herbal-minty quality of this compound will add an interesting twist to mint flavors as well as to celery, caraway, dill and herbal flavors, especially intended for cough drops and oral care products. At very low levels, it will add depth to tropical flavors like lychee, guava, passion fruit and rambutan.

The N-functionalization of dihydrocarvone forms imine derivatives, which are synthons for preparing N-heterocycles.

ChEBI: A dihydrocarvone resulting from reduction of the endocyclic cyclohexene double bond.

The production of cis-Dihydrocarvone: 1) by Isomerization of Limonene oxide. 2) from Dihydrocarveol by oxidation - or 3) from Carvone by reduction.

Detection: 820 ppb to 1.06 ppm
