Abstract

Crystalline sucralose having a mean particle size of at most 10 microns, the maximum particle size being no more than twice the mean, exhibits enhanced stability to heat. Preferably the sucralose has a mean particle size of at most 5 microns and a maximum particle size of at most 10 microns. A method of enhancing the thermal stability of crystalline sucralose comprises jet milling the sucralose to reduce the particle size, and render the size distribution such that the maximum size is no more than twice the mean.

Claims

1. Crystalline sucralose having enhanced thermal stability and a mean particle size of at most 10 microns, the maximum particle size being no more than twice the mean.

2. The crystalline sucralose of claim 1 having a mean particle size of at most 5 microns and a maximum particle size of at most 10 microns.

3. The crystalline sucralose of claim 1 having a maximum particle size of at most 6 microns.

4. The crystalline sucralose of claim 1 having a mean particle size of from 2 to 3 microns and a maximum particle size of at most 6 microns.

5. The crystalline sucralose of claim 4 having a maximum particle size of at most 4 microns.

6. A process of enhancing the thermal stability of crystalline sucralose which comprises jet milling the sucralose to reduce the particle size, and render the size distribution such that the maximum size is no more than twice the mean.

7. The process of claim 6, wherein the particle size is reduced to a mean of no more than 10 microns.

8. The process of claim 7, in which the particle size is reduced to a mean dimension of at most 5 microns at a maximum particle size of at most 10 microns.

9. The process of claim 7, in which the particle size is reduced to a mean dimension of 2 microns at a maximum particle size of at most 6 microns.

10. The process of claim 6, in which the milling is effected at a fluid pressure of 207,000 Pa to 690,000 Pa.
