  • Non-bitter protein hydrolyzates
    Patent number: 5266685
    Abstract: New protein hydrolyzates are produced by treating an aqueous solution of a protein hydrolyzate with an adsorptive resin functional to remove from the protein hydrolyzate bitter taste components, color and odor components and aromatic amino acids. The treated protein hydrolyzate solutions can be concentrated and dried if desired to powder form.
