Description

Technical Field

[0001] The present invention relates to the technical field of sweeteners, and particularly relates to a sweet composition, a preparation method thereof, and an atomization liquid. Background Art

[0002] In addition to the main components such as glycerol, propylene glycol, and flavors, the e-cigarette atomization liquid generally also contains components that can provide oral taste, such as cooling agents, sweeteners, etc. These components that can provide flavors can greatly improve the sensory experience of the e-cigarette atomization liquid. Among them, the sweetener can endow the e-cigarette aerosol with a richer taste, and at the same time can make the flavor closer to natural, and is an indispensable component in the e-cigarette atomization liquid.

[0003] At present, the mainstream atomization core structures of e-cigarettes are cotton cores and ceramic cores. Commonly used sweeteners in e-cigarette atomization liquids are mostly sucralose, neotame, or a composite of the two. Sucralose has a sweet taste in the middle, a single sweet feeling, insufficient heat resistance, and carbon deposition and wicking problems are likely to occur when the addition amount is large, affecting the taste. Neotame belongs to a high-potency sweetener, with a pure sweet taste, a low sweetness when entering the mouth, and an obvious aftertaste at high concentrations. When the addition amount is large, an unpleasant greasy sweet feeling in the mouth and throat is likely to occur, especially a bitter taste is more likely to occur in the ceramic core. Although the composite of the two can solve some of the above problems, the problems of wicking and bitterness still cannot be solved. Summary of the Invention

[0027] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0028] It should be noted that, in the embodiments, those without specifying specific conditions are carried out according to normal conditions or conditions recommended by the manufacturer. Those without specifying the manufacturer of reagents or instruments used are conventional products that can be purchased commercially. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes, and "A and / or B" is taken as an example, including schemes A, B, or A and B that meet the same time. In addition, the technical schemes between the various embodiments can be combined with each other, but must be based on the ability of ordinary technicians in the field to achieve. When the combination of the technical schemes is contradictory or cannot be achieved, it should be considered that the combination of such technical schemes does not exist, and is not within the scope of protection required by the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work, all belong to the scope of protection of the present invention.

[0029] At present, the mainstream structure of the atomization core of electronic cigarettes is cotton core and ceramic core. The commonly used sweeteners in the atomization liquid of electronic cigarettes are mostly sucralose, neotame or a compound of the two. Sucralose is sweet in the middle, with a single sweetness and insufficient heat resistance. When added in large amounts, it will dissolve and cause carbon deposition and sticking to the core, affecting the taste. Neotame is a high-power sweetener with pure sweetness, low sweetness when entering the mouth, and obvious after-sweetness at high concentrations. When added in large amounts, it is easy to have an unpleasant greasy sweet feeling in the mouth and throat, especially in ceramic cores, it is more likely to taste bitter. Although the compound of the two can solve some of the above problems, the problems of sticking to the core and bitterness still cannot be solved.

[0030] In view of the above problems, the present invention provides a sweetening composition comprising the following raw material components: sucralose, neotame, rebaudioside A (Reb-A), rebaudioside M (Reb-M), advantame and a solvent.

[0031] It should be noted that rebaudioside in rebaudioside A and rebaudioside M is the translation of Rebaudioside, which is also translated as lebaudioside, stevioside, etc. Therefore, rebaudioside A can be abbreviated as Reb-A, and rebaudioside M can be abbreviated as Reb-M.

[0032] In the technical solution provided by the present invention, sucralose, neotame, rebaudioside A, rebaudioside M and advanceantame are dispersed and dissolved by using a solvent, so that the various sweeteners cooperate with each other to form a unique sweetness, thereby improving the sweetness, sweetness stability and high temperature resistance of the sweetness composition.

[0033] Among them, the sweetness of sucralose is 400 to 600 times that of sucrose. The speed of sweetness presentation, the intensity of maximum sweetness perception, the duration of duration and the aftertaste are all close to sucrose, but the taste area is different from sucrose, belonging to the front and middle sweetness; the sweetness of neotame is 6000-10000 times that of sucrose, with a stable structure and pure sweetness. It can remain stable under instantaneous high temperature conditions. The sweetness is low in the mouth, but the middle and after sweetness are obvious at high concentrations, and the retention time is long, which is easy to cause greasy sweetness; the sweetness of Advantame is It is 20,000 times sweeter than sucrose, and its structure is more stable than neotame at high temperatures. It has a pure and refreshing sweetness, and is sweet at the beginning. When added in high concentrations, the aftersweetness is not obvious. Reb-A is a type of steviol glycoside, and its sweetness is 450 times that of sucrose. Its sweetness is close to that of sucrose, and it has no bad aftertaste. When added in high concentrations, it will have a bitter and licorice aftertaste. Reb-M is 450 times sweeter than sucrose, and its sweetness is close to that of sucrose. When added in high concentrations, it will not produce the bitter and licorice aftertaste similar to Reb-A, and will not affect the flavor senses.

[0034] By using neotame, the main sweetness is provided, and the combination with sucralose makes the sweetness more natural. There is a synergistic effect, which makes the sweetness present a good mid-after sweetness. Neotame is prone to sweetness decay at high temperatures, while Advantine has high heat stability. By adding Advantine, the sweetness decay during long-term heating can be compensated and the sweetness stability can be maintained. In addition, Advantine will provide a more natural front sweetness, thereby compensating for the lack of front sweetness of the combination of sucralose and neotame. Reb-A and Reb-M are special diterpenoid compounds, belonging to flavonoids, which can inhibit the bitterness brought by neotame and improve the sweetness.

[0035] Further, the sweet composition comprises the following raw material components in parts by mass: 4-8 parts of sucralose, 8-12 parts of neotame, 6-9 parts of rebaudioside A, 3-6 parts of rebaudioside M, 0.8-1.5 parts of advantame, and 63.5-78.2 parts of solvent. By using 63.5-78.2 parts of solvent, while ensuring the sweet taste of the sweet composition, the uniformity of each sweetener is improved; if the added amount of the solvent is less than 63.5 parts, it is difficult for each sweetener to be dispersed and dissolved evenly, resulting in a decrease in the uniformity of the sweet composition, and further reducing the stability of the sweet composition; if the added amount of the solvent is more than 78.2 parts, the sweetness of the sweet composition will decrease. Preferably, in an embodiment of the present invention, the sweet composition comprises the following raw material components in parts by mass: 6 parts of sucralose, 10 parts of neotame, 8 parts of rebaudioside A, 4 parts of rebaudioside M, 1 part of advantame, and 71 parts of solvent.

[0036] In addition, the solvent comprises at least one of water, propylene glycol, glycerol and ethanol. Water, propylene glycol, glycerol and ethanol all have the advantages of low cost, low toxicity, high volatility and good dissolution effect. Preferably, in an embodiment of the present invention, the solvent comprises propylene glycol. Compared with ethanol, propylene glycol has lower toxicity and no miscellaneous taste to highlight the sweet taste of the sweet composition; compared with water and glycerol, propylene glycol has moderate viscosity and stronger antifreeze property to expand the application temperature range of the sweet composition.

[0037] The present invention also provides a preparation method of a sweet composition for preparing the sweet composition, and the sweet composition comprises the following raw material components: sucralose, neotame, rebaudioside A, rebaudioside M, advantame and solvent;

[0038] The preparation method of the sweet composition comprises the following steps:

[0039] S10. Mix sucralose, neotame, rebaudioside A, rebaudioside M and advantame and then pulverize to obtain a mixed powder;

[0040] S20. Obtain the solvent, heat and shear-disperse it, add the mixed powder and mix to obtain a mixed liquid;

[0041] S30. Let the mixed liquid stand and then filter to obtain the sweet composition.

[0042] By mixing and pulverizing each sweetener, the dissolution rate of the mixed powder is accelerated; by heating and shear-dispersing the mixture, the dissolution rate of the mixed powder can be further accelerated; by letting the mixed liquid stand and then filtering, the bubbles and insoluble substances in the mixed liquid can be removed, and the uniformity and stability of the sweet composition are improved.

[0043] Further, step S10 includes:

[0044] After mixing sucralose, neotame, rebaudioside A, rebaudioside M and advantame, airflow ultrafine grinding is carried out to obtain a mixed powder.

[0045] By carrying out airflow ultrafine grinding, each sweetener can be ground into a mixed powder with a smaller particle size. Moreover, there are no metal blades during the airflow ultrafine grinding process, so metal particles will not be mixed into the mixed powder due to the blades, improving the uniformity of the mixed powder and facilitating the improvement of the uniformity and stability of the sweet composition.

[0046] In addition, step S20 includes:

[0047] Preheat the solvent to 40 - 60 °C, add the mixed powder while shearing and dispersing at 8000 - 16000 rpm for 40 - 50 min to obtain a mixed liquid.

[0048] By preheating the solvent, the solubility of each sweetener in the solvent is increased and the dissolution rate is accelerated; by shearing and dispersing, the mixed powder is mixed into the solvent, further improving the dispersion uniformity of the mixed powder in the solvent, thereby further improving the uniformity and stability of the sweet composition.

[0049] Furthermore, step S30 includes:

[0050] After standing the mixed liquid for 4 - 6 h, filter it with a filter having a filtration diameter of 10 - 20 μm to obtain the sweet composition.

[0051] By standing the mixed liquid for 4 - 6 hours, the bubbles and sediment in the mixed liquid are respectively agglomerated for easy filtration; if the standing time is less than 4 hours, the bubbles and sediment cannot be fully agglomerated and filtered out, and are partially dispersed in the mixed liquid, affecting the taste and smell of the sweet composition; if the standing time is more than 6 hours, the bubbles and sediment do not increase significantly, and too long a time will cause the sweetener to deteriorate, affecting the taste and smell of the sweet composition.

[0052] The present invention also provides an atomized liquid, which includes a sweet composition, and the sweet composition includes the following raw material components: sucralose, neotame, rebaudioside A, rebaudioside M, advantame and a solvent.

[0053] For the specific beneficial effects of the sweet composition, refer to the above embodiments. Since this atomized liquid adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.

[0054] Furthermore, the atomized liquid includes the following raw material components in parts by mass:

[0055] 1 - 5 parts of sweet composition, 15 - 20 parts of essence, 30 - 50 parts of propylene glycol, 30 - 50 parts of glycerol.

[0056] By using the sweetening composition and the flavoring agent in combination, the sweetness, richness and fineness of the sweetening composition are further enhanced. Preferably, the atomized liquid comprises the following raw material components in parts by mass: 2 parts of sweetening composition, 18 parts of flavoring agent, 40 parts of propylene glycol, and 40 parts of glycerol.

[0057] It should be noted that the flavoring agent can be a daily-use flavoring agent or an edible flavoring agent, which is not limited herein as long as it can be paired with the sweetening composition and emit an aroma when heated. Specifically, in an embodiment of the present invention, the flavoring agent is a fruit-flavored tobacco flavoring agent, which is combined with the sweetening composition to enhance the sweetness, richness and fineness of the atomized liquid after atomization.

[0058] The technical solution of the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the following embodiments are only used to explain the present invention and are not used to limit the present invention.

The sum of the mass parts of the raw material components of each example and comparative example is 100 parts. Among them, the raw material components of Comparative Example 1 are the raw material components of Example 1 in which Reb-A and Reb-M are replaced by propylene glycol, the raw material components of Comparative Example 2 are the raw material components of Example 1 in which advantame is replaced by propylene glycol, the raw material components of Comparative Example 3 are the raw material components of Example 1 in which Reb-A, Reb-M and advantame are replaced by propylene glycol and the mass part of sucralose is adjusted to 10 parts, and the raw material components of Comparative Example 4 are the raw material components of Example 1 in which sucralose, Reb-A, Reb-M and advantame are replaced by propylene glycol.

[0066] Smoking evaluation comparison experiment

[0067] Adopt a vertically launched, net-shaped disposable cotton core device. A group of 10 people each evaluated the puffing of Examples 8 to 16 and Comparative Examples 6 to 10. Remove one highest score and one lowest score, and take the approximate value of the arithmetic mean accurate to the nearest whole number as the puffing result for each item. The puffing method is a whole-cycle puffing. After inhaling the smoke into the mouth, pause for 2 to 4 seconds, swallow the smoke through the throat, and then slowly exhale it from the nasal cavity.

[0068] The scoring criteria are shown in Table 3.

[0069] Table 3 Scoring Criteria for Puffing Comparative Experiments

[0070]

[0071]

[0072] According to the above scoring criteria, a puffing comparative experiment was conducted, and the results of the puffing comparative experiment are shown in Table 4.

[0073] Table 4 Results of Puffing Comparative Experiments for Examples 8 to 16 and Comparative Examples 6 to 10

[0074]

[0075] From the data in the above table, it can be seen that the total puffing scores of the atomizing liquids provided in Examples 8 to 16 of the present invention are all higher than 80 points, while the total puffing scores of the atomizing liquids provided in Comparative Examples 6 to 10 are all lower than 70.

[0076] The raw material components of Comparative Example 6 are the raw material components of Example 8 with Reb-A and Reb-M replaced by propylene glycol. It is not difficult to conclude that the richness and fineness of Comparative Example 6 are slightly reduced, while the sweetness, off-flavors, and aftertastes are significantly decreased, proving that the addition of Reb-A and Reb-M can significantly improve the sweetness of the atomizing liquid and solve the problems of excessive off-flavors and insufficient aftertastes.

[0077] The raw material components of Comparative Example 7 are the raw material components of Example 8 with advantame replaced by propylene glycol. It is not difficult to conclude that the richness and off-flavor performance of Comparative Example 7 are slightly decreased, while the sweetness, fineness, and aftertaste are significantly decreased, proving that the addition of advantame can significantly improve the sweetness and fineness of the atomizing liquid and solve the problem of insufficient aftertaste.

[0078] The raw material components of Comparative Example 8 are the raw material components of Example 8 with Reb-A, Reb-M, and advantame replaced by propylene glycol and the mass fraction of sucralose in the sweetening composition adjusted to 10 parts. It is not difficult to conclude that the richness of Comparative Example 8 is slightly reduced, while the sweetness, smoothness, off-flavors, and aftertaste performance all decrease significantly, proving that the addition of Reb-A, Reb-M, and advantame can significantly improve the sweetness and smoothness of the aerosol liquid and improve the problems of excessive off-flavors and insufficient aftertaste. Further, compared with Comparative Example 6 and Comparative Example 7, the aftertaste score of Comparative Example 8 is lower, indicating that Reb-A, Reb-M, and advantame have a synergistic effect to improve the insufficient aftertaste problem of the aerosol liquid.

[0079] The raw material components of Comparative Example 9 are the raw material components of Example 16 with sucralose, Reb-A, Reb-M, and advantame replaced by propylene glycol. It is not difficult to conclude that the sweetness of Comparative Example 9 is slightly reduced, while the richness, smoothness, off-flavors, and aftertaste performance all decrease significantly, proving that the addition of sucralose, Reb-A, Reb-M, and advantame can significantly improve the richness and smoothness of the aerosol liquid and improve the problems of excessive off-flavors and insufficient aftertaste.

[0080] In the raw material components of Comparative Example 10, the mass components of the sweeteners added are all higher than the scope of this solution, while the mass component of propylene glycol is lower than the scope of this solution. It is not difficult to find that compared with Example 8, the scores of the richness and aftertaste of Comparative Example 10 do not decrease significantly, but the scores of sweetness, smoothness, and off-flavors decrease significantly; it is proved that too high a content of sweeteners leads to mixed sweetness, resulting in no obvious distinction between the initial sweetness and the subsequent sweetness and a decrease in smoothness; too much sweetener is added, resulting in some sweeteners being difficult to disperse and dissolve, and the sweetness decreases; adding a high concentration of sweeteners to the aerosol liquid is prone to gelatinization, resulting in a coke flavor and a metallic bitter taste, and the off-flavor performance is poor.

[0081] Further, compared with Comparative Example 8, the sweetness of Comparative Example 9 actually increases. This is because the addition amount of the sweetening composition in the aerosol liquid provided in Comparative Example 9 is 4 mass parts, while the addition amount of the sweetening composition in Comparative Example 8 is 2 mass parts. In addition, the aftertaste performance of Comparative Example 9 is improved compared with Comparative Example 8, indicating that sucralose will affect the aftertaste performance of the aerosol liquid. Compared with Comparative Example 7, Comparative Example 9 does not add sucralose, Reb-A, and Reb-M, but its aftertaste performance does not change significantly, indicating that the addition of Reb-A and Reb-M helps to improve the effect of sucralose in reducing the aftertaste performance. Therefore, there is a certain synergistic and antagonistic effect among advantame, neotame, sucralose, Reb-A, and Reb-M.

[0082] Smoking machine suction comparison experiment

[0083] The wick and ceramic core were used to atomize the atomization liquids provided in Example 8 and Comparative Example 8 and Example 16 and Comparative Example 9 respectively, and a smoking machine was used to simulate the sucking action of a human. The sucking parameters of the smoking machine were set as follows: the number of sucking puffs was 600, the return rate was 20 ml / s, the volume per puff was 55 ml, the sucking time was 2 s, the interval between each puff was 10 s, and the inhalation-exhalation interval was 2 s. After the sucking was completed, the wick or ceramic core was taken out to observe the influence of different atomization liquids on the sucking test results.

[0084] The results of the smoking machine sucking comparison experiment using the wick are as Figure 1 shown. Figure 1 The left side shows the sucking test results of Comparative Example 8. Figure 1 The right side shows the sucking test results of Example 8. By comparing the sucking test results of Comparative Example 8 and Example 8, it is not difficult to find that there is serious carbon deposition on the wick of Comparative Example 8, while there is no carbon deposition on the wick of Example 8, and the aroma emitted by the wick is normal without obvious off-flavors.

[0085] The results of the smoking machine sucking comparison experiment using the ceramic core are as Figure 2 shown. Figure 2 The left side shows the sucking test results of Comparative Example 9. Figure 2 The right side shows the sucking test results of Example 16. By comparing the sucking test results of Comparative Example 9 and Example 16, it is not difficult to find that there is serious carbon deposition on the heating wire of Comparative Example 9 and an obvious metallic bitter taste is emitted, while there is no carbon deposition on the heating wire of Example 16, and the aroma emitted by the ceramic core is normal with a delicate and rich sweet taste without obvious off-flavors.

[0086] Combined with Figure 1 Figure 2 It can be seen that Example 8 has stronger high-temperature resistance compared with Comparative Example 8 without adding Reb-A, Reb-M and advantame, and Example 16 has stronger high-temperature resistance compared with Comparative Example 9 without adding sucralose, Reb-A, Reb-M and advantame. This shows that although neotame has certain high-temperature resistance, carbon deposition on the core will also occur under long-term continuous heating and sucking, and the synergistic effect of sucralose and neotame is limited and cannot completely improve the problem of carbon deposition on the core. Mixing sucralose, neotame, Reb-A, Reb-M and advantame in proportion, and the components synergize with each other, which can further improve the high-temperature resistance of the atomization liquid and significantly improve the problem of carbon deposition on the wick and ceramic core during the heating of the atomization liquid.

[0087] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the patent protection scope of the present invention.
