###### Abstract  
The aim of this work was to establish the potential of natural deep eutectic solvents (NADES) for the stabilization of aroma volatile organic compounds from a natural source. _Satureja montana_ was used as a source of volatile components, as it is rich in terpenes of great commercial and biological importance, such as carvacrol, thymol, and thymoquinone, among others. Supercritical CO\({}_{2}\) was used to extract the lipophilic fraction of _S. montana_, which was further directly dispersed in NADES. The stabilizing capacity of seven different NADES based on betaine and glycerol was analyzed. The stability of the components in NADES was monitored by analyzing the headspace profile during 6 months of storage at room temperature. The changes in the headspace profile over time were analyzed by using different statistical and chemometric tools and the Wilcoxon matched pair test. It was determined that alterations over time occurred such as degradation and oxidation, and they were the most prominent in the control. In addition, the indicator of decreased stability of the control was the formation of the new compounds that could compromise the quality of the product. In the stabilized NADES samples, the changes were significantly less prominent, indicating that the NADES had a stabilizing effect on the volatile compounds. According to Wilcoxon matched pair test, the most efficient stability was achieved by using betaine/ethylene glycol, glycerol/glucose, and betaine/sorbitol/water. Therefore, by applying two green solvents, a sustainable approach for obtaining pure and high-quality _S. montana_ extracts with extended stability at room temperature was established. volatile compounds; _Satureja montana_; deep eutectic solvent; aromas; stabilization; supercritical carbon dioxide 202313112611 July 20  
the growth of green consumerism, represent the reason for the growing global demand for natural aroma compounds, their implementation in products, and the cessation and/or reduction in the use of their synthetic counterparts [1]. Therefore, the growing demand and wide applicability of aroma compounds pose new challenges and require new trends in production. Conventional production procedures, such as hydrodistillation and extraction with organic solvents that are harmful to human health and the environment, cannot ensure the rational use of natural raw materials and a high-quality and safe product in adequate quantities in an environmentally benign production process. Additionally, aroma compounds are characterized by instabilities, easy reactivities, volatilities, and tendencies to degradation; therefore, their application is difficult [3]. Apart from organoleptic alterations and impairment of the compounds' biological properties, is it also possible to compromise the consumers' well-being, for example, by manifesting skin-sensitizing effects [3]. In order to prevent the deterioration of the quality and biological properties, it is necessary to ensure the stability of aroma compounds during the process of isolation, processing, and storage. Furthermore, addressing the mentioned challenges is in accordance with the sustainable development agenda [4], as well as with the objectives of green chemistry, as it involves the creation of strategies that include the efficient use of natural renewable resources, attainment of long-term stable aroma compounds, elimination of the use of harmful solvents, waste reduction, and greater process efficiency. For aroma preservation, the most industrially relevant and represented technique is spray drying. However, this technology implies high process temperatures, which can be a huge disadvantage for thermosensitive components. Also, numerous techniques have been developed for the preservation of aroma volatile compounds such as fluidized bed coating, freeze-drying, spray cooling and spray chilling, extrusion, co-crystallization, simple or complex coacervation, inclusion complexation, ionic gelation, the formation of liposomes, etc. [5; 6].
