Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cigarettes, and particularly relates to a flavor tipping paper, a preparation method thereof and a cigarette. BACKGROUND

[0002] Tipping paper is an important component of a cigarette, which can connect a filter rod and a cigarette together. Since the tipping paper does not participate in combustion and is directly in contact with the oral cavity, adding characteristic substances to the tipping paper can have an important impact on the smoking experience of a cigarette. In recent years, with the emphasis of consumers on health and the pursuit of differentiation and personalization of cigarette products by consumers, various cigarette companies add characteristic substances, especially sweeteners, to the tipping paper to enable consumers to experience different experiences when smoking. Since ginsenosides have various beneficial effects such as antioxidant, anti-inflammatory and anti-diabetic effects, they are very suitable for the current development trend of cigarettes. Adding ginsenosides to the tipping paper is beneficial to the health of consumers, and adding sweeteners can improve the smoking experience of cigarettes.

[0003] CN114108388A discloses a cigarette tipping paper containing ginsenosides and a preparation method thereof as well as a cigarette. Ginsenosides are dissolved in ethanol and then added to the surface of the tipping paper. However, ethanol cannot completely dissolve ginsenosides, but only a part of them, and the dissolution process is slow, resulting in a low content of effective components of ginsenosides and a complicated filtration process. Therefore, only a small amount of ginsenosides can be filtered, and the efficiency is not high, which cannot be used for mass production. SUMMARY

[0004] Therefore, the present application aims to provide a flavor tipping paper, a preparation method thereof and a cigarette. The flavor tipping paper contains ginsenosides and sweeteners, and can be mass-produced.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] In a first aspect, the present application provides a flavor tipping paper, which comprises a tipping paper and a coating layer compounded on the surface of the tipping paper, wherein the coating layer is formed by ginsenosides, sweeteners and modified gloss oil.

[0007] The modified gloss oil comprises gloss oil and water-based acrylic resin.

[0008] Preferably, the mass ratio of the gloss oil to the water-based acrylic resin is (92-98):(2-8).

[0009] Preferably, the total content of the ginsenosides is greater than 750 μg / g based on the total mass of the tipping paper.

[0010] Preferably, the effective components of the ginsenosides are >80%.

[0011] Preferably, the mass ratio of the ginsenoside, the sweetener and the modified varnish is 1:(0.5-2):(50-100).

[0012] Preferably, the sweetener is selected from one or more of sucralose, neotame, sodium saccharin or stevioside.

[0013] In a second aspect, the present application provides a method for preparing the above-mentioned flavored tipping paper, comprising the following steps:

[0014] A ginsenoside solution, a sweetener solution and a modified varnish are provided.

[0015] The flavored tipping paper is obtained by printing on the surface of the tipping paper.

[0016] Preferably, the ginsenoside solution is a mixed solution of ginsenoside, water and ethanol.

[0017] Preferably, the sweetener solution is a mixed solution of sweetener, water and ethanol.

[0018] The ethanol is 95vol% ethanol.

[0019] Preferably, the mass ratio of the ginsenoside, water and ethanol is (0.1-0.2):1:(1-4).

[0020] Preferably, the mass ratio of the sweetener, water and ethanol is (0.05-0.4):1:(1-4).

[0021] In a third aspect, the present application provides a cigarette comprising tobacco, cigarette paper, tipping paper, formed paper and filter rod.

[0022] The tipping paper is selected from the above-mentioned flavored tipping paper.

[0023] Compared with the prior art, the present application has the following advantages:

[0024] The present application provides a flavored tipping paper, which is coated with ginsenoside, sweetener and modified varnish by an offline coating process. Meanwhile, by using varnish and modified varnish of water-based acrylic resin, the present application can avoid the problem that flocculation is precipitated after water is added to ordinary varnish during coating, and coating cannot be performed. Ginsenoside has various beneficial effects such as antioxidant, anti-inflammatory and anti-diabetic effects, and is more in line with the current development trend of harm reduction and focus reduction. In the present application, the effective component of ginsenoside is more than 80%, and the coating amount of ginsenoside and sweetener can be adjusted according to actual needs. By using the flavored tipping paper provided by the present application, ginsenoside can be directly contacted with the oral cavity, and the activity of the effective component of ginsenoside is maximized. At the same time, due to the presence of sweetener, the slight bitterness of ginsenoside can be effectively avoided. BRIEF DESCRIPTION OF DRAWINGS

[0033] The technical solutions of the present application will be described clearly and completely below in combination with the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] In the prior art, ginsenoside is dissolved in ethanol and then added to the surface of tipping paper. However, the dissolution process is slow, which leads to low effective content of ginsenoside and complicated processing. The present application provides a flavored tipping paper, which comprises tipping paper and a coating layer compounded on the surface of the tipping paper, and the coating layer is formed by ginsenoside, sweetener and modified varnish. The modified varnish comprises varnish and water-based acrylic resin, and the mass ratio of the varnish to the water-based acrylic resin is (92-98):(2-8), more preferably (93-95):(5-7). Within the above range, after the addition of ginsenoside solution, the modified varnish does not appear to precipitate flocculation, and the whole varnish solution system is uniformly mixed without precipitation or precipitation.

[0035] In some embodiments of the present application, the structure diagram of the flavored tipping paper is shown in Figure 1 , which comprises:

[0036] Tipping paper;

[0037] A ginsenoside layer, a sweetener layer, and a modified varnish layer are stacked on the surface of the tipping paper.

[0038] It should be noted that the upper and lower positional relationship of the ginsenoside layer, sweetener layer, and modified varnish layer is not unique. Figure 1 The position shown can be any of the following structures: tipping paper - ginsenoside layer - sweetener layer - modified varnish layer; tipping paper - ginsenoside layer - modified varnish layer - sweetener layer; tipping paper - sweetener layer - ginsenoside layer - modified varnish layer; tipping paper - sweetener layer - modified varnish layer - ginsenoside layer; tipping paper - modified varnish layer - ginsenoside layer - sweetener layer; tipping paper - modified varnish layer - sweetener layer - ginsenoside layer.

[0039] In the above structure, the ginsenoside layer, the sweetener layer, and the modified varnish layer completely cover the entire surface of the corresponding layer structure.

[0040] In some embodiments of the present invention, see the structural schematic diagram of the flavored tipping paper. Figure 2 ,include:

[0041] Packing paper;

[0042] A ginsenoside layer, a sweetener layer, and a modified varnish layer are stacked on the surface of the tipping paper.

[0043] Similarly, the upper and lower positional relationship of the three layers is as described in the relevant content of the above technical solution, and will not be repeated here. Figure 1 The difference shown is that, in Figure 2 In the structure shown, the three layers do not completely cover the entire surface of the corresponding layer structure during the stacking process.

[0044] In some embodiments of the present invention, see the structural schematic diagram of the flavored tipping paper. Figure 3 ,include:

[0045] Packing paper;

[0046] A mixed layer and a single layer are stacked on the surface of the tipping paper;

[0047] The mixed layer is composed of any two of ginsenosides, sweeteners, or modified varnishes; correspondingly, the single layer is composed of the remaining substances from ginsenosides, sweeteners, or modified varnishes other than any two combinations mentioned above. That is, if the mixed layer is composed of ginsenosides and sweeteners, then the single layer is composed of modified varnishes. Other configurations can be derived by analogy.

[0048] exist Figure 3In the structure shown, the upper and lower positions of the mixed layer and the single layer are not limited, and they completely cover the corresponding layer surface. However, it should be noted that the mixed layer and the single layer can also not completely cover the corresponding layer surface, and for the sake of simplicity, no further illustration is provided.

[0049] In some embodiments of the present application, the structure of the flavor tipping paper is shown in Figure 4 , which comprises:

[0050] tipping paper;

[0051] a mixed layer of ginsenoside, sweetener and modified gloss oil arranged on the surface of the tipping paper.

[0052] In the present application, the modified gloss oil in the above-mentioned structure is preferably in direct contact with the tipping paper, so that the ginsenoside and the sweetener contained in the gloss oil are more directly perceived by the smoker. At the same time, the ginsenoside, the sweetener and the gloss oil are prepared into a mixed layer, which has the advantages of reducing processing procedures and saving costs.

[0053] Since ginsenoside has various beneficial effects such as antioxidant, anti-inflammatory and anti-diabetic effects, it is very suitable for the current development trend of cigarettes. Adding it to the tipping paper is beneficial to the health of consumers, and adding the sweetener can improve the smoking experience of cigarettes, so the present application combines it in the tipping paper. In the present application, the ginsenoside can be prepared by itself or purchased directly from commercially available products, and its source is not specifically limited. Specifically, the total content of the ginsenoside is greater than 750 μg / g, preferably greater than 760 μg / g, based on the total mass of the flavor tipping paper, and the effective component of the ginsenoside is > 80%.

[0054] In the present application, the sweetener can effectively avoid the slight bitterness of ginsenoside during smoking, and it can be purchased directly from commercially available products, and its source is not specifically limited. Specifically, the sweetener can be selected from one or more of sucralose, neotame, sodium saccharin or stevioside.

[0055] In the present application, the mass ratio of the ginsenoside, the sweetener and the modified gloss oil is 1:(0.5-2):(50-100), which can ensure that the ginsenoside and the sweetener can be fully dissolved in the modified gloss oil, and the ginsenoside content and the sweetness of the finished tipping paper are appropriate.

[0056] The present application also provides a preparation method of the above-mentioned flavor tipping paper, which is shown in Figure 1 , which comprises the following steps:

[0057] providing a mixed solution of ginsenoside, water and ethanol; a mixed solution of sweetener, water and ethanol;

[0058] The improved light oil, the mixed solution of sweetener, water and ethanol, the mixed solution of ginsenoside, water and ethanol are printed on the surface of the tipping paper in sequence to obtain the flavored tipping paper.

[0059] Specifically, first, a certain amount of ginsenoside (effective component ≥80%) and sweetener are weighed and added into water in corresponding proportions, and stirred to completely dissolve.

[0060] Then the improved light oil, the mixed solution of sweetener, water and ethanol, the mixed solution of ginsenoside, water and ethanol are printed on the surface of the tipping paper in sequence to obtain the flavored tipping paper.

[0061] The application also provides a preparation method of the flavored tipping paper. Figure 2 The structure shown in the figure is taken as an example, and the method comprises the following steps:

[0062] The improved light oil is printed on the surface of the tipping paper, and then the mixed solution of ginsenoside, water and ethanol, the mixed solution of sweetener, water and ethanol are sprayed on the surface of the tipping paper to obtain the flavored tipping paper.

[0063] The preparation of the mixed solution of ginsenoside, sweetener, water and ethanol is described above.

[0064] The obtained mixed solution is preferably sprayed on the surface of the tipping paper, and more preferably at a position 1.5-2 cm away from the end of the tipping paper to obtain the flavored tipping paper.

[0065] The application also provides a preparation method of the flavored tipping paper. Figure 3 The structure shown in the figure is taken as an example,

[0066] The mixed solution of ginsenoside, sweetener, water and ethanol is provided, and then the improved light oil and the mixed solution are printed on the surface of the tipping paper in sequence to obtain the flavored tipping paper.

[0067] Specifically, first, a certain amount of ginsenoside (effective component ≥80%) and sweetener are weighed and added into water in corresponding proportions, and stirred to completely dissolve.

[0068] Then the improved varnish, mixed solution are printed on the surface of the tipping paper in turn, and the flavor tipping paper is obtained.

[0069] The application also provides a preparation method of the flavor tipping paper. Figure 4 The structure is shown as an example, comprising the following steps:

[0070] The mixed solution of ginsenoside, sweetener, water and ethanol is mixed with the improved varnish and printed on the surface of the tipping paper to obtain the flavor tipping paper.

[0071] The preparation of the mixed solution of ginsenoside, sweetener, water and ethanol is described above.

[0072] The mixed solution of ginsenoside, sweetener, water and ethanol is mixed with the improved varnish and printed on the surface of the tipping paper to obtain the flavor tipping paper.

[0073] The printing method is not particularly limited and is a printing method known to those skilled in the art.

[0074] In the application, the mass ratio of the sweetener, water and ethanol in the mixed solution of the sweetener, water and ethanol is (0.05-0.4):1:(1-4); the mass ratio of the ginsenoside, water and ethanol in the mixed solution of the ginsenoside, water and ethanol is (0.1-0.2):1:(1-4); and the mass ratio of the ginsenoside, sweetener, water and ethanol in the mixed solution of the ginsenoside, sweetener, water and ethanol is (0.1-0.2):(0.05-0.4):1:(1-4). Within the range, the ginsenoside and the sweetener can be fully dissolved, and when the solution is added to the improved varnish, the improved varnish does not precipitate in the form of flocculation, the whole varnish solution system is uniformly mixed, and there is no precipitation or precipitation.

[0075] The application also provides a cigarette, comprising tobacco, cigarette paper, tipping paper, formed paper and filter rod.

[0076] The tipping paper is selected from the flavor tipping paper.

[0077] The application provides a flavor tipping paper, which is coated with ginsenoside, sweetener and modified gloss oil on the surface by an offline coating process. The application can avoid the problem that flocculation is precipitated after water is added to ordinary gloss oil during coating, and coating cannot be performed, by using the modified gloss oil of gloss oil and water-based acrylic resin. The ginsenoside has various beneficial effects such as antioxidant, anti-inflammatory and anti-diabetic effects, and is more in line with the development trend of harm reduction and focus reduction. In the application, the effective component of the ginsenoside is more than 80%, and the coating amount of the ginsenoside and the sweetener can be adjusted according to actual needs. The flavor tipping paper provided by the application can make the ginsenoside directly contact the oral cavity, thereby maximizing the activity of the effective component of the ginsenoside, and the slight bitter taste of the ginsenoside can be effectively avoided due to the presence of the sweetener.

[0078] In order to further illustrate the application, the following examples are used for detailed description. The experimental raw materials used in the following examples of the application are all general commercially available products.

[0079] Example 1

[0080] According to the formula in Table 1, a certain amount of ginsenoside (effective component ≥80%) and sweetener are weighed, and water in a corresponding proportion is added, and they are stirred to completely dissolve. Then 95vol% ethanol is added for dilution, and stirring is uniformly performed to obtain the formula systems of groups A to I. The states of different systems are observed.

[0081] Table 1

[0082]

[0083] As can be seen from Table 1, the ratio of water and ethanol should be ≥1:4, so that the ginsenoside and the sweetener can be completely dissolved, and the system is clear and free of precipitate.

[0084] Example 2

[0085] According to the formula in Table 2, modified gloss oil (95wt% gloss oil and 5wt% water-based acrylic resin) and ordinary gloss oil are added to groups A to I respectively, and the system states of different groups are observed.

[0086] Table 2

[0088] As can be seen from Table 2, groups D to G, that is, the mass ratio of water and ethanol should be ≤1:1, so that the modified gloss oil can be completely miscible. However, the ordinary gloss oil cannot be miscible in groups A to G.

[0089] Example 3

[0090] The influence of the total amount of ethanol and water and the mass ratio of the varnish on the coating effect of the tipping paper was studied according to the formulation in Table 3.

[0091] Table 3

[0093] As shown in Table 3, when the total amount of ethanol and water and the mass ratio of the varnish are between 1:1 and 1:2, the system has good coating effect.

[0094] In summary, in the present application, the mass ratio of water and ethanol is between 1:1 and 1:4, and the total amount of ethanol and water and the mass ratio of the varnish are between 1:1 and 1:2, which can ensure that the system has good solubility and coating effect at the same time.

[0095] Verification

[0096] 0.2 kg of ginsenoside powder (80%) and 0.2 kg of sweetener were dissolved in 7 kg of 95 vol% ethanol and 2 kg of water to obtain a ginsenoside solution, and then mixed with the improved varnish at a weight ratio of 1:1. The mixture was uniformly coated on the surface of the tipping paper in the last printing process to obtain a tipping paper containing ginsenosides and sweeteners.

[0097] The content of ginsenosides and sweeteners in the tipping paper was detected by the following method:

[0110] Standard solution:

[0111] The seven main standard substances in ginsenoside Rg1, Rg2, Rb1, Rb2, Re, Rc, Rd, etc. of ginsenoside were weighed, and five standard solutions with component contents of 2 μg / mL, 4 μg / mL, 10 μg / mL, 20 μg / mL, and 40 μg / mL were prepared. The standard detection linear coefficients of the seven standard substances were 1, 1, 0.99997, 0.99996, 1, 1, and 0.99998, respectively.

[0112] Pre-treatment of tipping paper sample:

[0113] 2 g of tipping paper sample was cut into 0.5 cm x 0.5 cm pieces, and was ultrasonically extracted with 70 vol% methanol solution for 30 min. After the extraction liquid was purified by a filter membrane, the content of ginsenoside in the tipping paper sample was determined by high performance liquid chromatography and external standard quantification.

[0114] The specific results are shown in Table 5 below:

[0120] The above tobacco tipping paper was used to prepare cigarettes to obtain test cigarette samples.

[0121] The ordinary tobacco tipping paper (without ginsenoside and sweetener) was used to prepare cigarettes to obtain control cigarette samples.

[0122] According to YC / T 138 "Tobacco and Tobacco Products Sensory Evaluation Method", 7 professionals were organized to compare the test cigarette samples and the control cigarette samples in terms of aroma, coordination, miscellaneous gas, stimulation, and aftertaste.

[0123] The results are shown in Table 6:

[0124] Table 6

[0125]

[0126] As can be seen from Table 5, the test cigarette sample has a higher score, and the main reason is that the cigarette tipping paper provided by the application has a light sweet taste and a comfortable taste because it contains ginsenosides and a sweetener, so it has a better smoking experience, and the main advantages are reflected in the aftertaste and irritation.
