ChEBI: One of a pair of phellandrene cyclic monoterpene double-bond isomers in which both double bonds are endocyclic (cf. alpha-phellandrene, where one of them is exocyclic).

Aroma threshold values

Detection: 40 to 200 ppb

Taste threshold values

Taste characteristics at 20 ppm: terpenic, citrus-lime with a fresh green note.
