The growth trends of the global market of essential oils and the demand for natural substances are the drivers of the spread of the use of essential oils in various sectors of the national economy. There are many methods of obtaining essential oils, the article describes and compares traditional and innovative methods that slow down the risk of losing the main thermolabile components of plant raw materials, preserve quality, reduce the extraction time, act environmentally safe and increase the percentage of essential oils yield. Due to the fact that traditional methods of obtaining essential oils have many disadvantages, the main one of which is the thermal stability of essential oils at high temperatures, there is a need for innovative methods that will reduce the influence of these factors. The article presents experimental data of experiments on different samples of lavender flowers and hyssop of the "Marquis" variety. An experimental stand for extracting essential oil from lavender and hyssop using an innovative method — microwave steam distillation — is illustrated. This process is a combination of traditional technologies, namely, steam distillation and innovative technology, microwave heating. Microwave heating helped initiate and create mass and heat transfer from within the plant matrices to the outside, resulting in a significant reduction in extraction time, with influence of mechano-diffusion. Based on the analysis of the methods and on the basis of experimental data, we conclude that electrodynamic systems have significant prospects for widespread use. Therefore, the task is to involve them in the processes of obtaining extracts of essential oils. The extraction kinetics and the influence of the hydromodule on the extraction process were studied. Cyclic extraction was found to extract more target components than single extraction. The influence of the hydromodule on the intensity of mass transfer characterizes the scientific and technical contradiction between the factors of increasing the value of the driving force and the concentration of the extract. The influence of the processing scheme on the intensity of mass transfer was considered using the example of "Marquis" type hyssop. The obtained results are the basis for the organization of energy-efficient modes of extraction from lavender and hyssop flowers. [ABSTRACT FROM AUTHOR]
