Aroma particles

Abstract

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, characterised in that the matrix of the particles contains from 20 to 80 wt. % carbohydrate polymers having an average molecular weight greater than 1000.  
     
     
         2 . Aroma particles according to  claim 1 , characterised in that the matrix of the particles contains from 30 to 70 wt. % carbohydrate polymers having an average molecular weight greater than 1000.  
     
     
         3 . Aroma particles according to  claim 1 , characterised in that the matrix of the particles contains from 40 to 60 wt. % carbohydrate polymers having an average molecular weight greater than 1000.  
     
     
         4 . Aroma particles according to  claim 1 , characterised in that the matrix of the particles contains an emulsifier.  
     
     
         5 . Aroma particles according to  claim 4 , characterised in that the matrix contains monoglycerides in a quantity of from 0.5 to 3 wt. %.  
     
     
         6 . Aroma particles according to  claim 1 , characterised in that the matrix of the particles contains glucose.  
     
     
         7 . Aroma particles according to  claim 6 , characterised in that the matrix contains glucose in a quantity of from 0.5 to 5 wt. %.  
     
     
         8 . Aroma particles according to  claim 1 , characterised in that said particles have a glass transition temperature within the range 30 to 100° C.  
     
     
         9 . Process for the preparation of the aroma particles according to  claim 1 , comprising the steps: 
 extrusion of an aromatised melt followed by die-face pelletisation,    discharge of the melt from the extruder by way of an opening, and    comminution of the melt while still in an unsolidified state.    
     
     
         10 . Use of the aroma particles according to  claim 1  in foods, pharmaceuticals and consumer articles such as cosmetics, washing agents or household products.
