Carbonic Acid → Carbonic Acid

Mixing of solution containing a carbonic acid, a hydrogencarbonic acid, or a carbonic acid and a hydrogencarbonic acid (solution A) and a solution containing iron and a partial hydrolyzate of casein (solution B) using hydrolyzates of casein prepared by partial hydrolysis of casein with a protease in advance to give a carbonic acid- and/or hydrogencarbonic acid-iron-partial hydrolyzates of casein complex. However, the molar concentration of iron ion in solution B is made 1/3 or less of those of a carbonic acid and a hydrogencarbonic acid ions dissolved in a mixed solution of A and B. The molar number of partial hydrolyzates of casein in solution B is adjusted to 11/1,000 molar number of iron ion in solution B calculated as casein before hydrolysis.
