ABSTRACT
Encapsulation is the process of protecting, packing, entrapping, or immobilizing an active material such as a food ingredients, avorings, drug molecules, and chemical substances, in a solid, liquid, or gas state within a shielding material released at a controlled rate or immediately under specic conditions.1 Encapsulation is used in industries such as agriculture and food and pharmaceutical technologies. Encapsulation improves the stability of an incorporated substance against the environment, masking undesirable tastes, avors and colors, determining dosage, controlling the handling and release of active ingredients at specied sites.2 Several studies have proposed techniques to fabricate micro-and nanoparticles that act on their own or encapsulate active substances. The most extensively used technique to produce microspheres is an emulsion/evaporation-based method.3
