procedure and installation for the manufacture of a vandoploeseligt, jernfattigt protein product from a blodcelleholdigt raw material and a vandoploeseligt proteinmateriale

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 DEG 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.
