Method and apparatus for the production of a watersoluble, low-iron protein product from blood cell raw material, and a low-iron, watersoluble protein product produced by hydrolysis of blood cell raw material

摘要

The present invention relates to a method for the production of a protein product from whole blood or a blood cell fraction separated from whole blood, said protein product being highly digestible, having a low content of iron and salts, being light brown, watersoluble and having good adhesive properties.;The method for the production of the protein product is characterised in that an aqueous blood cell material is subjected to hydrolysis at a temperature of between 140 and 190 °C and that the treated material is separated into a low-iron, liquid phase containing soluble proteins and an iron-rich, solid phase containing insoluble proteins, the liquid phase subsequently being concentrated or dried to a low-iron protein product, if desired.
