Abstract
A low salt protein solution not capable of forming a gel is obtained from animal muscle tissue by forming an aqueous acidic protein solution which is filtered to remove salt and acid. The low salt protein solution can be formed into a gel by adding a physiologically acceptable salt to the low salt protein solution and heating the resultant protein solution with added salt.

The process for recovering a low salt protein solution derived from animal muscle tissue and containing between about 1.9 and 25 weight % protein based on the weight of the solution and protein to salt weight ratio greater than about 35, said solution not capable of being formed into a gel by when heated to a temperature of 55° C. or lower which comprises:
- forming an aqueous acidic protein solution including said protein and having a pH less than about 3.5 from a particulate form of said 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, 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,
- filtering said protein rich aqueous phase to form a retentate containing myosin protein and actin protein and comprising a low salt protein solution and
- recovering said retentate.
