Fenchyl alcohol has a camphor-like odor with citrus notes and a bitter, lime-like favor.

Occurrence

Both the α- and the β-fenchyl alcohols are reported found in nature; in mixture, they are present in the essential oils of Picea alba, Pinus silvestris, pine oil, Artemisia santolinaefolia, and others; the isofenchyl alcohol (1,5,5-trimethyl-2-norbor- nanol) is not found in nature Reported found in citrus peel oils, grape, grape brandy, hop oil, nutmeg, rosemary, pepper, beer, tea, Ocimum basilicum, cognac, fennel and eucalyptus oil

Uses

Fenchol is a hop-derived aroma compound commonly found in beer.

Preparation

By reduction of fenchone or from pine terpenes.

Aroma threshold values

Taste threshold values

Taste characteristics at 1 to 5 ppm: intense camphoraceous, cooling, piney with an earthy nuance It has minty-citrus lime and spicy notes.

Purification Methods

It is prepared by reduction of (-)-fenchone and is purified by recrystallisation from *C6H6/pet ether, or distillation, or
