A method for preparing a smoke extract of calligonum

Abstract

The application discloses a preparation method of a smoke use hackberry extract. The application drives multiple bubble generators arranged outside a knocking ball by an electromagnet. After the pretreated mixture is put into the equipment, the electromagnet applies repulsive force to the ferromagnetic material in the knocking ball to make it regularly knock the bottom of the mixture. Meanwhile, the bubble generators arranged outside the knocking ball are lemon acid and sodium carbonate particles. Under the mechanical impact caused by the knocking, the particles can effectively react with water to generate carbon dioxide microbubbles. The microbubbles can be uniformly dispersed in the mixture, so that the effective tumbling of the mixture is realized, and the low-efficiency problem of the traditional long-time static placement is avoided. On the other hand, the carbon dioxide microbubbles generated by the reaction provide an acidic environment to some extent. Compared with the boiling of the separately added acid in the later stage, the carbon dioxide microbubbles retain the heat-sensitive components, are more conducive to the destruction of cells, and accelerate the diffusion and release of effective components. Compared with the traditional static placement method, the application has obvious advantages in extraction speed and cost-effectiveness.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of preparation methods of tobacco Ziziphus jujuba Mill.var.spinosa, and more particularly to a preparation method of tobacco Ziziphus jujuba Mill.var.spinosa extract. BACKGROUND

[0002] Ziziphus jujuba Mill.var.spinosa is a kind of herbaceous plant, and its fruits or extracts are used in traditional medicine to treat various diseases. Ziziphus jujuba Mill.var.spinosa extract contains various chemical components that may be beneficial to the human body, such as polysaccharides, flavonoids, saponins and other bioactive substances. In the modern tobacco industry, manufacturers often explore new additives in order to increase the attractiveness of products and improve user experience. These additives can be used to improve the taste and aroma of tobacco, control the moisture of tobacco and reduce the generation of certain harmful substances. The bioactive components in Ziziphus jujuba Mill.var.spinosa extract may help neutralize free radicals generated during tobacco combustion, thereby possibly reducing some harmful health effects of smoking. At the same time, Ziziphus jujuba Mill.var.spinosa extract may have a positive impact on the processing technology of tobacco, such as improving the burning performance of tobacco leaves or stabilizing the storage of finished tobacco.

This standing method is very inefficient and takes a long time. During the long standing process, the effective components are difficult to fully release and diffuse, resulting in inefficient extraction. The mixed solution after standing needs to be subsequently treated by adding acid and boiling, which increases the time cost. At the same time, high temperature may damage some heat-sensitive components. The entire extraction method is inefficient, has high production cost, and cannot well meet the requirements of industrial production.

[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments, based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0046] Example 1:

[0047] Please refer to Figure 1 A preparation method of a tobacco hackberry extract, comprising the following steps:

[0048] S1: Mix the jujube with mannose, lactic acid, alcohol, propylene glycol and glycerol solution, crush the jujube at room temperature, and place the mixture in a softening and leaching device after mixing to a uniform state. The crushed jujube mixture is subjected to impact softening by the softening and leaching device, and bubbles are generated during the impact process to act on the jujube to improve the leaching efficiency;

[0049] S2: The mixture placed in the softening and leaching device is taken out and filtered to separate it into jujube crude extract and solid jujube residue;

[0050] S3: Concentrate the jujube crude extract using reduced pressure and vacuum technology, and recover alcohol at 39 degrees Celsius to obtain a first jujube liquid;

[0051] S4: Boil the remaining solid jujube residue with 3 times the amount of water for 0.5 hours, then concentrate the filtered liquid to obtain a second jujube liquid;

[0052] S5: Mix the concentrated first jujube liquid with the second jujube liquid in the appropriate proportion, and homogenize by stirring to obtain the final atomized extract;

[0053] S6: The final mixed atomized extract is converted into tiny droplets by atomization technology and uniformly applied to tobacco products to complete the application process of the extract.

[0054] Wherein, the electromagnet in the softening and leaching device drives multiple bubble generators arranged outside the knocking ball. After the pretreated mixture is placed in the device, the electromagnet applies a repulsive force to the ferromagnetic material inside the knocking ball, causing it to regularly knock the bottom of the mixture. At the same time, the bubble generators outside the knocking ball, which are lemon acid and sodium carbonate particles, can effectively react with water under the mechanical impact caused by knocking to generate carbon dioxide microbubbles. These microbubbles can be uniformly dispersed in the mixture, thereby achieving effective tumbling of the mixture and avoiding the low efficiency of traditional long-term static methods. On the other hand, the carbon dioxide microbubbles generated by the reaction can also provide an acidic environment to some extent. Compared with separately adding acid for boiling later, this method preserves heat-sensitive components and is more conducive to cell destruction and the diffusion and release of effective components, thus having obvious advantages in extraction speed and cost-effectiveness compared with traditional static methods.

[0055] The pretreatment operation steps of jujube in S1 include:

[0056] S11: Cleaning: First, wash the jujube thoroughly to remove dust and other impurities on the surface;

[0057] S12: Selection: After washing, manually select or use a machine to select jujubes, remove rotten fruits, branches and leaves, stones and other non-fruit components;

[0058] S13: Soaking: Soaking the cleaned calligonum in clean water to soften the fruit;

[0059] S14: Pitting: Done by hand or using a mechanical pitting device;

[0060] S15: Cutting or breaking: Cutting or breaking the pitted calligonum into small pieces.

[0061] Wherein, thoroughly cleaning the calligonum can remove potential contaminants such as dust, pesticide residues, and microorganisms from the surface of the fruit, ensuring the safety of subsequent processing and the purity of the extract, clean fruit has a positive impact on the quality of the final product, avoiding unnecessary impurities entering the extraction process, removing rotten fruit and non-fruit components, ensuring the consistency of raw materials, which is crucial for standardized production and the repeatability of the extraction process, removing undesirable fruit and impurities can interfere with the extraction process, reducing extraction efficiency and product quality, soaking can soften the fruit tissue, making it easier for effective components to be dissolved in the subsequent extraction process, softened fruit is easier to pit and cut or break, removing the core can reduce the content of non-target components in the extract, as the core may contain unwanted substances or difficult to handle substances, the core may be hard and difficult to break, removing the core can reduce wear and tear during mechanical processing and potential food safety risks, cutting or breaking the calligonum has a larger surface area, which is beneficial for solvents to contact more cell tissue, thereby improving the extraction rate of effective components, small pieces of calligonum can be more evenly mixed with solvents, accelerating the extraction process and shortening the extraction time.

[0062] The mass ratio of the plurality of components in S1 to calligonum is:

[0063] Mannitol: 0.15;

[0064] Lactic acid: 0.4;

[0065] Alcohol: 2.5;

[0066] Propylene glycol: 1.5;

[0067] Glycerol solution: 1.5.

[0068] Among them, mannose is a kind of osmotic protectant, which can protect the calligonum cell from being destroyed during the treatment process, which helps to maintain the integrity of the cell, thereby protecting the effective components in the cell, lactic acid can be used to adjust the pH value of the pretreatment solution, to create an ideal acidic environment for the extraction of effective components in calligonum, alcohol is a commonly used organic solvent, which can dissolve many water-insoluble or poorly soluble active ingredients, propylene glycol is a solvent, which can work together with alcohol to enhance the solvent capacity and help to extract the effective components in calligonum more effectively, glycerol has good moisturizing property, which can help to maintain the moisture of calligonum tissue and prevent drying and damage during pretreatment.

[0069] The mass ratio of these additives to calligonum is controlled within a certain range, which can optimize the pretreatment process, improve the efficiency and effect of the subsequent extraction step, and protect and extract the effective components in calligonum, ensuring the quality and stability of the extract.

[0070] Please refer to Figures 2-5 , the softening and precipitation device in S1 includes a placing plate 1, a rotating assembly 2 and a knocking ball 3, the top end of the placing plate 1 is fixedly connected with a stacking cylinder 12 and an L-shaped column 13, the stacking cylinder 12 is provided with a valve, and the bottom end of the L-shaped column 13 located at the top end of the stacking cylinder 12 is provided with a servo motor 14; the rotating assembly 2 includes an electromagnet 21, the output end of the servo motor 14 is fixedly connected with the top end of the electromagnet 21, and the bottom end of the electromagnet 21 is provided with a plurality of telescopic damping rods 22; the bottom end of the telescopic damping rod 22 is movably connected with the knocking ball 3.

[0071] The knocking ball 3 is a hollow spherical structure, and the inside of the hollow spherical structure is filled with ferromagnetic material, a plurality of evenly distributed slow-release holes are formed in the outer end of the knocking ball 3, and the slow-release holes are filled with bubble generating products, the bubble generating products are a mixture of citric acid and sodium bicarbonate, and are bonded together by mixing an adhesive, the molar mass ratio of citric acid and sodium bicarbonate is set to be between 1:1-2, and the plurality of telescopic damping rods 22 are distributed in a staggered manner.

[0072] Among them, the mixture of calligonum crushed at room temperature is placed in the softening and precipitation device, and after a period of standing, the solid part in the mixture is precipitated to the bottom of the softening and precipitation device under the action of gravity, at this time, the power switch of the electromagnet 21 can be started, so that the ferromagnetic material in the knocking ball 3 is added with a repulsive force by the electromagnet 21, so that the plurality of ferromagnetic materials synchronously drive the plurality of knocking balls 3 to knock the mixture precipitated at the bottom of the stacking cylinder 12, and on the basis of knocking, the power switch of the servo motor 14 can be started intermittently, so that the rotating assembly 2 can be driven to rotate intermittently, so that the plurality of knocking balls 3 contact the mixture precipitated at the bottom of the stacking cylinder 12 more uniformly and sufficiently.

[0073] By setting the outer surface of the knocking ball 3 to be provided with a plurality of evenly distributed slow-release holes filled with bubble generating substances, and the materials of the bubble generating substances are respectively set to be citric acid material and sodium bicarbonate material, both of which are edible materials. When the bubble generating substances react with water in the solution in the stacking cylinder 12, the knocking ball 3 quickly contacts the mixture precipitated at the bottom of the stacking cylinder 12, and the citric acid and sodium bicarbonate react with water, so that the generated carbon dioxide gas can turn over the mixture precipitated at the bottom of the stacking cylinder 12.

[0074] At the same time, the molar mass ratio of the citric acid material and the sodium bicarbonate material in the bubble generating substance is set to be between 1:1-2. Since citric acid is a ternary acid, it can release three hydrogen ions, and sodium bicarbonate is a weak base that can neutralize acid. One molecule of citric acid can react with three molecules of sodium bicarbonate. By setting the molar mass ratio, the citric acid will not be completely neutralized during the reaction, so that the pH value of the subsequent solution can be in the range of 5 to 6. This design not only turns over the mixture precipitated at the bottom of the stacking cylinder 12, but also makes the solution acidic after the reaction, which helps the precipitated mixture to better dissolve in the acidic environment. The cell wall and cell membrane can be broken down to release more cell contents, thereby increasing the extraction rate of effective ingredients. At the same time, some effective ingredients may be more stable under acidic conditions and are not easily oxidized or decomposed.

[0075] The filtered crude extract of the hackberry is subjected to vacuum and vacuum concentration, which is to reduce the boiling point of the liquid, so that alcohol and water can be evaporated at a lower temperature to protect heat-sensitive ingredients. The purpose of recovering alcohol at 39 degrees Celsius is to avoid damage to active ingredients caused by high temperature. Through vacuum and vacuum concentration, the first hackberry liquid obtained should be a relatively concentrated extract containing a high concentration of hackberry active ingredients.

[0076] The remaining solid hackberry residue is not immediately discarded, but is boiled again with 3 times the volume of water for 0.5 hours. The purpose is to further extract the active ingredients that may still exist in the residue. After boiling, the mixture is filtered again to separate more liquid second hackberry liquid. The filtered liquid also needs to be concentrated to reduce the volume and increase the concentration of active ingredients. It is worth noting that because the remaining solid hackberry residue still contains some liquid with a pH value between 5 and 6, the pH will change after adding several times the volume of water. At this time, a pH measuring instrument is needed to measure it and adjust the overall pH value to be between 5 and 6.

[0077] The preparation method of the knocking ball 3 includes the following steps:

[0078] S31: two symmetrical hollow hemispherical shells are processed and multiple grooves are reserved on the outer surface to form slow-release holes, and the two hollow hemispherical shells are detachably connected;

[0079] S32: the ferromagnetic material is filled between the two hollow hemispherical shells, and then the sealing is checked after the combination and fixation;

[0080] S33: after checking the good sealing, the bubble generator is filled into the slow-release holes on the outer surface of the hollow hemispherical shell.

[0081] In S2, the mixture can be separated by gravity filtration or centrifugal filtration.

[0082] The mold with a specific shape can be designed to accurately control the size, shape, and accuracy of the internal cavity and external groove of the knocking ball, and can be specifically matched with the shape and size of the knotted sediment, so as to realize higher knocking efficiency. At the same time, the consumed citric acid and sodium bicarbonate powder are supplemented to achieve the purpose of recycling.

[0083] Example 2:

[0084] The knotted willow is mixed with mannose, lactic acid, alcohol, propylene glycol and glycerol solution, and the mass ratio of multiple components to knotted willow is:

[0085] Mannose: 0.17;

[0086] Lactic acid: 0.5;

[0087] Alcohol: 2.7;

[0088] Propylene glycol: 1.7;

[0089] Glycerol solution: 1.7;

[0090] The knotted willow is crushed at room temperature, mixed to a uniform state, and placed in a softening and precipitation device. The crushed knotted willow mixture is impacted and softened by the softening and precipitation device, and bubbles are generated during the impact process to act on the knotted willow to improve the precipitation efficiency. The mixture placed in the softening and precipitation device is taken out and filtered to separate it into knotted willow crude extract and solid knotted willow residue. Vacuum and vacuum technology are applied to concentrate the knotted willow crude extract, and alcohol is recovered at 37°C. The first knotted willow liquid is obtained. The remaining solid knotted willow residue is boiled with 3.5 times the amount of water for 0.7h, and then the filtered liquid is concentrated to obtain the second knotted willow liquid. The concentrated first knotted willow liquid and the second knotted willow liquid are mixed and homogenized by stirring to obtain the final atomized extract. The final mixed atomized extract is converted into small droplets by atomization technology and uniformly applied to tobacco products to complete the application process of the extract.

[0091] Example 3:

[0092] The calligraphy is mixed with mannose, lactic acid, alcohol, propylene glycol and glycerol solution, and the mass ratio of the multiple components to the calligraphy is:

[0093] Mannose: 0.2;

[0094] Lactic acid: 0.55;

[0095] Alcohol: 2.9;

[0096] Propylene glycol: 2;

[0097] Glycerol solution: 2;

[0098] The calligraphy is crushed at room temperature, and after being mixed to a uniform state, it is placed in a softening and precipitation device. The crushed calligraphy mixture is subjected to impact softening by the softening and precipitation device, and bubbles are generated during the impact process to act on the calligraphy to improve the precipitation efficiency. The mixture placed in the softening and precipitation device is taken out and filtered to separate it into a calligraphy crude extract and a solid calligraphy residue. The calligraphy crude extract is concentrated by using reduced pressure and vacuum technology, and alcohol is recovered at 35 degrees Celsius. A first calligraphy liquid is obtained. The remaining solid calligraphy residue is boiled with 4 times the amount of water for 0.9 h, and then the filtered liquid is concentrated to obtain a second calligraphy liquid. The concentrated first calligraphy liquid and the second calligraphy liquid are mixed and homogenized by stirring to obtain a final atomized extraction liquid. The final mixed atomized extraction liquid is converted into small droplets by atomization technology and uniformly applied to tobacco products to complete the application process of the extraction liquid.
