Claim 1

THE PROCESS OF PRODUCING DEXTROSE LIQUORS, SUITABLE FOR SIRUPS OR CRYSTALLINE DEXTROSE, FROM STARCH CONTAINING MORE THAN ABOUT 1.0 PERCENT, DRY BASIS, OF INSOLUBLE PROTEIN, WHICH COMPRISES HYDROLYZING SAID STARCH IN AQUEOUS SLURRY WITH ACID TO A D.E VALUE WITHIN ABOUT 18 TO ABOUT 55 PERCENT, ADJUSTING THE PH OF THE PARTIAL HYDROLYZATE TO A VALUE WITHIN THE RANGE OF THE PH EMPLOYED DURING HYDROLYSIS AND 5.5, SEPARATING INSOLUBLE IMPURITIES FROM SAID PARTIAL HYDROLZATE, AND FURTHER HYDROLYZING SAID PARTIAL-HYDROLYZATE WITH ACID UNTIL THE D.E VALUE IS ABOVE ABOUT 60 PERCENT, ADJUSTING THE PH OF THE FINAL HYDROLYZATE TO A VALUE WITHIN THE PH EMPLOYED DURING THE LAST MEMTIONED HYDROLYSIS AND 5.5, AND SEPARTING INSOLUBLE IMPURTIES FROM SAID FINAL HYFROLYZATE, THE HYDROLYZATE IN AT LEAST ONE STAGE BEING TREATED WITH BENTONITE.
