Microencapsulation
8/15/2008
Micro-encapsulation is a process in which tiny particles or droplets are
surrounded by a coating to give small capsules many useful properties. In a
relatively simplistic form, a microcapsule is a small sphere with a uniform wall
around it. The material inside the microcapsule is referred to as the core,
internal phase, or fill, whereas the wall is sometimes called a shell, coating,
or membrane. Most microcapsules have diameters between a few micrometers and a
few millimeters.

Notes
The definition has been expanded, and includes most foods. Every class of
food ingredient has been encapsulated; flavors are the most common. The
technique of microencapsulation depends on the physical and chemical properties
of the material to be encapsulated.

Many microcapsules however bear little resemblance to these simple spheres.
The core may be a crystal, a jagged adsorbent particle, an emulsion, a
suspension of solids, or a suspension of smaller microcapsules. The microcapsule
even may have multiple walls.
