In order to integrate the target compounds into the final product, it is necessary to encapsulate them. The encapsulation of isolated substances will take place through the electrohydrodynamic process and spray drying. The first technique is a modern innovative method, which has recently been applied in industry and offers a variety of advantages:

(1) Micro- and Nano- inclusion of bioactive substances in nanoins and nanocapsules.

(2) No toxic solvents are required.

(3) Only small amounts of water or ethanol are needed.

In addition, spray drying is one of the most widely used encapsulation techniques, as it is flexible, continuous and involves low processing costs. The technique of electro-hydrodynamic process has two main advantages over spray-drying encapsulation: The process takes place at room temperature ensuring the quality and stability of the heat-sensitive components and is applied in the absence of any solvent. Biodegradable proteins and / or polysaccharide mixture are recommended as motherboards for the encapsulation of target compounds.
