(57) Abstract: A novel food material having a calcium absorption promoting effect obtained by introducing a phosphate group into a water-soluble polysaccharide, and a method for producing the same. SOLUTION: A water-soluble phosphate polysaccharide is obtained by dissolving a water-soluble polysaccharide in water and boiling it, and then reacting it with an inorganic phosphate under alkaline conditions. The resulting water-soluble phosphorylated polysaccharide inhibits calcium salt precipitate formation in vitro, Promotes calcium absorption in the intestinal tract. |
