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
The process for recovering a protein composition substantially free of membrane lipids from animal muscle tissue, said protein composition capable of being formed into a gel, when heated, which comprises:
- providing particulate animal muscle tissue free of internal organs, intestines and head of an animal,
- forming a protein rich aqueous liquid solution including said protein composition from said particulate animal muscle tissue and an aqueous liquid composition having a pH less than about 3.5 which does not substantially degrade protein of said protein rich composition,
- treating said protein rich aqueous liquid solution by centrifugation to form a plurality of phases including an aqueous liquid phase containing a substantial majority of said protein composition from said animal muscle tissue and a second phase containing said membrane lipids,
- separating said aqueous liquid phase from said second phase and recovering said protein composition from said aqueous liquid phase.
