Abstract
Disclosed is an absorbent structure comprising a microbial polysaccharide having improved porosity and a process of making the same. The absorbent structure may be adapted for use in an absorbent product such as a diaper or incontinence product. The process involves the supercritical drying of a microbial polysaccharide to remove at least a portion of the aqueous medium in which the microbial polysaccharide is produced without unacceptably reducing the porosity of the microbial polysaccharide.
