Abstract:
A method for isolating edible protein from animal muscle, the method comprising:(a) obtaining a mixture comprising animal muscle and water, wherein the animal muscle comprises less than about 15% by weight of the mixture;(b) increasing the pH of the mixture to a level sufficient to solubilize at least 75% of the animal protein in the animal muscle mixture;(c) centrifuging the mixture, after at least 75% of the animal protein is solubilized, at about 5,000.times.g or higher so that membrane lipids are separated from an aqueous phase, and collecting the aqueous phase;(d) precipitating the protein from the aqueous phase; and(e) collecting the precipitated protein, thereby isolating the edible protein from the animal muscle, wherein the collected precipitated protein provides a yield of at least 70% of the total animal muscle protein.
