| Research Abstract |
Gellous biomass containing cellulose is produced from plant seeds and chemical structure of its constituent polysaccharides, thermal stability, rheological property were analyzed. The results indicate the importance of acidic xylan to attach on the surface of cellulose. Electrostatic repulsions between carboxyl groups due to uronic acids took major role in formation of gels. Importance of divalent metals and hydrogen bonds for formation of gellous structure was also shown. Inaddition, degree of substitution by uronic acid in the main chain of xylan was abnormally as high as one uronic acid per about two xylopyranosyl residues.
