Claim 1
Independent Claim
161 words
A METHOD FOR PREPARING A PRODUCT OF HIGH NUTRIENT VALUE, CHARACTERIZED BY SUBSTANTIAL FREEDOM FROM OBJECTIONABLE ODOR AND TASTE, WHICH COMPRISES ADMIXING AN AQUEOUS SLURRY OF LACTALBUMIN WITH A NON-TOXIC ALKALINE MATERIAL AND MAINTAINING THE MIXTURE AT A TEMPERATURE IN THE RANGE OF 35 DEGREES C. TO 50 DEGREES C., THE PH OF SAID MIXTURE BEING CONTROLLED SO THAT IT FALLS WITHIN THE RANGE OF 7.5 TO 11.0, WHEREBY SAID SOLUTION UNDERGOES GELATINIZATION, ADDING A PROTEOLYTIC PANCREATIC ENZYME FREE FROM LIPOLYTIC ACTIVITY TO SAID GELATINIZED MASS AND HOLDING THE RESULTING MIXTURE AT A TEMPERATURE FALLING WITHIN THE RANGE OF 38 DEGREES C. TO 44 DEGREES C. FOR A PERIOD NOT EXCEEDING ABOUT TWO HOURS, WHILE MAINTAINING THE PH OF SAID MIXTURE AT LEAST 7.0 TO FORM A HYDROLYZED LACTALBUMIN HAVING NOT MORE THAN ABOUT 19% OF ITS TOTAL NITROGEN CONTENT IN THE FORM OF ALPHA AMINO NITROGEN CLARIFYING SAID REACTION MIXTURE TO RECOVER THE LIQUID EFFLUENT, AND THEN DRYING THE SAME.
