Protein product and process for making protein product from uncooked meat purge
A precipitated purge protein is obtained from animal muscle tissue purge. Animal muscle tissue purge is mixed with a food grade acid to form an aqueous acidic solution of animal muscle tissue purge. The acidic solution is mixed with a food grade base to precipitate the protein in the solution. The precipitated protein then is recovered.
1 . An animal muscle purge protein composition comprising sarcoplasmic proteins and myofibrillar proteins derived from purge from uncooked meat obtained by the process comprising:
a. mixing said comminuted animal muscle purge with a food grade acid composition to form an aqueous acidic solution of animal muscle protein having a pH below about 3.5.
b. mixing said aqueous acidic solution of purge protein with a food grade alkaline composition to form an aqueous composition of purge protein having a pH between about 4.7 and about 11.0 to precipitate said protein and
c. recovering said precipitated protein.
2 . The composition of claim 1 wherein the purge is beef purge.
3 . The composition of claim 1 wherein the purge is pork purge.
4 . The composition of claim 1 wherein the purge is lamb purge.
5 . The composition of claim 1 wherein the purge is chicken purge.
6 . The composition of anyone of claim 1 , 2 , 3 , 4 or 5 wherein the pH of the aqueous acidic solution is between about 2.5 and about 3.5.
7 . The composition of anyone of claim 1 , 2 , 3 , 4 or 5 wherein the pH of the precipitated protein is between about 5.5 and about 9.5.
8 . The process for forming animal muscle purge precipitated protein comprising sarcoplasmic proteins and myofibrillar proteins which comprises:
a. mixing said animal muscle purge with a food grade acid composition to form an aqueous acidic solution of animal muscle protein having a pH between about 2.0 below about 3.5.
b. mixing said aqueous acidic solution of purge protein with a food grade alkaline composition to form an aqueous composition of purge protein having a pH between about 4.7 and about 11.0 to precipitate said protein and
c. recovering said precipitated animal muscle purge.
9 . The process of claim 8 wherein the purge is beef purge.
10 . The process of claim 8 wherein the purge is pork purge.
11 . The process of claim 8 wherein the purge is lamb purge.
12 . The process of claim 8 wherein the purge is chicken purge.
