Abstract
A process is provided for isolating a protein component of animal muscle tissue by mixing a particulate form of the tissue with an acidic aqueous liquid having a pH below about 3.5 to produce a protein rich solution. A protein rich aqueous solution is separated from solids and lipids, including membrane lipids. The protein rich aqueous solution can be treated to effect protein precipitation, followed by protein recovery.
Claims22
A protein rich solid composition isolated from an animal muscle tissue which comprises myofibrillar proteins substantially free of animal membrane lipids, said proteins capable of being formed into a gel.
A protein rich composition isolated from an animal muscle tissue which comprises myofibrillar proteins substantially free of animal membrane lipids in aqueous solution having a pH less than about 3.5 said proteins capable of being formed into a gel.
A protein rich gel composition isolated from an animal muscle tissue which comprises myofibrillar proteins substantially free of animal membrane lipids.
