Abstract
The present invention relates to a method for the production of a powdered protein product from whole blood or a blood cell fraction separated from whole blood, the 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 powdered protein product is characterized in that an aqueous blood cell material is subjected to hydrolysis at a temperature of between 140.degree. and 190.degree. 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.
