Abstract: Two powdered protein products are produced from animal raw material of varying composition, in particular offal from bacon factories and cattle slaughterhouses.The offal is heat treated and separated mechanically into a fluid phase and a solid phase, which is powder-dried with subsequent removal of bone pieces to obtain the first protein powder. The fluid phase is separated into a sludge which is returned into the process, into a fat phase--which is processed into technical fat and into a size phase which is spray-dried separately in order to obtain the second protein powder. The powders produced are free flowing without any lumping tendency. The first powder has a protein content which corresponds to the content of conventionally produced meat-bone meal, whereas the second powder has a high protein content and has gluing properties and may therefore be used as a gluing agent or as a protein supplement for fodder.
