Abstract

1422436 Protein fibres RALSTON PURINA CO 30 Oct 1973 [30 Oct 1972] 50419/73 Heading A2B [Also in Divisions B4 and B5] An improvement on the process of 1269769, wherein a confined flowing stream of a fluid slurry of a proteinaceous material is heated under a pressure and temperature sufficient to coagulate the protein in said material and is then forced through a plurality of orifices and thereafter contacted with a cooling medium. The slurry on leaving the orifices is preferably at a temperature of 240-315‹F and a pressure of 50-5000 psig and the cooling medium preferably refrigerated water either as a spray or a cooling bath. Examples show the use of soy bean isolate as a 21% slurry coagulated at 290‹F and 1000 psig and at 280‹F and 5000 psig followed by extrusion. The product may be used as a non-meat protein source of food. [GB1422436A]

Claims (8)

Claims 1. A method of continuously and simultaneously forming multiple discrete fibers from a bulbous substance in which a protein substance is suspended in water with a protein solids content of between 5% and 35% by weight, and then discrete elongated protein fibers are formed by continuously passing the suspension through pressurized by a heat exchange zone in which the slurry is heated to a temperature above 116 ° C but below a temperature that would damage the protein, and the protein is then subjected to temperature for a sufficient period of time so that the long, soft fibers are separated from the rest of the constituents the slurry and the heated slurry is continuously removed from said zone by the flange, and the elongated fibers and the remaining components of the slurry are discharged into the collection zone, where separate soft elongated protein fibers are separated from the remaining components of the slurry, characterized in that to prevent and the fibers coming out of said flange come into contact with each other, before the fibers are sufficiently cooled to prevent them from sticking together as they are transferred from said flange to the accumulation zone, the slurry is passed through a series of holes in said flange, each having a diameter. in the range of approximately 0.15 to 0.76 mm and distant from others, and after discharging from the holes, the fibers are immediately cooled to a temperature between about 5 and 15 ° C, by means of a coolant containing cooled air and / or cooled water, which is then removed from the fibers, 2. The method according to claim The process of claim 1, wherein chilled water is sprayed onto the fibers. 3. The method according to p. The method of claim 1, wherein the temperature of the suspension is maintained at 115-157 ° C when it leaves the orifice, and the pressure is between 3.5 and 350 kg / cm1. 4. The method according to p. The process of claim 1, wherein the water is cooled to a temperature ranging from 0 ° to 10 ° C. • ¦ 5. The method according to p. 1; characterized in that a continuously exchanged mass of chilled water is used as the cooling medium. ¦ 6. The method according to p. The process of claim 1, characterized in that 9-25 separate fibers shape simultaneously and discharge them into the collection zone. ¦. 7. The method according to p. The process of claim 1, wherein the fibers are washed and odors are removed by cooling the fibers with a cooling agent containing at least chilled water, and by removing water from the fibers. * Sklad-Prac.
