Plant essential oil terpenoid removal process method and application thereof

The invention discloses a plant essential oil terpene-removing process method which comprises the following steps: mixing essential oil with an adsorbent, and performing supercritical CO2 extraction and adsorbent desorption to obtain terpene-removed plant essential oil. The process is simple and feasible, large-scale production is easy, the adsorbent can be repeatedly used, the terpene removal effect is obvious, the adsorbent-supercritical CO2 terpene removal method is a green process, after terpene removal, the fresh ginger essential oil keeps the fragrance of the fresh ginger essential oil, meanwhile, the apparent quality of the fresh ginger essential oil does not change in the room-temperature sheltering storage process, and the terpene removal effect is good. The phenomena of darkening, turbidity, layering and the like are difficult to occur, further application of the ginger essential oil is facilitated, and the technical process route is also suitable for the terpene removal process of other plant essen
