Description

[Technical Field]

[0001] This invention belongs to the field of tobacco processing technology. More specifically, this invention relates to a tobacco flavor capsule, and also to a method for preparing the tobacco flavor capsule. [Background Technology]

[0002] Cigarette flavor capsules, a relatively new cigarette product, offer benefits such as moisture retention, flavor enhancement, and tar reduction. Due to their diverse flavors and innovative features, they have been widely popular with consumers since their introduction and have become a significant innovation point in the daily chemical, food, and tobacco industries. They are made by blending various flavorings with specific solvents to create a core liquid with a particular aroma, which is then combined with a wall material possessing certain mechanical properties, allowing for extensive innovation.

[0003] In recent years, with the rapid development of capsule cigarettes in domestic and international markets, tobacco companies have continuously increased their research and attention to capsule cigarettes. Currently, most research on capsule cigarettes focuses on the flavor of the capsule core material, the additives and performance of the wall material, and the application of capsules in cigarettes. At present, the application of capsules in cigarettes is mostly concentrated on placing the capsule in the filter rod, squeezing it to pop it, and then smoking it. In order to improve the ease of use of capsule cigarettes, enrich the application of capsules in cigarettes, and enhance the smoking experience for consumers, this invention places the capsule in the tobacco shreds, which can be directly burst when lit.

[0004] Based on a summary of existing technologies, the inventors have completed this invention through extensive experimental research and analysis. [Summary of the Invention]

[0005] [Technical problem to be solved]

[0006] The purpose of this invention is to provide a tobacco flavor capsule.

[0007] Another object of the present invention is to provide a method for preparing the aforementioned tobacco flavor capsules.

[0008] [Technical Solution]

[0009] The present invention is achieved through the following technical solution.

[0010] This invention relates to a tobacco flavor capsule.

[0011] The cigarette capsule is composed of a core liquid and an outer rubber layer encapsulating the core liquid in a weight ratio of 1:2 to 4, with 2 to 4 small capsules dispersed in the core liquid; the core liquid is a mixture of 1 to 3 parts by weight of flavoring and 400 to 800 parts by weight of vegetable oil; the outer rubber layer is composed of 2 to 5 parts by weight of starch, 0.1 to 0.8 parts by weight of cellulose, 5 to 20 parts by weight of plant gum and 10 to 25 parts by weight of distilled water;

[0012] The diameter of the cigarette-grade burst beads is 3.5–4.2 mm, and the diameter of the small burst beads is 0.1–0.3 mm. Their chemical composition is the same as that of the cigarette-grade burst beads.

[0013] According to a preferred embodiment of the present invention, the flavoring is one or more flavorings selected from mint, blueberry, watermelon or cantaloupe flavorings.

[0014] According to another preferred embodiment of the present invention, the vegetable oil is one or more vegetable oils selected from olive oil, rapeseed oil, flaxseed oil or soybean oil.

[0015] According to another preferred embodiment of the present invention, the starch is one or more starches selected from corn starch, soybean starch, wheat starch or potato starch.

[0016] According to another preferred embodiment of the present invention, the cellulose is one or more celluloses selected from hydroxymethylcellulose, methylcellulose or hydroxypropylmethylcellulose.

[0017] According to another preferred embodiment of the present invention, the plant gum is one or more plant gums selected from carrageenan, gellan gum, guar gum or gelatin.

[0018] The present invention also relates to a method for preparing tobacco flavoring beads.

[0019] The preparation steps of the preparation method are as follows:

[0020] A. Preparation of core fluid

[0021] One to three parts by weight of a flavoring selected from peppermint, blueberry, watermelon, or cantaloupe flavorings are fully dissolved in 400 to 800 parts by weight of a vegetable oil selected from olive oil, rapeseed oil, flaxseed oil, or soybean oil to obtain the core liquid.

[0022] B. Preparation of outer rubber material

[0023] 2-5 parts by weight of starch selected from corn starch, soybean starch, wheat starch or potato starch, 0.1-0.8 parts by weight of cellulose selected from hydroxymethylcellulose, methylcellulose or hydroxypropyl methylcellulose, and 5-20 parts by weight of plant gum selected from carrageenan, gellan gum, guar gum or gelatin are dissolved in 10-25 parts by weight of distilled water. The mixture is heated in a water bath at 70-80°C with stirring until it is completely dissolved. After standing, the mixture is cooled to 40-50°C to remove air bubbles. The outer rubber material is then collected by passing it through an 80-100 mesh sieve.

[0024] C. Drip

[0025] Using a pelletizing machine, the core liquid obtained in step A and the outer rubber material obtained in step B are added to the core liquid container and the outer rubber material container of the pelletizing machine, respectively. Under the conditions of pressure -0.1 to 0.1 MPa and magnetic stirring speed of 300 to 800 rpm, the single-channel four-layer dripper of the pelletizing machine drips the outer rubber material into the cooling oil from the outside to the inside in the first layer at a flow rate of 25 to 30 ml / min, and the core liquid is dripped into the second layer at a flow rate of 15 to 25 ml / min. They form a kind of smoke-like bursting bead in the cooling oil. The outer rubber material is dripped into the third layer at a flow rate of 35 to 40 ml / min, and the core liquid is dripped into the fourth layer at a flow rate of 30 to 35 ml / min. They form a kind of small bursting bead in the outer capsule core liquid. The smoke-like bursting bead and the small bursting bead are cooled at a temperature of 15 to 18°C ​​for 1.0 to 2.0 min, thus obtaining a kind of smoke-like bursting bead containing 2 to 4 small bursting beads per bead.

[0026] D. Post-processing

[0027] The tobacco burst beads obtained in step C are washed 3 to 5 times with ethanol solvent at a concentration of 70 to 80% by volume, and then dried, according to a ratio of 1:30 to 50 by weight of tobacco burst beads to ethanol solvent at a concentration of 70 to 80% by volume.

[0028] According to a preferred embodiment of the present invention, in step B, the equipment used for cooling is a compression refrigeration machine, a water cooling machine, a chiller, or an air compressor.

[0029] According to another preferred embodiment of the present invention, in step C, the pellet mill is a single-channel four-layer pellet mill.

[0030] According to another preferred embodiment of the present invention, in step C, the equipment used for drying is a microwave drying and sterilization machine, a honeycomb ceramic dryer, a hollow paddle dryer, or a rotary drum drying device.

[0031] The invention will now be described in more detail.

[0032] This invention relates to a tobacco flavor capsule.

[0033] The cigarette capsule is composed of a core liquid and an outer rubber layer that encapsulates the core liquid in a weight ratio of 1:2 to 4, with 2 to 4 small capsules dispersed in the core liquid.

[0034] According to the present invention, the basic function of the small burst beads in the core liquid in the cigarette burst beads of the present invention is to make the aroma substances diffuse over a wider area, disperse the aroma evenly, and improve the experience.

[0035] The CQS-IV cigarette flavoring bead quality testing system was used to test the cigarette flavoring bead, and the diameter of the flavoring bead was 3.5-4.2 mm, while the diameter of the small flavoring bead was 0.1-0.3 mm.

[0036] The chemical composition of the small burst beads is the same as that of the cigarette burst beads.

[0037] In this invention, the weight ratio of the core liquid to the outer rubber layer is 1:2 to 4.

[0038] The core liquid is a mixture of 1-3 parts by weight of flavoring and 400-800 parts by weight of vegetable oil. The basic function of the flavoring in the cigarette flavoring core liquid is to enrich the tobacco aroma, improve the quality of the tobacco leaves, and enhance the smoking experience of the cigarette. The flavoring used in this invention is one or more flavorings selected from mint, blueberry, watermelon, or cantaloupe flavorings. These are all commercially available products, such as those sold by Qingdao Baixu Food Co., Ltd. under the trade names of mint oil flavoring, blueberry flavoring, watermelon flavoring, and cantaloupe flavoring. The main function of the vegetable oil in the cigarette flavoring core liquid is as a good solvent for flavoring the tobacco flavoring, and it also has an oxygen-isolating effect, while preventing the aroma components in the core liquid from evaporating. The vegetable oil used in this invention is one or more vegetable oils selected from olive oil, rapeseed oil, flaxseed oil or soybean oil. These are all products currently sold on the market, such as olive oil sold by Wuhan Kanos Technology Co., Ltd. under the trade name olive oil, rapeseed oil sold by Quanzhou Wufou Trading Co., Ltd. under the trade name Fulimen Jiaxiang Fragrance Pressed Rapeseed Oil, flaxseed oil sold by Shanghai Yingting Industrial Co., Ltd. under the trade name flaxseed oil, and soybean oil sold by Gaoan Qinghe Oil Co., Ltd. under the trade name non-GMO soybean oil.

[0039] According to the present invention, when the content of vegetable oil is within the specified range, if the content of flavoring is less than 1 part by weight, the aroma concentration of the core liquid is too low, reducing the smoking experience; if the content of flavoring is higher than 3 parts by weight, the aroma concentration of the core liquid is too high, which is not conducive to the smoking effect of the cigarette capsule of the present invention; therefore, a flavoring content of 1 to 3 parts by weight is suitable. When the content of flavoring is within the specified range, if the content of vegetable oil is less than 400 parts by weight, the flavoring is not easily dissolved and the concentration is too high; if the content of vegetable oil is higher than 800 parts by weight, the flavoring is excessively diluted and the concentration is too low, significantly reducing the use effect of the cigarette capsule of the present invention; therefore, a vegetable oil content of 400 to 800 parts by weight is appropriate.

[0040] According to the present invention, the outer rubber layer is composed of 2 to 5 parts by weight of starch, 0.1 to 0.8 parts by weight of cellulose, 5 to 20 parts by weight of plant gum and 10 to 25 parts by weight of distilled water.

[0041] In this invention, the basic function of starch in the tobacco menthol capsule coating is to increase the viscosity and elasticity of the mixed sol. The starch used in this invention is one or more starches selected from corn starch, soybean starch, wheat starch, or potato starch, all of which are currently commercially available products. For example, corn starch sold by Shandong Xinhongwang New Material Co., Ltd. under the trade name "Edible Corn Starch," soybean starch sold by Shandong Runfeng Yujing Food Co., Ltd. under the trade name "Soybean Starch," wheat starch sold by Shandong Xinhongwang New Material Co., Ltd. under the trade name "Wheat Starch," and potato starch sold by Shandong Kunhong Chemical Technology Co., Ltd. under the trade name "Cassava Starch."

[0042] Cellulose possesses excellent wettability, dispersibility, adhesiveness, thickening, emulsifying, and film-forming properties. Its main role in cigarette menthol capsules lies in its numerous reactive functional groups, exhibiting excellent synergistic effects with other components of the capsule material in this invention. The cellulose used in this invention is one or more celluloses selected from hydroxymethylcellulose, methylcellulose, or hydroxypropyl methylcellulose, all of which are commercially available products, such as those sold by Langfang Feitai New Material Technology Co., Ltd. under the trade names hydroxymethylcellulose, methylcellulose, and hydroxypropyl methylcellulose.

[0043] The basic functions of plant gums in cigarette menthol capsules are thickener, stabilizer, and emulsifier. The plant gums used in this invention are one or more selected from carrageenan, gellan gum, guar gum, or gelatin. These are all commercially available products, such as carrageenan sold by Qingdao Jinqingda Co., Ltd. under the trade name K-type carrageenan, gellan gum sold by Shandong Kangle Biotechnology Co., Ltd. under the trade name gellan gum, guar gum sold by Henan Rude Food Ingredients Co., Ltd. under the trade name Liuhe guar gum, and gelatin sold by Guangzhou Huayu Biotechnology Co., Ltd. under the trade name gelatin.

[0044] In this step, when the contents of cellulose, plant gum, and distilled water are within the specified range, if the starch content is less than 2 parts by weight, the viscosity and elasticity of the prepared sol will be low; if the starch content is more than 5 parts by weight, the prepared sol will be too stiff, which is not conducive to subsequent processing. Therefore, a starch content of 2-5 parts by weight is reasonable. When the contents of starch, plant gum, and distilled water are within the specified range, if the cellulose content is less than 0.1 parts by weight, the viscosity and film-forming properties of the prepared sol will be poor; if the cellulose content is more than 0.8 parts by weight, the viscosity of the prepared sol will be high, and the cellulose will not be uniformly dispersed in the solution. Therefore, a cellulose content of 0.1-0.8 parts by weight is appropriate. When the contents of starch, cellulose, and distilled water are within the specified range, if the plant gum content is less than 5 parts by weight, the viscosity and emulsifying properties of the prepared sol will be poor; if the plant gum content is more than 20 parts by weight, the prepared sol will be too viscous and cannot be completely emulsified. Therefore, a plant gum content of 5-20 parts by weight is suitable.

[0045] The present invention also relates to a method for preparing tobacco flavoring beads.

[0046] The preparation steps of the preparation method are as follows:

[0047] A. Preparation of core fluid

[0048] One to three parts by weight of a flavoring selected from peppermint, blueberry, watermelon, or cantaloupe flavorings are fully dissolved in 400 to 800 parts by weight of a vegetable oil selected from olive oil, rapeseed oil, flaxseed oil, or soybean oil to obtain the core liquid.

[0049] B. Preparation of outer rubber material

[0050] 2-5 parts by weight of starch selected from corn starch, soybean starch, wheat starch or potato starch, 0.1-0.8 parts by weight of cellulose selected from hydroxymethylcellulose, methylcellulose or hydroxypropyl methylcellulose, and 5-20 parts by weight of plant gum selected from carrageenan, gellan gum, guar gum or gelatin are dissolved in 10-25 parts by weight of distilled water. The mixture is heated in a water bath at 70-80°C with stirring until it is completely dissolved. After standing, the mixture is cooled to 40-50°C to remove air bubbles. The outer rubber material is then collected by passing it through an 80-100 mesh sieve.

[0051] In this step, starch, cellulose, and plant gums are dissolved in distilled water at a temperature of 70–80°C with stirring. If the dissolution temperature is below 70°C, the mixed sol will not be uniform; if the dissolution temperature is above 80°C, it will cause the mixed sol to burn or release volatiles. Therefore, a dissolution temperature of 70–80°C is preferable.

[0052] In this step, the basic purpose of settling is to allow the temperature of the sol to drop to a suitable level. The subsequent cooling of the sol is to prevent it from solidifying and forming a complete gel. The equipment used for cooling includes compressors, water coolers, chillers, or air compressors. These are all commercially available products. For example, compressors sold by Zhejiang Lanqi Refrigeration Equipment Co., Ltd. under the trade name "Semi-hermetic compressor condenser"; water coolers sold by Zhejiang Wanpeng Temperature Control Technology Co., Ltd. under the trade name "Water Circulation Water Cooler"; chillers sold by Shanghai Kangcai Refrigeration Equipment Co., Ltd. under the trade name "-35℃ Air-Cooled Low-Temperature Industrial Chiller"; and air compressors sold by Qingdao Haigeer Compressor Co., Ltd. under the trade name "Low-Pressure Air Compressor".

[0053] C. Drip

[0054] Using a pelletizing machine, the core liquid obtained in step A and the outer rubber material obtained in step B are added to the core liquid container and the outer rubber material container of the pelletizing machine, respectively. Under the conditions of a pressure of -0.1 to 0.1 MPa and a magnetic stirring speed of 300 to 800 rpm, the single-channel four-layer dripper of the pelletizing machine drips the outer rubber material into the cooling oil from the outside to the inside in the first layer at a flow rate of 25 to 30 ml / min, and drips the core liquid from the second layer at a flow rate of 15 to 25 ml / min. They form a kind of smoke-like bursting bead in the cooling oil, and the third layer drips the outer rubber material into the cooling oil. The outer rubber material is dripped into the fourth layer at a flow rate of 35-40 ml / min, and the core liquid is dripped into the fifth layer at a flow rate of 30-35 ml / min. They form a small bursting bead in the core liquid of the outer capsule. The cigarette bursting bead and the small bursting bead are cooled at a temperature of 15-18°C for 1.0-2.0 min. The difference in dripping speed between the inner and outer double-layer droppers and the rubber liquid and flavoring allows the core liquid and the outer rubber material to form bursting beads of different particle sizes under pressure and stirring. Thus, a cigarette bursting bead containing 2-4 small bursting beads is obtained.

[0055] In this invention, the formed bursting beads are dropped into a dimethyl silicone oil coolant and cooled at 15–18°C for 1.0–2.0 min. Within this cooling time range, if the cooling temperature is below 15°C, the bursting beads are prone to freezing and cracking; if the cooling temperature is above 18°C, the bursting beads are prone to softening. Therefore, a cooling temperature of 15–18°C is suitable. Within this cooling temperature range, if the cooling time is less than 1.0 min, the cooling is insufficient, and the bursting beads are prone to rupture; if the cooling time is longer than 2.0 min, the bursting beads are prone to freezing and cracking. Therefore, a cooling time of 1.0–2.0 min is appropriate.

[0056] The pellet milling machine used in this invention is a single-channel, four-layer pellet milling machine, which is a product of Kunming Xubang Machinery Co., Ltd. under the product list of single-channel, four-layer pellet milling machines.

[0057] D. Post-processing

[0058] The tobacco burst beads obtained in step C are washed 3 to 5 times with ethanol solvent at a concentration of 70 to 80% by volume, and then dried, according to a ratio of 1:30 to 50 by weight of tobacco burst beads to ethanol solvent at a concentration of 70 to 80% by volume.

[0059] In this invention, the purpose of washing with ethanol solvent is to remove the dimethyl silicone oil coolant remaining on the surface of the cigarette capsule.

[0060] During washing, if the ratio of the cigarette-flashing beads to the ethanol solvent is greater than 1:30, the solvent concentration is less than 70%, and the number of washes is less than 3, the dimethyl silicone oil coolant remaining on the surface of the cigarette-flashing beads cannot be completely washed away; if the ratio of the cigarette-flashing beads to the ethanol solvent is less than 1:50, the solvent concentration is greater than 80%, and the number of washes is more than 5, the volatile substances in the cigarette-flashing beads are easily washed away.

[0061] The drying equipment used in this invention includes microwave drying and sterilization machines, honeycomb ceramic dryers, hollow paddle dryers, and rotary drum drying equipment. These are all products currently sold on the market. For example, microwave drying and sterilization machines are sold by Guangzhou Diwei Industrial Microwave Equipment Co., Ltd. under the trade name "Microwave Drying and Sterilization Machine"; honeycomb ceramic dryers are sold by Shandong Liwei Microwave Equipment Co., Ltd. under the trade name "Fully Automatic Honeycomb Ceramic Drying Equipment"; hollow paddle dryers are sold by Changzhou Pingge Drying Equipment Co., Ltd. under the trade name "Hollow Paddle Dryer"; and rotary drum drying equipment is sold by Huai'ren Jiawang Machinery Co., Ltd. under the trade name "Capsule Drying Rotary Drum".

[0062] Washed tobacco capsules are dried using a microwave dryer, honeycomb ceramic dryer, hollow paddle dryer, or rotary drum dryer until the water content is less than 2% by weight.

[0063] For details on the placement of the tobacco flavor capsules in this invention directly added to the tobacco, please refer to the appendix. Figure 1 .

[0064] According to GB 5606.4-2005 Cigarettes Part 4: Sensory Technical Requirements, a tasting panel of 7 evaluators conducted a comparative tasting of cigarettes with the flavor capsules of this invention added and those with single flavor capsules added to filter rods in existing commercial products as control samples. The tasting results are shown in the detailed implementation section.

[0065] [Beneficial Effects]

[0066] The beneficial effects of this invention are as follows: The flavor capsules of this invention are directly added to the tobacco shreds. Combustion causes the capsules to burst, making the process simple. Each large flavor capsule contains 2-4 smaller capsules. When the large capsule bursts, the smaller capsules disperse and also burst, resulting in a wider diffusion area for aroma compounds and a more uniform aroma distribution. The preparation of the flavor capsules of this invention is simple and has low production costs. Unlike existing methods that add flavor capsules to filter rods, the flavor capsules of this invention are directly placed into the tobacco shreds, resulting in simple operation, wider aroma diffusion, and a higher aroma concentration.
