James Eden, Ralph Trksak, Robert Williams: Starch based encapsulation process. National Starch and Chemical Corporation, Ellen T Dec, Edwin M Szala, March 14, 1989: US04812445 (48 worldwide citation)

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. Up ...
