Description

Technical Field

[0001] This invention relates to the tobacco industry, and in particular to a cigarette paper with functions that improve cigarette comfort, a method for preparing the same, and a cigarette. Background Technology

[0002] The aroma of cigarettes comes from tobacco, while flavorings and fragrances enhance and complement this aroma, improve the taste, increase the concentration of smoke, remove and mask unpleasant off-flavors, and reduce irritation. In recent years, with economic development and rising consumption levels and attitudes, smokers' demand for personalized tobacco products has become increasingly strong, leading to widespread attention on the adaptability and functionality of cigarette packaging materials. With the rapid application and development of many new materials and technologies in tobacco products, the "three papers and one stick" (cigarette paper, cigarette packaging material, and cigarette wrapper) have a significant impact on the appearance, sensory quality, and safety risks of cigarettes, making the specialization and differentiation of tobacco products increasingly apparent. However, research reports on cigarette paper-related products are relatively few, with research mainly focusing on plant fibers, air permeability, and ash packing. As living standards and public health awareness improve, market demand for functional cigarettes with reduced harm and tar content is gradually increasing.

[0003] Cigarette paper is a crucial material in cigarette production, and traditional cigarette paper is mainly composed of fibers, fillers, and combustion aids. Current research largely focuses on the effects of cigarette paper permeability, basis weight, tensile strength, and smoldering rate on the smoke composition of conventional cigarettes. Aroma is a key indicator of cigarette quality when describing sensory evaluation. Most conventional cigarette products generally suffer from a lack of aroma. The aroma dissipates quickly and is not persistent, resulting in dry, pungent, and insufficiently sweet smoke. These problems have become increasingly prominent with the application of various cigarette harm reduction and tar reduction technologies.

[0004] Therefore, addressing the issues of unsustainable aroma and poor sensory comfort in low-tar cigarettes, which weaken their distinctive characteristics and style, and meeting consumers' demands for cigarette quality, is of great significance for improving the smoking comfort of cigarettes. Summary of the Invention

[0005] In view of this, the present invention provides cigarette paper with the function of improving cigarette comfort, its preparation method and cigarette. The cigarette paper prepared by the present invention can not only make up for the lack of lasting aroma of traditional flavoring and additives, but also enhance the style differentiation and characteristics, improve the harmony with the natural aroma of tobacco, enhance the sensory comfort of cigarettes, and effectively reduce the amount of tar, nicotine and total particulate matter in the smoke.

[0065] Schisandra chinensis branches, the dried vine stems of the Schisandra chinensis (Turcz.) Baill., a plant of the Magnoliaceae family, are commonly known as "mountain pepper vines." They possess the effects of astringing the lungs and relieving cough, replenishing qi and promoting body fluids, nourishing and astringing essence, and calming the mind and nerves. Chaga mushroom, whose sclerotium is a medicinal fungus, also known as Inonotus obliquus, is a very precious medicinal fungus. Chaga mushroom has a wide range of biological activities, including antiviral, anti-inflammatory, antibacterial, anti-apoptotic, hair-growth, cough-relieving and expectorant, anti-aging, anti-fatigue, and liver-protective effects. Its effective chemical components, such as triterpenoids, steroids, polyphenols, aromatic compounds, and polysaccharides, have pharmacological effects such as inhibiting tumor cell proliferation, scavenging free radicals, lowering blood sugar, and regulating immune function. This invention combines ultrafine powder of Schisandra chinensis branches, specific tobacco oil, and birch polypore extract in a specific ratio and encapsulates them in molecular microcapsules. By fully utilizing the advantages of natural plant resources, this invention develops a unique flavoring ingredient that possesses both an elegant and distinctive aroma and a certain degree of harm reduction. This not only gives tobacco products a new flavor and new highlights, but also effectively mitigates the conflict between smoking and health. Its strong inimitable and original nature has significant economic value and social benefits in enhancing the market competitiveness of cigarettes.

[0066] Regarding step B) :

[0075] In this invention, the above-mentioned raw materials are mixed evenly, and then cigarette paper is obtained through a papermaking process. This invention does not impose any special limitations on the papermaking process; any conventional papermaking process in the field is acceptable.

[0076] The present invention also provides a cigarette paper with improved cigarette comfort function prepared by the preparation method described in the above technical solution.

[0077] The present invention also provides a cigarette, wherein the cigarette paper is the cigarette paper with the function of improving cigarette comfort described in the above technical solution.

[0078] This invention provides a method for preparing cigarette paper with improved cigarette comfort. The method involves using a mixture of ultrafine powdered Schisandra chinensis branches, specific tobacco oils, and birch polypore extract as the core material, and a polymer material as the wall material. Microcapsules containing the characteristic aroma ingredients are then prepared using a microencapsulation process. These microcapsules are then mixed with wood pulp fiber, hemp pulp fiber, and additives, and the resulting cigarette paper is produced using a papermaking process. In this process, Schisandra chinensis branches, a unique resource from Changbai Mountain, are used as the main raw material to address the issues of harsh, sweet, and irritating smoke caused by leaf blend formulations. Various tobacco oils are used as supplementary materials to enhance the natural tobacco aroma, while birch polypore extract harmonizes the aroma, improves the aftertaste, and adjusts the color of the cigarette paper. The microencapsulation technology produces a multifunctional cigarette paper that improves cigarette comfort. It can not only make up for the lack of lasting aroma in traditional flavoring and additives, but also enhance the style differentiation and characteristics, improve the harmony with the natural aroma of tobacco, improve the sensory comfort of cigarettes, and effectively reduce the amount of tar, nicotine and total particulate matter in the smoke.

[0079] Compared with the prior art, the present invention has the following beneficial effects:

[0080] 1. Adopting the concept of multifunctional cigarette paper, it promotes the forward development of cigarette flavoring and fragrance formulation, systematically optimizes and highlights the functional role of characteristic flavoring raw materials, improves cigarette comfort, and has simple operation procedures, low equipment process requirements, and high processing efficiency.

[0081] 2. By applying microencapsulation technology, the dispersion state of the encapsulated material can be changed, reducing the volatilization of specialty flavoring ingredients, ensuring the original aroma and active ingredients of natural plant flavorings, and improving the safety of tobacco products. At the same time, when the encapsulated material is released to the outside world, the permeation and diffusion of the capsule wall can effectively slow down the release rate or accelerate the release rate due to its forced rupture, thereby achieving the effect of controlled release.

[0082] 3. Implementing this invention can fully utilize the resources of Schisandra chinensis, saving Schisandra chinensis that can be used as traditional Chinese medicine and health food. At the same time, the raw material of Schisandra chinensis branches is pre-treated to obtain ultrafine powder of Schisandra chinensis branches, which has a more ideal effect of molecular microcapsule encapsulation. The sensory comfort and aroma quality are greatly improved, which can enrich the aroma of tobacco, harmonize with the original aroma of cigarette tobacco, and make the smoke delicate and soft. It can effectively improve the comfort of the mouth and throat, and give cigarettes characteristic aroma and taste. It has a significant effect on enhancing and supplementing the aroma of cigarettes.

[0144] As can be seen from the test results in Table 1, the functional cigarette paper prepared by encapsulating materials of a specific proportion and composition in molecular microcapsules according to Examples 1-5 of the present invention has a significantly higher overall score when applied to cigarettes. It has greatly improved sensory comfort and aroma quality, and can more effectively improve the aroma of cigarettes, increase the aroma of spiciness, sweetness and flue-cured tobacco, make the smoke delicate and mellow, effectively reduce throat and oral irritation, increase the aftertaste, improve the aftertaste, reduce irritation, and give cigarettes characteristic olfactory aroma and taste. It has little interference with the aroma of tobacco and has a significant effect on enhancing and supplementing the aroma of cigarettes.

[0145] 2. Mainstream smoke analysis of cigarettes made from functional cigarette paper.

[0146] Finished cigarettes were prepared according to the method described in Test 1 above and equilibrated in a constant temperature and humidity chamber (relative humidity 60±5%, temperature 22±2℃) for 48 hours. The results were analyzed according to the following standards: GB / T 23356-2009 "Determination of Carbon Monoxide in Gas Phase of Cigarette Smoke - Non-scattering Infrared Method"; GB / T 23203.1-2008 "Determination of Moisture in Total Particulate Matter of Cigarettes - Part 1: Gas Chromatography"; GB / T 23355-2009 "Determination of Nicotine in Total Particulate Matter of Cigarettes"; and GB / T 19609-2004 "Determination of Total Particulate Matter and Tar in Cigarettes Using a Smoking Machine for Routine Analysis". The results are shown in Table 2.

[0148]

[0149] As can be seen from the test results in Table 2, there is a certain regularity in the tar content, nicotine content, and total particulate matter in the smoke. The value of total particulate matter is directly proportional to the tar content and nicotine content. Compared with the finished cigarettes of Comparative Examples 1 to 4, the finished cigarettes made by adding functional cigarette paper with specific proportions and compositions in Examples 1 to 5 of the present invention burn more completely, with lower tar content, nicotine content, and total particulate matter values ​​in the mainstream smoke, and the smoke is softer and more delicate, with a more comfortable aftertaste and better sensory quality.
