1339199 Texturizing protein material GENERAL MILLS Inc 26 July 1971 [27 July 1970] 35023/71 Heading C3H [Also in Divisions A2 and B1] The texturizing of particulate protein material, in which the material is contacted in a texturizing zone with a heated gaseous fluid at a fluid pressure of at least 15 p.s.i.g. for a time sufficient to provide the desired texturizing effect, may be carried out by propelling the particles from a pocket 41, see Fig. 5, of a rotary valve 12, see Fig. 1, by means of superheated steam from a line 26 into tube 14 and out through nozzle 59 into the atmosphere against the back pressure in concentric surge tank 13. In an alternative embodiment (Fig. 7, not shown), the surge tank consists of a small compartment (66) surrounding the tube (14A) and at some distance a larger compartment (67) connected to it by piping. In yet a further embodiment (Fig. 8, not shown), back pressure is produced by injecting water under pressure into tube (14B) through a line (71). The rotational sequence (clockwise) of the rotary valve is depicted in Figs. 4 to 6. Line 27 serves to depressurize the pocket prior to refilling. There may be 4, 6 or 8 pockets in the valve member. Examples are directed to texturizing the following protein materials in particulate form; say protein isolate; blended soybean concentrate and soy protein isolate with, optionally, glycerol monostearate and caramel colour; blended soybean concentrate, soy protein isolate, sugar, onion powder, caramel, hydrolysed protein flavouring (beef flavour) and red colouring; soy bean flour, glycerol monostearate and caramel; soy bean flour and wheat flour; defatted cottonseed flour alone or mixed with soy protein isolate; gluten; yeast flour; and sodium caseinate. The texturized protein material may be impregnated with meat analog serum including binder, flavouring and water, to produce a simulated beef or chicken chunk. The protein material may be ground, hydrated and mixed with ground beef or pork sausage, thus acting as a meat extender. A simulated ground beef may be prepared by mixing the protein material with beef tallow, corn flour, egg albumin, brown sugar, onion powder, salt, beef flavouring and caramel colouring, and heating to set the egg albumin.
