Process for stabilizing sterile evaporated milk

Claim 1

THE PROCESS OF PRODUCING STERILE EVAPORATED MILK WHICH CONSISTS IN STERILIZING BY HEAT EVAPORATED MILK MADE UP TO A MIXTURE OF TWO QUANTITIES OF MILK OF APPROXIMATELY THE SAME COMPOSITION, ONE OF SAID QUANTITIES BEING OF MILK HAVING INSUFFICIENT HEAT STABILITY TO WITHSTAND STERILIZATION BY HEAT WITHOUT COAGULATION, SAID PROCESS INCLUDING THE STEPS PRIOR TO STERILIZATION TO SUBJECTING THE OTHER QUANTITY OF MILK TO A HEAT TREATMENT AT A TEMPERATURE BETWEEN 250* F. AND 300* F. FOR ABOUT TWO SECONDS AT THE HIGHER TEMPERATURE TO A MAXIMUM OF ABOUT FOUR MINUTES AT THE LOWER TEMPERATURE TO GIVE THE MILK EXCESSIVE HEAT STABILITY AND LACK OF BODY AFTER STERILIZATION BY HEAT, AND MIXING SAID QUANTITIES IN PROPORTIONS WHICH AS DETERMINED BY EMPIRICAL TESTS WILL PRODUCE MILK OF PROPER HEAT STABILITY, SAID PROCESS INCLUDING THE STEP OF EVAPORATING ALL OF SAID MILK PRIOR TO SAID STERILIZATION.
