Abstract:
1. A process for recovering from meat trimmings containing fat and protein a protein composition having a color of 75 to 52 L*, 25 to 15 a*, and 23 to 16 b*, wherein the meat trimmings are obtained from beef and wherein the meat trimmings have an average fat content between about 50% and 80% by weight and a lean content between about 20% and 50% by weight, said process comprising the steps of: a) comminuting the meat trimmings in water, b) adding a food grade acid to the comminuted meat trimmings to effect a pH in the range of 3.6 to 4.4 thereby to solubilize the protein, c) after addition of the food grade acid in step b), separating solid fat from solubilized protein, and d) adding a food grade alkali to the solubilized protein to increase the pH in the solubilized protein and to precipitate the solubilized protein to produce a precipitated protein composition with a color of 75 to 52 L*, 25 to 15 a*, and 23 to 16 b*, wherein the precipitated protein composition has 14% or greater by weight protein and less than 10% by weight fat.
