PROCESS OF MAKING DRY, DISCRETE BEADS CONTAINING STABILIZED FAT-SOLUBLE VITAMIN IN A FATTY CORE WHICH IS ENCASED IN AN IRREVERSIBLY HEAT-DENATURED, WATER-RESISTANT PROTEINACEOUS DIGESTIBLE SHELL, SAID PROCESS COMPRISING MIXING A SOLUTION OF FAT-SOLUBLE VITAMIN IN A FAT HAVING A MELTING POINT OF ABOUT AT LEAST 35*C., AT A TEMPERATURE OF ABOUT 10*C. ABOVE THE MELTING POINT OF THE FAT WITH AN AQUEOUS SOLUTION OF A HEAT COAGULABLE, PROTEINACEOUS MATERIAL, HEATING THE MIXTURE TO EFFECT INCIPIENT DENATURATION OF THE PROTEIN, THE TIME-TEMPERATURE RELATIONSHIP FOR EFFECTING INCIPIENT DENATURATION BEING DETERMINED BY HEATING SPECIMENS OF SAID MIXTURE UNDER CORRELATED TEMPERATURES AND TIME INTERVALS WHICH SHOW THE CORRELATION OF TIME-TEMPERATURE AT WHICH THE MIXTURE CHANGES FROM A FLOWABLE MASS TO A NONFLOWABLE MASS, HOMOGENIZING SAID MIXTURE TO FORM AN EMULSION WITH THE OIL AS THE FINELY DISPERSED INTERNAL PHASE, AND SPRAY DRYING SAID HEATED EMULSION TO IRREVERSIBLY DENATURE THE PROTEIN.
