Encapsulation technology is a process of entrapping a core material (Active substance) within a secondary material that protects it from the environment and that can deliver the active substance to a specific site.
The Core material: Specific material to be coated which can be solid, liquid or gaseous or hydrophilic or hydrophobic.
The Protective material: Act as a carrier for core active substance and it is used for its stabilization from environmental effects.
Microencapsulation involves coating an active substance with a polymetri material and forming a microencapsulated product (Microparticles, microcapsules and microspheres) having diameter between 1 to 1000 μm.
