    Patent number: 6150547
    Abstract: This invention provides carbonic acid- and/or hydrogencarbonic acid-iron-hydrolyzates of casein complexes containing a large amount of iron, without causing precipitation after heating their aqueous solution or astringent taste and the processes for production thereof. The complexes of the present invention are prepared by (1) partial hydrolysis of carbonic acid- and/or hydrogencarbonic acid-iron-casein complexes with a protease or (2) mixing carbonic acid and/or hydrogencarbonic acid, iron and partial hydrolyzates of casein with a protease.
