Process of Encapsulation and Microencapsulation
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.
Process of Encapsulation and Microencapsulation
Why Encapsulation?
To enhance the stability of active substancesImprove solubility and thereby increase its bio-availabilityTo ensure control release action of the core at the right time and with the right amountProtect sensitive substances from degradationPrevent the undesirable interactions of the active substance with other ingredientsConvert liquid active ingredient into powder formMasks unwanted taste, flavour and odourEnsure dust free operationImprove blending propertiesImprove flowability
