Abstract

A chewing gum which consists of a chewing gum base, fats or waxes, fillers, additives and active substances, the chewing gum base being present in a particle size of 0.2 to 1 mm, together with the fillers, additives and active substances, in the matrix of fats and waxes. The tablet form is preferably coated with a tablet coating. Production is effected by separately comminuting the chewing gum base on the one hand and the matrix on the other hand at low temperatures, mixing the two types of granules and then pressing the mixture on a cooled tableting press. Finally, the tablets are coated with a covering layer and slowly heated to 40°-45° C.

Claims

1. A chewing gum comprising a chewing gum base in the form of particles embedded in a matrix;

said particles having a size in the range of 0.2 to 1 mm;

said matrix being selected from the group consisting of fats, waxes, and mixtures thereof and said matrix being 20 to 40 parts based on 100 parts of said chewing gum base.

2. The chewing gum as claimed in claim 1, further comprising at lease one filler.

3. The chewing gum as claimed in claim 1, further comprising at least one additive.

4. The chewing gum as claimed in claim 1, wherein said matrix has diffused at least partially into the surface of said particles.

5. The chewing gum as claimed in claim 1, wherein said chewing gum is physically shaped like a tablet and further comprising a tablet coating on said tablet.

6. A chewing gum as claimed in claim 1, further comprising at least one active substance.

7. A process for producing a chewing gum, comprising milling a substance at a temperature less than 0°

C. to produce particles having a size in the range from 0.2 to 0.5 mm;

said substance having a melting point in the range of from 35°

C. to 50°

C. and selected from the group consisting of fats, waxes, and mixtures thereof;

providing a chewing gum base in the form of particles having a size in the range of from 0.2 to 1 mm; and

combining the particles of said substance and the particles of said chewing gum base to produce at least one tablet in which the particles of said chewing gum base are embedded in said substance so that said substance is a matrix.

8. The process as claimed in claim 7, wherein the particles of said substance and the particles of said chewing gum base are combined so that said substance is in the range of from 20 to 40 parts based on a 100 parts of said chewing gum base.

9. The process as claimed in claim 7, wherein said combining step includes mixing the particles of said substance and the particles of said chewing gum base together in a vacuum, or at a temperature less than 5°

C., or in a vacuum and at a temperature less than 5°

C.

10. The process as claimed in claim 7, wherein said combining step includes combining the particles of said substance and the particles of said chewing gum base at a temperature of less than 5°

C., or in a cooled tableting press, or at a temperature less than 5°

C. and in a cooled tableting press.

11. The process as claimed in claim 7, further comprising coating said tablet.

12. The process as claimed in claim 11, wherein said coating step is carried out at a temperature from 35°

C. to 60°

C. over a period of time from about 10 to 20 minutes; and

thereafter cooling said coated tablet.

13. The process as claimed in claim 12, wherein said coating step is carried out at a temperature from 40°

C. to 45°

C.
