  • Method for reducing or inactivating viral and microbial content in the processes for the manufacture of pancreatin
    Patent number: 11952603
    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.
    Type: Grant
    Filed: August 22, 2018
    Date of Patent: April 9, 2024
    Assignee: SCIENTIFIC PROTEIN LABORATORIES, LLC
    Inventors: Kenneth S. Manning, Yan Wang, Dustin Nielsen, Ryan Ruf, Colin Crowley, Jon Restivo, Dana Spangenberg, Karla Anhalt, Mark Romich, Anisha Akula, Carmen Fritz

  • Method for reducing or inactivating viral and microbial content in the processes for the manufacture of pancreatin
    Patent number: 10093916
    Abstract: A method for the reduction or inactivation of viral and microbial content in the manufacturing of pancreatin API is disclosed. The method includes treating animal-derived tissue with peracetic acid to reduce viral activity and bacterial load prior to processing. In particular, the method includes treating porcine pancreas glands with peracteic acid prior to extracting a pancreatin API from the treated glandular tissue.
