Definitions

  • the invention relates to a new product, a clear tobacco aroma oil, free of polyphenols, resins and waxes, with a reduced (reduced) nicotine content of 5 to 50% relative (based on the tobacco from which the tobacco aroma oil originates) and with which the typical tobacco smell used in each case.
  • the invention relates to a method for separating clear tobacco aroma oil from tobacco extract and its use according to the claims.
  • the flavoring of tobacco plays a special role in the manufacture of tobacco products. Attempts to partially or wholly obtain the tobacco aroma oil typical of the respective tobacco from aroma-strong tobacco or tobacco waste in order to add it to other, low-aroma tobacco of the same provenance have so far failed because an absolute (clear) tobacco aroma oil free of resins and waxes with reduced nicotine content.
  • DE-OS 21 28 779 describes a process for the production of flavorings and the. Conversion of aroma precursors from tobacco, by extracting the tobacco with one or more solvents which are in the eluotropic range between trichlorethylene and ethyl acetate and activating the aroma precursors from the extract obtained by heat treatment between 110 and 180 °.
  • the aroma products obtained by this process represent a wax-like, resinous mass which contains all waxes and resins as well as polyphenols and almost all nicotine of the starting product.
  • DE-OS 21 42 205 describes a process for the selective, aroma-preserving extraction of nicotine from tobacco, - in the first stage of which the aroma is extracted from the dry tobacco by treatment with dry, supercritical gases (for example CO 2 ), which is then temporarily removed from the Separation container B remains until the tobacco in container A has been removed from the nicotine by a second process stage with the help of moist CO 2 , which is then separated out in container D.
  • the flavoring substances in container B are dissolved with, for example, supercritical CO 2 , returned to container A and deposited there on the tobacco.
  • This process is expensive in terms of tobacco aroma extraction and exploitation and is inefficient because the product obtained in the first stage is not a clear liquid tobacco aroma oil that can be separated from resins and waxes, but is a paste that contains almost all undesirable waxes and resins of the starting product and undesirable ones Includes polyphenols.
  • these wax and resinous substances prevent the even distribution and aroma transfer when rearomatizing a tobacco to be loaded.
  • One of the disadvantages of the polyphenols is that they impair the smoky taste.
  • DE-OS 28 44 781 describes a method for the extractive treatment of plant and animal material, i.a.
  • the object of the present invention is to obtain a clear, absolute tobacco aroma oil which contains almost all the aroma substances of the starting product qualitatively and quantitatively, is free from resins, waxes and polyphenols and whose nicotine content - compared to the starting product - is greatly reduced.
  • tobacco is fermented tobacco leaves, stems, stems or dust, and tobacco waste.
  • tobacco primary extract is an ethyl acetate with customary organic solvents, in particular benzene, toluene, methanol, ethanol, n-propanol, methyln-propane, diethyl ether, acetone, n-propane, n-hexane, cyclohexane, petroleum ether, dichloromethane or Trichloromethane, or extract made with mixtures of these solvents.
  • a primary extract according to the present invention further provides a C0 2 extract, that is, with the aid of CO 2 produced as a solvent extract.
  • Adsorbents for the purposes of the present invention are all common adsorbents, in particular activated carbon, aluminum oxide, magnesium oxide, sodium aluminum silicate, bleaching earth, bentonite, silica gel, diatomaceous earth, zeolitic molecular sieves etc.
  • Tobacco aroma oil in the sense of the present invention is an absolutely clear, tobacco aromatic, oily liquid at normal temperature - free of resins and waxes, free of polyphenols, with a reduced nicotine content of 5 to 50% relative (in particular 10 to 40% relative) based on the tobacco from which the tobacco extract originates - which shows no clouding or precipitation when 95% by weight ethanol is added.
  • the preparation of the tobacco primary extract used according to the invention consists in particular in extracting the tobacco in one of the abovementioned solvents or (in the case of organic solvents) in a solvent mixture.
  • 1 part by weight of pre-shredded tobacco is preferably extracted with about 3 to 30 parts by weight of one of the solvents mentioned (preferably CO 2 , n-hexane or dichloromethane).
  • the primary extraction takes place for at least 10 minutes and at most 10 hours, preferably for 1 to 5 hours.
  • the primary extraction takes place under normal pressure conditions. If organic solvents are used, the primary extraction takes place under normal pressure conditions. If CO 2 is used in the primary extraction, the pressure and temperature conditions in the extraction container and separating container, as well as the extraction time and CO 2 flow rate are identical to those specified below in connection with the (single-stage) secondary extraction (see page 10, Lines 5 to 19, page 11, lines 12 to 32).
  • the evaporation is preferably carried out under reduced pressure, particularly preferably at about 15 torr. If C0 2 is used, the evaporation takes place in the separating container, as already explained above, under the pressure and temperature conditions as specified below for the (single-stage) secondary extraction.
  • a tobacco primary extract obtained in this way contains, among other things. Polyphenols, resins / waxes, nicotine and, as the inventor has determined, is in an easily accessible form which is particularly suitable for the subsequent secondary extraction (with CO 2 ),
  • the tobacco primary extract obtained is now according to the invention. mixed intensively with an adsorbent until there is an even distribution between extract and adsorbent.
  • Particularly preferred adsorbents are: sodium aluminum silicate, bentonite, magnesium oxide or zeolitic molecular sieves.
  • the mixing ratio of extract: adsorbent is variable and can be adjusted depending on the consistency of the extract, the density and particle size of the adsorbent and the desired consistency of the mixed product. In general, a mixture ratio of extract: adsorbent between 1: 0.1 to 1:10 is sufficient; preference is given to a powdery extract mixture with an extract: adsorbent mixing ratio of 1: 0.3 to 1: 6.
  • the extract / adsorbent mixture should not fall below the ratio 1: 0.1, because the adsorbent used according to the invention, the dissolving of the flavoring substances in the subsequent secondary extraction with CO 2 (in the extraction container) and the separation in the separating container as clear absolute, easily separable from resins and waxes Tobacco aroma oil significantly influenced.
  • a mixture ratio of more than 1:10 also gives a good detachment and separation of the tobacco aroma oil, although a larger pressure vessel volume has to be accepted.
  • the mixture of primary extract and adsorbent is' in a first pressure vessel (extraction vessel), preferably high pressure vessel, with CO 2 under certain pressure and Treated temperature conditions until all the aromas are present in the second pressure vessel (separator vessel) downstream of the extraction vessel as an oily liquid that can easily be separated from resins and waxes.
  • extraction vessel preferably high pressure vessel
  • second pressure vessel separator vessel
  • This secondary extraction with C0 2 by the method of the invention is achieved by supercritically using the C0 2 used for extracting the extract / adsorbent mixture with respect to pressure and temperature (> 73 bar and> 31.3 ° C) or with respect to Keeps pressure and temperature subcritical ( ⁇ 73 bar and ⁇ 31.3 ° C) or supercritical with regard to pressure (> 73 bar) and subcritical with regard to temperature ( ⁇ 31.3 ° C).

  • pressures from 85 to 200 bar and temperatures from + 10 ° C to + 30 ° C are preferred.
  • an additional CO 2 extraction step can be carried out at a lower level between the claimed primary extraction and the claimed secondary extraction Temperatures are interposed.
  • the extract obtained in the primary extraction and mixed with the adsorbent is treated beforehand at CO 2 extraction temperatures from -25 ° C. to + 5 ° C.
  • nicotine and other secondary alkaloids are almost exclusively dissolved out of the primary extract / adsorbent mixture and in the separation container eliminated.
  • the nicotine obtained is removed from the separation container before the subsequent secondary extraction (aroma extraction) with CO 2 begins.
  • the separation conditions in the expansion tank are decisive for the quality and quantity of the product obtained according to the invention.

Pressures of 45 to 65 bar and temperatures of 15 to 30 ° C are preferred; pressures of about 50 to 55 bar and temperatures of 20 to 25 ° C. are particularly preferred.
  • the separation in the expansion tank is preferably carried out with simultaneous pressure and temperature lowering than the pressure and temperature conditions prevailing in the extraction tank .;
  • the amount of CO 2 flowing through the extraction container and the duration of the flow are also decisive for the procedure according to the invention.

  • a total amount of CO 2 is expedient from 0.3 to 35 kg / hour, preferably 3 to 30 kg / hour, particularly preferably 5 to 15 kg / hour, based on 1 kg of untreated tobacco.
  • a special characteristic of the tobacco aromatic oil obtained according to the invention is also that it has the tobacco smell typical of the starting tobacco used in each case. This characteristic clearly distinguishes it from all tobacco extracts known to date, because none of the conventional tobacco extracts made it possible to produce the typical smell of the respective starting tobacco. Based on this characteristic feature of the tobacco extract obtained according to the invention, it can be assumed that its material composition is completely new compared to the prior art.
  • the tobacco flavor is separated and obtained as a clear and absolute oil, and this. with measures that are easy to carry out and a particularly efficient result. No indication of the prior art could be found either for this process as such or for the product obtained.
  • the tobacco constituents which are obtained by primary extraction according to the procedure according to the invention, behave in a mixture with a powdery adsorbent and subsequent secondary extraction (with C0 2 ) with respect to their viscosity, their solubility and separation ratios very different from the same Ingredients that are only subjected to primary extraction (including CO 2 primary extraction), e.g. from tobacco leaves.
  • Aroma oils obtained in a conventional manner were only produced by steam distillation on a laboratory scale.
  • the oils obtained were of numerous foreign smells, e.g. Accompanied by chamomile, caraway, peppermint, valerian and amyl alcohol, which are probably caused by artifacts.
  • the yield of such tobacco oils was about 0.1 to 0.2%.
  • the tobacco aroma oil obtained according to the invention which has the typical and pure smell of the starting tobacco used in each case, stands in clear distinction from this. This is how it smells, for example the Havana tobacco flavored oil obtained from Havana tobacco, the Kentucky tobacco flavored oil obtained from Kentucky tobacco. In a similar way, aromatic oils obtained from Virginia, Orient or Burley tobacco show the very typical and pure smell of the respective tobacco variety. Because of this particular characteristic, which is clearly different from the prior art, it should be noted that the tobacco aromatic oil obtained according to the invention is completely new in its material composition compared to the products of the prior art.
  • the tobacco aromatic oil obtained in the manner according to the invention is free from foreign odors, free from polyphenols, resins and waxes, has a reduced nicotine content which is only 5 to 50% relative to the tobacco leaves used, and is obtained in yields of 0.8 to 2%. Get 5% (absolute oil).
