Occurrence

Reported found in butterfat, Swiss, blue, cheddar, Romano, and Parmesan cheeses and goat, sheep and other cheeses, mutton, hop oil, beer, white and red wine.

Uses

9-Decenoic Acid is used to prepare epothilones A and B via macroaldolization, olefin metathesis and macrolactonization. It is also used to synthesize potent, selective, and efficacious reversible α-ketoheterocycle inhibitors of fatty acid amide hydrolase effective as analgesics.

Definition

ChEBI: A decenoic acid having the double bond at position 9.

Taste threshold values

Taste characteristics at 40 ppm: waxy, creamy, fatty with a cheesy and milky nuance.
