Cover Story: Essential oils (EOs) from Abies sachalinensis effectively remove nitrogen dioxide and possess antifungal activity. Underwater shockwaves generate an instantaneous high pressure that ruptures cell walls, enhancing the performance of steam distillation and oil extraction. The EO yield significantly increased with the number of shockwave cycles after applying. Pretreatment with shockwaves also reduced total energy consumption. Antioxidant activity increased by more than 30-fold in pretreated leaves compared to untreated dried leaves. This novel process can significantly reduce the energy used for EO extraction in steam distillation, thereby contributing to the development of a low-energy, sustainable EO production system.
