Abstract:
1. A method of preparing a food or feed ingredient for incorporation into a human food or animal feed, said method comprising the steps of: extruding an extrudable mixture comprising dry fraction and a byproduct slurry fraction from a twin-screw extruder to create a wet extrudate having a moisture content of from about 38-50% by weight, based upon the total weight of the extrudate taken as 100% by weight, and thereafter drying the wet extrudate to give said food or feed ingredient, said extruding step comprising the steps of first directing at least a portion of said dry fraction and at least a portion of said byproduct slurry fraction together through a preconditioner, and then forming said extrudable mixture in said twin-screw extruder, said dry fraction portion including one or more ingredients selected from the group consisting of a source of plant-derived starch, a source of plant-derived protein, a source of animal-derived functional protein, and mixtures thereof, said byproduct slurry fraction portion selected from the group consisting of byproduct slurries from meat, poultry, dairy, vegetable, and fruit processing, and mixtures thereof, said byproduct slurry fraction being an aqueous blend comprising byproduct solids and from about 40-95% by weight water, the dry fraction and the slurry fraction comprising an extrudable mixture within said twin-screw extruder, said extrudable mixture containing from about 70-215% by weight of said slurry fraction, where the total weight of the dry fraction is taken as 100% by weight.
