  • Protein composition obtained from a muscle source
    Patent number: 7473764
    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.
