Description

Technical Field

[0001] The present invention relates to the technical field of cigarette additive manufacturing, in particular to a cigarette popping bead wall material, a cigarette popping bead made from the wall material and applications thereof. Background Art

[0002] Popping beads, also known as tobacco microcapsules or flavoring beads, are widely used in the daily chemical, food, and tobacco industries due to their stable aroma, large flavor loading capacity, diverse flavor profile, and enhanced moisturizing properties. In 2021, popping beads, as an innovative cigarette category, accounted for 2.59% of national cigarette sales, a year-on-year increase of 14.38%, demonstrating positive growth momentum.

[0003] Under the existing technology, popping beads for cigarettes are usually made by the dripping method (concentric film forming), with a production efficiency of 20,000-30,000 beads per dropper per hour (2.8mm slim cigarette specifications). With the increasing variety of popping bead products, the demand for popping beads is also increasing, and the improvement of popping bead production efficiency is imminent. High-speed pill machines and other equipment (generally using pressurization or shaking to accelerate the dropping of pills, with an efficiency of about 80,000 beads per dropper per hour (2.8mm slim cigarette specifications) or more) have come into being. However, under the existing technology, there is a certain degree of difficulty in selecting popping bead wall materials suitable for the high-speed pill drop process. On the one hand, the type and proportion of the wall material mixed glue affect the properties and stability of the popping bead rubber. On the other hand, the viscosity of the mixed glue solution has a greater impact on the rubber molding under the high-speed pill drop process. If the viscosity is too high, it will be difficult to cut during high-speed pill drop, and problems such as tailing, droplets, and adhesion will occur; if the viscosity is too low, it will cause a long gel time, unstable rubber molding, and deformation, white eyes, and cutting edges of the popping beads themselves. Under existing technology, the properties and viscosities of different gels vary greatly. In order to improve the production efficiency of popping beads, it is necessary to conduct in-depth research on the performance of wall material mixed glue based on the high-speed pelletizing process to ensure the quality of the finished popping beads. Summary of the Invention

[0004] This invention addresses the problems of existing popping bead wall materials being unsuitable for high-speed pellet production, resulting in low production yields and high pellet selection costs. By providing a popping bead wall material for cigarettes, the wall material solution exhibits low viscosity, good gelling properties, and high strength, making it suitable for high-speed pellet production. The resulting popping bead product exhibits excellent moisture resistance and environmental stability, is less susceptible to softening, sticking, cracking, or bubbles during long-term storage, and is safe and odorless.

[0005] In order to achieve the purpose of the present invention, the technical solution of the present invention is as follows:

[0006] A popping bead wall material for cigarettes comprises the following raw materials in parts by weight: 2.5-3.8 parts of mixed glue, 0.5-0.8 parts of a modifier, 0.01-0.02 parts of a curing agent, and 80-90 parts of deionized water. The mixed glue comprises the following components in a mass ratio: carrageenan: fenugreek gum: instant agar: pullulan in a mass ratio of 3-7:4-6:3-7:1-2.

[0007] The carrageenan is selected from one or a combination of K-type carrageenan, I-type carrageenan, and L-type carrageenan. In a preferred embodiment, the carrageenan is K-type carrageenan.

[0008] The instant agar is an agar that dissolves quickly at 65-85°C. In a preferred embodiment, the instant agar is produced by Wuhan Tyco Biotechnology Co., Ltd., No. SY-6001, and its technical indicators meet the national standard: GB1975-2010, with a gel strength of 700±100g / cm 2 (Test method: GB1975-2010).

[0009] The improver is selected from one or more of glycerol, butylene glycol, and propylene glycol, and the curing agent is selected from one or more of potassium chloride, calcium chloride, and sodium chloride.

[0010] The popping bead wall material for cigarettes of the present invention may further include a colorant and / or a preservative. Preferably, the colorant is present in an amount of 0.01-0.02 parts, and the preservative is present in an amount of 0.01-0.02 parts. The preservative is selected from one or more of sodium sorbate, potassium sorbate, sodium propionate, and sodium dehydroacetate. The colorant is selected from the food additives tartrazine, sunset yellow, brilliant blue, or amaranth.

[0011] A preferred embodiment of the present invention comprises 3.0-3.2 parts of a mixed gum, 0.6-0.7 parts of an improver, 0.01-0.02 parts of a curing agent, and 85 parts of deionized water. The optimal mass ratio of carrageenan, fenugreek gum, instant agar, and pullulan in the mixed gum is 5:5:5:1. Furthermore, the mixed gum further comprises 0.01-0.02 parts of a colorant and 0.01-0.02 parts of a preservative.

[0012] The tobacco bead wall material described herein is suitable for high-speed pellet production. The wall material solution has a low viscosity of 100-250 mPa·s (according to GB / T 5561-2012, solution temperature 75±1°C, rotor 2 60 rpm). Using a single-drip high-speed pellet machine, pressurization can be used to increase the core liquid flow rate. At a constant pressure of 2 kg, the flow rate can reach 11.5-13 ml / min, resulting in a stable pellet state and an efficiency of approximately 80,000 pellets per hour (2.8mm slim cigarette specifications) per dripper.

[0013] Another object of the present invention is to provide a tobacco popping bead comprising the tobacco popping bead wall material and core material of the present invention.

[0014] In one embodiment of the present invention, the core material comprises essence and caprylic decanoate glyceride. The essence is mango essence or mint essence, accounting for 10-20% of the total weight of the core material.

[0015] Another object of the present invention is to provide applications of the tobacco popping beads described herein in the fields of cigarette flavoring and smoke filtration. These popping beads can be loaded with core materials such as flavors, fragrances, and food-grade lipophilic substances to enhance cigarette quality, improve flavor, and enhance smoothness. Furthermore, incorporating these popping beads into cigarette filters can improve filter structure, lower smoke temperature, reduce harmful components in smoke, and minimize irritation.

[0016] Advantages of the present invention:

[0017] The present invention studies the composition of the wall material glue and obtains a mixed glue suitable for the high-speed dripping pill process. The mixed glue is composed of carrageenan, fenugreek gum, instant agar, and pullulan in a certain proportion. Fenugreek gum in the mixed glue is rich in galactomannan, and the ratio of galactose to mannose in the polysaccharide is 1:1.2. Pullulan is a linear polysaccharide formed by polymerizing maltotriose repeating units connected by α-1,4 glycosidic bonds through α-1,6 glycosidic bonds, and has excellent film-forming and gas barrier properties. The two are supplemented by carrageenan and instant agar to form a cross-linked network to form a three-dimensional network structure, so that a large amount of water can be retained in the hydrogel. The synergistic effect of the four adhesives results in a wall material solution with low viscosity, excellent gelation, and high strength. This effectively reduces problems such as tailing, droplets, deformation, and white-eye during high-speed pellet production, enabling a pellet drop rate exceeding 80,000 pellets per hour (2.8mm slim cigarette specifications) per dropper head while maintaining a production yield exceeding 97%. The finished pellets exhibit excellent moisture resistance and environmental stability, maintaining a moisture content of 1-2% at ambient humidity levels of 30-70%. They are less susceptible to softening, sticking, cracking, or bubbles during long-term storage, and are safe and odorless. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 This is a common problem in the pill picking process during the pill making process: pill bursting. DETAILED DESCRIPTION

[0019] The specific steps of the present invention are described below by way of examples, but are not limited to the examples.

[0020] Unless otherwise specified, the terms used in the present invention generally have the meanings commonly understood by those skilled in the art.

[0021] The present invention will be described in further detail below in conjunction with specific examples and with reference to data. It should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention in any way.

[0022] In the following examples, various processes and methods not described in detail are conventional methods well known in the art.

[0023] Example 1 Effect of different concentrations of mixed glue on popping bead wall materials

[0024] Sample 1:

[0025] Weigh 8 grams of carrageenan (K-type carrageenan, purchased from Qingdao Haizhilin Biotechnology Development Co., Ltd.), 8 grams of fenugreek gum (purchased from Jiangsu Ruicheng Biotechnology Co., Ltd.), 8 grams of instant agar (purchased from Wuhan Tyco Biotechnology Co., Ltd.), and 1.6 grams of pullulan (purchased from Shandong Furuida Biotechnology Co., Ltd.) and mix them evenly to obtain 25.6 grams of mixed glue. Use a sealed glue tank to make the glue, add 900 grams of deionized water, preheat the glue tank to 50-60°C, and then add 0.1 grams of food additives amaranth, 1 gram of sodium chloride, 0.02 grams of sodium sorbate, 6 grams of propylene glycol, 1 gram of glycerol, and 25.6 grams of mixed glue in sequence while stirring, and seal and stir for 20 minutes. Transfer the wall material solution to a preheated insulation barrel with an oil bath temperature of 85-92°C. Use a SHZ-95P circulating water multi-purpose vacuum pump to pump air for about 20-30 seconds per time, and pump air 1-3 times until there are no bubbles in the wall material solution. Keep warm and let it stand for 2 hours before use.

[0026] The requirements for the solution of the front wall material are: red, clear and transparent, without lumps and bubbles, with a viscosity of 140±30mPa·s (according to GB / T 5561-2012, solution temperature 75±1℃, No. 2 rotor 60r / min), and a temperature of 83℃.

[0027] A single-drip, high-speed dripping machine is used for pellet production. Pressurization is used to increase the core liquid flow rate, maintaining a constant pressure of 2kg and a flow rate of 11.5-13ml / min. A rubber pump controls the flow rate of the wall material solution. Liquid paraffin is used as the coolant, and the cooling temperature is 8-7°C. The wall material solution coats the core liquid, forming an oil-in-water solution. Surface tension ultimately forms a spherical shape, which solidifies upon cooling to form wet capsules. The wet capsules are randomly inspected for strength and specifications. Qualified capsules undergo degreasing, drying, cleaning, screening, light inspection, and balancing to produce the final popping pellets.

[0028] Sample 2:

[0029] Weigh 10 grams of carrageenan, 10 grams of fenugreek gum, 10 grams of instant agar, and 2 grams of pullulan and mix them evenly to obtain 32 grams of mixed glue. Use a sealed glue tank to make glue, add 850 grams of deionized water, preheat the glue tank to 50-60 ° C, and then add 0.1 grams of food additive brilliant blue, 0.1 grams of food additive lemon yellow, 0.2 grams of potassium chloride, 0.02 grams of sodium dehydroacetate, 5 grams of propylene glycol, 2 grams of glycerol, and 32 grams of mixed glue in sequence while stirring, and seal and stir for 20 minutes. The wall material solution is transferred to an insulation barrel preheated in advance, and the oil bath temperature is 85-92 ° C. Use an SHZ-95P circulating water multi-purpose vacuum pump to evacuate air for about 20-30 seconds / time, and the number of evacuations is 1-3 times, until there are no bubbles in the wall material solution. Keep warm and let it stand for 2 hours.

[0030] The requirements for the solution before taking the wall material are: green, clear and transparent, without lumps and bubbles, with a viscosity of 200±30mPa·s (according to GB / T 5561-2012, solution temperature 75±1℃, No. 2 rotor 60r / min), and a temperature of 83℃.

[0031] A single-dropper high-speed pill machine is used for drop-making, with a cooling temperature of 10-11°C. The strength and specifications of the wet capsules obtained by drop-making are randomly inspected. After passing the inspection, they undergo a process of degreasing, drying, cleaning, screening, light inspection, and balancing to obtain the final popping pills.

[0032] Sample 3:

[0033] Weigh 12 grams of carrageenan, 12 grams of fenugreek gum, 12 grams of instant agar, and 2.4 grams of pullulan and mix them evenly to obtain 38.4 grams of mixed glue. Use a sealed glue tank to make glue, add 800 grams of deionized water, preheat the glue tank to 50-60 ° C, and then add 0.2 grams of food additives lemon yellow, 0.1 grams of calcium chloride, 0.02 grams of sodium propionate, 4 grams of propylene glycol, 3 grams of glycerol, and 38.4 grams of mixed glue in sequence while stirring, and seal and stir for 20 minutes. Transfer the wall material solution to a preheated insulation barrel with an oil bath temperature of 85-92 ° C. Use an SHZ-95P circulating water multi-purpose vacuum pump to evacuate for about 20-30 seconds / time, and evacuate 1-3 times to ensure that there are no bubbles in the wall material solution. Keep warm and let it stand for 2 hours.

[0034] The requirements for the solution of the front wall material are: green-yellow, clear and transparent, without lumps and bubbles, with a viscosity of 280±30mPa·s (according to GB / T 5561-2012, solution temperature 75±1℃, No. 2 rotor 60r / min), and a temperature of 83℃.

[0035] A single-dropper high-speed pellet machine was used for pellet production, with a cooling temperature of 12-13°C. The wet capsules were randomly inspected for strength and specifications. Those that passed the inspections underwent degreasing, drying, cleaning, screening, light inspection, and balancing processes to obtain the final popping pellets. The results are shown in Table 1.

[0036] Table 1

[0037]

[0038]

[0039] The results showed that when the mixed glue concentration was low (Sample 1), the wall material solution viscosity was low, and production efficiency was high. However, the gelation time was slightly longer, the rubber skin formation was unstable, and the wet capsule pelleting process was prone to problems such as cutting and deformation, which had a certain impact on the quality of the popping beads themselves. The production qualification rate was slightly lower than that of Samples 2 and 3. When the mixed glue concentration was high (Sample 3), the wall material solution viscosity was high, and the pelleting process was prone to adhesion and unsmooth cutting, which was not conducive to improving the production efficiency of popping beads.

[0040] This example further investigates the use of a common wall material mixed adhesive composite system in the prior art for a high-speed pelletizing process.

[0041] Comparative Example 1 Carrageenan-sodium alginate composite system:

[0042] Mix 20g of carrageenan, 2.5g of sodium alginate, 2.5g of sorbitol, and 5g of modified starch to obtain 30g of mixed glue. Add 750g of deionized water, 0.5g of calcium chloride, 10g of glycerol, and 30g of the mixed glue to a preheated glue tank. Heat to 85°C while stirring, then transfer to a preheated, insulated barrel with an oil bath at 85-92°C. Use an SHZ-95P circulating water multi-purpose vacuum pump to evacuate the solution, pumping 1-3 times for approximately 20-30 seconds until there are no bubbles in the wall material solution. Keep warm and let it rest for 2 hours before use.

[0043] The requirements for the solution of the front wall material are as follows: milky white, clear and transparent, without lumps and bubbles, with a viscosity of 430±30mPa·s (according to GB / T 5561-2012, solution temperature 75±1℃, No. 2 rotor 60r / min), and a temperature of 83℃.

[0044] We attempted to use a single-drip high-speed dripping pill machine for dripping, with a constant pressure of 2kg, a flow rate of 11.5-13ml / min, and a cooling temperature of 3-4°C. However, during the dripping process, we found that the wet capsules were not cut smoothly, and all the wet capsules contained large droplets, with serious conjoined capsules. Furthermore, because the wall material solution of this system takes a relatively long time to gel, the wet capsules cannot be quickly formed in the cup (the cooling temperature has been reduced to the minimum), and due to the influence of pressure, all of them have an oval shape. The final product, the popping pills, all have problems such as deformation, tailing, and conjoined capsules, making them worthless.

[0045] A single-drip, seamless pill machine (low-speed) was used for pellet production, with a core liquid flow rate of 3.5-4 ml / min, liquid paraffin as the coolant, and a cooling temperature of 12-13°C. Wet capsules were randomly inspected for strength and specifications. Those that passed the inspections underwent a series of processes, including degreasing, drying, cleaning, screening, light inspection, and balancing, to produce the final popping pellets. The results are shown in Table 2.

[0046] Comparative Example 2 Agar-gellan gum composite system:

[0047] Mix 8g of carrageenan, 32g of gellan gum, 36g of agar, and 4g of modified starch to obtain 80g of mixed gum. Add 904g of deionized water, 8g of sodium chloride, 3g of Tween-80, 5g of potassium sorbate, and 80g of mixed gum to a preheated gel tank. Heat to 85°C while stirring, then transfer to a preheated insulated bucket with an oil bath at 85-92°C. Remove bubbles using ultrasonic vibration, keep warm, and let stand for 2 hours before use.

[0048] The requirements for the solution of the front wall material are as follows: milky white, clear and transparent, without lumps and bubbles, with a viscosity of 480±30mPa·s (according to GB / T 5561-2012, solution temperature 75±1℃, No. 2 rotor 60r / min), and a temperature of 83℃.

[0049] We attempted to use a single-drip high-speed dripping pill machine for dripping, with a constant pressure of 2kg, a flow rate of 11.5-13ml / min, and a cooling temperature of 15-17°C. However, during the dripping process, we found that the wall material solution of this system had a short gel time, and the wet capsules formed quickly, but the viscosity was high, which made cutting difficult, and there was severe adhesion, so the wet capsules were connected and could not be formed.

[0050] A single-drip, seamless pill machine (low-speed) was used for pellet production, with a core liquid flow rate of 3.5-4 ml / min, liquid paraffin as the coolant, and a cooling temperature of 15-17°C. Wet capsules were randomly inspected for strength and specifications. Those that passed the inspections underwent a series of processes, including degreasing, drying, cleaning, screening, light inspection, and balancing, to produce the final popping pellets. The results are shown in Table 2.

[0053] Comparative Examples 1 and 2 are relatively common and representative popping bead wall materials in the prior art. Due to the inherent properties of the gel and the viscosity of the gel, the existing carrageenan-sodium alginate and agar-gellan gum composite systems are not suitable for high-speed pellet production. As shown in Table 2, the physical properties of the popping beads produced using the mixed gel system described in the present invention meet those of existing products (low-speed production) and outperform existing products in terms of production qualification rate and pellet production efficiency.

[0054] The moisture content of the popping bead samples 1 to 3 prepared by the high-speed dropping pill process of the present invention and the popping beads of control examples 1 and 2 prepared by the low-speed dropping pill process were measured at an ambient humidity of 30-70%. The results are shown in Table 3.

[0055] Table 3

[0056] Ambient humidity 30％ 40％ 50％ 60％ 70％ Water content of sample 1 (%) 1.21 1.37 1.62 1.68 1.79 Water content of sample 2 (%) 1.24 1.32 1.54 1.73 1.82 Water content of sample 3 (%) 1.22 1.41 1.52 1.75 1.87 Comparative Example 1 Water content (%) 1.25 1.67 2.58 3.06 3.78 Comparative Example 2 Water content (%) 0.59 0.69 0.73 0.79 0.89

[0057] Combining Tables 2 and 3, the results indicate that the popping beads produced using the carrageenan-sodium alginate composite system in the existing low-speed dripping pill process have poor water resistance and are prone to softening and sticking when humidity is too high. While the popping beads produced using the agar-gellan gum composite system in the existing low-speed dripping pill process have excellent water resistance, the gel of the agar-gellan gum composite system itself is not very tough, making the intermediate wet capsules easily breakable in subsequent production processes, resulting in a low production qualification rate and high pill selection costs.

[0058] The wall material solution produced by the mixed adhesive system employed in the technical solution of the present invention has a moderate viscosity, making it suitable for the high-speed pelletizing process. The resulting popping beads meet all physical specifications of existing products, surpassing existing products in terms of production qualification rate. The popping beads themselves exhibit excellent moisture resistance and stability, maintaining a moisture content of 1-2% at ambient humidity levels of 30-70%. They are also water- and heat-resistant, allowing for long-term storage.

[0060] Referring to Table 4, the preparation method of Sample 2 in Example 1 was used to prepare popping bead samples 4 to 8 with different gel ratios. The properties of the finished popping bead products were measured, and the results are shown in Table 5.

[0064] Sample 5 wall material solution: light green, clear and transparent, without lumps or bubbles, with a viscosity of 350±30 mPa·s (according to GB / T5561-2012, solution temperature 75±1°C, rotor No. 2 60 r / min).

[0070] Result shows, in the wall material mixed glue of the present invention, fenugreek glue, as one of the main materials constituting wall material, is rich in galactomannan, can improve colloid structure with carrageenan, instant agar synergy, further promote gel strength and toughness. Lack of fenugreek glue can cause wet capsule to be difficult for forming, finished product burst bead hardness to decrease suddenly, appearance is unqualified, production qualification rate is extremely low and other problems (sample 4). Fenugreek glue solution itself has lower viscosity, and appropriate addition can improve the hardness of wet capsule, finished product burst bead itself when ensuring that wall material solution viscosity does not increase suddenly, when mixed glue concentration is certain, lack of fenugreek glue can make wall material solution viscosity increase suddenly, cause tailing, conjoined problems, and the toughness of burst bead itself, water retention variation, production qualification rate is relatively low (sample 5). Comparing sample 2 and sample 6, the addition of pullulan can effectively increase the compactness of wall material, can prevent core liquid from volatilizing to a certain extent, effectively reduce the appearance of problems such as oil seepage, bubble, empty shell.

[0071] The results of the study on sample 7 showed that too much instant agar would reduce the toughness of the wall material gel, making the wet capsules relatively easy to break in the subsequent production process, and reducing the production qualification rate. The results of the study on sample 8 showed that too much carrageenan would make the wall material solution relatively viscous, and the phenomenon of adhesion and unsmooth cutting would easily occur during the pelleting process, which would affect the production efficiency and the quality of the finished popping beads. The quality of the popping beads produced when the mass ratio of carrageenan, fenugreek gum, instant agar and pullulan in the mixed gel was 5:5:5:1 was the best (sample 2).

[0082] As shown in Table 6, by comparing samples 2 and 10, the addition of 0.01-0.02 parts of the curing agent potassium chloride can strengthen the colloidal structure to a certain extent, increase the hardness of the wet capsule, and make it less likely to deform. By comparing samples 2 and 9, it is found that the depression value of sample 9 decreases sharply, while the SD value increases sharply (the depression value is related to the compression ratio of the popping bead, which can reflect the toughness of the popping bead itself; the SD value can reflect the production stability to a certain extent. A larger SD value indicates a decrease in production stability and a decrease in the quality of the finished product). This shows that the addition of 0.5-0.8 parts of the modifiers propylene glycol and glycerol can balance the moisture in the popping bead wall material and the environment, so that the finished popping bead will not crack or bubble in a dry environment, and can improve the toughness and stability of the finished popping bead.

[0083] Based on the research results of Examples 1 to 3, a preferred solution of the present invention is: 3.0 to 3.2 parts of mixed glue, 0.6 to 0.7 parts of improver, 0.01 to 0.02 parts of curing agent, 0.01 to 0.02 parts of colorant, 0.01 to 0.02 parts of preservative and 85 parts of deionized water, and the mass ratio of carrageenan, fenugreek gum, instant agar and glucuron polysaccharide in the mixed glue is 5:5:5:1, which is the best. The physical indicators of the finished product of the popping beads prepared using this formula all meet the product indicators of the existing technology, and are superior to the products of the existing technology in terms of production qualification rate, which can reduce the cost of picking pills to a certain extent and improve efficiency. The popping beads prepared by this formula have good moisture resistance and stability, relatively stable moisture content in an open environment, certain waterproof and heat-resistant capabilities, and are not prone to softening, adhesion, cracking, bubbles and the like during long-term storage.
