Phellandrene is a bicyclic monoterpene found in various essential oils, particularly from plants like coriander and ginger. It has a pleasant citrusy aroma and is used in flavoring and fragrance applications. Phellandrene exists in two isomeric forms, alpha and beta, with distinct sensory characteristics. In culinary contexts, it contributes to the flavor profile of spices and is noted for its potential health benefits, including antimicrobial properties. Its volatility makes it suitable for use in perfumery and as a flavoring agent in food products.
