An electrolytically anodically produced finely porous metal oxide layer as support is brought into contact with the aroma substances and/or flavourings to be transferred or impregnated with these. For transfer or uniform delivery of the aroma substances and/or flavourings, the support is brought into contact with the receiving medium or stored together with this. In the metal oxide layer serving as support, the pore diameter is 0.05-0.5 mu m and the pore depth is 1-60 mu m. The process is used for transferring aroma substances and/or flavourings to foodstuffs and luxury foods. The process enables uniform release of the entire aroma composition and/or flavouring composition without separation of their components in a simple and easily usable manner. The carrier used is expediently and preferably an electrolytically anodically oxidised aluminium foil, preferably deep-etched before the anodic oxidation. |
