Encapsulation of essential oils for the development of biosourced pesticides with controlled release: a review

peer reviewedEssential oil (EO) encapsulation can be carried out via a multitude of techniques depending on applications. Because of EOs biological activities, development of biosourced pesticides with EOs encapsulation is of great interest. A lot of methods had been developed; they are presented in this review together with the properties of the final products. Encapsulation conserves and protects EOs from outside aggression, but also allows for controlled release, which is useful for applications in agronomy. The focus is on matrices that are of interest for the controlled release of their content: alginate, chitosan and cyclodextrin. Those three matrices are used with several methods to create EOs encapsulation with different structures, capacities and release profiles.European Hub on New Challenges in the Field of Essentials Oils (EOHUB) project (600873-EPP-1-2018-1ES-EPPKA2-KA)
