  • Patent number: 9107966
    Abstract: The invention is a method for reducing the viral and microbial content of biological extracts which contain solids. The method comprises the steps of, (1), providing a biological extract which contains solids that comprise a biologically active substance, selected from enzymes, proteins and peptides, or a mixture of such substances; and (2) subjecting the biological extract to a high-pressure treatment; wherein the biological activity of the biological extract after the high-pressure treatment is at least 50% of the biological activity of the biological extract before the high-pressure treatment.

  • Patent number: 8765471
    Abstract: The use of a neutral protease (NP) together with a collagenase consists in that a neutral protease which is not contained in a collagenase enzyme preparation and which is not produced by a recombinant production is mixed before the beginning of a tissue dissociation with a collagenase or a collagenase enzyme preparation with an individual dosage of the quantitative proportions of neutral protease and collagenase for improving the isolation results with respect to yield, viability and integrity of the cells.

  • Patent number: 8283147
    Abstract: The invention relates to a method for producing pancreatin with reduced viral and microbial contamination, comprising the steps of (a) providing the pancreatin in solid form with a residual moisture of 0.5 weight % or less, down to almost zero, based on the pancreatin provided; (b) subjecting the pancreatin provided in step (a) to a heat treatment at a temperature of 84° C., preferably 80° C. and below; wherein, the biological activity of the pancreatin obtained in step (b) corresponds to at least 50% of the biological activity of the pancreatin provided in step (a); and the viral infectiousness of the pancreatin obtained in step (b) has been reduced by a factor of more than 1 log10 in comparison with the viral infectiousness of the pancreatin provided in step (a), as well as a pancreatin produced according to this method and its use for producing a medicine or a nutritional supplement.
