Aroma particles
The invention relates to vitreous aroma particles and the preparation thereof, as well as to the use thereof in foods, consumer articles and pharmaceuticals.
1. Aroma particles comprising a matrix and an aroma that have been prepared by extrusion of an aromatised melt followed by die-face pelletisation while the aromatised melt is still in an unsolidified state, wherein the matrix of the aroma particles contains from 20 to 80 wt. % carbohydrate polymers having an average molecular weight greater than 1000, and glucose in a quantity of from 0.5 to 5 wt. %, based on the total weight of the melt.
2. Aroma particles according to claim 1 , wherein the matrix of the aroma particles contains from 30 to 70 wt. % carbohydrate polymers having an average molecular weight greater than 1000.
3. Aroma particles according to claim 1 , wherein the matrix of the aroma particles contains from 40 to 60 wt. % carbohydrate polymers having an average molecular weight greater than 1000.
4. Aroma particles according to claim 1 , wherein the matrix of the aroma particles contains an emulsifier.
5. Aroma particles according to claim 4 , wherein the matrix contains monoglycerides in a quantity of from 0.5 to 3 wt. %.
6. Aroma particles according to claim 1 , wherein aroma particles have a glass transition temperature within the range 30 to 100° C.
7. Aroma particles according to claim 1 , wherein the matrix of the aroma particles contains 30 to 70 wt-% water-soluble compounds having molecular weights within the range of 90 to 950.
8. Aroma particles comprising a matrix and an aroma that have been prepared by extrusion of an aromatised melt followed by die-face pelletisation at the die-face while the aromatised melt is still in an unsolidified state, wherein the matrix of the aroma particles contains:
30 to 70 wt. % carbohydrate polymers having an average molecular weight greater than 1000, and
30 to 70 wt-% water-soluble compounds having molecular weights within the range of 90 to 950, and glucose in a quantity of from 0.5 to 5 wt. %, based on the total weight of the aromatised melt.
9. Aroma particles according to claim 8 , wherein the matrix of the aroma particles contains from 40 to 60 wt. % carbohydrate polymers having an average molecular weight greater than 1000, and
40 to 60 wt-% water-soluble compounds having molecular weights within the range of 90 to 950, based on the total weight of the aromatised melt.
10. Aroma particles according to claim 8 , wherein the matrix of the aroma particles contains an emulsifier.
11. Aroma particles according to claim 10 , wherein the matrix contains monoglycerides in a quantity of from 0.5 to 3 wt. %.
12. Aroma particles according to claim 8 , wherein said particles have a glass transition temperature within the range 30 to 100° C.
