Abstract: The present invention relates to a process for producing a water-absorbent polysaccharide including the process steps of bringing into contact an uncrosslinked polysaccharide with a polyphosphate or a polyphosphoric acid as crosslinking agent in the presence of water to form a polysaccharide gel and crosslinking the polysaccharide gel. The invention further relates to a water-absorbent polysaccharide obtainable by this process, a water-absorbent polysaccharide, a composite, a process for producing a composite, a composite produced by this process, the use of the water-absorbent polysaccharides or of the composites as well as the use of polyphosphates.
