<p>An edible textured protein product is prepared by the unidirectional freezing of an aqueous mixture of protein and alginate to form vertically aligned protein fibers, slicing the frozen mass to form fiber bundles, gelling the alginate in each bundle to reinforce the well-defined fiber structure, permanently setting the protein fiber structure by heat and then adjusting the texture with a sequestering agent. The resulting product has certain textural and nutritional properties of natural meat and can be flavored, colored, texturized, shaped, molded, cooked and substituted for meat. By controlling the protein source, alginate type and concentration, slice thickness, type and amount of sequestering agent and length of time exposed to the sequestering bath the textural properties of the material can be varied to simulate a variety of meat products.</p> |
