Background technique

For the health of consumers, the tobacco industry has been promoting the harm reduction and tar reduction of cigarette products for many years. The tar content of traditional cigarettes has dropped from more than 20 mg to about 10 mg year by year. But lower harm and better satisfaction are often a contradiction. 3mg tar cigarettes are a kind of cigarettes that are less harmful to human health. One of its drawbacks is that the cigarettes have a small amount of smoke on the senses. The amount of smoke of tar cigarettes above 6mg is relatively good, but the harmfulness increases accordingly.

Therefore, it is necessary to develop a new type of low-hazard cigarettes that have been smoke-enhancing treatment, that is, to further enhance the smoking effect of cigarettes on the basis of low-hazard cigarettes, while also considering reducing the negative effects of smoke-enhancing agents and extending cigarettes Shelf life.

Further, the melting point of the smoke enhancing agent is greater than or equal to 30°C. When the melting point of the smoke enhancer is greater than or equal to 30°C, it can maintain a solid state at room temperature, and the cigarette can maintain a dry state in terms of the overall look and feel, especially the hand, so as to be consistent with traditional cigarettes. In addition, the dried tobacco flakes and/or shredded tobacco will not weaken the tensile strength of the cigarette paper, so that ordinary cigarette paper can be used for wrapping without using high-cost cigarette paper with special wet tensile strength.

Further, the smoke enhancing agent has low deliquescent properties, so that the macular projection area of the smoke-enhancing low-hazard cigarettes is less than 50 mm ² per stick after being placed continuously in an environment of 40° C. and 80% RH for 25 hours. Choosing a smoke enhancer with low deliquescent properties can reduce the risk of deliquescence and macula appearing on the outer surface of cigarette paper due to the strong hygroscopicity of the smoke enhancer, extend the shelf life of cigarette products, and reduce the incidence of macular smoke. In addition, the humidity control range of the cigarette manufacturing environment can be broadened to 30%-60%, that is, there is no need for production in a special closed dry production workshop, thereby greatly reducing production energy consumption.

Further, the smoke enhancing agent is composed of one or more harmless organic compounds, and the unit tar H value of the smoke-enhancing treated low-hazard cigarette after adding the harmless organic compound is less than or equal to 0.65, or Less than or equal to 0.6, or less than or equal to 0.55, or less than or equal to 0.5, or less than or equal to 0.45. Furthermore, the _{value of X HCN} is less than or equal to 60μg/piece; or the _{value of X NNK} is less than or equal to 3.0ng/piece; or the _{value of X NH3} is less than or equal to 6.5μg/piece; or the value of X _B[a]P is less than or equal to 8.2 ng/piece; or X _phenol value is less than or equal to 25μg/piece; or X _{crotonaldehyde} value is less than or equal to 12.5μg/piece. One or more harmless organic compounds are selected as the smoke enhancing agent.

The tobacco sheet produced directly from the tobacco sheet slurry corresponds to the tobacco tar release amount of T _{sheet ·mg/stick} , and the mass percentage of the first smoke enhancer in the smoke-enhancing treated tobacco sheet is M smoke1, so The smoke increase coefficient of the first smoke enhancer is S ₁ , the limit smoke increase tar equivalent of _{the first smoke enhancer} is T limit1, and the limit smoke increase tar equivalent of the first smoke enhancer corresponds to the smoke enhancer The content is M _limit1 , the smoke-enhancing processed tobacco includes traditional cut tobacco and a second smoke-enhancing _{agent, the corresponding tobacco tar release amount of the traditional cut tobacco is T tobacco} ·mg/piece, and the second smoke-enhancing agent accounts for The mass percentage of the cut tobacco treated with smoke increasing is M _smoke2 , the smoke increasing coefficient of the second smoke increasing _{agent is S 2} , the limit smoke increasing tar equivalent of the second smoke increasing _agent is T limit2, and the second smoke increasing agent is T limit2. The smoke-increasing limit of the second smoke-increasing _agent tar equivalent corresponds to the smoke-increasing agent content M limit2, and the above parameters meet the following requirements with an error of ±5%:

T _target ＝M _sheet ×(T _sheet +T _limit1 －S ₁ ×(M _limit1 －M _smoke1 ) ² )+M _tobacco ×(T _tobacco +T _limit2 －S ₂ ×(M _limit2 －M _smoke2 ) ² )

Relationship. The above formula can be used to obtain the tar equivalent of the whole cigarette. On the one hand, it is convenient to calculate the amount of smoke enhancer required for tobacco flakes and cut tobacco during the development of cigarettes, and on the other hand, the tar equivalent can be marked on the cigarette product package for easy consumption. The operator selects the cigarette product with the required amount of smoke production.

Further, the aerosol-generating substrate only includes smoke-enhancing treated tobacco flakes, and the tobacco flake raw materials for manufacturing the smoke-enhancing tobacco flakes include traditional tobacco flake slurry and a smoke-enhancing agent. The total particulate matter of the low-hazard cigarettes produced by heating the smoking set at 200°C is greater than or equal to 14.0 mg.

Example 3: Method 1 for manufacturing shredded tobacco treated with smoke enhancement

The first method of manufacturing smoke-enhancing treated tobacco: according to the original process of tobacco, the smoke-enhancing tobacco is manufactured according to the original process of tobacco, but in the process of manufacturing the smoke-enhancing tobacco, it is directly infiltrated into the tobacco, that is, the following steps:

Step 1: Pre-treat traditional cut tobacco according to the traditional manufacturing process of cut tobacco;

Step 2: Spray an appropriate amount of osmotic spraying smoke enhancer solution to traditional cut tobacco;

Step 3: Continue drying and other treatments in accordance with the traditional manufacturing process of shredded tobacco to manufacture shredded tobacco that has been smoke-enhancing treatment.

Because the smoke-enhancing agent in this method directly penetrates into the smoke-enhancing treated cut tobacco, it is only necessary to add the smoke-enhancing agent in the original traditional shredded tobacco manufacturing process, without modifying the manufacturing equipment and manufacturing process. Because the smoke-enhancing agent evenly penetrates into the smoke-enhancing cut tobacco, the surface of the smoke-enhancing cut tobacco is as smooth as traditional cut tobacco, and it is not easy to contact moisture in the air and deliquescence.

Example 4: Method 2 for manufacturing shredded tobacco treated with smoke enhancement

In this method, the smoke enhancer is directly attached to the surface of the tobacco by mixing the smoke enhancer, which is beneficial to improve the atomization effect of the smoke enhancer, especially when the cigarette is ignited or heated at high temperature, the smoke enhancer attached to the surface of the tobacco sheet is affected When there is a little heat, it will quickly atomize, and most of the smoke enhancers have not undergone combustion reaction or high temperature decomposition, thereby further reducing the hazard.

Example 5: Manufacturing method of low-hazard heating cigarettes treated with smoke enhancement

According to the requirements of taste, aroma, and tar equivalent of the whole cigarette, the smoke-enhancing treated tobacco flakes manufactured in Examples 1 and 2 are appropriately selected as the aerosol generating substrate, and the tobacco flakes are shredded or crimped according to the traditional cigarette manufacturing method. Cigarette paper is used together with the filter tip for wrapping. If necessary, additional structures such as cooling section and bursting beads can be added to produce low-hazard heating cigarettes that have been smoke-enhancing treatment.

Example 6: Manufacturing method of low-hazard burning cigarettes treated with smoke enhancement

According to the requirements of taste, fragrance, tar equivalent of the whole cigarette, etc., the smoke-enhancing treated tobacco produced in Examples 3 and 4 is appropriately selected as the aerosol generation substrate. According to the traditional cigarette manufacturing method, the tobacco paper is used together with the filter. In the roll pack, additional structures such as popping beads can also be added when necessary to produce low-hazard burning cigarettes that have been smoke-enhancing treatment.

Example 7: Manufacturing method of low-hazard dual-use cigarettes treated with smoke enhancement

According to the requirements of taste, aroma, tar equivalent of the whole cigarette, etc., the smoke-enhancing treated tobacco flakes and the smoke-enhancing tobacco shreds manufactured in Examples 1 to 4 are appropriately selected as the aerosol generation substrate. According to the traditional cigarette manufacturing method, Tobacco slices are shredded or crimped, and shredded tobacco is mixed, and then wrapped with cigarette paper and filter tips. If necessary, additional structures such as cooling section or popping beads can be added to produce low-hazard dual-use cigarettes that have been smoke-enhancing treatment.

When a smoke-enhancing agent with low deliquescent properties is selected, the humidity control range of the manufacturing and production environment of the above embodiments 1-7 can be expanded to 30%-60%, that is, there is no need to produce in a special closed dry production workshop, thereby greatly reducing production Energy consumption.

Example 8: Total particulate matter experiment one

A commonly used means to characterize the amount of cigarette smoke is Total Particulate Material (TPM), which can be based on the method provided by GB/T 19609-2004 "Total Particulate Material and Tar with a Smoking Machine for Routine Analysis of Cigarettes" Experiments were performed to obtain the total particulate matter production per unit weight of tobacco material (unit: mg/stick).

The method of Example 3 is used to produce smoke-enhancing treated tobacco. The traditional cut tobacco selected is 3 mg of tobacco cut from Zhongnanhai tobacco sticks, and the sprayed smoke-enhancing agent solution is a 50% butanetetraol aqueous solution. The smoke-enhancing agent solutions are adjusted separately Using the dosage, 5 kinds of smoke-increasing treated tobacco with tetramethylol content of 5%, 10%, 15%, 20% and 25% of the mass percentage of the final smoke-increasing treated shredded tobacco are prepared in sequence.

The above-mentioned traditional shredded tobacco and 5 kinds of tobacco shreds treated with increasing smoke were respectively wrapped into cigarettes according to the manufacturing method in Example 6.

First of all, the smoker uses the ignition smoking method to conduct sensory evaluation according to GB5606.4-2005 and the sensory evaluation method of Chinese cigarettes. The five low-hazard cigarettes treated with smoke-enhancing treatment are less harmful than the traditional smoke-enhancing agent. In cigarettes, the choking sensation, nasal irritation and dryness are all reduced, the aftertaste is slightly unclean, and the permeability of the fragrance is medium and slightly insufficient.

Secondly, the total particulate matter in the mainstream cigarette smoke was measured according to the method of GB/T 19609-2004, and the specific results are shown in Figure 1.

It can be seen that the total particulate matter will increase with the increase of the mass percentage of butylerythritol in the cut tobacco as a smoke enhancer, but the increase is gradually reduced, and there is a diminishing marginal effect, and when the mass percentage of the smoke enhancer reaches 25 %, the smoke-increasing effect is close to the limit, even if the mass percentage of the smoke-increasing agent is further increased, it is difficult to see the further smoke-increasing effect.

Especially when the content of tetramethylolmethane is 15%, the TPM value of the total particulate matter of the smoke captured by the Cambridge filter is 8.80, while the TPM value of the traditional cut tobacco with 0% butylerythritol content is 5.08, which is an increase of By 73.2%, the smoke increasing effect is significant.

Example 9: Infrared shading rate experiment one

Another commonly used method to characterize cigarette smoke volume is infrared shading rate, which can be measured by igniting and puffing the sample on a smoking machine according to the Canadian deep puffing mode. The larger the value, the higher the smoke concentration.

According to the method of Example 8, the traditional low-hazard cigarettes and the smoke-enhancing low-hazard cigarettes with 15% butanetriol content were manufactured according to the Canadian deep smoking mode (the smoking time is set to 3 seconds) on the smoking machine. Infrared shading rate measured by igniting suction.

Table 1 Infrared shading rate of different cigarettes:

Infrared shading rate/% Traditional low-hazard cigarettes Cigarettes containing 15% butanetriol First mouth 42 48 Second mouth 46 57 Third mouth 49 60 Fourth mouth 47 63 Fifth mouth 46 64 Sixth mouth 45 62

Seventh mouth 45 60

The larger the value in Table 1, the higher the concentration of smoke, from which the actual amount of smoke can be seen. Obviously, the sample with butane erythritol added as a smoke enhancer is much higher than the sample without addition.

Example 10: Experiment 2 of total particulate matter

The method of Example 3 was used to produce smoke-enhancing treated tobacco. The traditional cut tobacco selected was 3 mg of tobacco cut from Zhongnanhai cigarettes, and the sprayed smoke-enhancing agent solution was a 50% pentapentane alcohol solution. The smoke-enhancing agent solutions were adjusted separately With the dosage, 5 kinds of smoke-increasing treated tobacco with pentapentane alcohol content of 5%, 10%, 15%, 20%, and 25% of the mass percentage of the final smoke-increasing treated tobacco are prepared in sequence.

The above-mentioned traditional shredded tobacco and 5 kinds of tobacco shreds treated with increasing smoke were respectively wrapped into cigarettes according to the manufacturing method in Example 6.

First of all, the smoker uses the ignited smoking method to perform sensory smoking in accordance with GB5606.4-2005 and the sensory evaluation method of Chinese cigarettes. The five low-hazard cigarettes treated with smoke-enhancing treatment are less harmful than the traditional smoke-enhancing agent. In cigarettes, the choking sensation, nasal irritation and dryness are all reduced, the aftertaste is slightly unclean, and the permeability of the fragrance is medium and slightly insufficient.

Secondly, the total particulate matter in the mainstream cigarette smoke was determined according to the method of GB/T 19609-2004, and the specific results are shown in Figure 2.

It can be seen that the total particulate matter will increase with the increase in the mass percentage of pentapentane alcohol as a smoke enhancer in the cut tobacco, but the increase rate gradually decreases, and there is a diminishing marginal effect, and when the mass percentage of the smoke enhancer reaches 25 %, the smoke-increasing effect is close to the limit, even if the mass percentage of the smoke-increasing agent is further increased, it is difficult to see the further smoke-increasing effect.

Especially when the pentanol content is 15%, the total particulate matter TPM value of the smoke captured by the Cambridge filter is 8.99, while the TPM value of the traditional cut tobacco with the pentanol content of 0% is 5.08, which is an increase of By 77.0%, the smoke-increasing effect is significant.

Embodiment 11: Infrared shading rate experiment two

According to the method of Example 10, the traditional low-hazard cigarettes and the smoke-enhancing low-hazard cigarettes with 15% pentapentane alcohol content were manufactured according to the Canadian deep puffing mode (puffing time is set to 3 seconds) on the smoking machine. Infrared shading rate measured by igniting suction.

Table 2 Infrared shading rate of different cigarettes:

Infrared shading rate/% Traditional low-hazard cigarettes Cigarettes containing 15% pentanol First mouth 42 76 Second mouth 46 76 Third mouth 49 77 Fourth mouth 47 79 Fifth mouth 46 80 Sixth mouth 45 77 Seventh mouth 45 78

The larger the value in Table 2, the higher the smoke concentration, from which the actual amount of smoke can be seen. Obviously, the sample after adding pentaerythritol as a smoke enhancer is much higher than that without adding.

In addition to the above-mentioned butanetriol and pentaerythritol, various types of butanetriol, pentaerythritol, pentaerythritol, hexanetriol, hexaerythritol, hexanol, hexanol, penterythritol, pentaerythritol, and hexanol Alcohols, enanthol and other sugars and sugar alcohol polyhydric alcohols all show smoke-increasing effects.

As the smoke enhancer of low-hazard cigarettes, harmless organic compounds are preferred, so that the unit tar H value of low-hazard cigarettes after the smoke-enhancing treatment is less than or equal to 0.6 after the smoke-enhancing agent is added, the cigarette can be considered to be at a relatively low level of harm , Where H value per tar = H value/tar content or equivalent. If the smoke-enhancing agent is further selected from the common food additives such as carbohydrates and/or sugar alcohols such as butylerythritol, pentaerythritol, hexanol, etc., the safety will be higher, and even if the cigarette is accidentally ingested, it will not cause serious consequences.

The H value is the evaluation index of cigarette hazard, and the calculation formula is as follows:

The tar content of traditional cigarettes refers to the total particulate matter that removes nicotine and moisture. The unit is mg. The tar content has a positive relationship with the amount of cigarette smoke. The higher the tar content, the greater the amount of cigarette smoke. However, in traditional cigarettes, all tars are usually regarded as hazardous substances produced by cigarettes. However, the actual tar content of the smoke-enhanced low-hazard cigarettes in the present invention is lower, but in order to facilitate the atomization amount to be compared with that of traditional cigarettes. For comparison, define the concept of tar equivalent, that is, the tar equivalent of low-hazard cigarettes treated with smoke enhancement refers to the total particulate matter that removes nicotine and moisture, and the unit is mg. The specific measurement method can refer to GB/T 19609-2004. The method of tar in mainstream cigarette smoke.

The method of Example 3 was used to produce smoke-enhancing treated tobacco. Among them, the traditional cut tobacco selected was single-material tobacco from Hunan Longshan Longshan C3F, and the sprayed smoke-enhancing agent solution was 50% butylerythritol in water, 50% Adjust the amount of the smoke-enhancing agent solution for the aqueous solution of pentanol and the aqueous solution of 50% hexanol, respectively, and the content of butane erythritol in the final dried smoke-enhancing treated tobacco is 15% by mass, and the content of pentanol Three types of cut tobacco treated with smoke increasing treatment accounted for 15% of the final dried cut tobacco treated with smoke increase, and the hexanol content accounted for 15% of the final dried cut tobacco treated with smoke increasing treatment.

According to the manufacturing method in Example 6, the traditional cigarettes were successively wrapped into four types of low-hazard cigarettes with increased smoke treatment with 15% butanetriol content, 15% pentaerythritol content, and 15% hexanol content. sample. For the above cigarettes, the cigarette hazard evaluation index was determined according to the above method.

Table 3 Cigarette Harmfulness Evaluation Index of Different Cigarettes:

sample Traditional cigarettes Butanetriol Pentapentaol Hexanol All draw resistance (kPa) 1.106 0.988 1.005 1.032 X _CO (mg/pc) 8.2 8.5 8.4 8.4 X _HCN (ug/support) 74.0 55.3 57.6 57.1 X _NNK (ng/piece) 3.4 2.5 2.8 2.3 X _NH3 (ug/support) 6.7 7.0 6.3 6.7 X _B[a]P (ng/branch) 8.5 8.2 8.2 7.4 X _phenol (ug/ branch) 28.0 14.7 14.4 12.5 X _{crotonaldehyde} (ug/ branch) 13.2 12.4 11.2 10.8 Hazard index H value 8.0 6.5 6.4 6.0 Total particulate matter TPM 14.3 16.6 17.3 17.1 Tar content or equivalent 11.7 12.9 14.0 13.8 Unit tar H value 0.6884 0.5037 0.4563 0.4349

It can be seen from Table 3 that the H value per unit tar of the cigarettes with butane erythritol, pentapentyl alcohol and hexanol alcohol added as smoke enhancers are all less than or equal to 0.65, which is significantly better than that of traditional cigarettes. Furthermore, the H value per unit tar is all less than Or equal to 0.6, or less than or equal to 0.55, or less than or equal to 0.5, or less than or equal to 0.45; further, X _HCN value is less than or equal to 60μg/piece; or X _NNK value is less than or equal to 3.0ng/piece; or X _NH3 less than or equal 6.5μg / branched; or X _{B [a] P} is less than or equal to 8.2ng / branched; X or less than or equal _phenol 25μg / branched; X _{crotonaldehyde} or less than or equal 12.5μg / support ; It can be considered that the harm of cigarettes is at a relatively low level.

Example 13: Cigarette shelf life experiment

The shelf life of cigarettes mainly depends on the hygroscopicity of cigarette products. For example, electrically heated aerosol-generating products usually contain a large amount of highly deliquescent propylene glycol and glycerol, and thus have a higher moisture content than conventional shredded tobacco cigarettes, which will greatly reduce the shelf life of such electrically-heated aerosol-generating products. Moreover, due to the relatively high specific heat of water, for electrically heated aerosol-generating products containing highly deliquescent substances, the heating temperature of the smoking set must be increased, which increases the risk of the decomposition of organic matter and the generation of harmful substances. Conventional shredded tobacco cigarettes cannot be added with high deliquescent substances, otherwise it will reduce the flammability and continuous burning of cigarettes. Therefore, in the smoke-enhancing treatment process for cigarettes, smoke-enhancing agents with low deliquescent properties are preferred.

The deliquescent properties of smoke enhancers can be obtained in the following ways:

Weigh 15.000±0.004g samples and place them in a 40℃, 80%RH constant temperature and humidity box, and investigate the water absorption and weight gain of the samples under different lengths of time.

Table 4 Deliquescence of different smoke enhancing agents:

The deliquescent property of the smoke-enhancing agent can be determined by calculating the weight gain percentage for 120 minutes. If the weight gain percentage of 120min is less than or equal to 8%, it can be considered to have low deliquescent; if it is less than or equal to 5%, it can be considered to have very low deliquescent; if it is less than or equal to 1%, it can be considered to have ultra-low deliquescent.

According to the method of Example 8, traditional low-hazard cigarettes and low-hazard cigarettes with increased smoke treatment with a content of butanetriol accounted for 15% were manufactured. According to the method of Example 10, a smoke-enhancing low-hazard cigarette containing 15% of pentanol content was produced.

Select 3 mg of shredded tobacco blown out of Zhongnanhai cigarettes and spray glycerol to prepare a control shredded tobacco sample with a glycerol content of 15% by mass of the final shredded tobacco, and wrap it into a control cigarette according to the manufacturing method in Example 6. The samples must be carried out in a special closed drying laboratory during the manufacturing process to ensure that the cigarettes are not deliquescent and maculas appear before the experiment.

As shown in Figure 3, the samples were opened and placed in a high temperature and high humidity environment (40° C., 80% RH) to observe the appearance of macula on the surface of the cigarette after deliquescence. In order not to touch the cigarette in the experiment, take a picture as shown in Figure 3, and then calculate the macular projection area in the photo (unit: mm ² /stick), the ratio of the macular projection area in the photo to the actual macular area of the cigarette Approximately 1:π. Record the macular projection area (unit: mm ² /branch) according to different time points.

Table 5 The macular projection area of different cigarettes and different time points:

Set time Traditional low harm Contains 15% butanetriol Contains 15% pentanol Contains 15% glycerol

To cigarette cigarette cigarette cigarette 0 hours 0 0 0 0 1 hour 0 1 1 11 2 hours 1 2 2 18 4 hours 3 6 7 52 6 hours 5 10 12 60 25 hours 19 39 43 86

It can be seen from Table 5 that, due to the low deliquescent properties of the selected butanetriol and pentaerythritol, the macula area of the cigarette is ^{still less than 50 mm 2 /piece after being placed continuously in an environment of 40° C. and 80% RH for 25 hours.} In addition to the above-mentioned cigarettes containing shredded tobacco, cigarettes containing tobacco flakes treated with low-deliquescent smoke-increasing agents such as butylerythritol and pentapentyl alcohol also have a longer shelf life. In addition, cigarettes that use low-deliquescent smoke-increasing agents such as butylerythritol and pentapentyl alcohol do not need to be manufactured in a special closed and dry environment.

Example 14: Cigarette tar equivalent test

The tar content of traditional cigarettes refers to the total particulate matter that removes nicotine and moisture. The unit is mg. The tar content has a positive relationship with the amount of cigarette smoke. The higher the tar content, the greater the amount of cigarette smoke. However, in traditional cigarettes, all tar is generally regarded as hazardous substances produced by cigarettes, and the low-hazard cigarettes with increased smoke treatment in the present invention have lower actual tar content, but in order to facilitate the comparison of the amount of atomization generated with traditional cigarettes , Defines the concept of tar equivalent, that is, the tar equivalent of low-hazard cigarettes that have been smoke-increased refers to the total particulate matter that removes nicotine and moisture, and the unit is mg. The specific measurement method can refer to GB/T 19609-2004 to determine the mainstream cigarette The method of tar in the flue gas.

According to the method of Example 8, 5 kinds of low-risk cigarettes treated with smoke-enhancing treatment were manufactured with traditional low-hazard cigarettes and the smoke-enhancing agent butanetriol content of 5%, 10%, 15%, 20%, and 25%, respectively. Refer to GB/T 19609-2004 to determine the tar content in mainstream cigarette smoke to determine the tar content of traditional low-hazard cigarettes and the tar equivalent of five low-hazard cigarettes that have been smoke-enhanced. The specific results are shown in Figure 4.

It can be seen from Figure 4 that the relationship between the tar equivalent of the smoke-enhancing low-hazard cigarettes and the smoke-enhancing agent content can be approximately fitted to a quadratic function, that is: tar equivalent ≈ 5.75-47.143 × (smoke-enhancing agent content-24.32 %) ² .

Among them, 5.75 can be defined as the limit smoke increase tar equivalent of the smoke enhancer as T _limit , 47.143 can be defined as the smoke increase coefficient of the smoke enhancer as S, and 24.32% can be defined as the limit smoke increase tar equivalent of the smoke enhancer The corresponding smoke-enhancing agent content is M _limit .

In addition to the tobacco shreds and smoke enhancers used in the above experiments, tobacco flakes and other smoke enhancers also exhibit the above rules. After careful verification, they all satisfy the quadratic function relationship within ±5% of the error. Therefore, in the process of cigarette product design and development, the tar equivalent of the cigarette as a whole can be obtained by the following formula. On the one hand, it is convenient to calculate the amount of smoke enhancer required for tobacco flakes and shredded tobacco in the process of cigarette development. On the other hand, it can The tar equivalent is marked on the cigarette product package, so that consumers can choose the cigarette product with the required amount of smoke generation.

The tar target equivalent of the smoke-enhancing treatment of low-hazard cigarettes is T _target ·mg/stick,

The mass percentage of the smoke-enhancing treated tobacco sheet to the aerosol generating matrix is M _sheet ,

The mass percentage of the smoke-enhancing processed tobacco to the aerosol-generating substrate is M _tobacco ,

The tobacco sheet raw material for manufacturing the smoke-enhancing treated tobacco sheet includes a traditional tobacco sheet slurry and a first smoke-enhancing agent, and the tobacco sheet prepared directly from the traditional tobacco sheet slurry corresponds to a cigarette tar release amount of T _sheet ·Mg/piece, the mass percentage of _{the first smoke increasing agent} in the smoke-increasing treated tobacco sheet is M smoke1, the smoke increasing coefficient of the first smoke increasing _{agent is S 1} , and the first smoke increasing agent The limit smoke increase tar equivalent of _{the first smoke increase agent is T limit1} , and the smoke increase limit corresponding to _{the limit smoke increase tar equivalent of the first smoke increase agent} is M limit1,

The smoke-enhancing processed tobacco includes traditional cut tobacco and a second smoke-enhancing agent, the corresponding tobacco tar release amount of the traditional cut tobacco is T _tobacco ·mg/stick, and the second smoke-enhancing agent accounts for the smoke-enhanced tobacco. The mass percentage of the processed cut tobacco is M _smoke2 , the smoke increase coefficient of the second smoke enhancer is S ₂ , the limit smoke increase tar equivalent of the first smoke enhancer is T _limit2 , and the second smoke enhancer _{The smoke-increasing agent} content corresponding to the limit smoke-increasing tar equivalent is M limit2,

The above parameters meet the following requirements with an error of ±5%:

T _target ＝M _sheet ×(T _sheet +T _limit1 －S ₁ ×(M _limit1 －M _smoke1 ) ² )+M _tobacco ×(T _tobacco +T _limit2 －S ₂ ×(M _limit2 －M _smoke2 ) ² )

Relationship.

Example 15: Cigarette tar content/equivalent and hazard index experiment

In order to further verify that the smoke-enhancing treatment of low-hazard cigarettes did not increase the hazard while increasing the tar equivalent, according to the method of Example 8, two kinds of smoke-enhancing agents with butanetriol content of 10% and 20% were produced respectively. The processed low-hazard cigarettes are used to measure the tar content/equivalent and the hazardous H value together with the commercially available traditional cigarettes, Seven Wolf (Chongdian), Jiaozi (X Rose), and Seven Wolf (Chun Cui).

Table 6 Cigarette tar content/equivalent and hazard index:

Grade Box of cigarettes Measured tar content/equivalent Measured hazard index H value Example 10% / Equivalent 4.8 2.21 Example 20% / Equivalent 5.6 2.18 Seven wolves (classic) 5 Content 4.8 3.48 Jiaozi (X Rose) 6 Content 5.2 4.64 Seven wolves (pure cui) 6 Content 5.6 5.35

It can be seen from Table 6 that the low-hazard cigarettes treated with increased smoke increase the tar equivalent while still maintaining low hazard.

Example 16: Infrared shading rate experiment three

The method of Example 3 is used to produce smoke-enhancing treated tobacco, where the traditional cut tobacco selected is 3 mg of tobacco cut from Zhongnanhai tobacco sticks, and the sprayed smoke-enhancing agent solution is 50% butylerythritol in water, 50% pentane Five alcohol aqueous solution and 50% hexanol hexanol aqueous solution, respectively, adjust the amount of smoke enhancer solution, and the content of butane erythritol is 15% by mass of the final smoke-enhancing treated tobacco, and the content of pentanol is 15%. The final dried cut tobacco with increased smoke treatment has a mass percentage of 15%, and the content of hexanol accounts for 15% of the final dried cut tobacco with increased smoke treatment.

According to the method of Example 6, the above-mentioned shredded tobacco was used to manufacture traditional low-hazard cigarettes, four samples of low-hazard cigarettes with increased smoke treatment, with butanetriol content accounting for 15%, pentapentane alcohol content accounting for 15%, and hexanol content accounting for 15%. ，Respectively on the smoking machine in accordance with the Canadian deep suction mode (the suction time is set to 3 seconds), the infrared shading rate measured by the low temperature (200℃) heating and suction method of the heating appliance, the larger the value, the higher the smoke concentration high.

Table 7 Infrared shading rate of different cigarettes:

Infrared shading rate/% Traditional low-hazard cigarettes Contains 15% butanetriol Contains 15% pentanol Contains 15% hexanol First mouth 0 32 46 40 Second mouth 0 35 49 43 Third mouth 3 36 49 48 Fourth mouth 8 36 55 49 Fifth mouth 10 39 55 52 Sixth mouth 10 40 54 52

It can be seen from Table 7 that the traditional low-hazard cigarettes that have not been smoke-enhancing treatment can hardly release smoke during the heating process of the heating device, while the low-hazard cigarettes that have been smoke-enhanced can effectively release smoke, and the amount of smoke per puff is also relatively high. Evenly.

In addition to the above-mentioned butanetriol, pentaerythritol and hexanol, various types of butanetriol, pentaerythritol, pentaerythritol, hexanetriol, hexaerythritol, hexapentyl alcohol, pentaerythritol, pentyl alcohol, and hexanol Alcohol, enanthol and other sugars and sugar alcohol polyhydric alcohols all show smoke-increasing effects. In addition, adjusting the smoke-enhancing agent accounts for 5% to 25% of the mass percentage of the final dried cut tobacco after the smoke-enhancing treatment, which also has a significant smoke-enhancing effect.

In addition to the above-mentioned cigarettes containing shredded tobacco, tobacco flakes containing smoke-enhancing treatments with smoke-enhancing agents such as butylerythritol, pentapentyl alcohol and hexanol also showed higher infrared shading compared to tobacco sheets without smoke-enhancing treatment Rate.

The final dried cut tobacco with increased smoke treatment has a mass percentage of 15%, and the content of hexanol accounts for 15% of the final dried cut tobacco with increased smoke treatment. Propylene glycol and glycerol were sprayed on traditional shredded tobacco to prepare two sets of control shredded tobacco samples whose propylene glycol and glycerol content accounted for 15% of the final shredded tobacco mass.

According to the manufacturing method in Example 6, the traditional low-hazard cigarettes were successively wrapped into traditional low-hazard cigarettes, the low-hazard cigarettes which had been treated with increased smoke with 15% butanetriol content, 15% pentaerythritol content, and 15% hexanol content. 4 samples and 2 control samples with 15% propylene glycol content and 15% glycerol content.

In the smoking machine, according to the Canadian deep suction mode (the suction time is set to 3 seconds), the heating device is used for heating and suction at different temperatures, and the total particulate matter is measured respectively.

Table 8 Total particulate matter produced by heating different cigarettes:

It can be seen from Table 8 that when low-hazard cigarettes are treated with smoke-enhancing agents such as butylerythritol, pentapentyl alcohol and hexanol, the total particulate matter produced by heating the smoking appliance at 200°C can be greater than or equal to 14.0 Milligrams to meet consumer demand for smoke.

In addition to the above-mentioned cigarettes containing shredded tobacco, cigarettes containing tobacco flakes treated with smoke-enhancing agents such as butylerythritol, pentapentyl alcohol and hexanol, or cigarettes mixed with shredded tobacco and tobacco flakes can also be heated at 200°C.
