Abstract: A matrix for incorporating titanium dioxide into extruded plant protein extenders for natural meat products is disclosed. In particular, this matrix made from vegetable protein is useful for incorporating TiO.sub.2 tracer in extruded plant protein extenders in such a way that there will be reduced optical contrast with natural ground meat fibers.

Abstract: The present invention provides a process for the production of a protein isolate having low solubility with excellent functional properties as a complete or partial replacement for milk co-precipitate in a non-aqueous, "creme" filling used in cookies, snacks and the like. The process comprises; forming an aqueous slurry of an isolated soy protein; controlling the pH of the slurry to between about 4.5 to 5.8 by the addition of a monovalent alkali reagent; heating said slurry to a temperature of between about 170.degree.-240.degree. F.; and neutralizing said slurry to a pH of 6.8 to 7.2 in the presence of an alkaline earth cation to provide a low solubility protein isolate.

Abstract: An improved method for continuously and automatically manufacturing water soluble adhesives for use in coatings is disclosed. A continuous flow of water is heated, an antifoam agent is injected into the flow of water, the solids base for the adhesive is admixed into the flow at a predetermined level and an alkali cutting agent is added directly into the flow.

Abstract: A process of continuously forming pH modified protein filaments from a proteinaceous material is disclosed wherein an aqueous slurry of the proteinaceous material is formed having a proteinaceous solids content of between about 0.5 and 35% by weight. Discrete filaments are formed by conducting the slurry under pressure through a heat exchange zone and heating the slurry to a temperature which is above 240.degree. F. whereby the protein is subjected to such temperature for a sufficient period of time so that elongated filaments are thereafter separated from the remaining constituents of the slurry. The heated slurry is then continuously removed from said heat exchange zone through a back pressure creating orifice whereby discharge of said filaments from the heat exchange zone to a collecting zone is controlled by confining the stream of said filaments to within a total angle of between about 4.degree. and 90.degree..
