US 6,150,547 A · Iron-casein complex hydrolyzate and process for the production thereof

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. These complexes are used favorably as food additives, raw materials of medicines or feed components due to their lack of precipitation by heating their aqueous solution, or astringent taste.

Dependent claims

A carbonic acid- and/or hydrogencarbonic acid-iron-partial hydrolyzate of a casein complexes having following properties of 1) to 4):

1) The complexes containing 1-1,000 atoms of iron and one molecule or more of carbonic acid and/or hydrogencarbonic acid per one molecule of casein prior to the hydrolysis,
2) the dried powder of the complex dissolves in water to give at least 15% solution,
3) the aqueous solution shows no precipitation by heating at 90.degree. C. for 10 minutes, and
4) the solution shows no iron characteristic astringent taste.
