Microencapsulation is a process by which we apply a protective coating called a matrix around a small particle called the core or active. The matrix keeps an active ingredient locked in and stabilized until the release of the material is desired. People might encapsulate in order to mask a bitter or bad taste. An ingredient could be encapsulated in order to provide a barrier from other ingredients. An ingredient might be encapsulated to provide a specific temperature release (as in a baking application), a pH release, or a sustained or modified release.
