Abstract
Phosphorylated saccharide of the present invention includes at least one phosphate group in its molecule, selected from the group consisting of glucan, mannan, dextran, agar, cyclodextrin, fucoidan, gellan gum, Locust bean gum, guar gum, tamarind gum, and xanthan gum.
Claims12
A method for solubilizing alkaline earth metal or iron which comprises contacting a phosphorylated saccharide or a derivative of the phosphorylated saccharide bound to a protein or a peptide with an alkaline earth metal or iron containing compound, wherein the phosphorylated saccharide is a saccharide of which at least one hydroxy group is phosphorylated, and wherein the saccharide is selected from the group consisting of glucan, mannan, dextran, agar, cyclodextrin, fucoidan, gellan gum, Locust bean gum, guar gum, tamarind gum, and xanthan gum.
Feeds, foods, drinks, and food additive compositions comprising a phosphorylated saccharide or a derivative of the phosphorylated saccharide bound to a protein or a peptide and optionally also bound to an alkaline earth metal or iron, wherein the phosphorylated saccharide is a saccharide of which at least one hydroxy group is phosphorylated, and wherein the saccharide is selected from the group consisting of glucan, mannan, dextran, agar, cyclodextrin, fucoidan, gellan gum, Locust bean gum guar gum, tamarind gum, and xanthan gum.
A phosphorylated saccharide prepared by treating a starch having at least one phosphate group with one or more enzymes, wherein the phosphorylated saccharide is selected from the group consisting of glucan composed of 3 to 5 glucoses with .alpha.-1,4 linkages with one phosphate group being bound to the 3-position or the 6-position of a glucose residue within the glucan, and glucan composed of 2 to 8 glucoses with .alpha.-1,4 linkages with two or more phosphate groups being bound to the 3-position and/or the 6-position of glucose residues within the glucan.
A phosphorylated saccharide derivative comprised of a phosphorylated saccharide bound to a protein or peptide, wherein the phosphorylated saccharide is prepared by treating a starch with at least one phosphate group with one or more enzymes, and wherein the phosphorylated saccharide is selected from the group consisting of glucan composed of 3 to 5 glucoses with .alpha.-1,4 linkages with one phosphate group being bound to the glucan, and glucan composed of 2 to 8 glucoses with .alpha.-1,4 linkages with two or more phosphate groups being bound to the glucan.
A phosphorylated saccharide derivative comprised of a phosphorylated saccharide bound to an alkaline earth metal or iron, wherein the phosphorylated saccharide is prepared bv treating a starch with at least one phosphate group with one or more enzymes, and wherein the phosphorylated saccharide is selected from the group consisting of glucan composed of 3 to 5 glucoses with .alpha.-1,4 linkages with one phosphate group being bound to the glucan, and glucan composed of 2 to 8 glucoses with .alpha.-1,4 linkages with two or more phosphate groups being bound to the glucan.
