Abstract:
1. A process for recovering a low salt protein solution derived from animal muscle tissue, said solution being characterized as containing between about 1.9 and 25 weight % protein based on the weight of the solution, having a protein to salt weight ratio greater than about 35, and wherein said solution does not form a gel when heated to a temperature of 55° C. or lower, said process comprising: forming an aqueous acidic protein solution including a particulate form of said animal muscle tissue and an aqueous liquid, wherein the solution has a pH less than about 3.5 and does not substantially degrade protein of said animal muscle tissue, centrifuging said aqueous acidic protein solution to form a protein rich aqueous phase and a nonaqueous phase containing membrane lipids, recovering said protein rich aqueous phase, ultrafiltering said protein rich aqueous phase to form a retentate containing myosin protein and actin protein, and recovering said retentate, wherein said retentate comprises the low salt protein solution.
