The above-mentioned techniques are widely used for microencapsulation of several pharmaceuticals. Among these techniques, fluidized bed or air suspension method, coacervation and phase separation, spray- drying and spray-congealing, pan coating and solvent evaporation methods are widely used.

What is the most common method of microencapsulation?

The spray drying technique is the most common microencapsulation method, has been used for decades to encapsulate mainly flavors, lipids, and pigments, but its use in thermo-sensitive products, such as microorganisms and essential oils, can be limited because the required high temperature causes volatilization and/or ...

Which is the physical method of microencapsulation?

Spinning disk, also termed rotational suspension separation, is another physical technique for microencapsulation. A mixture is formed with the material for the internal core of the microcapsule and the liquid microcapsule coating material.
