Abstract: In the paper, the rheological properties of Grateloupia filicina polysacocharide extracted in cold water or hot water were discussed comparatively. The results showed that the extraction rate of coarse polysaccharide of Grateloupia filicina extracted in cold water is higher than that extracted in hot-water. Grateloupia filicina polysaccharide dissolved in both cold water and hot water shows favorable rheological properties, but the rheological property of the cold water dissolved section excells that of the hot water dissolved section.

Key words: Grateloupia filicna (Wulf.) C.Agardh, polysaccharide, rheological property, dissolved in cold water section and in hot water section
