A REVIEW ON MICROENCAPSULATION

Prof. Sharma Shubham*, Sharma Geetika and Jaiswal Silky

ABSTRACT

Microencapsulation is a process by which very tiny droplets or particles of liquid, solid or gas are enclosed or coated with a continuous film of polymeric material. It includes Bio encapsulation which is more restricted to the entrapment of a biologically active substance generally to improve its performance and to enhance its shelf life. This technique has been employed in a diverse range of fields from chemicals and pharmaceuticals to cosmetics and printing. For this reason, widespread interest has developed in microencapsulation technology. The most significant feature of microcapsules is their microscopic size that allows for a huge surface area. The large surface area is available for sites of adsorption and desorption, chemical reactions, light scattering, etc. This review paper highlights the major reasons behind microencapsulation, important techniques of microencapsulation and application of microencapsulated products in different areas of science and technology.
