## 4 Conclusions  
The approach investigated in this work represents the sustainable aroma stabilization process, which ensures the efficient attainment of aroma compounds and their preservation, consequently reducing costs, promoting a more rational use of natural resources, and reducing waste generation. Also, the goals of this work correspond to the objectives of green chemistry and the Sustainable Development Goals agenda, as they include environmental and economic sustainability, environmental protection, and human well-being. By comparison, between the changes in the headspace profiles of the control and CO2-NADES systems, it is evident that the application of NADES advanced the stability of _S. montana_ volatile compounds. Apart from the more pronounced changes with regard to oxidation and other transformational reactions, the formation of non-terpene components such as acetic acid, E,E-hepta-2,4-dienal, and \(\gamma\)-butyrolactone was observed in the control. Moreover, these components can significantly reduce the quality of the products. In CO\({}_{2}\)-NADES systems, there was no formation of these components, and the changes in the headspace profiles were less pronounced compared to the control. Bet/EG was observed as a system with the lowest oscillations over time. In addition, using the Wilcoxon test, it was established that the systems with the least changes were Bet/EG, Gly/Glu, and Bet/Sor/W. It is of great importance to continue the study of aroma compounds from different types of materials and their interactions with different NADES because the stabilities of volatile components, essential oils, extracts, and other products containing volatile aroma compounds depend on the characteristics of those components and their tendencies to oxidation and degradation changes.
