Date Oct. 1, 1998Iron-casein complexes and methods for preparation thereof without iron characteristic astringent taste even by heat sterilization and having high iron supplying effect. The iron-casein complexes can be obtained by mixing three components of solution A containing i) carbonic acid, ii) hydrogencarbonic acid or iii) their mixtures, solution B1 containing iron, and solution B2 containing caseins in a suitable order. The resultant iron-casein complexes contain 1-1,000 atoms of iron and one molecule or over of carbonic acid and/or hydrogencarbonic acid for one molecule of caseins without exhibiting astringent taste even by heat sterilization. The iron-casein complexes exhibit superior anemia preventive effect than those of inorganic iron salts.
