7. Conclusion and outlook

Traditional solid-liquid extraction and steam stripping technologies, some of which are centuries old, have demonstrated their effectiveness, but also their limitations in terms of productivity, profitability and extract quality. The need to overcome these limitations has led to the emergence of new technologies, including microwave-assisted extraction processes.

Historically, the first exploratory phase consisted in assessing the potential of microwaves in the field of extraction, as they had long been used industrially for cooking, defrosting and drying. The first applications tested were treatments carried out prior to extraction (drying, enzymatic inactivation). The potential of microwaves was then tested in the field of extraction itself, whether in the presence or absence of solvent. This first phase showed that microwaves dramatically accelerate extraction...
