To provide an iron adsorption and/or absorption agent applicable to removal of iron in production of a beverage such as fruit juice, and of an alcoholic beverage or the like; and also to provide a method for removing iron effectively from water containing the iron, or a manufacturing solution for a material solution, in a manufacturing step or the like of producing the beverage, such as fruit juice and the alcoholic beverage, by use of the iron adsorption and/or absorption agent.
The iron adsorption and/or absorption agent is constituted of a residue of a yeast enzyme processing as its active ingredient. As the yeast residue of the active ingredient of the iron adsorption and/or absorption agent, a heavy liquid fraction is used which subsides by a low speed centrifugal separation out of the residues of the enzyme-processed yeast. The method uses the iron adsorption and/or absorption agent, and makes them come into contact with a solution containing iron, and adsorb and/or absorb the iron in the solution to remove the iron in the solution. The iron adsorption and/or absorption agent is applicable to the removal of the iron in the production of the beverage such as fruit juice, and of the alcoholic beverage or the like, and also is low-cost.
