Abstract: Encapsulation is a process in which tiny particles are surrounded by a coating in a homogeneous or heterogeneous matrix, to give small capsules. The substance that is encapsulated may be called the core material, the active agent, fill, internal phase, or payload phase. The substance that is encapsulating may be called the coating, membrane, shell, carrier material, wall material, external phase, or matrix. The carrier material of encapsulates used in food products or processes should be food grade and able to form a barrier for the active agent and its surroundings.

However, there are some challenges in the development of functional foods, particularly in which the direct use of some bioactives is involved. In this context, microencapsulation emerges as a potential approach to overcome these problems and, additionally, to provide controlled or targeted delivery or release. These factors, together with the lack of regu- Received 19th December , Accepted 7th February lation, in Europe and in the United States, delay the development of new functional foods and, conse- DOI:

Micro-encapsulation is defined as the technology for packaging with the help of protective membranes particles of finely ground solids, droplets of liquids or gaseous materials in small capsules that release their contents at controlled rates over prolonged periods of time under the influences of specific conditions Boh, The material encapsulating the core is referred to as coating or shell. The majority of microcapsules have spherical shapes and their diameter varies from a few microns to 1 mm. However, some authors consider particles of even more than one millimeter as microcapsules. For the purpose of this chapter the term microcapsule refers to capsules whose aim is the protection and controlled release of the active substance, and the term microsphere, a commonly used term in the scientific literature, refers to granules, that do not have a core-shell morphology, and can be simply defined as the embedding of an active substance in a matrix Watheley,

McClements, the capsules can be completely genetically-modified MCF7 cells with alternate layers of characterized before use.

These can vary from 6 mm to 6 meters diameter. Although the performance of the coating material in the pdr application is crucial, matching of the material to the process technology and process conditions is likely to be of equal importance, P. Carriazo.
