Description

Technical Field

[0001] The invention belongs to the technical field of cigarette filter rods, and in particular relates to a filter rod capable of improving the taste of cigarettes and an application thereof. Background Art

[0002] As the cigarette market grows and the number of cigarette consumers increases, consumers have higher and higher requirements for the taste of cigarette products. In order to improve the smoking quality of cigarette products, cigarette manufacturers usually add some flavoring, smoke-generating, and antiseptic auxiliary materials during the production process of cigarettes. By adding the above auxiliary materials, the taste of cigarettes can be increased and the sensory quality of cigarettes can be improved.

[0003] CN115669999A discloses a method for preparing a sweet flavor for cigarette strands and a filter rod for cigarettes. The method for preparing the sweet flavor is as follows: (1) preparing a sweet component; (2) preparing a flavor component; (3) mixing the sweet component, the flavor component and the solvent, and filtering out the sediment. The method for preparing the filter rod is as follows: (1) adding and coating a plasticizer after the cigarette strands are subjected to an opening process; (2) feeding the cigarette strands into a molding cavity of a molding unit, and adding a sweet flavor; wherein the amount added to each mouth rod is 8-80 microliters; (3) wrapping the cigarette strands with molding paper to form the cigarette strands, controlling the molding temperature at 60-80°C, and then cutting the cigarette strands to obtain the cigarette strands. The filter rod flavor provided by the invention is slowly and continuously dissolved and released, which improves the comfort of smoking cigarettes, greatly improves the richness and naturalness of the smoking taste, and reduces the harm of cigarettes to human health.

[0004] CN117084448A discloses an agarwood cigarette and a manufacturing process thereof, the manufacturing process comprising: step (1), collecting agarwood leaves from an agarwood tree; naturally drying the collected agarwood leaves for 2 to 5 hours; then drying the agarwood leaves with hot air for 4 to 6 hours to make the moisture content of the agarwood leaves 10 to 15%; step (2), shredding the dried agarwood leaves to obtain agarwood shreds; then sorting the agarwood shreds to screen out leaf stems and debris; step (3), mixing 5 to 10 parts of the agarwood shreds in step (2) with 60 to 70 parts of shredded tobacco to obtain a first mixture; step (4), aging 1 to 2 parts of the fortified shredded tobacco; The biological agent is added to the first mixture in step (3), and after 6 hours of alcoholization, it is dried to make the moisture content of the first mixture 7-9%; step (5), 4-6 parts of tea leaves and 2-4 parts of licorice are dried by hot air, and then the dried tea leaves and licorice are ground into powder; step (6), the first mixture in step (4) is mixed with the tea powder and licorice powder in step (5) to obtain a second mixture, and the moisture content of agarwood shreds, tobacco shreds, tea powder and licorice powder is made consistent after 16-28 hours of moisture balance; step (7), the second mixture in step (6) is rolled into cigarettes using a conventional cigarette making process to obtain agarwood cigarettes. The agarwood cigarettes provided by the invention can enhance the effects of flavoring, aroma enhancement and smoke quality improvement of cigarettes, so that the smoke has a good sweet and smooth feeling and a full aroma.

[0005] Most of the existing technologies increase the aroma of cigarettes and improve the taste by adding flavors during the preparation of filter rods or tobacco. However, during the smoking process of cigarettes obtained by the above process, the tobacco is heated and the smoke has a high temperature, which will lead to the decomposition or volatilization of the flavors and the inability to obtain a distinct taste. Therefore, in order to better enhance the sensory experience of consumers, it is urgent to provide a cigarette product with better effects to meet the application needs. Summary of the invention

[0006] In view of the deficiencies of the prior art, the object of the present invention is to provide a filter rod capable of improving the taste of cigarettes and its application.

[0007] In order to achieve the purpose of the invention, the present invention adopts the following technical solutions:

[0008] In a first aspect, the present invention provides a filter rod capable of improving the taste of cigarettes, the filter rod capable of improving the taste of cigarettes comprising a filter element and a wrapping paper wrapped around the filter element, wherein the wrapping paper is an inner and outer two-layer tipping paper;

[0090] The raw materials for preparing the flavor layer are a combination of Peruvian extract, sweet orange extract, mint extract and green tea extract in a mass ratio of 3:1:1:1.

[0091] Test Example 1: Smoke Composition and Temperature Detection

[0092] The filter rods and tobacco shreds obtained in Examples 1-10 and Comparative Examples 1-2 that can improve the taste of cigarettes were used to prepare test cigarettes, and cigarettes made from common filter rods (acetate filter element, wrapped with a layer of common tipping paper, with specifications and dimensions consistent with those in Example 1) were used as control cigarettes. Before the test, the easy-tear tape of the outer tipping paper of the test cigarettes was torn off, and then the wavy tipping paper left after the tearing was folded up along the bottom line, so that the cigarette would form a petal shape with a certain angle to the tipping paper, and then the inlet temperature of the mainstream smoke of the test cigarettes after the above treatment was measured, and the above cigarettes were subjected to a draw resistance test.

[0093] Test method:

[0094] The draw resistance test refers to GB / T 22838.5-2009 Determination of physical properties of cigarettes and filter rods Part 5: Cigarette draw resistance and filter rod pressure drop.

[0095] The smoke temperature test adopts the thermocouple temperature measurement method, and simulates smoking according to the cigarette smoking model specified in the national standard YC / T29-1996. The thermocouple is fixed 1 mm from the center of the cigarette filter outlet. The thermocouple is connected to the temperature data acquisition system to measure the temperature of the smoke at the outlet of the cigarette filter tip during smoking.

[0096] The results are shown in Table 1.

[0097] Table 1

[0098]

[0099]

[0100] It can be seen from the data in Table 1 that after the filter rods prepared in Examples 1-3 of the present invention are used in cigarettes, the air holes can increase the inflow of external air, thereby making the draw resistance of the cigarette smaller and the inlet temperature more suitable.

[0101] It can be seen from Examples 9-10 that when the number of ventilation holes is small, the outside air cannot flow in smoothly, thereby increasing the draw resistance of the cigarette and raising the inlet temperature. However, when the number of ventilation holes is large, the above effects are not significantly affected, and when there are too many ventilation holes, the inner layer of tipping paper is more difficult to form.

[0102] It can be seen from Comparative Example 1 that when the inner layer of tipping paper has no air holes, the draw resistance of the cigarette is higher and the inlet temperature is not suitable.

[0103] Test Example 2 Sensory Quality

[0104] The sample preparation was the same as that in Test Example 1. The test cigarettes were subjected to sensory quality tests.

[0105] Test method: Refer to national standard GB 5606.4-2005 Cigarettes Part 4: Sensory technical requirements.

[0106] Test standards: The scoring range for aroma is 1-30 points, the scoring range for harmony is 1-10 points, the scoring range for foreign smell is 1-15 points, the scoring range for irritation is 1-20 points, the scoring range for aftertaste is 1-25 points, and the total score is 100 points.

[0107] The results are shown in Table 2.

[0108] Table 2

[0109]

[0110] It can be seen from Test Example 2 that after the filter rods prepared in Examples 1-3 of the present invention are used in cigarettes, the aroma, miscellaneous smell, harmony, irritation, taste and other aspects of the cigarettes are significantly improved.

[0111] As can be seen from Example 4, the aroma and taste of the cigarette can be increased by coating the flavor layer;

[0112] It can be seen from Examples 5-8 that the raw material selection of the flavor layer also has a great influence on the aroma and taste of the cigarette, and Peruvian extract, sweet orange extract, mint extract and green tea extract have a synergistic effect in improving the aroma and taste;

[0113] It can be seen from Examples 9 and 10 that when the number of air holes is small, the irritation and foreign smell of the cigarette will increase, while when the number of air holes is large, the irritation, i.e., foreign smell, will not be significantly reduced, and when there are too many air holes, the inner layer of the tipping paper will be more difficult to form;

[0114] From Comparative Example 1, it can be seen that when the inner tipping paper has no air holes, the cigarette has a higher irritation, but a poorer aroma and taste;

[0115] It can be seen from Comparative Example 2 that when there is only an inner layer of tipping paper, the components of the flavor layer will volatilize due to the lack of protection of the outer layer of tipping paper, thereby affecting the taste of the cigarette.

[0116] The applicant declares that the present invention uses the above-mentioned embodiments to illustrate a filter rod capable of increasing the taste of cigarettes and its application, but the present invention is not limited to the above-mentioned embodiments, that is, it does not mean that the present invention must rely on the above-mentioned embodiments to be implemented. Those skilled in the art should understand that any improvement of the present invention, equivalent replacement of various raw materials of the product of the present invention, addition of auxiliary components, selection of specific methods, etc., all fall within the protection scope and disclosure scope of the present invention.
