Abstract: Lumpy product or chunk, which is suitable for admixing to or as the sole constituent of animal food compositions and which contains proteins, one or more water-binding components, water and salt, in which it co mprises at least one phase, where the proteins as a result of a suitable denaturing stage form a high strength able to withstand processes such as sterilization and storage for several years without significant strength losses.

Abstract: A method for producing an animal feed or food item wherein at least one first flow of a viscous mass solidifies under corresponding first process conditions and at least one second flow of a mass of similar viscosity as the first flow, which second flow liquefies under corresponding second process conditions, are mixed in such a way that the individual flows are superimposed in layers. In a next step the flows are subjected, either sequentially or simultaneously, to the process conditions required for the solidification of the first flow and liquefaction of the second flow. A product produced in accordance with the method is described.
