Abstract
Abstract The present invention is a saccharide-based matrix, and the products resulting therefrom, made from a maltodextrin feedstock subjected to conditions which induce flash flow of the maltodextrin so that the matrix possesses a physically or chemically altered structure from the feedstock. The present invention also includes a method of producing the matrix and of making products which take advantage of the unique properties of the matrix.
