  • Blood pressure lowering peptides in a single enzymatic step
    Patent number: 7879804
    Abstract: A process to produce IPP and VPP from a protein source that comprises the -I-P-P- and -V-P-P- sequence in its protein sequence and whereby at least 40% of -I-P-P- sequence present in the protein source is converted into the peptide IPP and at least 40% of the -V-P-P- sequence present in the protein source is converted into the peptide VPP, which comprises the use of a proline specific endoprotease and an amino-peptidase preferably in a single enzymatic step.
    Type: Grant
    Filed: December 21, 2005
    Date of Patent: February 1, 2011
    Assignee: DSM IP Assets B.V.
