The main components and contents of each oil are obviously different. The main components of the steam distilled oil are monoterpenes and sesquiterpenes, the pungency components of ginger have not been found.Besides sesquiterpene, the other two oils contain mainly the pungency components, the total content is 18.61% in the cold pressed ginger oil, and 23.09% in the supercritical CO 2 extracted ginger oil, respectively. These two oils preserved the typical spicy odor and pungency of ginger.
