Abstract:
1. A method for reducing the viral content of biological extracts which contain solids without reducing the activity of the enzymes contained in the biological extract, comprising the steps (a) providing a biological extract from an animal pancreas, which biological extract contains solids, comprising at least one biologically active substance, selected from the group consisting of enzymes, proteins and peptides, and a mixture of such substances; and (b) subjecting the extract provided in step (a) to a high-pressure treatment, for a duration of 1 to 60 minutes at a pressure of between 3000 to 6000 bar, wherein the biological activity of the biological extract which contains solids after the high-pressure treatment is at least 50% of the biological activity of the biological extract which contains solids before the high-pressure treatment, and
