Encapsulation of herb extracts (Aromatic and medicinal herbs)

Biologically active compounds from aromatic and medicinal herbs are relatively unstable, have strong odors, can have low water solubility, and degrade quickly during the processing and storage. Encapsulation technology offers protection, controlled and targeted release of encapsulated biologically active compounds. Nanoencapsulation technology is always evolving, providing thus new methodology in preparation and application of delivery systems loaded with bioactive compounds. This review aims to summarize the most important information for the encapsulation of natural extracts using alternative technologies. We highlight the importance of the implementation of prepared nanomaterials loaded with bioactive compounds from herb extracts into real food. Furthermore, we highlight novel technologies that offer new capabilities like, for example, nanotubes or nanofibers may because of their high surface to volume ratio allow achieving desirable actions. Furthermore, nanocrystals offer unique capabilities to overcome problems regarding the poor solubility of compounds and even to increase the antioxidant properties of entrapped compounds. These types of nanosystems may be tailored to either act on the spot or with the delayed release of active compounds, whilst protecting the encapsulated biologically active compounds.
