The cut stem, the special reconstructed cut stem is a reconstructed stem which is formed by extracting or removing the protein, polysaccharide and nitrate substance from the general tobacco stem silk, and then backfilling the tobacco stem silk with the predetermined aroma substance. Because the protein, polysaccharide, nitrate and other substances in the tobacco stems are heated in this temperature range of electric heating, the polysaccharide and protein will produce a scorching odor, which seriously affects the taste of the eater. In addition, the nitrate in the tobacco stems is decomposed by heat to produce nitrite (amine), which will cause harm to the human body, and fundamentally avoid the possibility of partial decomposition of nitrate to produce toxic gases. The aerosol generating carrier of the invention adopts a special reconstituted stem wire, which can well solve the above defects of the general tobacco stem silk during electric heating.

In the preparation method of the present invention, there is also a special step of removing or reducing protein: adding phosphoric acid in a mixture of solvent and tobacco stem, and then placing the mixture in an ultrahigh pressure vessel for a predetermined time, The mixture in the ultrahigh pressure vessel is simultaneously ultrasonicated for a predetermined period of time. The addition of phosphoric acid can acidify the protein, and the side chain reactive group of the protein binds to the phosphate group. By changing the electronegativity of the protein, the electrostatic repulsion between the protein molecules is increased, making them mutually repellent in the food system, and being easily dispersed to be water. The solvent is dissolved. In addition, in the state of ultra-high pressure (500 MPa), protein molecules can be polymerized into a polymer, and the molecular mass is increased, which is advantageous for interaction with a solvent such as water, and is advantageous for dissolution in a solvent. Simultaneous ultrasonic treatment can cause structural changes in protein molecules and improve the solubility of proteins in solvents such as water.

The technical solution of the present invention will be further described below in conjunction with the embodiments.

The reconstituted stem yarn further comprises an aerosol, and the specific aerosol comprises a polyol such as propylene glycol, glycerol, triethylene glycol, 1,3-butanediol; and a polyol oxime ester such as glyceryl octanoic acid Ester; polymer, such as polyethylene glycol 200, polyethylene glycol 400, etc., as well as long carbon chain monohydric alcohols, such as solanesol present in tobacco.

The aroma substances in the reconstituted stems include hair tobacco essential oil, volatile natural product essential oil, molecular distillation products of tobacco, such as benzyl alcohol, phenethyl alcohol, dihydrodamascone, β-ionone, dihydro kiwi Lactone, solanone, phytol, phytonone, acacia-based acetone, eugenol, eugenol, 3-oxo-α-ionol, etc. Fragrance components, such as geranylacetone, neophytadiene, cedartriene diol, methyl octadecyl carbonate and other tobacco distillation fractions below 300 ° C; molecular distillation of natural products; volatile food flavors (including various Flavoring components such as floral, fruity, and characteristic flavors; combinations of one or more of them.

The preparation method comprises the following steps:

1) Preparation of blank stems: preparing tobacco stems, and adopting extraction, solid-liquid separation and drying processes on the tobacco stems to remove or reduce protein, polysaccharide and nitrate substances in the tobacco stems, and complete Preparation of blank stems;

The extraction step specifically includes the following special steps of removing or reducing the protein: adding phosphoric acid in the mixture of the solvent and the tobacco stem, and then placing the mixture in an ultra-high pressure container (about 500 MPa) for a predetermined time. The mixture in the ultrahigh pressure vessel is simultaneously ultrasonically treated for the predetermined time.

2) Preparation of aerosol: According to the needs of the product, the suitable tobacco aroma components are properly mixed at an appropriate temperature, and then thoroughly mixed with the aerosol, and the obtained mixture is an aerosol.

3) Preparation of aerosol forming base material: the materials prepared in steps 1 and 2 are fed through a feeding device, and the material is sufficiently uniform through the extrusion homogenization process, and the homogenized smoke is formed into a base material, and the constant temperature and humidity are entered. After the process is water balanced, it is packaged for use.

In the process of tobacco growth, tobacco stems have their own special functions - to transport nutrients to the leaves, to promote the growth of tobacco, but also to grow themselves. Because of its transmission function, its internal structure is porous and multi-channel, so its special structure and effect are formed. This feature is beyond the characteristics of ordinary natural materials.

The invention fully utilizes the special structure and effect of the tobacco stem material, especially after the tobacco stem is extracted and processed, not only improves the space for effectively accommodating the material, but also avoids the inherent bad atmosphere released after being heated.

The products seen on the market are caused by the smoke matrix material. During the heating process, the paper is too heavy and the amount of smoke is insufficient. (Tobacco sheets are used as the smoke carrier. Because the sheet preparation is required by the strength, a certain amount of wood fiber must be added. When heated, the smell of baking paper is generated. In addition, due to the limitation of materials, it is impossible to add more aerosols, and the proportion of aerosols is up to 30%, so the amount of smoke is limited);

CN106723282A describes the use of porous tobacco stems to absorb the atomizing agent, thereby increasing the amount of smoke in the tobacco product, but does not consider the negative effect of the stalk ribbon on the smoking taste of the tobacco product, nor does it involve electric heating without burning. Case.

Generally, heating a non-combustible tobacco product requires heating the tobacco substrate to above 200 ° C to produce a nicotine-containing aerosol. As the smoker continues to smoke, the tobacco matrix is continuously heated, and the protein and sugar contained in the heated body are coked as the temperature rises, giving an unpleasant scent.

The invention aims to provide a special reconstituted cut stem by applying the original stem material to the deficiencies of heating when not burning, and after extracting or removing the protein, polysaccharide and nitrate substance in the general tobacco stem silk, Reconstituted stems formed by backfilling the tobacco stems with a predetermined aroma substance. Because the protein, polysaccharide, nitrate and other substances in the tobacco stems are heated in this temperature range of electric heating, the polysaccharide and protein will produce a scorching odor, which seriously affects the taste of the eater. In addition, the nitrate in the tobacco stems is decomposed by heat to produce nitrite (amine), which will cause harm to the human body, and fundamentally avoid the possibility of partial decomposition of nitrate to produce toxic gases. The cigarette aerosol generating carrier of the invention adopts a special reconstituted cut stem, which can well solve the above defects of the general tobacco stem silk during electric heating.

Tobacco stems include raw stems, stems, granules, and stalk powder, whether or not they are puffed, are within our range. In view of the ease of processing and use, in the examples, the form of the cut stem is preferred as an example. Including the following steps:

2. Preparation of aerosol: According to the needs of the product, the suitable tobacco aroma components are properly mixed at an appropriate temperature, and then thoroughly mixed with the aerosol, and the obtained mixture is an aerosol.

3. Preparation of the aerosol forming base material: the materials prepared in the steps 1 and 2 are fed through a feeding device, and the material is sufficiently uniform by the extrusion homogenization process. The homogenized smoke production forms a base material, and after water balance in a constant temperature and humidity process, it is packaged for use.

The above-mentioned extracted stems are compared with the original stems:

After extraction, more than 90% of the water-soluble matter in the stalk is removed, and its own weight is reduced by half. The removal of water-soluble substances not only increases the space for the material to be absorbed by the stalk, but more importantly, it removes the chemical components inherent in the stalk that produce bad atmosphere at high temperatures, which is a clear advantage; the eliminated protein can avoid smog The base is heated to produce a burning feather;

After extraction, the elimination of most of the sugar can also avoid the scorching atmosphere when heating (including polysaccharide starch, pectin generated when the pectin is heated);

After extraction, the basic elimination of nitrate greatly reduces the possibility of nitrate decomposition by thermal decomposition of nitrite (amine) and the health of smokers; in addition, it also fundamentally avoids the thermal decomposition of some nitrates. The possibility of NO2 toxic gases.
