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 sensory quality 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. At present, the taste and flavor of most cigarettes mainly come from the smoke released when tobacco is burned. Therefore, cigarette manufacturers usually add some auxiliary materials such as flavoring and taste enhancement to the tobacco 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] CN118266609A discloses a method for improving the sensory quality of sweet, mellow and sweet tobacco leaves, using tobacco leaves of relatively poor quality in the sweet, mellow and sweet tobacco producing area as raw materials, developing tobacco extracts through biotechnology and multi-stage separation technology, and preparing functional enhanced flavor L and style enhanced flavor X respectively through flavoring means, and in the process of making shreds, the functional enhanced flavor L is applied to shredded tobacco at a ratio of 0.05-0.2%, and the style enhanced flavor X is applied to shredded tobacco at a ratio of 0.005-0.02% to enhance the sensory quality of sweet, mellow and sweet tobacco leaves. In addition, by improving the sensory quality and taste of tobacco leaves, the satisfaction of smokers can be increased, and their recognition and loyalty to the product can be improved.

[0004] CN109619642A discloses a patent application for a tobacco extract for tobacco flavoring and a preparation method thereof. The tobacco extract is prepared by mixing the chlorogenic acid extract of Eucommia ulmoides with tobacco dust, fermenting with yeast and extracting. The specific preparation includes the steps of mixing tobacco dust with chlorogenic acid, fermenting with yeast, preparing the extract and the like. The tobacco extract can be used for tobacco and is used at a mass ratio of 0.1 to 0.5‰ of tobacco shreds. When used, the tobacco extract is dissolved in ethanol and evenly sprayed on the surface of the tobacco shreds. The tobacco extract preparation method provided in the application can, on the one hand, make full use of existing tobacco waste (tobacco dust), and on the other hand, the prepared tobacco extract exhibits a more obvious flavoring effect and is rich in aroma substances. In addition, the relevant preparation process is green, safe and has good repeatability.

[0005] The above-mentioned prior art all adds flavoring ingredients to tobacco shreds to increase the aroma of cigarettes and improve the taste. However, after the flavoring ingredients are attached to the surface of tobacco shreds, they are directly involved in combustion, and the aroma components are lost more at high temperatures, resulting in a less significant flavoring effect. Therefore, in order to better enhance the sensory experience of consumers, it is urgent to provide a cigarette product with a more significant flavoring effect 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 and application thereof that can improve the sensory quality of cigarettes.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] (1) The filter rod provided by the present invention can improve the sensory quality of cigarettes. When in use, the silk thread of the outer tipping paper can be torn off. Since the surface of the inner tipping paper is provided with air holes, the outside air can flow into the filter rod, which can not only reduce the inhalation resistance of the cigarette and adjust the inlet temperature, but also bring the aroma of the tobacco sheet layer into the filter rod, thereby improving the taste of the cigarette.

[0043] (2) The tobacco sheet layer in the filter rod provided by the present invention can release the aroma of grass and wood when heated by adding the first plant essential oil, which can be combined with the animal aroma of the second plant essential oil in the filter element to more significantly improve the taste of the cigarette.

[0112] Test Example 1: Smoke Composition and Temperature Detection

[0113] The filter rods and shredded tobacco obtained in Examples 1-14 and Comparative Examples 1-3 that can improve the sensory quality of cigarettes were used to prepare test cigarettes, and cigarettes made of ordinary filter rods (acetate filter element, wrapped with a layer of ordinary tipping paper) were used as control cigarettes. During the test, the easy-tear tape of the outer tipping paper of the test cigarettes was torn off, 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.

[0114] Test method:

[0115] 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.

[0116] 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.

[0117] The results are shown in Table 1.

[0118] Table 1

[0119]

[0120]

[0121] 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, since the tear strip of the outer tipping paper is removed, the tobacco sheet layer contains a pore-forming agent, and the inner tipping paper has air holes on its surface, which can increase the inflow of external air, thereby making the draw resistance of the cigarette smaller and the inlet temperature more suitable.

[0122] It can be seen from Examples 4-5 that when the outer tipping paper is not provided with an easy-tear tape or the inner tipping paper is not provided with air holes, the outside air cannot flow in smoothly, thereby increasing the draw resistance of the cigarette and raising the inlet temperature.

[0123] Test Example 2 Sensory Quality

[0124] The sample preparation was the same as that in Test Example 1. The test cigarettes were subjected to sensory quality tests.

[0125] Test method: Refer to national standard GB 5606.4-2005 Cigarettes Part 4: Sensory technical requirements.

[0126] 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.

[0127] The results are shown in Table 2.

[0128] Table 2

[0129]

[0130]

[0131] 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.

[0132] It can be seen from Example 4 that when the outer tipping paper has no tear strip, the outside air cannot flow into the filter tip, and the aroma components in the tobacco sheet cannot enter the filter rod well, affecting the taste of the cigarette;

[0133] It can be seen from Example 5 that when the inner layer of tipping paper has no air holes, the aroma components in the tobacco sheet cannot enter the filter rod well, affecting the taste of the cigarette;

[0134] It can be seen from Examples 6-12 that the selection of the components of the first plant essential oil and the second plant essential oil also has a great influence on the aroma and taste of the cigarette, and the combination of peppermint oil, prickly ash oil, camphor oil and pine essential oil can form a more significant herbal aroma, and the combination of Peruvian balm oil, lemon oil and sweet orange oil can form a more significant animal aroma;

[0135] It can be seen from Examples 13 and 14 that when the components of the first plant essential oil and the second plant essential oil are directly mixed, antagonism will occur between the essential oils, thereby affecting the taste and aroma of the cigarette;

[0136] It can be seen from Comparative Examples 1-3 that the herbal aroma of the first plant essential oil and the animal aroma of the second plant essential oil can significantly improve the taste of cigarettes only after being mixed, while when only one of the aromas is present, the sensory enhancement effect of cigarettes is not obvious.
