  • Method for preparing tryptophan rich peptides
    Patent number: 7977066
    Abstract: Described is a method for selectively isolating tryptophan containing peptides from an aqueous peptide mixture, including the steps of controlling the pH of the aqueous peptide mixture to 4.0-6.0, forming a precipitate of tryptophan containing peptides, and isolating the precipitated peptides. The aqueous peptide mixture is preferably obtained by enzymatic cleavage at acidic pH of a protein source. Further, peptides having a Trp content of 8-15 w/w % and the use thereof as a food additive and as an active ingredient in a medicament are described.
    Type: Grant
    Filed: October 23, 2008
    Date of Patent: July 12, 2011
    Assignee: Campina Melkunie B.V.
    Inventors: Leon Franciscus Mallee, Petronella Wilhelmina Josephina Rosa Caessens, Johannes Wilhelmus Leonardus Boumans
  • USE OF TRYPTOPHAN RICH PEPTIDES
    Publication number: 20100087359
    Abstract: The novel use of peptides derived from whey protein hydrolysate as active ingredient in a medicament or as food ingredient for elevating the cholescystokinin level in the blood, and for preventing or treatment of overweight and/or obesity, in an animal, including human, in need thereof.
    Type: Application
