1. Method of modifying the physical and biochemical characteristics of animal blood after slaughter or of the serum or plasma thereof after separation, characterized in that it consists of heating the blood in the liquid state before coagulation, or the serum or plasma thereof after separation, mass heating being performed, the said mass of blood or plasma or serum (hereinafter designated by the common name "blood") being stirred continuously and slowly in such a way that the fibrinogen of the blood is not transformed into fibrin, the heating operation thus defined being continued progressively to a temperature which substantially corresponds to the boiling temperature at which the blood is then in the form of a stable and slightly moist grumous phase, with the essentially total disappearance of any liquid phase, with the exception of a slight yield of liquid, the weight of which, added to the loss resulting from the evaporation, does not determine a total loss of more than 5%. |
