Description

Compositions for preparing aerosol generation matrices and aerosol generation matrices

[0001] Cross-reference to related applications

[0002] This disclosure is based on and claims priority to Chinese Patent Application No. 202411844779.5, filed on December 13, 2024, entitled “Composition for preparing aerosol generating matrix and aerosol generating matrix”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of tobacco technology, and in particular to a composition for preparing an aerosol generating matrix and the aerosol generating matrix. Background Technology

[0004] Aerosol generating matrix can form aerosols by ignition or by heating without combustion. In the heated-without-combustion type, the aerosol generating matrix is ​​heated by an external heat source to a temperature just sufficient to release aerosols without combustion. Alternatively, by loading a smoke-generating agent, the aerosol generating matrix is ​​heated during use to release the smoke-generating agent and form aerosols.

[0005] Using heated but non-combustible aerosol generating matrix to achieve low-harm tobacco products with reduced tar and harm is gradually becoming an industry trend. However, the aerosol generating matrix after tar reduction and harm reduction has quality defects such as weaker tobacco flavor, reduced aroma, and changes in style, resulting in a worse smoking experience.

[0006] Therefore, there is a need for an improved aerosol generation matrix that can solve or mitigate at least one of the problems existing in the prior art. Summary of the Invention

[0007] In view of this, the object of this disclosure is to provide a composition for preparing an aerosol generating matrix and the aerosol generating matrix itself. The aerosol generating matrix prepared using this composition has improved aroma component release rate and aerosol capture capacity.

[0008] The first aspect of this disclosure provides a composition for preparing an aerosol generating matrix, the composition comprising: a plant component; a smoke-generating component; a binder component; a flavoring component; and a sugar, the sugar being selected from one or more monosaccharides or oligosaccharides, wherein the enthalpy of melting of the sugar is greater than or equal to 200 J / g, and the melting peak temperature is 140℃-225℃.

[0009] In some embodiments, the sugar is selected from one or more of arabinose, lactose, glucose, and xylose.

[0010] In some embodiments, the sugar content is 0.1%-5% based on the total mass of the composition.

[0011] In some embodiments, the flavoring component is selected from one or more of tobacco extract, flavor plant extract, extract, essential oil, absolute oil, megastigmatrienone, neophytadiene, geraniol, nerol, menthol, and raspberry ketone.

[0012] In some embodiments, the content of the flavoring component is 0.1%-5% based on the total mass of the composition.

[0013] In some embodiments, the plant component is selected from one or more of tobacco raw materials, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants.

[0014] In some embodiments, the content of plant components is 65%-85% based on the total mass of the composition.

[0015] In some embodiments, the smoke-generating agent component is selected from one or more of the following: monohydric alcohol; dihydric alcohol; polyhydric alcohol; monocarboxylic acid, dicarboxylic acid, or esters formed from polycarboxylic acid and fatty alcohol.

[0016] In some embodiments, the smoke-generating agent component is selected from one or more of propylene glycol, glycerol, 1,3-butanediol, tetraethylene glycol, triacetin, triethyl citrate, a mixture of diacetin, methyl benzoate, and triglyceride.

[0017] In some embodiments, the content of the smoke-generating component is 2%-20% based on the total mass of the composition.

[0018] In some embodiments, the adhesive component is selected from one or more of tamarind polysaccharide, guar gum, and modified cellulose, wherein the modified cellulose is selected from one or more of sodium carboxymethyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, and hydroxypropyl cellulose.

[0019] In some embodiments, the content of the adhesive component is 0.5%-10% based on the total mass of the composition.

[0020] In some embodiments, the aerosol generating matrix is ​​a heat-non-combustible aerosol generating matrix.

[0021] A second aspect of this disclosure also provides an aerosol generating matrix, wherein the aerosol generating matrix is ​​prepared using the composition described in the first aspect of this disclosure.

[0022] The addition of sugar to the composition disclosed herein, as a material to stimulate the release of flavor components, can enhance the smoke concentration, strength, and aroma of the prepared aerosol generating matrix, thereby achieving a stronger sense of satisfaction and comfort. The addition of small-molecule sugars with the aforementioned enthalpy and melting peak temperature to the composition of this disclosure allows the prepared aerosol generating matrix to absorb more heat when heated to the same temperature. This facilitates the stimulation of flavor components in the aerosol generating matrix, ensuring that the flavor components are fully stimulated and released during heating, thus increasing the release amount of flavor components and the aerosol capture amount. Furthermore, the addition of sugars to the composition used to prepare the aerosol generating matrix allows for Maillard reactions with plant components during heating, resulting in substances that further enhance the aroma richness and aftertaste of the prepared aerosol generating matrix, improving the user's vaping experience. Detailed Implementation

[0023] The technical solutions of this disclosure will be clearly and completely described below with reference to the embodiments thereof. It should be understood that the described embodiments are only a part of the embodiments of this disclosure, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0024] Throughout this specification, unless otherwise specified, the terminology used herein should be understood as having the meaning commonly used in the art. Therefore, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. In the event of any conflict, this specification shall prevail.

[0025] It should be noted that, in the embodiments of this disclosure, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a method or apparatus that includes a list of elements includes not only the elements expressly described, but also other elements not expressly listed, or elements inherent to implementing the method or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other related elements in the method or apparatus that includes that element.

[0026] It should be noted that the terms "first," "second," and "third" used in the embodiments of this disclosure are merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted. It should be understood that the objects distinguished by "first," "second," and "third" can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those described herein.

[0027] To enrich the flavor of the aerosol generating matrix, various flavoring components are typically added. However, in heat-not-combustible aerosol generating matrices, due to the lower heating temperature, these flavoring components cannot fully exert their functions. Therefore, the aerosol generating matrix may experience problems such as a weaker tobacco flavor, diminished aroma, and altered style, resulting in a poorer vaping experience.

[0028] In view of this, the present disclosure provides a composition for preparing an aerosol generating matrix, the composition comprising: a plant component; a smoke-generating component; a binder component; a flavoring component; and a sugar, wherein the sugar is selected from one or more monosaccharides or oligosaccharides, wherein the enthalpy of melting of the sugar is greater than or equal to 200 J / g, and the melting peak temperature is 140℃-225℃.

[0029] In this disclosure, the plant component is the core source of aroma in the aerosol-generating matrix. Endogenous substances in the plant component, such as nicotine, enter the bloodstream and promote the production of dopamine by the pituitary gland, thereby achieving physiological satisfaction. The smoke-generating component produces smoke upon heating, thereby increasing the aerosol capture capacity of the prepared aerosol-generating matrix. The binder component achieves close contact with the interfaces of the various component materials in the composition through wetting, generating intermolecular attraction, thus binding the powders, liquids, etc., of the component materials. The fragrance component provides the aerosol-generating matrix with characteristic aromas, such as hay, roasted sweetness, or solid or liquid forms of nicotine.

[0030] In this disclosure, the composition used to prepare the aerosol generating matrix includes sugars selected from monosaccharides or oligosaccharides, wherein the enthalpy of melting of the sugar is greater than or equal to 200 J / g, and the melting peak temperature is 140℃-225℃. Sugars, as materials for activating the release of flavor components in the prepared aerosol generating matrix, can enhance the smoke concentration, strength, and aroma of the aerosol generating matrix, thereby achieving a stronger sense of satisfaction and comfort. During the heating process, the release rate of flavor components and the amount of aerosol captured in the aerosol generating matrix have a significant impact on the inhalation experience. Using small-molecule sugars with the aforementioned enthalpy and melting peak temperature allows the aerosol generating matrix to absorb more heat when heated to the same temperature, thereby increasing the internal energy of the aerosol generating matrix. This is beneficial for activating the flavor components in the aerosol generating matrix, ensuring that the flavor components are fully activated and released during heating, thus increasing the release amount of flavor components and the amount of aerosol captured. In addition, sugars are added to the composition used to prepare the aerosol generating matrix. During heating, they undergo a Maillard reaction with the plant components. The resulting substances further enhance the aroma richness and aftertaste of the aerosol generating matrix, thus improving the user's inhalation experience.

[0031] In this disclosure, "monosaccharide" refers to a sugar molecule that cannot be further hydrolyzed into smaller molecules. Based on the number of carbon atoms, sugars can be classified into trioses (trioses), tetraoses (tetraoses), pentoses (pentoses), hexoses (hexoses), etc. Exemplary monosaccharides include, but are not limited to, erythrose, threose, arabinose, ribose, xylose, lyseose, glucose, mannose, fructose, galactose, and hexoses.

[0032] In this disclosure, "oligosaccharide" is also known as "low-glycosyl sugar" and refers to a compound composed of 2 to 10 glycosidic bonds. Exemplary oligosaccharides include, but are not limited to, lactose, maltose, sucrose, fructooligosaccharides, and trehalose.

[0033] In this disclosure, "enthalpy of fusion" refers to the amount of heat absorbed by a unit mass of material when it melts from a solid to a liquid state. The higher the enthalpy of fusion, the more heat the material absorbs when it changes from a solid to a liquid state.

[0034] In this disclosure, "melting peak temperature" refers to the temperature at which a substance reaches its highest melting temperature during the heating process.

[0035] For example, the enthalpy of melting of sugar can be greater than or equal to 200 J / g, greater than or equal to 205 J / g, greater than or equal to 210 J / g, greater than or equal to 220 J / g, greater than or equal to 230 J / g, greater than or equal to 260 J / g, greater than or equal to 280 J / g, greater than or equal to 300 J / g, greater than or equal to 325 J / g, or greater than or equal to 345 J / g. In some embodiments, the enthalpy of melting of sugar is 200-350 J / g. For example, the peak melting temperature of sugar can be 140°C, 145°C, 150°C, 160°C, 170°C, 180°C, 185°C, 190°C, 200°C, 220°C, 225°C, or a value between any two of these values. In some embodiments, the peak melting temperature of sugar is 143°C-223°C.

[0036] "Fragrance component release rate" is quantitatively calculated as the ratio of fragrance component content before and after aerosol generation matrix aspiration. Fragrance component release rate (%) = [(Fragrance component content before aspiration - Fragrance component content after aspiration) / Fragrance component content before aspiration] × 100%. The content of the fragrance component can be measured using methods known to those skilled in the art, such as gas chromatography-mass spectrometry. In this disclosure, the terms "fragrance component release rate" and "fragrance release rate" are used interchangeably.

[0037] The "aerosol capture amount" can be measured using the following exemplary method. Specifically, smoke is drawn using a fully automatic rotary heated non-combustible cigarette smoking machine (Puffman-X500E-L). A trap is used to capture the smoke, and the mass of the trap before and after smoking is measured. The aerosol capture amount is calculated using the following formula: Aerosol capture amount = (Mass of the trap after smoking - Mass of the trap before smoking) / n, where n is the number of aerosol-generating substrates drawn. The trap can be, for example, a Whatman 44mm Cambridge filter (F319-04).

[0038] In some embodiments, the sugar is selected from one or more of arabinose, lactose, glucose, and xylose. These small-molecule sugars have a crystalline structure and transform from a crystalline to an amorphous structure during heating. Their large enthalpy of melting means that a large amount of heat needs to be absorbed during this transformation, thereby giving the aerosol-generating matrix higher internal energy after heating, which is more conducive to the activation of flavor components and thus improves the release rate of flavor components from the aerosol-generating matrix. Optionally, the sugar is selected from one or more of arabinose, lactose, and glucose. In a preferred embodiment, the sugar is arabinose.

[0039] In some embodiments, the sugar content is 0.1%-5% based on the total mass of the composition. Maintaining the sugar content within this range is beneficial for improving the aroma release, aroma richness, and aerosol capture of the aerosol-generating matrix. Exemplarily, the sugar content, based on the total mass of the aerosol-generating matrix, can be 0.1%, 0.5%, 1%, 1.5%, 2%, 3%, 4%, 5%, or a value between any two of these values. In some preferred embodiments, the sugar content is 1%-3% based on the total mass of the aerosol-generating matrix.

[0040] In some embodiments, the flavoring component is selected from one or more of tobacco extracts, aromatic plant extracts, extracts, essential oils, absolutes, megastigmatrienone, neophytadiene, geraniol, nerol, menthol, and raspberry ketone. Optionally, the flavoring component is selected from one or more of megastigmatrienone, neophytadiene, geraniol, nerol, menthol, and raspberry ketone. Optionally, the flavoring component is selected from one or more of menthol and raspberry ketone. Optionally, the flavoring component is a mixture of menthol and raspberry ketone, wherein the mass ratio of menthol to raspberry ketone is 3:1. Using the above flavoring components can provide a richer aroma profile to the aerosol-generating matrix, thereby enhancing the inhalation experience.

[0041] In some embodiments, the content of the fragrance component is 0.1%-5.0% based on the total mass of the composition. By placing the fragrance component within the above range, it is beneficial to enhance the aroma richness of the aerosol-generating matrix, thereby improving the inhalation experience. Exemplarily, the content of the fragrance component, based on the total mass of the aerosol-generating matrix, can be 0.1%, 0.5%, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, 3.5%, 4.0%, 4.5%, 5.0%, or a value between any two of these values. In some embodiments, the content of the fragrance component, based on the total mass of the composition, is 1.5%-5.0%, optionally 1.5%-3.0%.

[0042] In some embodiments, the plant component is selected from one or more of tobacco leaf raw materials, tobacco leaf fragments, tobacco stems, tobacco dust, and aromatic plants. In some embodiments, the aromatic plants are selected from one or more of tea leaves, thyme, osmanthus, lemon, lavender, and benzoin. Optionally, the plant component is selected from tobacco leaf raw materials. There are no particular limitations on the form of the above-mentioned plant component, and forms conventional in the art can be used. For example, the above-mentioned plant component can be in powder form after being crushed.

[0043] In some embodiments, the plant component content is 65%-85% by weight of the total composition. By keeping the plant component content within the above range, a core aroma is provided to the aerosol-generating matrix, offering the user a better inhalation experience. Exemplarily, the plant component content, by weight of the total composition, can be 65%, 70%, 75%, 80%, 85%, or a value between any two of these values. In some embodiments, the plant component content is 70%-80% by weight of the total composition, optionally 75%.

[0044] In some embodiments, the smoke-generating component is selected from one or more of the following: monohydric alcohols; dihydric alcohols; polyhydric alcohols; esters formed from monocarboxylic acids, dicarboxylic acids, or polycarboxylic acids and fatty alcohols. Using the above-mentioned smoke-generating components is beneficial for providing a large amount of smoke, thereby increasing the aerosol capture rate generated by the aerosol-generating matrix. In some embodiments, the smoke-generating component is selected from one or more of propylene glycol, glycerol, 1,3-butanediol, tetraethylene glycol, triacetin, triethyl citrate, a mixture of diacetin, methyl benzoate, and triglyceride. Optionally, the smoke-generating component is selected from one or more of propylene glycol, glycerol, 1,3-butanediol, and tetraethylene glycol. Optionally, the smoke-generating component is selected from one or more of propylene glycol and glycerol.

[0045] In some embodiments, the content of the smoke-generating component, based on the total mass of the composition, is 2%-20%. Maintaining the content of the smoke-generating component within this range is beneficial for increasing the aerosol capture rate generated by the aerosol-generating matrix. Exemplarily, the content of the smoke-generating component, based on the total mass of the composition, can be 2%, 5%, 8%, 10%, 15%, 18%, 20%, or a value between any two of these values. In some embodiments, the content of the smoke-generating component, based on the total mass of the composition, can be 15%-20%.

[0046] In some embodiments, the binder is selected from one or more of tamarind polysaccharide, guar gum, and modified cellulose, wherein the modified cellulose is selected from one or more of sodium carboxymethyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, and hydroxypropyl cellulose. The above-mentioned binder achieves close contact with the interfaces of the various component materials in the composition used to prepare the aerosol generating matrix by wetting, generating intermolecular attraction, thereby serving to bind the powders, liquids, etc., of the component materials. Optionally, the binder is selected from one or more of guar gum, sodium carboxymethyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, and hydroxypropyl cellulose.

[0047] In some embodiments, the content of the adhesive component is 0.5%-10% by weight of the total composition. By keeping the content of the adhesive component within this range, it is beneficial to tightly bond the raw material components in the composition, thereby facilitating the molding of the individual components in the composition using a one-piece molding process. Exemplarily, the content of the adhesive component by weight of the total composition can be 0.5%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, or a value between any two of these values. In some embodiments, the content of the adhesive component is 1%-5% by weight of the total composition.

[0048] In some embodiments, the composition for preparing the aerosol generating matrix, based on the total mass of the composition, comprises: 65%-85% plant components; 2%-20% smoke-generating agent components; 0.5%-10% binder components; 0.1%-5% fragrance components; and 0.1%-5% sugar. Preferably, the composition for preparing the aerosol generating matrix, based on the total mass of the composition, comprises 70%-80% plant components; 15%-18% smoke-generating agent components; 2%-5% binder components; 1%-3% fragrance components; and 1%-3% sugar.

[0049] In some embodiments, the aerosol generating matrix is ​​a heat-non-combustible aerosol generating matrix.

[0050] In some embodiments, the composition is prepared as an aerosol generating matrix using a one-piece molding process. This one-piece molding process overcomes the problems of lint shedding and difficulty in cleaning that occur with granular, tobacco-based, and flake-based aerosol generating matrices during inhalation. This improves the user experience.

[0051] In this disclosure, "integrated molding process" includes injection molding, compression molding, or extrusion molding. Extrusion molding refers to a processing method in which a raw material composition is added to an extruder, and the material is simultaneously heated and plasticized by the action between the extruder barrel and screw, and continuously pushed forward by the screw through the die head to form products or semi-finished products of various cross-sections. The aerosol matrix formed by extrusion molding is in the form of strips. Because the aerosol generating matrix has an integrated structure, it remains a unified medium after being heated and absorbed or after heating ceases, preventing disintegration and shedding. This helps reduce problems such as fiber shedding and difficulty in cleaning the aerosol generating matrix.

[0052] This disclosure also provides an aerosol generating matrix prepared using the above-described composition. In some embodiments, the aerosol generating matrix is ​​prepared using the composition described above via a one-piece molding process.

[0053] This disclosure also provides an aerosol generating article. The aerosol generating article includes the aerosol generating matrix, functional segment, and encapsulation layer described above. The functional segment is disposed at one end of the aerosol generating matrix along its length, and the functional segment includes a cooling segment for lowering the aerosol temperature. The encapsulation layer covers the circumferential exterior of the functional segment and the aerosol generating matrix.

[0054] Aerosol generating products are intended for use with aerosol generating devices equipped with heating components. Specifically, the heating component heats and atomizes the aerosol generating matrix to produce aerosols. The user then draws in the cooled aerosol through a cooling section within the functional segment. The aerosol generated by the aerosol generating matrix is ​​transported to the cooling section under suction negative pressure. The cooling section is used to cool the aerosol. This cooling section helps to reduce the "burning" sensation experienced by the user when drawing in the aerosol.

[0055] The cooling materials used in the cooling section include, but are not limited to, one or more of the following: polyethylene (PE), polylactic acid (PLA), polybutylene adipate terephthalate (PBAT), polypropylene (PP), cellulose acetate, and propylene fiber.

[0056] The coating layer can protect the aerosol-generating matrix. The coating layer includes, but is not limited to, one or more of the following materials: fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, polyethylene (PE), polybutylene terephthalate (PBAT).

[0057] It should be noted that the aerosol generating matrix included in the aerosol generating article is used to generate aerosols, while the functional section does not generate aerosols.

[0058] In some implementations, the functional section also includes a filtration section. The filtration section is used to filter aerosols.

[0059] The filter materials used in the filtration section include, but are not limited to, one or more of the following: polyethylene (PE), polylactic acid (PLA), polybutylene adipate terephthalate (PBAT), polypropylene (PP), cellulose acetate, and cellulose acrylic.

[0060] The cooling section and the filtration section can be made of the same material or different materials.

[0061] This disclosure also provides an aerosol generation system. The aerosol generation system includes an aerosol generation apparatus having a heating component and the aerosol generation article described above. Specifically, the heating component heats and atomizes the aerosol generation matrix to generate aerosols.

[0062] This disclosure also provides the use of sugars in aerosol generating matrices for stimulating aroma in the aerosol generating matrix, wherein the sugars are selected from one or more monosaccharides or oligosaccharides. Optionally, the aerosol generating matrix is ​​a heat-non-combustible aerosol generating matrix.

[0063] The present disclosure will now be described in further detail with reference to specific embodiments. These descriptions are merely illustrative and not intended to limit the scope of the disclosure.

[0064] Example

[0065] All non-tobacco raw materials used in the following examples are commercially available.

[0066] In the following examples, a screw extruder is used to extrude the raw material composition to obtain an aerosol generation matrix.

[0067] Example 1

[0068] 75 parts by weight of tobacco plant components, 18 parts by weight of the smoke-generating agent glycerol, 3 parts by weight of the flavoring component, 3 parts by weight of the binder sodium carboxymethyl cellulose (CMC-Na), and 1 part by weight of arabinose were weighed and mixed evenly to obtain a composition for preparing an aerosol generating matrix. The flavoring component was a compound flavoring of menthol and raspberry ketone in a mass ratio of 3:1. The obtained composition was then extruded to prepare an aerosol generating matrix.

[0069] Examples 2-4

[0070] According to the formulation shown in Table 1 below, weigh each raw material in the composition and mix them evenly. Prepare the aerosol generating matrix by the same method as in Example 1.

[0071] Comparative Examples 1-2

[0072] According to the formulation shown in Table 1 below, weigh each raw material in the composition and mix them evenly. Prepare the aerosol generating matrix of the obtained composition in the same manner as in Example 1. Comparative Example 1 does not include sugar, and the enthalpy of melting of fructose included in Comparative Example 2 is less than 200 J / g.

[0073] Table 1: Composition formulations for preparing aerosol generation matrices

[0074] In the table, " / " indicates that it has not been added.

[0075] The melting enthalpy ΔH and melting peak temperature Tm of the sugars used in the above examples and comparative examples were measured using the following methods, and the test results are shown in Table 2.

[0076] Methods for measuring the enthalpy of melting ΔH and the peak melting temperature Tm:

[0077] The MELLTER TGA / DSC3+ test was used, with the temperature profile set as follows: heating from 30℃ to 320℃ at a rate of 20℃ / min and an air flow rate of 50mL / min. After the test, the test data were imported into the MELLTER-STARe software for data analysis, and the melting enthalpy ΔH and melting peak temperature Tm of the tested material were calculated.

[0078] Table 2: Enthalpy of melting (ΔH) and peak melting temperature (Tm) of sugars

[0079] The performance of the aerosol generating matrices of the above embodiments and comparative examples was tested according to the following test methods.

[0080] 1. Sensory evaluation method: Sensory evaluation shall be conducted in accordance with GB5606.4-2005.

[0081] 2. Test on the aerosol capture capacity of the aerosol generating matrix released during suction.

[0082] Aerosol capture capacity test method: Smoke was drawn using a fully automatic rotary heated non-combustible cigarette smoking machine (Puffman-X500E-L). The following parameters were set: suction volume of 55ml, suction time of 2s, suction interval of 28s, number of puffs of 10, and a bell-shaped suction curve. A Whatman 44mm Cambridge filter (F319-04) was used to capture the smoke. The mass of the filter before smoking was measured using a 0.01% balance. After smoking 4 cigarettes, the filter mass was measured again. The aerosol capture capacity of the aerosol-generating matrix per cigarette = (mass of the filter after smoking - mass of the filter before smoking) / 4.

[0083] 3. Test of fragrance component content in the aerosol-generating matrix before and after aspiration.

[0084] Method for testing the content of flavoring components: Smoke was drawn using a fully automatic rotary heated non-combustible cigarette smoking machine (Puffman-X500E-L). The following parameters were set: draw volume of 55ml, draw time of 2s, draw interval of 28s, number of puffs of 10, and a bell-shaped draw curve. Flavoring components, such as menthol and raspberry ketone, were extracted from the aerosol-generating matrix before and after drawing, and then analyzed using an Agilent 8890GC 5977B MS gas chromatography-mass spectrometry system. The content of flavoring components in the aerosol-generating matrix was determined.

[0085] Fragrance component release rate (%) = [(Fragrance component content before aspiration - Fragrance component content after aspiration) / Fragrance component content before aspiration] × 100%

[0086] Table 3: Sensory evaluation of aerosol-generating matrices of Examples 1-4 and Comparative Examples 1-2

[0087] As shown in Table 3, the addition of arabinose, glucose, lactose, and xylose in Examples 1 to 4, respectively, is beneficial for enhancing the smoky aroma, mainly manifested in improvements in at least one aspect of aroma, aftertaste, and harmony compared to Comparative Examples 1 and 2. Among these, arabinose in Example 1 showed the best smoky aroma enhancement effect, primarily due to its higher enthalpy of melting. In contrast, Comparative Example 1, which did not contain any small-molecule sugars, and Comparative Example 2, which contained fructose with a lower enthalpy of melting, did not significantly enhance the smoky aroma.

[0088] Table 4: Test results of aerosol capture amount and fragrance component content of aerosol generating matrices in Examples 1-4 and Comparative Examples 1-2

[0089] As shown in Table 4, the aerosol capture results indicate that, compared to Comparative Example 1, the addition of small-molecule sugars to the aerosol generating matrix in Examples 1-4 increases the aerosol capture rate, indicating a better aroma-enhancing effect. In contrast, the addition of fructose with a lower melting enthalpy in Comparative Example 2 resulted in a slight increase in aerosol capture compared to Comparative Example 1, but the effect was not significant. The flavor component content test results show that the addition of small-molecule sugars to the aerosol generating matrix in Examples 1-4 promotes the release of flavor components during inhalation, increasing the amount of flavor components migrating into the smoke.

[0090] Examples 5-9

[0091] According to the formulation shown in Table 5 below, weigh each raw material in the composition and mix them evenly. Prepare the aerosol generating matrix by the same method as in Example 1.

[0092] Comparative Example 3

[0093] According to the formulation shown in Table 5 below, weigh each raw material in the composition and mix them evenly. Prepare the aerosol generating matrix of the obtained composition in the same manner as in Example 1. The sugar content in Comparative Example 3 is greater than 5% by mass.

[0094] Table 5: Composition formulations for preparing aerosol generation matrices

[0095] The aerosol-generating matrices of Examples 5-9 and Comparative Example 3 were subjected to sensory evaluation, aerosol capture capacity testing, and fragrance component content testing according to the test methods described above. The sensory evaluation results are shown in Table 6, and the aerosol capture capacity testing and fragrance component content testing results are shown in Table 7.

[0096] Table 6: Sensory evaluation results of Examples 5-9 and Comparative Example 3

[0097] As shown in Table 6, the overall sensory score gradually increased as the amount of arabinose added increased from 0.1% to approximately 2%. As the amount of arabinose added increased to approximately 3%–5%, the overall score decreased, but remained relatively high, exceeding that of Comparative Examples 1 and 2. When the amount of arabinose added was too high, for example, to approximately 7% (Comparative Example 3), the overall sensory evaluation result of the aerosol-generating matrix decreased.

[0098] Table 7: Results of aerosol capture and fragrance component content tests in Examples 5-9 and Comparative Example 3

[0099] As shown in Table 7, the release rate of flavor components increased from 92.4% to 94.4% when the amount of arabinose added increased from 0.1% to approximately 2%.
