To meet this market demand, e-cigarettes, as a new type of tobacco product, have gradually emerged in the public eye. However, due to their relatively short time on the market, there is still significant room for improvement in the sensory experience during use.

[0003] Currently, most e-cigarette products on the market are fruit-flavored, with a wide variety of fruit flavors emerging. However, their vaping experience is still lacking, mainly in terms of short-lasting aroma and insufficient intensity and richness. Therefore, there is a need to develop an e-cigarette liquid that can enhance the richness of the aroma. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an electronic atomizing liquid for enhancing aroma richness, wherein the electronic atomizing liquid comprises the following components by weight percentage:

[0005] Baijiu ester aroma substances 1-5%,

[0006] Fruity essential oils 10-25%,

[0007] Nicotine 1-2%, and

[0008] Solvent 64-86%;

[0009] The method for preparing the ester aroma substances of baijiu includes: transporting baijiu to a pervaporation device, collecting the permeate, subjecting the permeate to solid-phase extraction, and then eluting it with a mixed solvent to obtain the ester aroma substances of baijiu.

[0010] More specifically, in the above technical solution, the nicotine is nicotine or the nicotine component of nicotine salts; the solvent includes at least one of ethanol, water, propylene glycol, glycerol, diethylene glycol, triethylene glycol, and triacetin.

[0011] More specifically, in the above technical solution, the liquor is a strong-aroma type of liquor.

[0012] More specifically, in the above technical solution, the fruit-flavored essential oil includes one or more of apple essential oil, peach essential oil, banana essential oil, pineapple essential oil, strawberry essential oil, citrus essential oil, lemon essential oil, and grape essential oil.

[0013] More specifically, in the above technical solution, the electronic atomizing liquid also includes the following components by weight percentage: 2-4% modifier.

[0014] More specifically, in the above technical solution, the modifier includes cooling agents and / or sweeteners.

[0015] More specifically, in the above technical solution, the cooling agent includes one or more of WS-23, WS-3, WS-5, WS-12, menthol, menthone, isomenthone, isomenthone, menthyl acetate, L-carvone, menthyl lactate, isomenthyl acetate, and menthyl isovalerate.

[0016] More specifically, in the above technical solution, the sweetener includes at least one of sucralose, steviol glycosides, neotame, acesulfame potassium, glycyrrhizin, sodium saccharin, cyclamate, and monk fruit sweetener.

[0017] More specifically, in the above technical solution, the mixed solvent includes dichloromethane and pentane.

[0018] This application also proposes a method for preparing an electronic atomizing liquid that enhances aroma richness. The preparation method includes: weighing each component of the electronic atomizing liquid described above according to the weight percentage, stirring at room temperature until dissolved and mixed, and placing it in a cool, dark place for 24 hours to ethanolate, thereby obtaining the electronic atomizing liquid.

[0019] Compared with the prior art, the embodiments of this application have the following beneficial effects:

[0020] After the extraction steps described in this application, pure ester aroma substances are obtained from baijiu (Chinese liquor). Adding these substances to the electronic atomizing liquid can effectively enhance the richness of the aroma, allowing it to exude a full fruity aroma during atomization, accompanied by a faint aroma of liquor. The aroma is long-lasting and rich in layers. Moreover, the raw materials used in this application are generally readily available, stable in nature, and the preparation method is simple to operate, safe, and has no toxic side effects, thus having broad application prospects.

[0021] 98% of baijiu (Chinese white liquor) is an ethanol-water solution. When baijiu is directly added to the electronic atomizing fluid, substances with lower boiling points, such as ethanol and water, are preferentially released as the electronic atomizer heats up, resulting in lower vapor production. This also affects the effective heating zone for aerosol generation, thus reducing the release of aroma compounds, especially higher-boiling-point components, which are released later, impacting overall aerosol formation. The baijiu ester aroma compounds extracted from baijiu added in this application do not contain ethanol or water, effectively solving this problem. Detailed Implementation

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] 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 in this application's specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrase "some embodiments" appearing in various parts of this specification does not necessarily refer to the same embodiment, but rather means "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless otherwise specifically emphasized.

[0025] All materials and reagents used in this application can be purchased commercially.

[0026] An electronic atomizing fluid for enhancing aroma richness, said electronic atomizing fluid comprising the following components by weight percentage:

[0027] Baijiu ester aroma substances 1-5%,

[0028] Fruity essential oils 10-25%,

[0029] Nicotine 1-2%, and

[0030] Solvent 64-86%;

[0031] The method for preparing the ester aroma substances of baijiu includes: transporting baijiu to a pervaporation device, collecting the permeate, and then performing solid-phase extraction on the permeate, followed by elution with a mixed solvent to obtain the ester aroma substances of baijiu; preferably, baijiu is placed in a sealed container and transported to a pervaporation device, the permeate is collected into the container by a vacuum pump, and then the permeate is subjected to solid-phase extraction and eluted with a specific mixed solvent.

[0032] Baijiu, a type of Chinese liquor, has a long history and is one of the six major distilled spirits. Esters are a crucial component of baijiu, accounting for a significant proportion of its flavor compounds and playing a vital role in its taste and aroma, contributing a rich fruity flavor and body. The extraction process described in this application yields pure ester aroma compounds in baijiu. Adding these compounds to an electronic atomizing liquid effectively enhances the aroma's richness, allowing it to release a full fruity aroma with a subtle hint of liquor during atomization. The aroma is long-lasting and layered. Furthermore, the raw materials used in this application are readily available, stable, and the preparation method is simple, safe, and non-toxic, demonstrating broad application prospects.

[0033] It is understood that the liquor used in this application can be any brand of liquor on the market, or it can be traditional liquor brewed at home. This application does not impose any restrictions on it.

[0034] 98% of baijiu (Chinese white liquor) is an ethanol-water solution. When baijiu is directly added to the electronic atomizing fluid, substances with lower boiling points, such as ethanol and water, are preferentially released as the electronic atomizer heats up, resulting in lower vapor production. This also affects the effective heating zone for aerosol generation, thus reducing the release of aroma compounds, especially higher-boiling-point components, which are released later, impacting overall aerosol formation. The baijiu ester aroma compounds extracted from baijiu added in this application do not contain ethanol or water, effectively solving this problem.

[0035] This application also uses fruit essential oils as fragrance components, which can provide a fresh and rich fruity aroma. At the same time, the combination of fruit essential oils and ester aroma substances of white wine can make the overall aroma more harmonious and long-lasting.

[0036] The addition of nicotine can provide the aroma of tobacco, while also adjusting the taste and inhalation resistance of e-liquid, making the taste of e-liquid smoother and more comfortable.

[0037] Solvents can dissolve the various components, making the e-liquid more uniform and stable, while also ensuring the safety of the e-liquid.

[0038] In some embodiments, the nicotine is nicotine or the nicotine component of a nicotine salt; the solvent includes at least one of ethanol, water, propylene glycol, glycerol, diethylene glycol, triethylene glycol, and triacetin.

[0039] Nicotine salts are salts composed of nicotine and acids. Although called salts, they are not actually salts, but rather crystals formed by the reaction of free nicotine base with organic salts. Among commercially available nicotine salt samples, lactic acid, benzoic acid, and levulinic acid are the most common acids used in their manufacture, with benzoic acid being the most frequently used.

[0040] Organic nicotine salts are neutral because benzoic acid can lower the pH of nicotine, thereby reducing the alkalinity during smoking, which reduces the throat hit and provides a smoother experience, allowing users to inhale more nicotine. Therefore, using nicotine salts increases the level and rate at which nicotine is delivered to the user.

[0041] In some embodiments, the baijiu is a strong-aroma baijiu, which has a rich ester and koji aroma, and these aromas can add a unique taste and fragrance to the electronic atomizing liquid.

[0042] In some embodiments, the fruit-flavored essential oils include one or more of apple essential oil, peach essential oil, banana essential oil, pineapple essential oil, strawberry essential oil, citrus essential oil, lemon essential oil, and grape essential oil.

[0043] These fruit-flavored essential oils have a fresh and rich fruity aroma, which can add a variety of fragrances to e-liquids; and different fruit-flavored essential oils have different flavors and aromas, providing a variety of choices for e-liquids to meet the needs of different consumers.

[0044] In some embodiments, the electronic atomizing fluid further comprises, by weight percentage, 2-4% of the following components: a modifier. In some embodiments, the modifier comprises a cooling agent and / or a sweetener.

[0045] Cooling agents and sweeteners can enhance the taste of e-liquids, adjust their flavor, make inhalation more comfortable and pleasant, and make the aroma more harmonious and rich.

[0046] In some embodiments, the cooling agent includes one or more of WS-23, WS-3, WS-5, WS-12, menthol, menthone, isomenthone, isomenthone, menthyl acetate, L-carvone, menthyl lactate, isomenthyl acetate, and menthyl isovalerate.

[0047] These cooling agents can provide a cool taste to e-liquids, making inhalation more comfortable and pleasant. For example, WS-23 has the characteristics of being refreshing, long-lasting, fresh, without irritating spiciness or bitterness, and requires a low dosage to prolong the cool and refreshing feeling in the final application. The two new cooling agents, WS-5 and WS-12, have excellent cooling effects and tastes. WS-5 has a stronger cooling effect, while WS-12 has a longer-lasting cooling effect.

[0048] In some embodiments, the sweetener includes at least one selected from sucralose, steviol glycosides, neotame, acesulfame potassium, glycyrrhizin, sodium saccharin, cyclamate, and monk fruit sweetener.

[0049] Sweeteners such as sucralose, neotame, and acesulfame potassium are low-calorie or zero-calorie sweeteners, making them ideal for people who need to control their calorie intake. Those skilled in the art can add their specific types and dosages according to actual needs.

[0050] In some embodiments, the mixed solvent comprises dichloromethane and pentane, preferably, the mass ratio of dichloromethane to pentane during elution is 1:1, and the amount used is 10-30%.

[0051] This application also proposes a method for preparing an electronic atomizing liquid that enhances aroma richness. The preparation method includes: weighing each component of the electronic atomizing liquid described above according to the weight percentage, stirring at room temperature until dissolved and mixed, and placing it in a cool, dark place for 24 hours to ethanolate, thereby obtaining the electronic atomizing liquid.

[0052] The e-liquid prepared using the above method has advantages such as high quality, rich aroma, safety and reliability, harmonious and long-lasting flavor, efficient dissolution and sustainability, which can meet consumers' demand for high-quality e-liquid and improve the market competitiveness of the product.

[0053] Unless otherwise specified, the raw materials and equipment used in this application are all commonly used in the field; unless otherwise specified, the methods used in this invention are all conventional methods in the field.

[0054] Unless otherwise specified, the terms used in this specification have the same meaning as those commonly understood by those skilled in the art; however, in the event of any conflict, the definitions in this specification shall prevail.

[0055] To better illustrate the purpose, technical solution, and advantages of the present invention, the present invention will be further described below in conjunction with specific embodiments.

[0056] In the embodiments, the preparation methods of baijiu ester aroma substances are as follows: baijiu is transported to a pervaporation device, the permeate is collected, and the permeate is subjected to solid-phase extraction and then eluted with a mixed solvent of dichloromethane and pentane to obtain the baijiu ester aroma substances.

[0057] It is understandable that pervaporation devices, solid-phase extraction, and elution methods are all commonly used extraction methods in the chemical field, and their specific principles will not be elaborated here.

[0058] The components of the examples and comparative examples were stirred at room temperature until dissolved and mixed according to the formula, and then placed in a cool, dark place for 24 hours to ethanolate, thus obtaining the electronic atomizing liquid.

[0097] Table 1. Sucking Evaluation Criteria

[0098]

[0099] The e-liquids prepared in the examples and comparative examples were added to the same e-cigarettes in the same amount. After two rounds of vaping by 15 professional flavor tasters, each indicator was scored according to the evaluation criteria in Table 1 above. The average score of the two rounds was taken as the final evaluation result, as shown in Table 2 below:

[0100] Table 2. Suction Evaluation Results

[0102] As shown in Table 2 above, the e-liquid prepared using the formulation in the examples exhibits a rich and intense characteristic aroma, high overall fidelity, harmonious and consistent flavor, and a pleasant and long-lasting aftertaste, resulting in an excellent sensory experience during inhalation. Compared with the examples, the e-liquids prepared using the formulations in Comparative Examples 1-6 scored lower in terms of aroma, aftertaste, fidelity, harmony, and stability. This indicates that the addition of esters extracted from baijiu to the e-liquid significantly enhances the intensity and richness of the aroma. Furthermore, as the weight percentage of esters increases, the perceived richness of the aroma also intensifies, resulting in a full-bodied fruity aroma with a subtle hint of baijiu during atomization, characterized by a long-lasting and complex fragrance.

[0103] According to Comparative Example 7, replacing the ester aroma substances of baijiu with baijiu that has not undergone the extraction process resulted in a decrease in the sensory properties of the prepared electronic atomizing liquid. The reason is that 98% of baijiu is an ethanol-water solution. When baijiu is directly added to the electronic atomizing liquid, substances with lower boiling points, such as ethanol and water, are preferentially released as the electronic atomizer heats up, resulting in a lower amount of smoke. This also affects the effective heating area for generating aerosols to some extent, thus reducing the release of aroma substances, especially those with higher boiling points, which are released later and affect the overall formation of aerosols.

[0104] According to Comparative Example 8, no fruit flavoring oil was added. When the fruit flavoring oil was replaced with baijiu ester aroma substances, cooling agents, sweeteners and solvents, the sensory performance of the resulting electronic atomizing liquid decreased. The reason is that after removing the fruit flavoring oil, the baijiu ester aroma substances could not interact with the fruit flavoring oil to release a full fruit aroma, accompanied by a faint wine aroma. Therefore, all its sensory performances decreased.

[0105] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0106] The embodiments described above are merely illustrative of several implementations of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
