Claims
- 1. A process for fixation of sweet L-aspartic acid derivative dipeptide compounds which comprises forming a dispersion containing a slurry of undissolved particles of said sweetening compound in an aqueous solution of encapsulating agent, the level of said undissolved sweetening compound solids being in excess of the total sweetening solids of said compounds in solution in said dispersion and the dispersion being maintained at a temperature low enough to assure the existence of at least a part of the sweetening compound as discretely distributed undissolved particles, and drying said dispersion to a moisture content below 5% and a density greater than 0.2 grams per cc. to encapsulate the particles of said sweetening compound in said encapsulating agent.
- 2. The process of claim 1 wherein the dispersion is sprayed as droplets and then dried.
- 3. The process of claim 1 wherein the sweetening compound is milled while in an aqueous medium to effect said dispersion.
- 4. The process of claim 3 wherein the sweetening compound is admixed with the encapsulating solution and then milled.
- 5. The process of claim 1 wherein the encapsulating agent is a dextrin material having a D.E. less than 40.
- 6. The process of claim 5 wherein the dextrin has a dextrose equivalency of 5-15 and wherein the dextrin material contains a major amount of oligosaccharides.
- 7. The process of claim 1 wherein the sweetening compound is a lower alkyl ester of L-aspartyl-L-phenylalanine.
- 8. The process of claim 7 wherein the slurry is maintained below 160.degree. F.
- 9. The process of claim 1 wherein the dispersion is acidified.
- 10. The process of claim 9 wherein the acid content of the dispersion is a minor percent of the fixing solids.
- 11. The process of claim 10 wherein the acid is less than 10% of the composition.
- 12. The process of claim 1 wherein the dispersion is maintained below 100.degree. F throughout processing.
- 13. The process of claim 1 wherein the sweetening compound is present at a level of 30 - 90% of the total solids in the dispersion.
- 14. The process of claim 1 wherein the dispersion is milled at a temperature less than 160.degree. F and then spray dried at an inlet air temperature below 475.degree. F to produce discrete hollow spherical particles.
- 15. The process of claim 14 wherein the sweetening compound is at least 15% of the total solids in the dispersion and the ratio of said sweetening compound to said encapsulating agent is 1:4 to 4:1 and wherein compound particles are milled in said dispersion by passage through a narrow orifice having an opening no larger than 125 microns.
- 16. The process of claim 15 wherein said sweetening compound is 30 - 90 percent of the total solids in said dispersion.
- 17. The process of claim 16 wherein said sweetening compound is a lower alkyl ester of L-aspartyl-L-phenylalanine.
- 18. The process of claim 17 wherein said ester is the methyl ester.
