Definitions

  • the invention relates to a method for aromatizing tobacco smoke extracted from a cigarette by means of a silica gel arranged in the mouthpiece of the cigarette and loaded with flavorings, a cigarette end piece, in particular cigarette filter, for carrying out the method, and a use of this method.
  • silica gel as a flavoring substance carrier has the disadvantage that for a really good flavoring of tobacco smoke extracted from a cigarette, on the one hand a great deal of the mostly very expensive flavoring material is required because of the high adsorption capacity of the silica gel, and on the other hand the storage capacity is unsatisfactory given the high aroma loads required for this As an important point in practice, the aroma delivery to the warm and humid flue gas stream flowing past the silica gel loaded with the aroma substance is too uneven over the smoking time of the cigarette.
  • the object of the present invention is to provide a method for aromatizing tobacco smoke sucked from a cigarette, when used on the one hand during storage of the cigarettes or. of the silica gel loaded according to the invention, practically no aroma substance is undesirably released into the environment, so that only a minimal amount of the usually very expensive aroma substance is required, and on the other hand, during the smoking of such a flavored cigarette, this aroma substance is very evenly and practically completely passed on to the entire period of smoking flowing wet and flue gas flow is released.
  • This object is achieved according to the invention in a method of the type mentioned at the outset by adjusting the adsorbability of the highly porous silica gel to a desired value with the aid of propylene glycol which acts as a deactivating agent.
  • the aroma carrier thus loaded with aroma substances is in a warm and moist flue gas stream of a cigarette, then with each pull of the smoker on such a cigarette, as desired, a certain relatively uniform amount of aroma substance is released to the flowing warm and humid flue gas stream.
  • a synthetic tobacco aroma a natural or synthetic tobacco extract, a natural or synthetic tobacco smoke extract or a phenol ether, for example anethole or anisole, is used as the aroma substance.
  • silica gel which, at an equilibrium of 20 ° C. and 50% relative atmospheric humidity, based on the dry substance of the silica gel, contains 5 to 18% by weight, preferably about 8% by weight, of water.
  • the weight of the dry silica gel is determined by exposing the moisture-laden silica gel to a temperature of 160 ° C. until the weight of the silica gel remains constant and then determining its dry weight.
  • the silica gel laden with flavorings is arranged in at least part of a cigarette filter. It is advantageous if the silica gel loaded with flavorings and propylene glycol is incorporated into at least part of the filter material intended for a cigarette filter, for example a double filter.
  • the present invention also 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 granular silica gel loaded with flavorings and propylene glycol.
  • the present invention also relates to a use of the method according to the invention for the anetholization of tobacco smoke.
  • the chamber filters were provided under standard conditions when smoking with a highly porous, containing 10 wt .-% anethole and 20 wt .-% propylene glycol wt .-% (each based on the weight of the unloaded carrier material) Cigarettes in nine puffs of smoke in the particulate phase determined the presence of anethole, shortly after loading the silica gel used and again after about three months, both times with an amount of anethole (in particulate phase) of 0.44 mg / cigarette.
  • the silica gel loaded with a flavoring agent and propylene glycol 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 and propylene glycol would preferably be arranged in the tobacco part of the filter cigarette next to the plug of the filter.
