ABSTRACT:
Amylase treated granular starches provide a microporous matrix material adapted for absorption and releasable containment of functional compositions. The microporous starch granules are chemically derivatized to enhance absorptive and structural properties. Absorbed functional substances are released from the microporous starch matrix under the influence of mechanical compression, by diffusion into a surrounding fluid or as a result of degradation of the granular starch matrix.
