<p>A heat-resistant carbonate and/or bicarbonate-iron-lactoferrin combination wherein at least 15 iron molecules are bonded to one lactoferrin molecule via carbonate and/or bicarbonate. The production process comprises adding an alkali carbonate and/or bicarbonate to a solution containing a lactoferrin and an iron salt having a pH value of 4 or less when dissolved in water to thereby adjust the pH value to 7 or less, or adding a solution containing an iron salt and a lactoferrin to a solution containing a carbonate and/or bicarbonate, or adding an iron salt or a solution thereof to a solution containing a carbonate and/or a bicarbonate and further a lactoferrin. The combination has a high heat resistance and is useful as the starting material of food, drug, feed, cosmetic, and so forth.</p> |
