Description
Technical Field
The invention belongs to the technical field of auxiliary materials for cigarettes, and particularly relates to a method for preparing cigarette filter stick aroma-enhancing pellets by using thin and short tobacco stems.
Background
Based on the idea of blending flavor without burning, the flavor substances which are compatible with the cigarette flavor or enhance the style characteristics are introduced into the cigarette smoke by utilizing the physical action of cigarette smoke elution, the aim of improving and enhancing the smoking quality of the cigarette can be achieved in a targeted way, and some achievements have been obtained by research on the aspect of natural plant materials and other novel materials. For example: patent CN 106723306A' A method for preparing cigarette filter stick additive by peppermint "discloses a method for preparing cigarette filter stick additive by peppermint. The sweet feeling and the fluid production feeling of the cigarette smoke can be increased, the irritation of the cigarette smoke is reduced, and the smoking quality of the cigarette is remarkably improved; patent 104687246B, Moringa oleifera porous particle, preparation method thereof and cigarette filter stick containing the same, discloses a Moringa oleifera porous particle which can make cigarette smoke exquisite and soft, reduce irritation, make cigarette fragrance clear and soft and improve the smoking quality of cigarettes; patent CN109730355A "a preparation method of flavor-enhancing granules for cigarette filter rods" discloses that porous granules are prepared by taking kaolin, volcanic rock, tourmaline and the like as raw materials, and then flavor substances are adsorbed on the porous granules, so that cigarette flavor can be enriched and aroma can be increased. However, new materials and methods are yet to be further explored.
The tobacco stems are the rough and hard veins of the tobacco leaves, account for about 25-30% of the tobacco leaves, and are used as tobacco production countries, and the tobacco stems produced by threshing and redrying in China are dozens of ten thousand tons each year. At present, tobacco stems are mainly applied to tobacco in a manner that the tobacco stems are added to a tobacco leaf group formula after being shredded to improve the filling value of tobacco shreds, reduce the tar content of smoke and be used for the production of reconstituted tobacco leaves, and most of the remaining tobacco stems are discarded. In the actual processing production of the tobacco stems, the tobacco stems are divided into thick long stems and thin short stems according to the shapes and sizes of the tobacco stems. Wherein the stem is the vein of the tobacco leaf and is closely connected with the tobacco leaf, so the chemical components and the sensory quality of the stem are closer to the tobacco leaf. Therefore, the development and application of the short tobacco stalks in the cigarettes are enhanced, and the utilization value and the utilization rate of the tobacco stalks can be greatly improved.
The tobacco flavor is one of the determining factors of the style of the cigarette products, and the development of novel tobacco flavor is urgent in the face of the requirements of large branding and specialization of the cigarette products. Wherein the development of microbial fermentation of flavors is an important approach to achieve this goal. Flavors prepared using fermentation techniques with natural raw materials as starting materials are referred to as natural equivalent flavors. The aroma-producing microorganism can generate huge high-activity enzyme systems such as saccharifying enzymes, cellulase and esterifying enzymes in the fermentation process, and can enable substrates to generate a series of reactions such as decomposition, degradation, oxidation, reduction, esterification and the like under the synergistic action of enzymatic action, chemical action and complex metabolism in the microorganism body to form complex low-molecular compounds which contain various aroma components such as alcohols, aldehydes, ketones, acids and the like. The spice with obvious air lattice characteristics can be prepared by fermenting specific aroma-producing microorganisms.
The ceramsite has the internal structural characteristics of fine honeycomb micropores, has the characteristics of large specific surface area, high strength, strong adsorbability, large biological load capacity and the like, and can be used as a water treatment filter material, an adsorbent, a culture medium for soilless culture in gardens and the like. The ceramsite is a good immobilization and adsorption carrier. At present, the research is mostly to apply the ceramsite to the sewage treatment. For example, patent CN1203009C "functionalized haydite carrier and immobilized microorganism sewage treatment technology" discloses a functionalized haydite carrier and immobilized microorganism sewage treatment technology thereof, the carrier has a rough surface and a macroporous structure, has the characteristics of light weight, washing resistance, stable chemical properties and the like, and can be used for immobilized microorganisms to form a fixed bed sewage treatment system; patent CN103482754B preparation method of shell ceramsite bio-carrier discloses a method for immobilizing microorganism by applying shell ceramsite, which can be used for solving the problems of insufficient alkalinity and the like in the current high ammonia nitrogen sewage treatment; patent CN108654207A "a preparation method of a multifunctional water treatment ceramsite filter material" discloses a preparation method of a multifunctional water treatment ceramsite filter material, which can not only purify sewage by adsorption and biodegradation, but also has self-cleaning capability under illumination, and is suitable for various forms of water pollution treatment. However, at present, no relevant report is found on the research of using the ceramsite as a carrier for fixing, producing and carrying aroma microorganisms and applying the ceramsite to cigarette filter sticks.
