PROBLEM TO BE SOLVED: To obtain a food material for zinc supplement having no toxicity, excellent in gustatoriness and flavor, high in safety, having no problem in its processability and containing chelate-type zinc ingredients of high absorbability in high concentrations, to obtain a zinc-conjugated protein, and to obtain a zinc-conjugated polysaccharide protein. SOLUTION: This food material for zinc 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 zinc ingredients in 100 g of the basidiomycete. The second objective zinc-conjugated protein and the third objective zinc-conjugated polysaccharide protein are such ones as to each contain >=5 g of zinc ingredients in 100 g of the zinc-conjugated protein and zinc-conjugated polysaccharide protein respectively. A method for producing this food material for zinc supplement comprises cultivating at least one kind of basidiomycete selected from the genuses Lentinus, Glifora and Agaricus in a culture medium containing water-soluble zinc ingredients to let the basidiomycete assimilate zinc ingredients to include zinc ingredients in high concentrations in the protein and polysaccharide protein in the basidiomycete cell component and/or extracellular component. |
