Claim 1
Independent Claim
155 words
PROCESS FOR STABILIZING L-ASPARYL-L-PHENULALANINE METHYL ESTER CRYSTALS INTO A PARTICULATE FORM ADAPTED TO BE INTERMIXED WITH OTHER POWDEROUS MATERIALS AND BE FREE-FLOWING THEREWITH WHICH COMPRISES ADMIXING SAID ESTER CRYSTALS AND A FUSING AND MATRIX-FORMING MATERIAL HAVING A MOISTURE CONTENT LESS THAN 10%, SAID MATERIAL BEING MOLTEN AT A TEMPERATURE AT OR BELOW 370*F. SOLIDIFYING INTO A SOLID MASS WHEN COOLED TO BELOW ITS MELTING POINT AND RETAINING A THERMOSETTING SOLID CONDITION AT AMBIENT CONDITIONS, HEATING THE ADMIXTURE OF SAID ESTER CRYSTALS AND SAID FUSING AND MATRIX-FORMING MATERIAL TO A TEMPERATURE SUFFICIENT TO CONVERT SAID FUSING AND MATRIX-FORMING MATERIAL INTO A CONTINOUS MOLTEN CONDITION BUT BELOW THE MELTING POINT OF THE ESTER CRYSTALS, WHEREIN THE ESTER CRYSTALS ARE DISCRETELY DISTRIBUTED; COOLING THE MOLTEN MASS TO FUSE THE SAME AND PERMANENTLY FIX THE EXTER CRYSTALS IN A DISPERSED PHASE; AND SUB-DIVIDING THE COOLED MASS TO A PARTICULAR SIZE THEREBY PRODUCING PARTICLES WHICH ENCAPSULATE THE CRYSTALS DISTRIBUTED THEREIN.
