Abstract: Producing an aroma concentrate, comprises: (a) providing flavors and/or scents (I) having a positive sensory effect e.g. ethyl butyrate, and flavors and/or scents (II) having a negative sensory effect e.g. 1-5C-alcohol; (b) providing edible solvents; (c) adding the solvent to the solution of step (a); (d) providing an adsorption material in a device; (e) conducting the solution of step (c) through a device to absorb (I) on the absorption material; (f) providing edible solvents; and (g) desorbing the flavors and/or scents from the adsorption material. Producing an aroma concentrate, in which one or more flavors and/or scents (I) having a positive sensory effect are highly enriched around the factor of >= 1.5 compared to one or more flavors and/or scents (II) having a negative sensory effect, relative to an aqueous aroma, comprises: (a) providing an aqueous aroma comprising flavors and/or scents (I), which are ethyl butyrate, ethyl methyl butyrate-2, methyl capronate, linalool, alpha -lonone, beta -lonone, delta -decalactone, 2E-hexenol, 2E-hexenal, hexanal, beta -damascenone, octanal, nootkatone, p-menthenethiol-1,8, benzaldehyde, gamma -decalactone, linalool oxide, furfurylthiol-2, 4-vinylguaiacol, isomer of isopropyl methoxypyrazine, isomer of ethyldimethylpyrazine, indole, methyl jasmonate, jasmine lactone, dipropyl disulfide, dipropyl trisulfide, methyl propyl disulfide, L-menthol, menthone, L-carvone, isoamyl acetate, 2-acetyl-1-pyrroline, 2E,4Z-decadienal, 3,5-dimethyl trithiolane, citral, caryophyllene, 1-octen-3-ol, 1-octen-3-one, hydroxybenzyl acetone, cis-3-hexenol, 3Z-hexenol, methylbutyrate, geraniol, ethyl-2E,4Z-decadienoate, 8-mercapto-p-menth-1-en-3-one, 2E,4Z,7Z-tridecatrienal, 2E,5Z-undecadienal, nonanal, 4-octanolide, 5-octanolide, phenyl ethanol, wine lactone or menthofurolactone; and flavors and/or scents (II), which are 1-5C-alcohol, preferably methanol, ethanol, propanol, isopropanol, butanol, 2-methylbutanol, 3-methylbutanol, diacetyl, acetaldehyde, furfural, furfuryl alcohol, phenol, acetoin, dimethyl sulfide or methyl mercaptan; (b) providing one or more edible solvents; (c) adding the solvent to the solution of step (a), where the obtained solvent portion is adjusted so that (I) exhibits a log Pow*-value of >= 1.20 and the log Pow*-value which is calculated by the formula (log Pow* = log Pow-X*P'(X)/log Pow) (where log Pow is decade logarithm of the distribution coefficient of the flavors and/or scents between octanol to water, x is obtained solvent portion relative to the total volume portion, standardizes as 1 and P'(X) is polarity parameter for the corresponding solvent in the obtained solvent portion x); (d) providing an adsorption material in a suitable device; (e) passing the solution of step (c) through a device having adsorption material, so that (I) is adsorbed on the absorption material; (f) providing one or more edible solvents; and (g) desorbing the flavor and/or scents from the adsorption material with the solvent. Independent claims are included for: (1) the aroma concentrate producible by the above method; and (2) food-, luxury foodstuff-, beverage-, convenience food-, oral hygiene-, cosmetic- or pharmaceutical products, comprising the aroma concentrate and one or more basic materials, auxiliary material and/or additive.
