Abstract
Abstract Grain residues from mashed barley malt are separated from wort thereby produced and heated in an alkaline solution to solubilize protein. The alkaline solution is separated from the unsolubilized grain residues and acidified to precipitate water soluble protein. Beer is brewed from the wort and the unsolubilized grain residue can be used as animal feed.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
128 words
IN A PROCESS FOR RECOVERING PROTEIN SOLIDS FROM BREWER''S GRAINS IN WHICH SAID GRAINS ARE TREATED WITH AN ALKALINE SOLUTION AND IN WHICH SAID ALKALINE SOLUTION IS THEREAFTER TREATED TO RECOVER SOLIDS, THE IMPROVEMENT WHICH COMPRISES: SAID TREATMENT WITH AN ALKALINE SOLUTION BEING CARRIED OUT IN AN ALKALINE SOLUTION HAVING A PH OF ABOUT 9 AT A TEMPERATURE WITHIN THE RANGE OF FROM 180* TO 212*F. SO AS TO PLACE PROTEIN MATERIAL IN SAID BREWER''S GRAINS IN SOLUTION IN ORDER TO PRODUCE A MIXTURE OF AN INSOLUBLE RESIDUE AND A PROTEIN SOLUTION, SEPARATING SAID RESIDUE FROM SAID SOLUTION, ACIDIFYING SAID SOLUTION TO A PH OF ABOUT 6 SO AS TO PRECIPITATE PROTEIN SOLIDS FROM SAID SOLUTION, AND SEPARATING SAID PERICIPITATE PROTEIN SOLIDS FROM THE LIQUID IN SAID SOLUTION.
Claim 2
Dependent Claim
