Summary

Essential oils (EOs) are valuable products due to their application in several industry segments, such as pharmaceutical and medical. Considering their importance, their scarcity, and the importance of their application, an efficient extraction method is necessary for their recovery from plants, preserving their properties, such as antioxidant and antimicrobial nature. In this context, alternative extraction methods encounter advantages, for preserving thermo-labile compounds and for being eco-friendly, especially supercritical fluid extraction with CO ₂ . This extraction method is advantageous due to its “green” characteristic and milder temperature conditions, but also for enabling selectivity and efficiency due to the supercritical fluid characteristics. Based on this, this chapter brings the advantages of the mentioned method, its typical behavior with proposals of performing mathematical modeling to the process, and the main variables studied by researchers and how they influence the EOs extraction process with literature examples. Throughout the chapter, the efficiency and the potential of SFE technology will be evident, being a great alternative to obtain purer extracts with bioactive characteristics.
