  • Food product and process for retaining moisture in cooked food
    Publication number: 20040058035
    Abstract: A meat or fish composition which retains moisture during cooking is provided. A dry protein mixture or an aqueous acidic protein solution derived from animal muscle tissue is added to the meat or fish prior to cooking. The dry protein mixture and aqueous acidic protein solution comprise myofibrillar proteins and sarcoplasmic proteins substantially free of myofibrils and sarcomeres.

    Publication date: March 25, 2004
    Inventors: Stephen D. Kelleher, Peter G. Williamson
  • Water soluble animal muscle protein product
    Publication number: 20030124239
    Abstract: A water soluble peptide composition derived from animal muscle tissue proteins is provided. The peptide composition contains less than about 1 weight percent fats and oils based upon the weight of the peptide composition and less than about 2 weight percent ash based on the weight of the peptide composition.

    Inventor: Stephen D. Kelleher
  • Protein composition and process for isolating a protein composition from a muscle source
    Publication number: 20020183488
    Abstract: A process is provided for isolating a protein component of animal muscle tissue by mixing a particulate form of the tissue with an acidic aqueous liquid having a pH below about 3.5 to produce a protein rich solution substantially free of myofibrils and sarcomere tissue structure. The protein rich aqueous solution can be treated to effect protein precipitation, followed by protein recovery.

  • Process for isolating a protein composition from a muscle source and protein composition
    Patent number: 6288216
    Abstract: A process is provided for isolating a protein component of animal muscle tissue by mixing a particulate form of the tissue with an acidic aqueous liquid having a pH below about 3.5 to produce a protein rich solution. A protein rich aqueous solution is separated from solids and lipids, including membrane lipids. The protein rich aqueous solution can be treated to effect protein precipitation, followed by protein recovery.

    Date of Patent: September 11, 2001
    Assignee: Advanced Protein Technology, Inc.
    Inventors: Herbert O. Hultin, Stephen D. Kelleher
  • High efficiency alkaline protein extraction
    Patent number: 6136959
    Abstract: A process for isolating edible protein from animal muscle by solubilizing the protein in an alkaline aqueous solution is disclosed.
