For the manufacture of bone gelatine a downscaled Pilot model has been developed and tested to reflect as close as possible the industrial processes and to represent the typical manufacturing conditions. Spiking crushed fresh bone with 30 I V infected mouse brain (BSE agent) and 263 K infected hamster brain (scrape agent) and processing these materials through the downscaled model to produce gelatin. Using the processed material from the whole process to determine the residual infectivity of gelatine and declaim-phosphate by bioassay. Evaluating separately the inactivation capacity on individual process steps of the finishing unit operations by spiking the industrial starting material and processing this material through these steps and measuring the remaining infectivity. In total 17 samples are prepared and submitted to bioassay. All samples are additionally tested by immunoblotting.
