IN THE PROCESS OF PREPARING SIRUPS FROM ACID STARCH HYDROLYSATE LIQUORS HAVING A D. E. VALUE WITHIN THE RANGE OF ABOUT 10 TO ABOUT 32 BY HYDROLYZING STARCH WITH ACID TO A PREDETERMINED D. E. VALUE FOLLOWED BY NEUTRALIZATION OF THE ACID IN THE LIQUOR TO A PH OF ABOUT 5 AND REFINING AND EVAPORATING THE LIQUOR, THE IMPROVEMENT WHICH COMPRISES ADDING TO THE LIQUOR PRIOR TO NEUTRALIZATION A SUFFICIENT AMOUNT OF MATERIAL FROM THE GROUP CONSISTING OF FATTY ACIDS DERIVED FROM THE HYDROLYSIS OF CORN STARCH; FATTY ACIDS DERIVED FROM THE HYDROLYSIS OF SORGHUM GRAIN STARCH; HOUSEHOLD SOAPS; SODIUM STEARATE PALMITIC ACID, STEARIC ACID, OLEIC ACID, LINOLEIC ACID, LINOLENIC ACID, ARACHIDIC ACID, LIGNOCERIC ACID, MYRISTIC ACID, LAURIC ACID, CAPRIC ACID; SOLUBLE SOAPS DERIVED FROM SUCH ACIDS, AND MIXTURES OF ANY OF SUCH SOAPS AND ACIDS, TO REACT WITH THE STARCH AND/OR STARCH-LIKE BODIES PRESENT TO FORM A COMPLEX WITH THE STARCH, COOLING THE LIQUOR TO A TEMPERATURE WITHIN THE RANGE OF ABOUT 60* F.
