Without intending to be limited to any particular theory, conventional methods to obtain extracts, such as, for example, essential oils from plant biomass frequently require the use of solvents that may be harmful to the environment, and/or humans. Furthermore, conventional methods frequently require large volumes of solvent to achieve acceptable yields of the extract. While microwave assisted extraction may overcome some of the limitations of conventional extraction methods, microwave assisted methods of obtaining extracts, such as, essential oils from plant biomass has had limited commercial development. Problems encountered in scaling up microwave assisted extraction methods up to an industrial scale include, for example, consistently obtaining extracts from a large volume of plant biomass. Additionally, the olfactive properties of the extract are frequently altered by the extraction process. Alterations may be caused by several factors, including, but not limited to the presence, or enrichment of compounds having undesirable olfactive notes. Other alterations may be the absence, or reduction of compounds having the desired olfactive notes.
Consequently, there is a need for microwave assisted extraction methods at an industrial scale that are capable of generating an extract, such as an essential oil with improved olfactive properties.
