BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to more clearly illustrate the solution of the present application, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the drawings in the following description are some embodiments of the present application. For those of ordinary skill in the art, other drawings can be obtained according to these drawings without creative efforts.

[0033] Figure 1 It is a flowchart of a preparation method of a caramel flavor substance provided by an embodiment of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] 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 pertains; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0035] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0036] The rapid development of atomizer products has injected fresh blood into the tobacco market. While meeting consumers' needs for smoking, atomizers avoid the harm to the human body caused by tar in traditional cigarettes. In addition, the nicotine content in atomizers is controllable, and consumers can choose according to their own needs. The aerosol matrix is the key factor determining the taste of atomizers. To enrich the taste of e-liquid and improve the off-flavors of atomizers, the industry often adds characteristic flavors such as fruit flavors and flower flavors to e-liquid. Therefore, there is an urgent need to develop an aerosol matrix that has both a more authentic tobacco flavor and sweet and caramel aromas.

[0037] The description of caramel-sweet aroma is usually the fragrance of sugarcane accompanied by a strong caramel aroma. The aroma components mainly include aldehydes, alcohols, ketones, acids, pyrazines, furans, sulfur-containing compounds, etc. There are varying degrees of synergistic or inhibitory effects among these components. The traditional essence formula is mainly composed of some artificially synthesized monomer raw materials. Although the caramel essence produced using these raw materials has a certain caramel-sweet aroma, the use of synthetic raw materials affects the natural flavor of caramel in e-liquid. There is only a sweet feeling but no caramel feeling in the aroma, making the naturalness of the produced caramel-sweet not strong, the aroma not natural, and the characteristic sense of sweet aroma lacking, with poor market acceptance.

[0038] Caramel aroma is a common aroma in life. The caramel flavor can be formulated with monomer raw materials. For example, aroma raw materials such as methyl cyclopentenolone, maltol, ethyl maltol, and furanone all have the attribute of caramel-sweet. However, using monomer essence alone for formulation will also result in a lack of natural attributes, a strong chemical smell, and poor coordination. Therefore, the idea is to combine these two aroma substances to develop an essence with a caramel-sweet flavor.

[0039] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings.

[0040] A caramel-sweet flavor substance, by weight, the caramel-sweet flavor substance includes: 2-3 parts of concentrated sugarcane juice, 0.006-0.008 parts of glucose, 0.004-0.01 parts of glycine, 0.003-0.005 parts of alanine, 0.004-0.01 parts of phenylalanine, 0.004-0.01 parts of aspartic acid, and 1-1.5 parts of propylene glycol.

[0041] The caramel-sweet flavor substance of this application has both a natural sweet taste and a strong caramel taste. Through the cooperation of each component, the caramel-sweet flavor substance has a fresh, rich and natural caramel aroma. The aromas of each component are coordinated, and the caramel-sweet flavor is full, delicate, long-lasting, and solves the problem of single aroma in the prior art.

[0042] To solve the above technical problems, the embodiments of this application also provide a preparation method of a caramel-sweet flavor substance, adopting the following technical solutions:

[0043] A preparation method of a caramel-sweet flavor substance includes the following steps:

[0044] S100. Place the raw materials in a reaction flask and perform ultrasonic treatment to obtain a primary solution;

[0045] S200. Adjust the pH value of the primary solution to 8-10;

[0046] S300. Seal the reaction flask and perform Maillard reaction by heating the reaction flask in an oil bath to obtain a Maillard product;

[0047] S400. Centrifuge the Maillard product using a centrifuge and take the supernatant to obtain a caramel-sweet flavor substance;

[0048] Among them, by weight, the raw materials include: 2-3 parts of concentrated sugarcane juice, 0.006-0.008 parts of glucose, 0.004-0.01 parts of glycine, 0.003-0.005 parts of alanine, 0.004-0.01 parts of phenylalanine, 0.004-0.01 parts of aspartic acid, and 1-1.5 parts of propylene glycol.

[0049] This application prepares caramel-sweet flavor substances by carrying out Maillard reaction on raw materials, enhancing the caramel feeling of the caramel-sweet flavor substances. Meanwhile, through the cooperation of each component, the caramel-sweet flavor substances have fresh, rich and natural caramel-sweet aroma, the aromas between each component are coordinated, and the caramel-sweet flavor is full, delicate, long-lasting and lingering, making the caramel-sweet flavor substances have both natural sweetness and a strong caramel feeling, solving the problem of single existing aroma.

[0050] Further, the temperature of the ultrasonic treatment is 40 - 50 °C; and / or,

[0051] the time of the ultrasonic treatment is 20 - 25 min; and / or,

[0052] the temperature of the oil bath heating is 100 - 150 °C; and / or,

[0053] the time of the oil bath heating is 4 - 5 h; and / or,

[0054] the time of centrifugation is 10 - 20 min; and / or,

[0055] the rotation speed of centrifugation is 4000 - 7000 r / min.

[0056] Ultrasonic treatment can make the raw materials fully dissolve and mix evenly, which is beneficial to the reaction between each component during subsequent heating. Adjust the pH value of the primary solution to 8 - 10. The alkaline environment helps the deprotonation of amino compounds, making it easier to react with reducing sugars, accelerating the rate of Maillard reaction, so as to generate more caramel-sweet flavor substances and provide richer and more complex aromas and tastes. Oil bath heating can provide uniform heat, making the primary solution heated evenly, avoiding local overheating or uneven heating, thus ensuring the stable progress of Maillard reaction. Using a tubular centrifuge can efficiently separate solid particles and liquid, remove impurities and precipitates in the Maillard products by centrifugation, thereby improving the purity of the products, making the color and flavor of the Maillard products more uniform, and enhancing the quality of the caramel-sweet flavor substances.

[0057] To solve the above technical problems, the embodiments of this application also provide a caramel-sweet flavor essence, adopting the following technical solutions:

[0058] A caramel-like flavor essence, by weight, the caramel-like flavor essence includes: 0.02 - 0.1 part of furfural, 1 - 3 parts of 3-methylcyclopentane-1,2-dione, 0.1 - 0.3 part of maltol, 1 - 4 parts of ethyl maltol, 0.05 - 0.1 part of vanillin, 0.1 - 0.2 part of ethyl vanillin, 0.05 - 0.3 part of 2,5-dimethylpyrazine, 0.03 - 0.2 part of 2,3,5-trimethylpyrazine, 0.002 - 0.05 part of γ-nonalactone, 0.03 - 0.3 part of furanone substances, 0.1 - 0.5 part of α-angelica lactone, 0.02 - 0.1 part of palmitic acid, 2 - 6 parts of propylene glycol, and the caramel-like flavor substance or the caramel-like flavor substance prepared by the preparation method of the caramel-like flavor substance;

[0059] Wherein, the addition amount of the caramel-like flavor substance in the caramel-like flavor essence is 1 - 2 parts.

[0060] This application uses the compounding effect between the caramel-like flavor substance obtained by the Maillard reaction and various chemical substances to prepare the caramel-like flavor essence. The caramel-like flavor essence has a unique caramel-like aroma. At the same time, the caramel-like flavor essence has both a natural sweet taste and a strong caramel taste. Through the cooperation of each component, the caramel-like flavor substance has a fresh, rich and natural caramel-like aroma. The aromas between the components are coordinated, and the caramel-like flavor is full, delicate, high in stability and long-lasting, solving the problem of single aroma in the prior art.

[0061] In order to solve the above technical problems, the embodiment of this application also provides an aerosol matrix, adopting the following technical scheme:

[0062] An aerosol matrix, by weight, the aerosol matrix includes: 0.5 - 3.5 parts of original flavor tobacco essence, 4 - 8 parts of solvent, and the caramel-like flavor essence;

[0063] Wherein, the addition amount of the caramel-like flavor essence in the aerosol matrix is 0.5 - 3.5 parts.

[0064] This application uses the compounding effect between the caramel-like flavor substance obtained by the Maillard reaction and various chemical substances to prepare the caramel-like flavor essence, and improves the flavor of the aerosol matrix by adding the caramel-like flavor essence to the aerosol matrix, enhancing the characteristic aroma of tobacco, making the aroma of caramel-like sweet and tobacco aroma in the atomized aerosol blend better, the smell is caramel-like and pleasant, the sweet taste is natural, the caramel taste is strong, the flavor coordination is better, and the atomization quality and aroma in the aerosol are both sufficiently persistent and stable, so that the sensory experience of users during the smoking process is better, solving the problem of single aroma in the prior art.

[0065] It is understandable that the weight parts of the burnt sweet flavor essence can be 0.5 part, 0.8 part, 1 part, 1.1 part, 1.2 parts, 1.3 parts, 1.4 parts, 1.5 parts, 1.6 parts, 1.7 parts, 1.8 parts, 1.9 parts, 2.0 parts, 2.5 parts, 3 parts, 3.5 parts in any numerical value or the scope formed by any two numerical values. The weight parts of the original tobacco flavor can be 0.5 part, 0.8 part, 1 part, 1.1 part, 1.2 parts, 1.3 parts, 1.4 parts, 1.5 parts, 1.6 parts, 1.7 parts, 1.8 parts, 1.9 parts, 2.0 parts, 2.1 parts, 2.5 parts, 3 parts, 3.5 parts in any numerical value or the scope formed by any two numerical values. The weight parts of the solvent can be 4 parts, 5 parts, 6 parts, 7 parts, 8 parts in any numerical value or the scope formed by any two numerical values.

[0066] Furthermore, the original tobacco flavor comprises, by weight: 1 to 2 parts of Yunyan absolute oil, 1 to 2 parts of burley tobacco absolute oil, 0.5 to 1 part of Virginia absolute oil, 0.005 to 0.02 parts of guaiacol, 0.005 to 0.02 parts of 4-vinylguaiacol, 0.01 to 0.02 parts of tree moss absolute oil, 0.01 to 0.03 parts of methylcyclopentenolone, 0.005 to 0.02 parts of hydroxyethyl ester, 0.005 to 0.01 ... 0.01 part of propylheptanolide, 0.005-0.01 part of 2-acetylpyridine, 0.003-0.005 part of 2,3,5-trimethylpyrazine, 0.01-0.03 part of megastigmatrienon, 0.001-0.05 part of 2-propyl-4-methyl-1,3-dioxolane, 0.02-0.1 part of benzyl alcohol, 0.1-0.5 part of ethanol and 2-6 parts of propylene glycol. The components of the original tobacco flavor are proportioned in specific contents, and the resulting composite solution can fully restore the original flavor of tobacco, and the aroma is long-lasting and stable, providing the original flavor of tobacco for the aerosol matrix and improving the user experience.

[0067] Furthermore, the aerosol matrix also includes nicotine, and the amount of nicotine added to the aerosol matrix is ​​0 to 2 parts by weight. Adding nicotine can significantly improve the throat hit of the aerosol, bringing satisfaction and pleasure, and can also improve the smoke taste and suction effect of the electronic cigarette, making it closer to traditional cigarettes.

[0068] It can be understood that the weight proportion of the nicotine can be any one of 0.05, 0.1, 0.15, 0.18, 0.19, 0.2, 0.21, 0.3, 0.4, 0.45, 0.5, 1, 1.5, 2, or a range formed by any two of the following values.

[0069] Furthermore, the solvent is selected from one or more of propylene glycol and glycerol. The solvent can help dissolve the original tobacco flavor and the caramel flavor, so that the aerosol matrix forms an aerosol after heating, improves the uniformity and stability of the aerosol matrix, and at the same time, propylene glycol and glycerol are healthy and environmentally friendly.

[0070] Furthermore, the total proportion of various substances in the caramel-sweet flavor substances, caramel-sweet flavor essences and aerosol matrix can be maintained at a specific proportion, such as 10 proportions. When adjusting the total proportion to maintain a specific proportion, it can be achieved by adjusting the proportion of the solvent, that is, increasing or decreasing the proportion of the solvent to achieve that the sum of the proportions of various substances is equal to a specific proportion.

[0071] Furthermore, the aerosol matrix further includes a cooling agent, and the amount of the cooling agent added to the aerosol matrix is ​​0 to 0.2 parts by weight. The cooling agent can stimulate the cold receptors in the mouth and throat, bringing a cool feeling, making the smoking experience more comfortable, while effectively reducing the irritation caused by the nicotine, making the smoking softer, and the synergistic effect of the cooling agent and the caramel sweet flavor essence further enhances the explosiveness of the caramel sweet flavor essence, making the smell more caramel-scented and pleasant, with a natural sweetness and a full caramel feeling.

[0072] It can be understood that the weight percentage of the cooling agent can be any one of 0.05 parts, 0.1 parts, 0.15 parts, 0.18 parts, 0.19 parts, 0.2 parts, or a range formed by any two of the values.

[0073] Furthermore, the cooling agent is selected from N,2,3-trimethyl-2-isopropylbutyramide. The cooling agent can stimulate the cold receptors in the mouth and throat, bringing a cool feeling, making the smoking experience more comfortable, while effectively reducing the irritation caused by the nicotine, making the smoking softer. Compared with menthol, WS-23 has no bitterness or spiciness, and the cooling feeling is long-lasting and non-irritating, which is suitable for long-term use.

[0102]

[0103]

[0104] Referring to Tables 1 and 2, according to Examples 1 to 9 and Comparative Example 1, it can be seen that the aroma restoration degree, aroma naturalness, aroma coordination, smoke volume, taste and comprehensive evaluation of Examples 1 to 9 are significantly improved compared with Comparative Example 1, which proves that adding caramel-sweet flavor essence to the aerosol matrix can improve the flavor of the aerosol matrix and enhance the characteristic aroma of tobacco, so that the caramel-sweet aroma and tobacco aroma in the aerosol after atomization are better integrated, the smell is pleasant, the sweetness is natural, the caramel feeling is full, the flavor coordination is better, the atomization quality and aroma in the aerosol are sufficiently durable and stable, so that the user's sensory experience in the smoking process is better, and the problem of single existing aroma is solved. This is because the caramel-sweet flavor essence is prepared by the complex action between the caramel-sweet flavor substance obtained by the Maillard reaction and a variety of chemical substances, which enhances the caramel feeling of the caramel-sweet flavor substance. At the same time, through the coordination of each component, the caramel-sweet flavor substance has a fresh, rich and natural caramel-sweet aroma.
