Phenethyl isovalerate has a fruity (rose-like) odor and a bittersweet flavor, reminiscent of peach. It is not very stable.
Occurrence
Reported found in peppermint oil, spearmint oil, Scotch spearmint oil, beer, grape brandy, cognac, cider and lamb’s lettuce.
Preparation
By esterification of phenethyl alcohol with isovaleric acid.
Taste threshold values
Taste characteristics at 2 to 10 ppm: sweet, fruity, ripe pineapple with honey, berry and peachy nuances.
Flammability and Explosibility
Non flammable
Safety Profile
Mddly toxic by ingestion. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS
Synthesis
FEMA 2871 is prepared by azeotropic esteritication of Phenylethylalcohol with iso-Valerie acid.
