Abstract
Heat resistant carbonate- and/or hydrogencarbonate-iron-Lf complexes in which one molecule of lactoferrin is bound with 15 molecules or over of iron via carbonic acid and/or hydrogencarbonic acid. Process for the production of above mentioned complexes prepared by adjusting pH.ltoreq.7 by adding alkali salts of carbonic acid and/or hydrogencarbonic acid to an aqueous solution containing an iron salt exhibiting pH.ltoreq.4 when dissolved in water and lactoferrins, or adding an iron salt and lactoferrin solution to carbonic acid and/or hydrogencarbonic acid solution, or adding the iron salt or its solution to a solution containing carbonic acid and/or hydrogencarbonic acid and lactoferrins. The resultant lactoferrin complexes are highly heat resistant and useful as raw materials of foods, medicines, feeds, cosmetics and so forth.
