Abstract

The current invention is directed toward substantially water resistant expanded polysaccharide compositions. The expanded polysaccharide compositions comprise a polysaccharide derivative having a degree of substitution between about 1.5 and about 3.0, and preferably, a nucleating agent and a filler. The addition of the nucleating agent and filler result in an expanded polysaccharide composition with a dramatically improved texture. The invention also relates to processes for producing the expanded polysaccharide composition.
