Definitions

• the invention relates to a method for aromatizing tobacco smoke extracted from a cigarette, a cigarette end piece, in particular a cigarette filter for carrying out this method, and an application of this method.
• the object of the present invention is to provide a method which does not have the disadvantages mentioned above, that is to say which, for example, enables the production of flavored filter cigarettes without contamination of the production plant, requires relatively small amounts of flavorings, is easy to use, and one enables the cigarettes so flavored to be stored for a long time.
• This object is achieved according to the invention in a method of the type mentioned at the outset by using a porous silica gel loaded with flavorings in the mouthpiece of the cigarette.
• a synthetic tobacco flavor a natural one. or synthetic tobacco extract, a natural or synthetic tobacco smoke extract or a phenol ether, for example anethole or anisole.
• silica gel loaded with 16 to 44% by weight, preferably about 30% by weight, based on the unloaded silica gel is used with flavorings or flavorings and deactivating agents.
• a silica gel which, at an equilibrium of 20 ° C. and 50% rela tive air humidity based on the dry substance of the silica gel, 5 to 18 wt .-%, preferably about 8 wt .-% water.
• the silica gel loaded with flavorings is arranged in at least part of a cigarette filter. It is advantageous if the silica gel loaded with flavorings is incorporated into at least part of the filter material intended for a cigarette filter, for example a double filter.
• the present invention further relates to a cigarette end piece, in particular a cigarette filter, for carrying out the method according to the invention, which is characterized in that it has a chamber containing at least the granulate-shaped silica gel loaded with flavorings.
• the present invention also relates to a use of the method according to the invention for the anetholization of tobacco smoke.
• silica gel is used as a carrier and storage material for the anethole, even with a small load of 10% by weight of anethole (based on the weight of the unloaded silica gel), the smoke can be properly flavored if the optimization rule is observed will that the flavoring and deactivating agent together make up about 30% by weight based on the unloaded silica gel. Because e.g. the propylene glycol deactivating agent is significantly cheaper than. Anethol, this is also interesting for cost reasons. When using activated carbon as a carrier and storage material for the anethole, it is impossible to flavor the smoke in any way with 10% by weight of anethole.
• the under standard conditions when smoking cigarettes provided with highly porous chamber filters containing 10% by weight of anethole and 20% by weight of propylene glycol (in each case based on the weight of the unloaded carrier material) containing chamber filters containing nine puffs in the smoke Anethole content present in the particulate phase is determined, shortly after. the loading of the silica gel used and again after about three months, both times an amount of anethole (in particulate phase) of 0.44 mg / cigarette was found.
• the silica gel loaded with a flavoring substance is filled into the chamber of a chamber filter, it is also possible to provide it in a mouth or end part which is closed in the axial direction by means of two end walls, the filter effect of which is negligible, so that, for example, the tar and nicotine content the flowing smoke is practically not changed and thus corresponds to the smoke of a filterless cigarette, but on the other hand the flowing smoke is additionally flavored.
• the silica gel loaded with an aroma substance in the manufacture of a cigarette filter by means of an adhesive between the fibers of the filter material strand.
• the carrier material loaded with flavorings would preferably be arranged in the tobacco part of the filter cigarette adjacent to the plug of the filter.
