Description

Technical Field

[0001] The present invention relates to the field of atomization, and in particular to an electronic atomization liquid and an electronic atomization device. Background Art

[0002] The electronic atomization device converts the atomized liquid into an aerosol through an atomizer for human inhalation. By adding additives such as sweeteners to the atomized liquid, a rich taste and mouthfeel can be achieved, bringing a richer inhalation experience. Unlike traditional beverages and foods, the atomized liquid usually enters the mouth in the form of an aerosol after being atomized. The sweetener in the atomized liquid still mostly exists in the form of a sol after the aerosol enters the mouth, and the degree of contact with the taste bud cells is far less than that of liquid media such as beverages. Therefore, a higher concentration and sweetness of the atomized liquid is required to be atomized to generate an aerosol with a more suitable sweetness for inhalation. However, relying solely on increasing the concentration of sweeteners in the atomized liquid to increase the sweetness of the aerosol will bring many problems. For example, for common glycosides, dipeptides, and halogenated sucrose sweetener molecules, the structure will change during the high-temperature atomization process after the concentration is increased, resulting in serious deformation of the sweetness, which in turn affects the overall taste. In addition, high concentrations of sweetener molecules will accumulate on the heating element to form carbon deposits during the atomization process, which will have a serious impact on the taste and life of the electronic atomization device. Summary of the invention

[0003] Based on this, some embodiments of the present invention provide an electronic atomization liquid that has suitable sweetness after atomization and improves the problems of burning, carbon deposition and taste deformation during the atomization process.

[0007] In some embodiments, in the electronic atomization liquid, the mass fraction of the acidulant is 0.001 parts to 5 parts;

[0012] In some embodiments, in the electronic atomization liquid, the mass fraction of the sweetener is 2 to 15 parts;

[0013] Optionally, in the electronic atomization liquid, the mass fraction of the sweetener is 5 to 14 parts;

[0016] In some embodiments, the sweetener includes one or more of neotame, advantame, sucralose, steviol glycoside, glucosyl steviol glycoside and neohesperidin dihydrochalcone;

[0017] Optionally, in the sweetener, the mass ratio of neotame, advantame, sucralose, steviol glycoside, glucosyl steviol glycoside and neohesperidin dihydrochalcone is (1-3):1:(1-2):(1-4):(1-2):(1-4).

[0018] In some embodiments, the mass ratio of the sour agent to the sweetener is 1:(1-50);

[0025] An electronic atomization device comprises the electronic atomization liquid mentioned above.

[0026] The aerosol produced by the electronic atomization device is a thinner medium form compared to liquid media such as beverages. It is more difficult for it to carry sweeteners into the taste buds, and the human body can only feel the sweetness of sweeteners when they enter the taste buds. The inventors have found that in addition to the aerosol medium itself, saliva also plays a very important role. Saliva can help dissolve sweetener molecules and at the same time wash the mouth to achieve a new taste. The secretion of saliva depends on the stimulation of sour substances. Therefore, the inventors introduce suitable acidulants into the electronic atomization liquid, so that it enters the mouth with the aerosol to stimulate the production of saliva, assist in the rapid dissolution of sweeteners and achieve a high-sweetness taste. Experiments have shown that in the electronic atomization liquid, by combining the sweetener with a suitable acidulant, although the acidulant molecule itself does not have any sweetness, it forms a very strong and three-dimensional sweetness when combined with the sweetener. Compared with the atomization liquid containing high-concentration sweeteners, the atomization effect is better, which can bring a purer and more rounded high sweetness without burning or taste deformation during the atomization process. It can also bring a better taste and high sweetness during the long-term high-temperature atomization process, including high atomization fineness, obvious sense of salivation, fast sweetness release rate and good persistence, etc., avoiding or significantly improving possible bad smell and discomfort.

The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments.

[0039] As described in the background technology, typical electronic atomization liquid usually contains glycosides, dipeptides, halogenated sucrose and other sweetener molecules commonly used in beverages and foods. These sweeteners can provide stronger sweetness with lower calories. However, some high-sweetness sweetener molecules such as dipeptide sweeteners are prone to produce odor during high-temperature atomization. In addition, if the sweetness is increased only by increasing the concentration of sweeteners, it will often cause the atomization device to become blocked and the sweetness to be severely distorted, thus affecting the overall taste.

[0040] The inventor found in the study that the aerosol produced by the electronic atomization device will quickly fill the oral cavity, nasal cavity and throat cavity after being inhaled. The human body can feel sweetness mainly by relying on the taste buds growing in the oral cavity. The taste buds are bottle-shaped, and their main body is located inside the dermis, leading to the outside world through an opening located between the epithelial cells. When the sweetener molecules reach the vicinity of the tongue surface, they must enter the taste buds to produce sweet stimulation. Compared with beverages, the aerosol produced by the electronic atomization device is a thinner medium form, and it is more difficult for it to carry sweeteners into the taste buds. However, in addition to the aerosol medium itself, saliva also plays a very important role. Saliva can help dissolve sweetener molecules and wash the mouth to achieve taste renewal. The secretion of saliva depends on the stimulation of sour substances. Therefore, if suitable sour substances can be introduced into the electronic atomization liquid so that they can enter the mouth with the aerosol to stimulate the production of saliva, it can assist the rapid dissolution of sweeteners and achieve a high sweetness taste.

[0041] Based on this, the first aspect of the present invention provides an electronic atomization liquid, which includes 75 to 99.997 parts of a solvent, 0.002 to 15 parts of a sweetener, and 0.001 to 10 parts of an acidulant, based on 100 parts of the total mass of the electronic atomization liquid;

Further, in the electronic atomization liquid, the mass fraction of the solvent is 75 parts to 95 parts.

[0045] In some embodiments, the sweetener includes: a combination of one or more of neotame, advantame, sucralose, acesulfame potassium, steviol glycosides, glucosyl steviol glycosides, aspartame, hesperidin dihydrochalcone, neohesperidin dihydrochalcone (also known as neomethyl hesperidin dihydrochalcone) and naringin dihydrochalcone.

[0046] In one embodiment, the sweetener includes one or more of neotame, edavantin, sucralose, steviol glycoside, glucosyl steviol glycoside and neohesperidin dihydrochalcone. Further, the sweetener includes neotame, edavantin, sucralose, steviol glycoside, glucosyl steviol glycoside and neohesperidin dihydrochalcone.

[0047] In some of the embodiments, among the sweeteners, the mass ratio of neotame, advantame, sucralose, steviol glycoside, glucosyl steviol glycoside and neohesperidin dihydrochalcone is (1-3):1:(1-2):(1-4):(1-2):(1-4).

[0048] In a specific example, the sweetener includes 2 parts of neotame, 1 part of edavantin, 1 part of sucralose, 2 parts of steviol glycosides, 1 part of glucosyl steviol glycosides and 1 part of neohesperidin dihydrochalcone by mass.

[0050] In some embodiments, the acidulant includes glycyrrhizic acid, aconitic acid, gluconic acid and 2-methyl-2-pentenoic acid. In some embodiments, in the acidulant, the mass ratio of glycyrrhizic acid, aconitic acid, gluconic acid and 2-methyl-2-pentenoic acid is (10-15): (10-15): (7-10): 3.

[0051] Furthermore, the acidulant also includes one or more of acetic acid, propionic acid, butyric acid, oxalic acid, malic acid, succinic acid, fumaric acid, adipic acid, lactic acid, citric acid, levulinic acid, hydrochloric acid, tartaric acid, phosphoric acid, carbonic acid, tartaric acid, ascorbic acid, phytic acid, benzoic acid, salicylic acid, aspartic acid, hexenoic acid, 2,4-dimethyl-2-pentenoic acid, methylbutyric acid, glycyrrhetinic acid, ammonium glycyrrhizinate, sodium bicarbonate, sodium potassium hydrogen phosphate and sodium citrate.

Optionally, the mass fraction of the acidulant is 0.001 to 8. Further, the mass fraction of the acidulant is 0.001 to 5. Further, the mass fraction of the acidulant is 0.01 to 5.

[0054] In some embodiments, the mass ratio of the sour agent to the sweetener is 1:(1-50). For example, the mass ratio of the sour agent to the sweetener can be, but is not limited to, 1:1, 1:5, 1:10, 1:15, 1:20, 1:21, 1:22, 1:24, 1:25, 1:26, 1:28, 1:30, 1:35, 1:40, 1:45, 1:50 or a range consisting of any two of these values. Optionally, the mass ratio of the sour agent to the sweetener is 1:(20-30).

[0055] Although the above acidulant molecules themselves do not have any sweetness, they form a very strong and three-dimensional sweetness when combined with a small amount of sweeteners. Compared with the atomizer liquid containing high-concentration sweeteners, the atomization effect is better, and it can also bring a better taste and high sweetness during the long-term high-temperature atomization process, including atomization fineness, sweet taste, and salivation, which can avoid or significantly improve possible bad breath and discomfort.

[0056] In some embodiments, based on the total mass of the electronic atomization liquid as 100 parts, the electronic atomization liquid includes 75 to 99 parts of solvent, 2 to 15 parts of sweetener and 0.001 to 8 parts of acidulant. Further, based on the total mass of the electronic atomization liquid as 100 parts, the electronic atomization liquid includes 75 to 97 parts of solvent, 5 to 14 parts of sweetener and 0.01 to 5 parts of acidulant. Further, based on the total mass of the electronic atomization liquid as 100 parts, the electronic atomization liquid includes 75 to 95 parts of solvent, 8 to 12 parts of sweetener and 0.1 to 2 parts of acidulant.

[0057] In some embodiments, the electronic atomization liquid may also include one or more of flavors, nicotine salts, and cooling agents.

One or more combinations thereof. It should be noted that the flavor may contain one or more acidulant molecules. When calculating the amount of acidulant added, the calculation should be combined so that the total amount conforms to the component ratio of the electronic atomization liquid.

[0058] It is understood that the nicotine salt and the cooling agent may be commonly used in the art. For example, the nicotine salt may be a salt formed by nicotine and an organic acid, and the organic acid may be benzoic acid, tartaric acid, etc. The cooling agent may be, but is not limited to, menthol, menthone, isomenthone, WS-23 (N,2,3-trimethyl-2-isopropylbutyramide), WS-3 (N-ethyl-p-menthyl-3-carboxamide), WS-5 (N-(ethoxycarbonylmethyl)-p-alkane-3-carboxamide), WS-12 (N-(4-methoxyphenyl)-p-menthyl-7-carboxamide), neomenthol, isopulegol, menthyl acetate, isopulegyl acetate, menthyl isovalerate and pulegone, one or more thereof.

[0059] The inventors found that in the electronic atomization liquid, if the amount of sweetener is too much, although it can produce a higher sweetness, it will cause serious problems such as burning and carbon deposition, and the sweetness will decay rapidly with the increase in the number of puffs. If the amount of sour agent is too much and the amount of sweetener is too little, it will lead to problems such as low sweetness and sour taste. By combining sweeteners with sour agents, although the sour agent molecules themselves do not have any sweetness, they are combined with a small amount of sweeteners to form a very strong and three-dimensional sweetness. Compared with the atomization liquid containing a high concentration of sweeteners, the atomization effect is better, which can bring a purer and more rounded high sweetness without burning and taste deformation during the atomization process. It can also bring a better taste and high sweetness during the long-term high-temperature atomization process, including high atomization fineness, obvious sense of body fluid, fast sweetness release rate, and good durability, etc., to avoid or significantly improve possible bad breath and discomfort.

[0062] In order to make the purpose and advantages of the present invention clearer, the electronic atomization liquid of the present invention and its effects are further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and shall not be used to limit the present invention.

[0103] Six people who have passed the sensory ability assessment were selected to form an evaluation team. Sweetness, burnt bitterness and other peculiar smells were used as evaluation indicators to conduct sensory evaluation on the electronic atomization device equipped with Examples 1 to 8 and Comparative Examples 1 to 9. In order to eliminate the differences in the electronic atomization device, three parallel samples were arranged for each embodiment and comparative example. In order to eliminate the mutual influence between the samples, the evaluators used 200mL of pure water to clean the mouth and throat before evaluating each sample, and remained silent until the sweetness of the previous sample was completely dissipated. The perceived sweetness is divided into 9 levels in order from low to high, and each is scored 1-9 points. For specific scoring criteria, please refer to Table 1. The scores of the 6 personnel are averaged to obtain a comprehensive sweetness score, as shown in Table 3. The perceived roundness of the taste is divided into 9 levels in order from low to high, and each is scored 1-9 points. For specific evaluation criteria, please refer to Table 2. The scores of the 6 personnel are averaged to obtain a smoothness score, as shown in Table 3. When more than half of the six sensory panelists pointed out the presence of foreign smell or burnt bitter taste, the sample was considered to have foreign smell or burnt bitter taste.

[0108] Table 3 Sensory evaluation results of the electronic atomization liquid of each embodiment and comparative example

[0109]

[0110]

[0111] As can be seen from the results in Table 3, the electronic atomization liquids of Examples 1 to 3 show a very strong sweetness, which is compared with the electronic atomization liquids of Comparative Examples 1 to 3 without adding an acidulant, showing higher sweetness and smoothness. Similarly, Examples 4 to 8 show better sweetness and smoothness than the comparative examples. For Comparative Example 6, no acidulant was added, but the concentration of the sweetener was increased. Although a high sweetness was formed, a serious burnt bitterness was presented, which affected the inhalation experience. In Comparative Examples 4 to 5, although an acidulant was added, the sweetener was still too much, which was easy to produce odor and low smoothness, and also produced a serious burnt bitterness. In Comparative Examples 7 to 8, although an acidulant was added, the acidulant did not contain glycyrrhizic acid, aconitic acid, gluconic acid and 2-methyl-2-pentenoic acid at the same time. Although no burnt bitterness was produced, the sweetness and smoothness values ​​were significantly lower. In Comparative Example 9, only an acidulant was added, but no sweetener was added, resulting in a serious lack of sweetness and a low smoothness value. From this, it can be seen that by combining sweeteners and sour agents, the electronic atomization liquid can achieve a high sweetness, which can bring a significant sense of salivation and sweetness compared to the aerosol produced by the electronic atomization liquid with sweeteners added alone.
