A process for the production of a concentrated aroma solution from an aqueous solution containing water-soluble aroma components; for example coffee, tea or fruit aroma components. Soluble solids are added to the aqueous solution to provide a fortified solution. Then the fortified solution is chilled to provide ice and a concentrated aqueous liquid. The concentrated aqueous liquid has a concentration of soluble solids above about 9% by weight and contains water-soluble aroma components. At least a portion of the concentrated aqueous liquid is collected as the concentrated aroma solution. Little or no aroma components and soluble solids are lost in the ice and little or no deterioration of the aroma components occurs.

Procédé de production d'une solution concentrée d'arôme à partir d'une solution aqueuse contenant des composantes hydrosolubles de l'arôme, par exemple, de café, de thé ou de fruit. Des solides solubles sont ajoutés à la solution aqueuse pour l'enrichir. La solution enrichie est alors refroidie pour obtenir de la glace et une solution aqueuse concentrée. Cette solution présente une concentration en solides solubles supérieure à environ 9 % en poids et contient des composantes hydrosolubles de l'arôme. Au moins une partie du liquide aqueux concentré est recueillie sous forme de solution concentrée d'arôme. On observe peu ou pas de pertes de composantes d'arôme et de solides solubles dans la glace et peu ou pas de détérioration de ces composantes.
