Definitions

  • the invention is relating to a tobaccc smoke filte in the form of a filter element, consisting of fibrous or granular filter material, whereby at least a part of the filter element is consisting of biologically active dried yeast, the biologically active cells of which are at least particial ly decomposing and/or converting the hydrocarbons of the tobacco smoke in non-toxic compounds, on account of their own internal metabolism.
  • the taste appraisal may be changed in a negative way, while also the air flow through the cigarette by the smoking operation may be changed.
  • the part of the mixture of biologically active dried yeast in the respective filter elements are depending of the goal aimed at, the types of tobacco and the like, whereby the moisture content of the dried yeast is likewise adaptable.
  • An advantage of such a filter construction wherein a part of the filter material is consisting of a biologically active dried yeast is not only residing in this significant enlarging of the active filter surface (1 g of dried yeast provide 2 m 2 ), but also in the fact that in 1 g of dried yeast there are about 10 milliard of biologically active cell organisms.
  • the hydrocarbons in tobacco smoke are at le ⁇ st particiaily decomposed and or converted in non-toxic compounds, such as carbondioxide.
  • yeast cultures may also be assumed to be possible during the soaking of the tobacco, when pretreated.
  • yeast preparations derived from Sacharomyees cerevisiae may be applied, however, also other yeasts belonging to the genus Torulopsis or to other species of Saccharor ⁇ yces, such as Saccharomyces carlbergensis, Saccharomyces beticus. Saccharomyces rosei, Saccharomyces cheresiensis, Saccharomyces ferment! and Saccharomyces pasteurianus may be applied with good results.
  • yeast preferably biologically active dried yeast is applied, which is regularly available in commercial, i.e. unlimited, amounts against a relatively low cost price pro unity, like e.g. dry yeast derived from Sacharomyees cerevisiae, and which shows a sufficient large internal active surface.
  • the genetic character or the disposition of the yeast cells may be possibly further adapted by suitably selected propagation methods to meet the desired conditions.
  • the preferably applied biologically active dried yeast may be prepared from fresh compressed yeast by a process as disclosed in e.g. the British patent no. 1.230.205, relating to the preparation of dry yeast using preferably a fluidized drying equipment and starting from compressed yeast having a high biological activity.
  • the biologically active dry yeast can be added in an amount of 0.01-0.5 g pro gram of tobacco and preferably in an amount of 0.1-0.2 g pro gram of tobacco. It is true that incorporation to dried yeast to cigarette filters is known from the French patent no. 2.151.814 and from the US patent no. 4.121.599.
  • a tobacco smoke filter including a particulate medium obtained from fungal mycelia and/or yeast.
  • the filter preferably has a cylindrical paper wrapper, while the medium is from the classes Fhycomycetes, Ascomycetes, Fungi Imperfect! and Basidiornycetes, having an average particle size of 125-3300 and being agglomerated with carboxymethylcellulo ⁇ e, glycerol methyl cellulose or corn syrup binder.
  • the haemoglobin is preferably added in an oxidised state and in the form of a dry, colourless preparation, in powder form, which may be obtained according to a process, comprising oxidation of dry haemoglobin by means of oxygen providing compounds, followed by washing of the oxidation product with water and subsequent drying.
  • the dry haemoglobin starting material may be prepared from animal blood sources by methods known in the art.
  • the oxidation of haemoglobin is carried our with hydrogenperoxide, several per compounds or ozone.
  • the oxygen providing agents are used in a concentration between 10 and 30/5 by weight depending on the specific state of dry haemoglobin starting material, the per compounds or ozone to be used.
  • the haemoglobin preparation to be applied according to a preferred emobidiment may be accomodated in one or more of the compartments formed by hollowing out a fibrous filter, according to several construction types as known from the literature beforementioned. More specifically ir ⁇ filter capsules or cartridges for cigarette pipes and tobacco pipes, for instance, the haemoglobin preferably may be mixed with already available filter materials and more particularly biologically active dried yeast as co-ingredient. Preferably the haemoglobin and this dried yeast are applied in a range of weight ratios from 1:2 to 2:1 and more preferably in a weight ratio of about 1:1.
  • the filter materials for cigarettes may be imgregnated with haemoglobin or the haemoglobin may be granulated.
  • Another alternative for carrying out this application of hamoglobin in cigarette filters might be the building in of haemoglobin during the cellformatlon of biologically active dried yeast cells during or after the cultivation, in cases, that biologically active dried yeast is simultaneously incorporated in the filter element and which alternative may be advantageous, having in mind that the filtering action of yeast cells as to nicotine could be detected.
  • dry granulated stimulants and more particularly caffeine containing dry coffee may be included in the filter to improve and/or intensify the taste quality and the flavour of the tobacco smoke, while simultaneously adsorption or binding of harmfull compounds is maintained.
  • dry granulated stimulants and more particularly caffeine containing dry coffee may be included in the filter to improve and/or intensify the taste quality and the flavour of the tobacco smoke, while simultaneously adsorption or binding of harmfull compounds is maintained.
  • such stimulants may be included in the filters of the present invention, by methods known per se and by means of known constructions as indicated hereinbefore.
  • the stimulants such as dry coffee may be mixed up, before incorporation in the filtersystem, with suitable additional filter aids like e.g. biologically active dried yeast, biologically active or soluble milk powder, or with other flavouring agents, which preferably are readily soluble, like e.g. medicinal-pharmaceutical agents.
  • suitable additional filter aids like e.g. biologically active dried yeast, biologically active or soluble milk powder, or with other flavouring agents, which preferably are readily soluble, like e.g. medicinal-pharmaceutical agents.
  • this problem was solved by mixing the filter-substance, containing the biologically active dry yeast, with a matching amount of microcapsules, containing a liquid medium.
  • biologically active dried yeast with an added and matching amount of microcapsules in a filter element in such a way, that at least a. part of the filter element consists of biologically active dried yeast, together with microcapsules.
  • microcapsules are suitably filled with water or a sugar solution of a low concentration, and which burst open during the inhalation of tobacco smoke through the filter. In this way the liquid suddenly will activate the biologically active dried yeast, due to the preferred nutrient supply.
  • the bursting of the microcapsules may be reached on the one hand by means of osmotic adaptation in the filter element by sucking on the tobacco smoke or on the other hand by means of a slight finger press on the filter element before smoking a cigarette.
  • microcapsules are known on their own and may be prepared e.g. according to methods disclosed in US patents nos. 3.494.505, 3.503.783, 3.516.846, 4.201.404 and 4.225.460, British patents nos. 2.021.512 and 1.370.282 and Dutch patent no. 135.125. However, the presently proposed use of such microcapsules is nowhere disclosed or even suggested.
  • the filter components may be arranged in successive compartments of a filter element.
  • microcapsules containing a suitable liquid medium, may also be incorporated in the filter element as such, in order to achieve a cooling of the smoke gasses and/or humidification of the tobacco.
  • microcapsules also may be filled with other liquids and compounds, which are subservient to the filtering and/or flavouring of tobacco smoke. They can also constitute an independent filter element.
  • FIG. (2) By the way of example a specific prefered embodiment of the present invention may be illustrated by means of the figure (2), showing a transverse section of a cigarette with tobacco filling (1) and connected filter tip (2), wherein a shortened, fibrous filter material (3) and the arranged biologically active dried yeast as filtering agent (4) with the included microcapsules (5).
  • cigarette A a Peter Stuyvesant® cigarette with a normal filter construction, without any addition.
  • cigarette B the same cigarette, with biologically active yeast, which was previously brought on the humidity of the tobacco, (dry matter content 9 4% ) , incorporated in the filter, in a total amount of 0.2 g.
  • cigarette C the same cigarette, but with biologically active yeast and haemoglobin in equal amounts and in a total amount of 0.2 g.
  • cigarette D the same cigarette, containing biologically active yeast and oxidized haemoglobin in equal amounts and in a total amount of 0.2 g.
