Whiskey lactone Chemical Properties,Usage,Production

Chemical Properties

Whiskey Lactone is found as its cis- and trans-isomers in whiskey and in oakwood volatiles; the cis-isomer is the more important in sensory terms. It is a clear, almost colorless liquid with an intense, warm, sweet, coumarin-like odor.
A cis–trans mixture can be prepared by radical addition reaction of pentanal with crotonic acid followed by reductive cyclization of the resulting ??-oxo acid with sodium boron hydride/sulfuric acid . It is used in aroma compositions, for example, for beverages.

Occurrence

Reported present in cognac, rum, Irish malt, bourbon whiskey, scotch, sherry, port and wine.

Uses

flavors and fragrances

Definition
