Definitions

  • Aerosol-generating tobacco-containing composition comprising medium- chain triglyceride
  • Such devices include for example electrically heated aerosol-generating devices in which an aerosol is generated by the transfer of heat from a heating element of the aerosol-generating device to aerosol-generating substrates or materials.
  • Tobacco material which has been homogenised is often used in the production of tobacco products. Parts of tobacco plants that are less suited for the production of cut filler such as tobacco stems or tobacco dust are typically materials used for homogenised tobacco material. Examples of common forms of homogenised tobacco material are for example powder form, reconstituted tobacco sheet and cast leaf.
  • aerosol-forming substrate is heated at a rather relatively low temperature, for instance below 350 °C, to avoid combustion thereof.
  • a charge of inhalable aerosol can then be released from the aerosol-generating article.
  • the aerosol released is originated from the aerosol formers, which are incorporated into the tobacco material, which may be particulated or granulated.
  • these aerosol formers have to be migrated from within the body of the homogenised tobacco material to surfaces of the homogenised tobacco material.
  • other volatile compounds such as nicotine migrate in a similar fashion outwardly from the body of the homogenised tobacco material, and eventually be released in the charge of aerosol.
  • WO 2017/077112 A1 relates to a homogenised tobacco material comprises tobacco and lipid having a melting point between 50 °C and 150 °C. It was disclosed therein that homogenised tobacco material comprises the meltable lipid component advantageously allow less tobacco to be used while providing an equivalent nicotine or aerosol yield. Moreover, the inclusion of the meltable lipid component also allows the migration of aerosol-formers and other volatile compounds within the homogenised tobacco material to the surface area of the tobacco material. Nevertheless, these advantages come in the expense of the fact that side-tastes and off odours resulted from the meltable lipid component cannot be completed avoided.
  • a first aspect of the invention is accordingly to provide an aerosol generating tobacco-containing composition provided in form or a foam or a mousse, wherein the composition comprises particulate tobacco material and lipid, wherein the lipid is medium-chain triglyceride, the ratios of the medium- chain triglyceride to the tobacco-containing material on a dry weight basis are between 1:3 and 1:5.
  • a second aspect of the invention is accordingly to provide an aerosol generating article comprising the aerosol-generating tobacco-containing composition provided in form or a foam or a mousse according to the present invention.
  • a third aspect of the invention is accordingly to provide a method of preparing an aerosol-generating tobacco-containing foam or mousse, comprising the steps of: (a) Mixing an aerosol-forming agent, a foam-forming agent and optionally a solvent, under heating; (b) Aerating the mixture with a gas or air for at least 5 minutes under room temperature; (c) Adding to the mixture a tobacco- containing ingredient and/or inhalable agent; (d) Optionally aerating the mixture with a gas or air; (e) Adding to the mixture a medium-chain triglyceride, wherein the ratios of the medium-chain triglyceride to the tobacco-containing material on a dry weight basis are between 1 :3 and 1 :5; (f) Aerating the mixture with a gas or air for at least 5 minutes under room temperature; (g) Adding a foam stabilizing agent.
  • the inventors of the present invention have found out that the aerosol generating tobacco-containing composition, more prominently when being provided in form of a foam or mousse, unexpectedly solves the problem of side- tastes and off odours of the homogenised tobacco material where lipids are being used.
  • the inventors found out that medium-chain triglyceride (MCT) is a better option to be mixed with the homogenised tobacco material compared to lipid, as the MCTs are highly regarded for their clean organoleptic quality. They are odourless and tasteless; hence they do not contribute any off-notes to products.
  • MCT medium-chain triglyceride
  • MCTs are less than 20 % by weight from the total weight on a dry weight basis, regardless of the final amount of the tobacco- containing material, these effects (porosity and fluffiness of the composition and stronger tobacco flavour (e.g. when in form of a mousse or a foam) as mentioned above have not been optimal, as fewer volatile compounds are being released along with the charge of aerosol.
  • the stronger tobacco flavour and aroma obtained in this invention is attributed to the MCTs.
  • MCTs are widely used in the flavour industry because of their superior organoleptic quality and solvent capabilities. Moreover, MCTs is also superior in extracting flavouring. Most probably for this reason, higher percentage of MCTs i.e.
  • the ratio between MCTs and tobacco-containing material is at least 1 :5 but less than 1 :3, the stronger tobacco aroma and flavour can instantly be noticed by the consumer when in use, as these ratios of the MCTs to tobacco has good porosities in the end products such that higher amount of volatile compounds from the aerosol-generating substrate can be released along with the charge of aerosol.
  • the aerosol-generating tobacco-containing composition as claimed presently generally has a micropore size of less than 2 nm and the general fluffiness of the composition is between 1-3 g/cm 3 Thanks to these features of the composition, the aerosol-generating article comprising these compositions are immediately distinguishable from others and hence are preferred choice.
  • the ratio of the medium-chain triglycerides to tobacco-containing material on a dry weight basis is 1:3. This embodiment is most preferred as the volatile compounds such as nicotine delivery rate is found to be the highest compared to all other samples having different ratios.
  • the inventors of the present invention have found out that when the ratio of MCTs and tobacco-containing material on a dry weight basis is 1:3, the porosity and texture of the aerosol-generating materials of the end products is in an optimal condition (e.g. a mixture of open pored foam and closed-cell foam) to have most of the volatile compounds released in the aerosol.
  • the composition is provided in form of a foam or a mousse.
  • the volume of the porous microstructure of the foam is enhanced by the usage of MCTs, especially when the ratio of MCTs and tobacco-containing material on a dry weight basis is 1 :3.
  • foam-forming agent and the foam-stabilizing agent are involved in the formation of the foam as well as maintaining of the foam microstructure.
  • the present invention in form of a foam or a mousse can be applied in all other embodiments discussed herein.

  • the volume of the porous microstructure of the foam can be enhanced by the usage of MCTs under such temperature.
  • the aerosol-generating tobacco- containing composition comprising the medium-chain triglyceride is aerated for at least 5 minutes, preferably at least 10 minutes, under room temperature.

  • the term “medium-chain triglyceride” is used to define an oil comprising one or more triglycerides, each triglyceride having two or three fatty acid chains having a chain length of between 6 and 12 carbon atoms.
  • the fatty acid chain may therefore include one or more of caproic acid (C6), caprylic acid (C8), capric acid (C10) and lauric acid (C12). These can be present in the medium-chain triglyceride oil in any combination and in any relative amounts, provided the required properties of the medium-chain triglyceride oil are obtained.
  • the three fatty acid chains may have the same length as each other or a different length, provided at least two of the fatty acid chains has a chain length of between 6 and 12 carbon atoms.
  • the three fatty acid chains may be identical, or two or more of the fatty acid chains may be different to each other.
  • the triglycerides may individually be saturated or unsaturated.
  • the term “homogenised tobacco material” encompasses any tobacco material formed by the agglomeration of particles of tobacco material, along or in a mixture with other plant materials.
  • the homogenised tobacco material may be provided in granulated (powder) form, or it can be provided as sheets or webs of homogenised tobacco material by agglomerating particulate tobacco material obtained by grinding or otherwise powdering of one or both of tobacco leaf lamina and tobacco leaf stems.
  • homogenised tobacco material may comprise a minor quantity of one or more of tobacco dust, tobacco fines, and other particulate tobacco by-products formed during the treating, handling and shipping of tobacco.
  • the homogenised tobacco material may also be provided in small particle size e.g. less than 100 pm such as claimed presently, and subsequently be used to constitute for the aerosol-generating material, which can be in form of a foam or a mousse.
  • An aerosol-forming agent can be any compound, mixture and/or solution that is capable of forming an aerosol, e.g. when heated and/or in mixture with a tobacco ingredient containing agent.
  • Well known examples include humectants such as glycerin and propylene glycol, other alcohols, such as ethanol, etc.
  • An open pored foam as used herein is to be understood as a foam which can be considered as being formed of a plurality of interconnecting pores (formed out of a structural material derived from the foam forming agent cooperating with the interacting components such as the foam stabilizing agent, solid components such as tobacco particles and some solvent, etc.) which are able to contain fluid, in particular a mixture of humectant/liquid aerosol-forming substrate and air, wherein at least a significant portion (e.g. greater than 50% by volume) of the pores in the foam are fluidly connected with each other, contrary to a closed-cell foam, wherein the majority of the pores form discrete pockets, each completely enclosed by pore-forming material so as to substantially prevent fluid from passing freely between pores.
  • the mousses formed as described herein are largely open-pored mousses because after cooling or heating of the aerosol-generating material comprising the MCTs, vapour is released from the mousse, substantially all of the humectant appears to be released based on measuring of the weight of the mousse portion before and after heating, which could not be readily explained if the humectant was not able to travel through neighboring pores to reach the surface of the mousse portion.
  • alternative explanations cannot be totally excluded - for example closed pores could perhaps be opened by rupturing a closed cell wall as a result of the pressure of vaporized gas, etc.
  • An electronic cigarette (e-cigarette) or similar devices like electronic pipes or heat-not-burn devices, as referred to in the present invention, are not particularly limited, and may be used to provide a user with an aerosol to inhale. It can, according to certain embodiments, comprise a mouthpiece, a heater, a receiving portion, e.g. a pod, stick, capsule and a casing.
  • melting point refers to the clear point or complete melting point of the medium-chain triglyceride. This corresponds to the temperature, in degrees Celsius, at which the oil is fully liquid and completely clear with no solid particles remaining. Many methods known in the art can be used to measure the clear point melting point of an oil, for example, the capillary technique or Stuart SMP50 melting point apparatus.
  • wt.-% is to be understood as weight percent, based on the total weight of the substance on a dry basis, unless explicitly otherwise specified. In the present disclosure, all amounts are given in wt.-%, unless clearly stated otherwise or obvious from context.
  • Present invention relates to an aerosol-generating a tobacco- containing composition, comprising a lipid in form a medium-chain triglyceride (MCTs) oil.
  • the composition can be provided in many forms such as one or more sheets of homogenised tobacco material or be provided in form of a foam or a mousse or powder, wherein the ratios between the MCTs and the tobacco- containing material on a dry basis is between 1 :3 and 1 :5. It is emphasized herein that the present invention is not restricted in these two forms, other forms such as powder form, gel, or coating the aerosol-generating material of the present invention on a carrier would also be possible.
  • the homogenised tobacco material therefore includes the MCT oil in liquid form dispersed within a matrix (solid or semi-solid such as foam or gel) of the tobacco-containing material.
  • the MCTs used in the present invention is commercially available. For example it is obtained from the Sensory Effects Company (Product ID: Richmix 5025 IP(175755)), comprising a 52 % fat MCT oil powdered creamer made from palm-derived, palm kernel and/or coconut based fatty acids. According to the product description, maltodextrin and acacia gum, silicon dioxide and sunflower lecithin are also comprised in said product. Said MCTs have a melting point significantly below 20 °C, wherein the ratio of the MCT C6:C8:C10:C12 is approximately 1:20:10:1. In other words, the content of C6 and C12 in the MCTs used in the present invention is negligible. To this end, it is reiterated that any commercially available MCTs would be suitable to be used in the present invention, as long as the commercially available products meet the criteria and being sold as medium-chain triglycerides oil.
  • the use of a medium-chain triglyceride oil having a melting point below 20 °C such that the oil is liquid at room temperature also provides advantages to the manufacture of the homogenised tobacco material.
  • MCT oil exists naturally as a liquid at the room temperature, compared to other lipids such as wax, MCT oil does not required to be heated and melted.
  • the homogenised tobacco material which derived usually from a pulp does not need to be heated in order to retain the oil in liquid form. The manufacturing process can therefore be carried out without the need for external heating. This not only simplifies the manufacturing process but it also avoid the loss of volatile compounds from the tobacco-containing material during the external heating process.
  • the use of MCTs in the homogenised tobacco materials also solves the stickiness problem as typically found aerosol-generating article where lipids are being used in the manufacturing process.
  • the stickiness characteristic of lipid prevents volatile compounds to be released efficiently compared to MCTs.
  • the inventors of the present invention have found out from the test results that when the ratios of MCT to tobacco material on a dry basis are between 1 :3 and 1 :5, MCT works best in extracting volatile compounds from the tobacco-containing material. It has been found out that in those samples, not only the side tastes and off odour which typically exist in lipid-containing samples (e.g. wax) is no longer noticeable, it also gives the strongest tobacco aroma and flavours to the consumers, as well as the highest nicotine delivery.
  • the diffusivity of volatile compounds, such as aerosol formers and nicotine is greater in a liquid phase than in a solid phase.
  • the liquid medium- chain triglyceride will therefore act to facilitate the transfer of volatile compounds within the particulate tobacco material to its surface.
  • the transfer of these volatile compounds from the granulated tobacco material to an aerosol may be enhanced in comparison with a homogenised tobacco material that does not contain the liquid medium-chain triglyceride oil within the specific claimed ratios.
  • the inventors found out that when the ratios of MCT to tobacco material on a dry basis is outside of the claimed ranges of 1:3 and 1:5, the samples are immediately recognisable as less preferred choices. This is especially obvious when the samples contain a ratio of 1:10 or less of MCT to tobacco material on a dry basis, where these less preferred samples can be recognised immediately. It is therefore concluded that a certain minimum threshold of percentage of MCT to tobacco materials are needed in order to have the volatile compounds to be optimally extracted and be released as aerosol, as it allows for the formation of a good mixture of open pored foam and closed cell foam.
  • the medium chain triglyceride oil is preferably evenly distributed throughout the tobacco-containing material, which means that at room temperature there are no separately distinguishable regions of oil and plant material. Rather, the oil and particles are fully homogenised or granulated.
  • a homogenised tobacco material having a medium-chain triglyceride oil incorporated into it may allow equivalent nicotine or aerosol yields at a lower heating temperature compared to the use of a homogenised tobacco material without a medium chain triglyceride oil as defined.
  • a particulated tobacco-containing material with a medium-chain triglyceride at a certain ratio as defined herein may provide a higher nicotine or aerosol yield at a lower heating temperature than is provided by the same material at a higher heating temperature.
  • a lower heating temperature may provide a number of benefits when the composition of the invention, as it is meant for, is used in aerosol-generating devices such as heat-not-burn for instance.
  • a lower temperature of operation may allow for longer periods of use of the aerosol-generating device without the need to recharge a battery.
  • a lower temperature of operation may allow for use of a smaller battery.
  • a lower temperature of operation may reduce the liberation of undesirable aerosol constituents from the homogenised tobacco material. Examples 1
