ABSTRACT:
Virtually any material may be encapsulated in a starch matrix by combining the material with a high temperature-stabilized dispersion of starch, optionally in the presence of salt. The temperature-stabilized starch dispersion acts as a protective colloid, encasing the material to be encapsulated. Upon subsequent rapid cooling of this mixture on a chilled surface the starch polymer chains collapse upon themselves, forming a firm sheet or the like and encapsulating the core material. The sheet can then be cut, chopped or sliced in the wet state, then dried and ground to yield particles.
