GAMMA TERPINENE – citrus, spicy and fresh note with hints of lemon, coriander and citrus zest

It has a tart, sweet, citrusy aroma, with hints of tropical fruit and lime. It is widely used as a flavoring to restore and enhance citrus oils. It has a refreshing, herbal, and citrus scent, not as lemony as the alpha isomer, but slightly warmer, with the same low lingering power.
The taste is slightly bitter and herbaceous, but becomes pleasant and citrusy at concentrations below 40 parts per million. This monoterpene has been used in the creation of some essential oils, primarily to impart flavor to peppermint, thyme, oregano, and other herbs. It oxidizes easily to the less desirable para-cymene. However, para-cymene is used to soften the top notes.
Gamma-terpinene is extracted from the essential oil of Lantana camara, a plant that grows abundantly in the Caribbean, South America, the southern Pacific, the Indian Ocean, and many other tropical and subtropical regions. This plant produces an essential oil similar to lavender-sage, but greener and more pungent, though overall very pleasant. The oil is produced in Haiti, but not on a regular basis.
There are three forms of terpinene: alpha, beta, and gamma. The beta isomer is not used in perfumery. Alpha-terpinene has a refreshing, lemony citrus scent with a short lingering aftertaste. The flavor is primarily lemony at concentrations below 40 parts per million, but becomes bitter at higher concentrations. The name "terpinene" has become popular in the trade, primarily to make it accessible to those interested in producing artificial essential oils. It has been used in artificial lemon oil, peppermint oil, and in small quantities in other essential oils, primarily for flavoring. Alpha-terpinene is extracted from the terpene fraction of sweet oranges, American turpentine oil, and various other methods.
