<p>Non-woven substrate capable of releasing an aroma and/or flavor and of being produced by a process involving thermal fixation of cyclodextrin particles on the non-woven substrate, is new. An Independent claim is included for a process for producing a substrate that comprises either: (a) immersing a non-woven material in an aqueous bath or coating it with a paste or foam, where the bath paste or foam contains suspended cyclodextrin particles containing an aroma- and/or flavor-releasing substance, calendering the material and thermally fixing the cyclodextrin particles; or (b) coating a non-woven material with a powder comprising cyclodextrin particles containing an aroma- and/or flavor-releasing substance, spraying the coating with water and thermally fixing the cyclodextrin particles.</p> |
