[0014] To more clearly illustrate the solution of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0015] Figure 1 This is a flowchart of a method for preparing a sweet flavoring substance provided in an embodiment of this application. Detailed Implementation

[0016] 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 application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0017] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] The rapid development of atomizer products has injected fresh blood into the tobacco market. Atomizers can satisfy consumers' smoking needs while avoiding the harm to the human body caused by tar produced by traditional cigarettes. The taste of the aerosol matrix is ​​significantly affected by sweeteners. Currently, most commercially available products use synthetic sweeteners (such as sucralose, acesulfame potassium, and aspartame). However, synthetic sweeteners may decompose and produce harmful substances when atomized at high temperatures. For example, sucralose may release potentially carcinogenic substances such as chloropropanol when heated to high temperatures (200-300℃). Furthermore, synthetic sweeteners may irritate the respiratory tract, while natural extracts are closer to food-grade safety standards, reducing the risk of long-term inhalation. Also, synthetic sweeteners (such as sodium saccharin and acesulfame potassium) are prone to producing a metallic or bitter taste at high concentrations, affecting the user experience.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0020] A sweet flavoring substance comprising: a natural sweetener, a flavoring agent, a modifier, and a first solvent.

[0021] The sweet flavor substance provided in this application has a high sweetness and pure sweetness without the use of synthetic sweeteners, preventing the generation of harmful substances during high-temperature atomization. At the same time, this application effectively ensures the pure taste of the sweet flavor substance by reasonably combining different kinds of natural sweet materials and supplementing them with flavoring materials to modify the sweetness and mask off-flavors, without any off-flavors or impurities, thus improving the taste and avoiding irritation to the respiratory tract.

[0022] In some embodiments, the regulator is selected from one or more of malic acid, citric acid, lactic acid, and tartaric acid. The regulator can lower the pH value of the aerosol matrix, making it closer to the acidic environment produced by traditional tobacco combustion. Appropriate acidity can make the throat hit smoother, reduce irritation, avoid throat irritation, and improve the throat hit and overall taste experience. Simultaneously, the regulator is a food-grade additive that provides a fresh, bright, and safe sour taste, simulating the flavor of real fruit, giving the aerosol a sweet and sour taste. The taste is more natural and vibrant for the user, reducing cloying sweetness and effectively balancing the sweetness in the aerosol matrix, avoiding the cloying feeling caused by excessive sweetness. By adjusting the acidity, the aerosol matrix can have a more refreshing taste, improving the overall flavor harmony. Working synergistically with the natural sweeteners and flavoring materials, it can enhance the perceived intensity of the overall flavor, making the aroma fuller and more three-dimensional. Furthermore, the regulator has a certain antioxidant effect, which can help stabilize the flavor components in the aerosol matrix and extend the product's shelf life.

[0023] In some embodiments, the natural sweetener is selected from one or more of the following: neomethyl hesperidin dihydrochalcone, steviol glycosides, ribobadiol A, ribobadiol M, glycyrrhizic acid, ammonium glycyrrhizate, dipotassium glycyrrhizate, mogroside, sorbitol, maltitol, erythritol, and D-allulose. The natural sweetener exhibits good thermal stability and a clear metabolic pathway, meaning it is excreted after intestinal decomposition and does not accumulate in the body, thus preventing impact on intestinal flora or metabolism. Furthermore, many regions have strict regulations on synthetic additives, while the natural sweetener used in this application is approved for use in the food and beverage industries, i.e., a food-grade additive, resulting in higher compliance in the aerosol matrix field and easier approval. Simultaneously, the natural sweetener has a pure sweetness and some possess natural plant flavors; for example, steviol glycosides have a slight licorice aroma, which enhances the layering of the aerosol matrix, reduces the "fake sweetness" of artificial flavors, meets the requirement of no artificial additives, satisfies the modern consumer preference for "clean label" products, and enhances product competitiveness. Furthermore, the natural sweeteners mentioned are sugar substitutes, possessing excellent properties such as being calorie-free, highly sweet, flavorful, non-nutritive, having a long shelf life, low calorie value, and high safety, making them suitable for those prone to obesity. Simultaneously, this application utilizes a rational combination of different types of natural sweeteners, supplemented with flavoring materials to modify the sweetness and mask off-flavors, effectively ensuring the purity of the sweet flavor substances' taste, eliminating any off-flavors or impurities, enhancing the overall taste, and avoiding respiratory irritation.

[0024] In some embodiments, the flavoring material is selected from one or more of daumarenone, ionone, raspberry ketone, γ-decyl lactone, phenethyl alcohol, phenylacetaldehyde, phenethyl acetate, benzyl formate, hexyl formate, ethyl acetate, benzyl acetate, butyl acetate, ethyl propionate, vanillin, and ethyl maltol. The flavoring material can produce a strong, highly recognizable aroma, effectively suppressing background off-flavors. Specifically, it modifies the natural sweetener, masks impurities and off-flavors from the natural sweetener, introduces sweetness, enhances the fruit flavor characteristics, increases the complexity and layering of the aroma, strengthens the overall flavor perception, and makes the aroma fuller and more three-dimensional, avoiding metallic or bitter tastes.

[0025] In some embodiments, the first solvent is selected from one or more of propylene glycol, glycerol, and water. The first solvent helps dissolve the natural sweeteners, flavorings, and modifiers, allowing the aerosol matrix to form an aerosol upon heating, thus improving the uniformity and stability of the aerosol matrix. Furthermore, the use of propylene glycol and glycerol is healthy and environmentally friendly.

[0026] Furthermore, cooling agents such as WS-3 and WS-23 can be added to stimulate cold receptors in the mouth and throat, bringing a cooling sensation and making the vaping experience more comfortable. At the same time, they can effectively reduce the irritation caused by nicotine, making the vaping experience smoother. Moreover, the synergistic effect of the cooling agents and the natural sweeteners further enhances the explosiveness of the natural sweeteners, making the aroma more pleasantly caramelized, with a natural sweetness and a strong caramelized flavor.

[0027] In some embodiments, the components of the sweet flavoring substance are allocated as follows by mass percentage: 1-20% natural sweetener, 0.1-2% flavoring agent, 0.1-10% modifier, and the balance being the first solvent.

[0028] An appropriate ratio enhances the sweetness and purity of the sweet flavor substances. The amount added can be adjusted according to actual needs. Flavoring materials are added to modify the sweetness and mask off-flavors, effectively ensuring the pure taste of the sweet flavor substances, without any off-flavors or impurities, improving the taste, avoiding respiratory irritation, and the appropriate ratio can also improve solubility and reduce carbon buildup.

[0029] It is understandable that natural sweeteners are selected from any value or any two values ​​within the range of 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, and 20%. Flavoring materials are selected from any value or any two values ​​within the range of 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1.0%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, and 2.0%. Modifiers are selected from any value or any two values ​​within the range of 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1.0%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, and 10%.

[0030] As attached Figure 1 As shown, based on the above-mentioned sweet flavor substances, this application embodiment also provides a method for preparing sweet flavor substances, which adopts the following technical solution: Includes the following steps: S100 provides natural sweeteners, flavorings, modifiers, and primary solvents; S200. Mix the regulator and the first solvent, and heat and stir to obtain a regulator solution; S300: Mix the natural sweetener, flavoring agent, first solvent and regulator solution, and heat and stir to obtain the sweet flavoring substance.

[0031] The sweet flavor substance provided in this application has a high sweetness and pure sweetness without the use of synthetic sweeteners, preventing the generation of harmful substances during high-temperature atomization. At the same time, this application effectively ensures the pure taste of the sweet flavor substance by reasonably combining different kinds of natural sweet materials and supplementing them with flavoring materials to modify the sweetness and mask off-flavors, without any off-flavors or impurities, thus improving the taste and avoiding irritation to the respiratory tract.

[0032] Furthermore, the modifier and natural sweetener described in this application are compounded using the first solvent. The high sweetness of the natural sweetener brings a powerful burst of sweetness, the flavoring material can mask the off-flavors of the synthetic sweetener, and the natural sweetener can adjust the comfort of the sweetness.

[0033] In some embodiments, the heating and stirring parameters are: stirring speed of 100-400 r / min, temperature of 30-70℃, and stirring time of 10-50 min. Appropriate heating and stirring parameters ensure thorough mixing of the components.

[0034] This can be understood as the range formed by any or two of the following stirring speeds: 100 r / min, 150 r / min, 200 r / min, 250 r / min, 300 r / min, 350 r / min, and 400 r / min. The temperature can be any or two of the following temperatures: 30℃, 35℃, 40℃, 45℃, 50℃, 55℃, 60℃, 65℃, and 70℃. The stirring time can be any or two of the following times: 10 min, 15 min, 20 min, 25 min, 30 min, 35 min, 40 min, 45 min, and 50 min.

[0035] In some embodiments, the regulator comprises malic acid and citric acid, and the step of mixing the regulator and a first solvent and heating and stirring to obtain a regulator solution includes the following steps: Malic acid and the first solvent are mixed and heated and stirred to obtain a malic acid solution; Citric acid and the first solvent are mixed and heated and stirred to obtain a citric acid solution.

[0036] The regulator is compounded with the first solvent, which is mainly water, to improve the solubility and dispersibility of the regulator. Then it is mixed with the natural sweetener and flavoring material to achieve a synergistic effect. The high sweetness of the natural sweetener brings a strong burst of sweetness, the flavoring material can mask the off-flavors of the synthetic sweetener, and the natural sweetener can adjust the comfort of the sweetness.

[0037] Furthermore, in some embodiments, the malic acid and citric acid are respectively compounded with water before use, and the ratio of malic acid to water is 1:1, and the ratio of citric acid to water is 1:1.

[0038] Based on the above-mentioned sweet flavor substances and their preparation methods, this application also provides an aerosol matrix, which adopts the following technical solution: The aerosol matrix includes: a second solvent, nicotine salt, flavoring, and the sweet flavoring substance or the sweet flavoring substance prepared by the method of preparing the sweet flavoring substance; The amount of the sweet flavoring substance added to the aerosol matrix is ​​0.1% to 1%.

[0039] The sweet flavor substance provided in this application has a high sweetness and pure sweetness without the use of synthetic sweeteners, preventing the generation of harmful substances during high-temperature atomization. At the same time, this application effectively ensures the pure taste of the sweet flavor substance by reasonably combining different kinds of natural sweet materials and supplementing them with flavoring materials to modify the sweetness and mask off-flavors, without any off-flavors or impurities, thus improving the taste and avoiding irritation to the respiratory tract.

[0040] It is understood that the amount of the sweet flavoring substance added to the aerosol matrix is ​​any one or any two of the following values: 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, and 1.0%.

[0041] In some embodiments, the aerosol matrix is ​​composed of the following components by mass percentage: 0.1-5% nicotine salt, 5-15% fragrance, and the remainder is a second solvent; The nicotine salt is selected from one or more of nicotine benzoate, nicotine salicylate, nicotine lactate, nicotine citrate, and nicotine tartrate; and / or, The fragrance is selected from one or more of the following: strawberry essence, mint essence, citrus essence, apple essence, and wintergreen essence; and / or, The second solvent is selected from one or more of propylene glycol and glycerol.

[0042] The nicotine salts improve the absorption efficiency of nicotine in the human body, enhance the taste and throat hit, allowing users to comfortably inhale higher concentrations of nicotine and providing a smoother vaping experience. Compared to free nicotine, the nicotine salts are more stable and less volatile, extending the shelf life of the aerosol matrix. The flavoring provides aroma to the atomizing liquid and is compounded using the second solvent. The high-intensity sweetness of the natural sweeteners delivers a powerful burst of sweetness, while the flavoring materials mask the off-flavors of synthetic sweeteners. The natural sweeteners adjust the comfort of the sweetness, and the appropriate proportions can improve solubility and reduce carbon buildup.

[0043] It is understandable that nicotine salts are selected from any value or any two values ​​within the range of 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1.0%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, 2.0%, 2.1%, 2.2%, 2.3%, 2.4%, 2.5%, 2.6%, 2.7%, 2.8%, 2.9%, 3.0%, 3.1%, 3.2%, 3.3%, 3.4%, 3.5%, 3.6%, 3.7%, 3.8%, 3.9%, 4.0%, 4.1%, 4.2%, 4.3%, 4.4%, 4.5%, 4.6%, 4.7%, 4.8%, 4.9%, and 5.0%.
