    Ce tabac découpé en scaferlati a été fumé par des panélistes dans un système de chauffage Pax réglé à 199°C, en introduisant dans la chambre de chauffage 250 mg de tabac.
    Les panélistes ont relevé que pour les 5 essais, le volume de fumée et la consistance de la fumée étaient satisfaisants et que goût tabac était également satisfaisant, mais que les essais A et D présentaient certes le goût tabac, mais étaient plus irritants en gorge et piquants en bouche que les autres essais, avec une note brûlée, un arrière gôut empâtant et pas propre.
    The invention relates to a reconstituted tobacco for devices heating the tobacco without burning it.
    The phenomena of combustion and pyrolysis of tobacco within the cigarette lead to the formation of many harmful constituents in the smoke. In order to prevent their formation, a large number of smoking devices have been developed. Examples that may be mentioned include the applications published under the numbers WO2013 / 178769 and EP2644043 which describe such devices. In these devices, the tobacco is heated without being burned, which leads to the formation of an aerosol. This allows the smoker to inhale the aromas of tobacco while significantly reducing its exposure to harmful constituents.
    For such devices, conventional tobacco is not suitable. Indeed, it is necessary to add to tobacco a significant amount of humectants, such as glycerin or propylene glycol to generate an aerosol when heating tobacco. It is this aerosol that replaces cigarette smoke and where nicotine and tobacco flavors are found. The tobacco for the heating devices may be in the form of a tobacco rod or a capsule or pouch containing scaferlati cut tobacco or coiled or creped leaf or tobacco powder. To avoid variations in the quality of tobacco, it is very important that the tobacco be homogeneous, which is not easy to obtain in the case of a mixture of natural tobacco.
    The inventors have developed a reconstituted tobacco specifically adapted for devices heating the tobacco without burning it. This reconstituted tobacco is very homogeneous and has good organoleptic qualities. This reconstituted tobacco when heated generates, in particular, an aerosol which is not very irritating in the throat and has a slight pungency in the mouth and has no burnt tobacco notes.
    The present invention describes a reconstituted tobacco comprising: - tobacco fibers; a soluble aqueous fraction of tobacco; and - a humectant, wherein: the soluble aqueous fraction of tobacco represents between 10 and 35% by weight of the reconstituted tobacco dry matter; and the humectant represents between 8 and 50% by weight of the reconstituted tobacco dry matter.
    Typically, the tobacco fibers represent between 30% and 80% of the dry weight of the reconstituted tobacco.
    Typically, the tobacco fibers represent between 70% and 100% by weight of the fibers constituting the reconstituted tobacco.
    Typically, the remaining fibers are vegetable cellulosic fibers obtained by a chemical or mechanical or thermomechanical cooking process such as wood pulp or annual plants such as flax or tobacco for example. A mixture of these cellulosic plant fibers can also be used.
    Reconstituted tobacco can be obtained from any type of tobacco (eg from Virginia tobacco, Burley tobacco, air-cured tobacco, dark air-cured tobacco, Oriental tobacco, sun-cured tobacco, fire-cured tobacco or tobacco mixtures). Typically, reconstituted tobacco results from the treatment of different types of tobacco.
    Typically reconstituted tobacco results from the transformation of different parts / tissues of the tobacco plant and its transformation. Typically, reconstituted tobacco results from the treatment of tobacco leaves or tobacco debris from threshing or mixing and smearing of tobacco leaves and ribbons. Typically the reconstituted tobacco will be obtained from tobacco parenchyma (lamina) optionally added with stems (stems) of tobacco.
    The soluble aqueous fraction of tobacco corresponds to all tobacco products that are soluble in water. To determine the percentage by mass of the soluble aqueous fraction of tobacco, the following method may be used:
    The tobacco to be analyzed is milled to reach a particle size less than or equal to 1 mm. The milled tobacco is then mixed with boiling water for 45 minutes to extract all of the soluble aqueous tobacco fraction. The weight of soluble aqueous fraction of tobacco is calculated by difference between the dry weight of the tobacco sample and the dry weight of the fibrous residue after extraction.
    Let S be the percentage by weight of dry matter in the reconstituted tobacco of the soluble aqueous tobacco fraction, Smin <S <Smax, the percentages Smin and Smax are chosen independently of one another, Smin being chosen from among the values 10% and 15%, and Smax being chosen from the values 20%, 25%, 30%, 35%, preferably Smin is equal to 15% and Smax is 30%.
    According to a particular embodiment, the percentage S is approximately 15%, 17% or 21%.
    It is important to control the weight percentage of the soluble aqueous fraction of the reconstituted tobacco, since the level of this fraction depends in part on the organoleptic properties of the reconstituted tobacco. In addition, beyond 35%, the aerosol generated during the heating of reconstituted tobacco becomes too irritating in the throat, spicy in the mouth and with burnt tobacco notes.
    Let P be the percentage by weight of dry matter in the reconstituted humectant tobacco, Pmin <P <Pmax, the percentages Pmin and Pmax are chosen independently of one another, Pmin being chosen from the values 8%, and 10%, and Pmax being selected from the values 20%, 25%, 30%, 35% and 40%, preferentially Pmin is equal to 12% and Pmax 25%.
    According to a particular embodiment, the percentage P is approximately 17%.
    According to one embodiment the humectant is glycerine, propylene glycol or a mixture of glycerine and propylene glycol.
    According to a preferred embodiment, the humectant used is glycerine.
    Many methods of reconstituting tobacco are known for making reconstituted tobacco, for example papermaking processes, pulp display and baking processes or extrusion processes.
    According to a preferred embodiment of the invention, use will be made of a papermaking process for reconstituting tobacco.
    According to this embodiment, a reconstituted tobacco according to the invention is a reconstituted tobacco that can be obtained by a papermaking process.
    One embodiment relates to a papermaking process for the manufacture of a reconstituted tobacco, comprising the following steps: parts of tobacco from the threshing or chopping of the leaves are mixed with water in order to extract the water-soluble products from the tobacco ; the water-soluble products are then separated from the tobacco fibers; the tobacco fibers are refined and passed through a paper machine to form a base sheet; the water-soluble tobacco products obtained during the extraction are concentrated; all or part of the concentrated hydrosolubles are incorporated with a humectant in the base sheet to form a reconstituted tobacco sheet according to the invention.
    A particular embodiment relates to a papermaking process for manufacturing a reconstituted tobacco, comprising the following steps: a part of the tobacco materials originating from threshing or chopping the leaves are mixed with water in order to extract the products water soluble tobacco. This part includes tobacco materials selected from tobacco fabrics richest in precursors of aromatic compounds to enhance the sensory quality of the aerosol during heating. The water-soluble products are then separated from the tobacco fibers and concentrated; the other part of the tobacco material from the threshing or chopping of the leaves is mixed with water in order to extract the water-soluble products from the tobacco; these water-soluble products are then discarded. This part comprises tobacco materials selected from the tobacco fabrics the poorest in precursors of aromatic compounds; the tobacco fibers of both parts are mixed, refined and passed through a paper machine to form a base sheet; all or part of the concentrated hydrosolubles are incorporated with a humectant in the base sheet to form a reconstituted tobacco sheet according to the invention.
    Typically, the tobacco parts from the threshing or chopping of the leaves are collected and after calibration, mixed with water, for example in a digester, to extract the water-soluble products of the tobacco. The water-soluble products are then separated from insolubles consisting essentially of tobacco fibers, for example, by passing the paste obtained in a screw press. In such a papermaking process, insoluble products are thus dissociated from the soluble products in order to treat them separately.
    Typically the temperature of the water for extraction is between 30 ° C and 90 ° C, for example between 30 ° C and 70 ° C or between 50 ° C and 90 ° C. Typically, the temperature of the water can be adapted to the material to be treated. Typically for the treatment of ribs / tobacco ribs, the temperature of the water for extraction may be between 50 ° C and 90 ° C, for the treatment of tobacco parenchyma (lamina), the temperature of the water for the extraction may be between 30 ° C and 70 ° C.
    The fibers pass, for example, in a refiner before going into a paper machine to form a sheet of tobacco fiber or base sheet.
    Typically, the water-soluble tobacco products obtained during the extraction are concentrated, for example, in a vacuum evaporation device, before being incorporated in whole or in part with the humectant in the base sheet to form a reconstituted tobacco leaf.
    Typically, additives, such as for example flavorings, may be incorporated into the base sheet.
    The amount of water-soluble products incorporated into the base sheet will depend on the percentage of the desired soluble aqueous fraction for the reconstituted tobacco.
    According to a preferred embodiment of the invention, the extraction step will be carried out firstly on parenchyma of tobacco and secondly on ribs and tobacco ribs and only the water-soluble products obtained during the treatment. extraction step performed on tobacco parenchyma will be incorporated into the base sheet.
    The reconstituted sheet is then treated in a drying device.
    This reconstituted tobacco leaf can then be cut into sheets, sheets similar to tobacco strips or rolled into rolls which will then be cut into coils of reconstituted tobacco or crushed into dust. Several leaves can be assembled to form a composite of leaves. Typically, the reconstituted tobacco according to the invention can be shaped into sheets, crepe sheets, multi-layer sheets, leaflets, coils, dust, or crepe rolls. EXAMPLES Example 1
    A mixture of Virginia Tobacco Tobacco, Burley, Orient is brought into contact with water in the laboratory in a 40 ° C water bath with manual agitation for 30 minutes. The soluble aqueous fraction is separated from the fibrous portion by mechanical pressing. Its concentration in dry matter is of the order of 5%. The soluble aqueous fraction is concentrated under vacuum to a dry matter concentration of 47%. Glycerine is added to the soluble aqueous tobacco fraction to provide about 20% by weight in the final reconstituted tobacco.
    In parallel, Virginia tobacco ribs are contacted with water in a water bath at 80 ° C for 30 minutes. The soluble aqueous fraction is separated from the fibrous portion by mechanical pressing and is discarded.
    The lamina fibers and the tobacco rib fibers, added with water and 10% wood cellulose pulp, expressed in% by weight of the extracted tobacco mixture are mixed and transferred to a refiner. The fibers are refined for about 20 minutes.
    A tobacco fiber sheet is formed on a laboratory paper machine with a basis weight of about 75g / m2. Glycerine is added to the concentrated soluble aqueous fraction. The soluble aqueous fraction of concentrated tobacco comprising the glycerine is added to the tobacco fiber sheet by impregnation in a press size to reach a final weight of 109 g / m 2. The sheet thus obtained is dried and cut into scaferlati.
    The reconstituted tobacco thus obtained contains 18.8% of glycerin (analysis carried out by gas chromatography (GC)), 0.34% of total alkaloids, 3% of reducing substances and 0.14% of nitrates, all three by flow. continued. The soluble aqueous fraction of tobacco represents 11.8% by weight of the reconstituted tobacco dry matter. All percentages are by weight of dry matter.
    This tobacco cut into scaferlati is frimbled in a heating system Pax Ploom Inc. / Pax Labs Inc set at 210 ° C, by introducing into the heating chamber 250 mg of tobacco. The panelists note slight notes of Virginia tobacco hay type, tea, a slight sweetness and highlight the low irritation, especially in the throat, giving the sample a certain sensory neutrality.
    Example 2
    A Virginia Tobacco Tobacco Lamina blend, Burley, Orient, is contacted with water in the laboratory in a 85 ° C water bath with hand shaking for 30 minutes. The soluble aqueous fraction is separated from the fibrous portion by mechanical pressing. Its concentration in dry matter is of the order of 7%. The soluble aqueous fraction is concentrated in vacuo. Glycerine is added to the soluble aqueous tobacco fraction to obtain between 13 and 18% by weight in the final reconstituted tobacco.
    The tobacco fibers, added with water and 8% wood cellulose pulp, expressed in% by weight of the mixture of extracted tobacco, are mixed and transferred to a refiner. The fibers are refined for about 17 minutes.
    A sheet of tobacco fibers is formed on a laboratory paper machine. Glycerine is added to the concentrated soluble aqueous fraction. The soluble aqueous fraction of concentrated tobacco comprising glycerine is added to the tobacco fiber sheet by impregnation in a press-size. The sheet thus obtained is dried and cut into scaferlati.
    The reconstituted tobacco thus obtained contains from 13 to 18% of glycerin (analysis performed by gas chromatography (GC)). The soluble aqueous tobacco fraction varies between 15 and 40% as indicated below. All percentages are by weight of dry matter.
    This tobacco cut into scaferlati was smoked by panelists in a heating system Pax set at 199 ° C, by introducing into the heating chamber 250 mg of tobacco.
    Panelists noted that for the 5 trials, the smoke volume and consistency of the smoke were satisfactory and that the tobacco taste was also satisfactory, but that the A and D tests did taste good, but were more irritating in the throat and prickly in the mouth than the other tests, with a burnt note, a back taste impassive and not clean.
