Whiskey lactone Usage And Synthesis

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.

Aroma threshold values

80% of a taste panel found whiskey lactone intolerable at 160 ppm

Taste threshold values

Taste characteristics at 0.5 ppm: woody, coumarinic, coconut, lactonic, creamy and nutty with a toasted nuance.

Trade name

Methyl octalactoneTM (PFW)
