OVERVIEW OF MATERIALS AND TECHNIQUES FOR ENCAPSULATION OF NATURAL PRODUCTS: A MINI-REVIEW
AbstractIn the recent advancement of the food and pharmaceutical industry, the encapsulation process has gained interest in the production of functional food and the sustained release of drugs to the target site. The designing and the fabrication of micro or nanocapsule has become the active field of research over the few decades. Encapsulation increases the shelf life of the bioactive materials, increases their stability and protects the bio-actives from the harsh environment. Therefore, the encapsulation process has a great potentiality in the development of functional food and drugs. Many bioactive materials, oils, probiotics, and drugs are encapsulated in a microcapsule made up of varieties of polymeric and non-polymeric substances. Successful encapsulation of materials depends on the choice of the wall materials and the correct techniques adopted for the formation of the microsphere. In this review, an attempt has been made to discuss the different materials and the techniques used in the encapsulation process with reference to the food and pharmaceutical industry.
