Abstract:
1. A process for preparing a flavoring concentrate comprising one or more flavoring and/or aromatic substances which convey a positive sensory impression and one or more flavoring and/or aromatic substances which convey a negative sensory impression, wherein each of the one or more flavoring and/or aromatic substances which convey a positive sensory impression are more concentrated by a factor of 1.5 or more, as compared to the one or more flavoring and/or aromatic substances which convey a negative sensory impression, based on an aqueous flavoring, comprising: a) preparing an aqueous flavoring comprising: b) preparing at least one solvent, wherein the solvent is suitable for foodstuffs, c) adding the solvent of step b) to the solution of step a), and adjusting the resulting solvent proportion so that each of the one or more flavoring and/or aromatic substances from group i) have in each case a log Pow* value of greater than or equal to 1.20, wherein the log Pow* value is calculated as follows: d) preparing an adsorption material in a suitable apparatus, e) passing the solution of step c) through an apparatus with adsorption material of step d) so that the one or more flavorings and/or aromatic substances which convey a positive sensory impression are adsorbed on the absorption material, f) preparing at least one solvent suitable for foodstuffs, g) desorbing the flavoring and/or aromatic substances from the adsorption material of step e) with the solvent of step f), such that each of the one or more flavoring and/or aromatic substances from group i) are present in a higher concentration as compared to the one or more flavoring and/or aromatic substances from group ii), in each case by a factor of 1.5 or more than in the aqueous flavoring of step a).
