FOOD MATERIAL FOR IRON SUPPLEMENT AND IRON-CONJUGATED PROTEIN AND/OR IRON-CONJUGATED POLYSACCHARIDE PROTEIN, AND THEIR PRODUCTION

摘要

PROBLEM TO BE SOLVED: To obtain a food material for iron supplement having no toxicity and no problem in its processability, excellent in taste and flavor, high in safety and also capable of easily taking iron ingredients because of being rich in hem-type iron ingredients of high absorbability, to obtain an iron-rich iron-conjugated protein, and to obtain an iron-rich iron-conjugated polysaccharide protein. SOLUTION: This food material for iron supplement is such one as to comprise at least one kind of basidiomycete selected from the genuses Lentinus, Glifora and Agaricus and contain >=0.5 g of iron ingredients in 100 g of the basidiomycete. The second objective iron-rich iron-conjugated protein and the third objective iron-rich iron-conjugated polysaccharide protein are such ones as to contain >=5 g of iron ingredients in 100 g of the iron-conjugated protein and iron-conjugated polysaccharide protein respectively. A method for producing this food material for iron supplement comprises cultivating at least one kind of basidiomycete selected from the respective genuses mentioned above in a culture medium containing water-soluble iron ingredients to let the basidiomycete assimilate iron ingredients to include iron ingredients in high concentrations in the protein and polysaccharide protein in the basidiomycete cell component and/or extracellular component.
