Essential oil (EO) encapsulation can be carried out via a multitude of techniques, depending on applications. Because of EOs' biological activities, the development of biosourced pesticides with EO encapsulation is of great interest. A lot of methods have 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 the matrices that are of interest for the controlled release of their content, namely: alginate, chitosan, and cyclodextrin. Those three matrices are used with several methods in order to create EO encapsulation with different structures, capacities, and release profiles.
精油（EO）的封装可以通过多种技术来实现，具体取决于应用。由于 EO 具有生物活性，因此开发具有 EO 封装的生物源农药具有重要意义。已经开发出了很多方法；本文综述了这些方法，并介绍了最终产品的性能。封装可以保护精油免受外界侵害，同时还可以实现控制释放，这对于农业应用非常有用。本文重点介绍了三种对于控制其内容物释放具有重要意义的基质，即：海藻酸钠、壳聚糖和环糊精。这三种基质可以通过多种方法结合使用，以创建具有不同结构、容量和释放特性的 EO 封装。
