Abstract:

The microencapsulation process is essentially creating a barrier within the core and its wall materials. Microencapsulation provides us the solution to encapsulate materials like food ingredients, enzymes, cells, marine and vegetable oil like micrometric scale materials. Microencapsulation has a special type of capacity to improve thermostability, oxidative stability, shelf-life, and sensitivity towards the core material's temp-pressure. The encapsulation process includes various methods like emulsion polymerization, ionic gelation, spray drying, centrifugal extrusion, extrusion, and thermal gelation. This article describes an introduction about microencapsulation, methods/techniques used for encapsulation of core material, types of polymer and carrier used with their special imparting properties and application; as this technology is majorly applied in polymer, pharmaceuticals, oleochemicals, agricultural, foods, and textile industries. The most recent development in this technology is related to improvement in the controlled release of encapsulation with various physical as well as chemical processing conditions. This article gives information about microencapsulation to scientists and industries who are interested in current encapsulation technology and trying to improve some methods.
