Abstract

A pancreatin preparation having reduced viral infectivity includes one or more pancreatin enzymes and peracetic acid (PAA). At least one pancreatin enzyme may be derived from an animal source such as a porcine pancreas gland. In a particular embodiment, the one or more pancreatin enzymes are selected from the group consisting of lipases, proteases, and amylases.

Claims (10)

1. A pancreatin preparation having reduced viral infectivity comprising one or more pancreatin enzymes and peracetic acid (PAA), wherein an enzymatic profile of the one or more pancreatin enzymes in the pancreatin preparation is the same as it would be if the pancreatin preparation had not been treated with PAA.

2. A pancreatin preparation having reduced viral infectivity comprising one or more pancreatin enzymes and peracetic acid (PAA), further comprising one or more porcine pancreas glands.

3. The pancreatin preparation of claim 1 , wherein the pancreatin preparation has a viral infectivity of Encephalomyocarditis virus (EMC) of at least 1 log 10 below that of a pancreatin control sample not treated with PAA.

4. The pancreatin preparation of claim 1 , wherein the pancreatin preparation has a viral infectivity of Murine Minute Virus (MMV) of at least 1 log 10 below that of a pancreatin control sample not treated with PAA.

5. The pancreatin preparation of claim 1 , wherein the pancreatin preparation has a viral infectivity of Porcine parvovirus (PPV) of at least 1 log 10 below that of a pancreatin control sample not treated with PAA.

6. The pancreatin preparation of claim 1 , wherein the pancreatin preparation has a viral infectivity of non-enveloped viruses of at least 1 log 10 below that of a pancreatin control sample not treated with PAA.

7. The pancreatin preparation of claim 1 , wherein at least one pancreatin enzyme is derived from an animal source.

8. The pancreatin preparation of claim 1 , wherein the one or more pancreatin enzymes are selected from a group consisting of lipases, proteases, and amylases.

9. The pancreatin preparation of claim 1 , wherein the preparation comprises a pancreatin active pharmaceutical ingredient (API).

10. The pancreatin preparation of claim 7 , wherein the one or more pancreatin enzymes are treated with PAA prior to extraction from the animal source.
