Technical Field

The patent relates to the technical field of low-harm cigarettes, in particular to a low-harm cigarette subjected to cigarette enhancement treatment.

Background

In order to keep the health of consumers, the tobacco industry has been promoting harm reduction and tar reduction of cigarette products for many years, and the tar content of traditional cigarettes is reduced from more than 20mg to about 10mg year by year. But lower hazard and better satisfaction are often contradictory. The 3mg tar cigarette belongs to a cigarette with small harm to human health, and has the defect of less smoke amount in the sense of the cigarette. The smoke amount of the tar cigarette with the tar content of more than 6mg is relatively good, but the harmfulness is correspondingly increased.

Therefore, there is a need to develop a new low-harm cigarette with smoke-increasing treatment, i.e. the smoking effect of the cigarette is further improved on the basis of the low-harm cigarette, and meanwhile, the negative effect of reducing the harm of the smoke-increasing agent is also considered, and the shelf life of the cigarette is prolonged.

The cigarette of the invention contains the cut tobacco subjected to smoke enhancement treatment, so that a larger amount of smoke can be generated on the premise of low harm in the ignition and smoking process. In addition, when the cut tobacco subjected to the smoke enhancement treatment is manufactured, the traditional cut tobacco and the smoke enhancement agent can be adopted, so that the difficulty of adjusting the sensory degree of the taste, the fragrance and the like of the cut tobacco is reduced, the research and development period is shortened, and the simplification of the production process is facilitated.

Further, the mass percentage of the smoke increasing agent in the cut tobacco subjected to smoke increasing treatment is greater than or equal to 5%. On the basis of a large number of experiments, the invention discovers that when the mass percentage of the smoke enhancer in the cut tobacco subjected to smoke enhancement treatment is more than or equal to 5%, the tobacco can generate a more obvious smoke enhancement effect on sense organs, and because the using amount of the smoke enhancer is very low, the harm brought by the smoke enhancer is very small, the influence on the sense organs such as the taste and the fragrance of the cut tobacco is also very small, the sense organs such as the taste and the fragrance of the cut tobacco do not need to be adjusted, the research and development period is greatly shortened, and the cigarette cost is rarely increased.

Further, the mass percentage of the smoke increasing agent in the cut tobacco subjected to smoke increasing treatment is greater than or equal to 10%. On the basis of a large number of experiments, the invention discovers that when the mass percentage of the smoke enhancer in the cut tobacco subjected to smoke enhancement treatment is more than or equal to 10%, the tobacco can generate a very obvious smoke enhancement effect in sense, the harm brought by the smoke enhancer is small due to low consumption of the smoke enhancer, the influence on the sense of the taste, the fragrance and the like of the cut tobacco is small, the difficulty in adjusting the sense of the taste, the fragrance and the like of the cut tobacco is low, the research and development period can be shortened, and the cigarette cost is slightly increased.

Further, the mass percentage of the smoke increasing agent in the cut tobacco subjected to smoke increasing treatment is less than or equal to 25%. On the basis of a large number of experiments, the invention discovers that when the mass percentage of the smoke enhancer in the cut tobacco subjected to smoke enhancement treatment reaches 25%, the smoke enhancement effect is close to the limit, if the mass percentage of the smoke enhancer is further increased, on one hand, the further smoke enhancement effect is difficult to find in sense, on the other hand, due to the excessive using amount of the smoke enhancer, the smoke enhancer can also have great influence on the sense of taste, aroma and the like of the cut tobacco, the difficulty in adjusting the sense of taste, aroma and the like of the cut tobacco is greatly improved, the cigarette cost is obviously increased, and the shelf life of cigarette products can be shortened due to the excessive smoke enhancer.

Further, the mass percentage of the smoke increasing agent in the cut tobacco subjected to smoke increasing treatment is less than or equal to 20%. On the basis of a large number of experiments, the invention discovers that when the mass percentage of the smoke increasing agent in the cut tobacco subjected to smoke increasing treatment is less than or equal to that, the smoke increasing effect is more obvious, and the addition of the smoke increasing agent has higher cost performance.

Further, the mass percentage of the smoke increasing agent in the cut tobacco subjected to smoke increasing treatment is between 12.5% and 17.5%. On the basis of a large number of experiments, the invention discovers that the mass percent of the smoke increasing agent in the cut tobacco subjected to smoke increasing treatment is between 12.5% and 17.5%, particularly when 15% is selected, the smoke increasing effect is obvious, meanwhile, the negative influence brought by the smoke increasing agent is in a controllable range, and the addition of the smoke increasing agent has high cost performance.

Further, the melting point of the smoke suppressant is greater than or equal to 30 ℃. When the melting point of the smoke enhancer is more than or equal to 30 ℃, the smoke enhancer can be kept in a solid state at normal temperature, and the cigarette can be kept in a dry state on the whole appearance, especially on the hand feeling, so that the smoke enhancer is consistent with the traditional cigarette. In addition, the dry tobacco sheet and/or tobacco shreds do not weaken the tensile strength of the cigarette paper, so that conventional cigarette paper can be used for wrapping without the need for costly cigarette paper having a particular wet tensile strength.

Further, the smoke increasing agent has low deliquescence, so that the projection area of the macula lutea of the smoke-increased low-harm cigarette after being placed in an environment with 40 ℃ and 80% RH for 25 hours is less than 50mm²And/or (b). The cigarette-increasing agent with low deliquescence is selected, so that the risk that the outer surface of cigarette paper of the cigarette is deliquesced and has yellow spots due to strong hygroscopicity of the cigarette-increasing agent can be reduced, the shelf life of the cigarette product is prolonged, and the incidence rate of yellow spot cigarettes is reduced. In addition, the humidity control range of the cigarette manufacturing production environment can be widened to 30% -60%, namely, the production is not required to be carried out in a special closed dry production workshop, and therefore, the production energy consumption is greatly reduced.

Further, the smoke increasing agent consists of one or more harmless organic compounds, and the unit tar H value of the low-harm cigarette subjected to smoke increasing treatment after the harmless organic compounds are added 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.

Detailed Description

The features and advantages of the patent will be set forth in the detailed description which follows, and in part will be readily apparent to those skilled in the art from that description or recognized by practicing the invention as described herein, as well as the appended claims, as illustrated in the appended drawings.

The invention relates to a low-harm cigarette subjected to smoke enhancement treatment, which comprises cigarette paper, a filter tip and an aerosol generating substrate, wherein the aerosol generating substrate comprises cut tobacco subjected to smoke enhancement treatment, and the cut tobacco subjected to the smoke enhancement treatment comprises traditional cut tobacco and a smoke enhancement agent.

Example 1: method for producing tobacco shred after smoke increasing treatment

A first method of manufacturing a tobacco shred subjected to smoke enhancement treatment: the method is characterized in that the cut tobacco subjected to the smoke increasing treatment is manufactured according to the original working procedures of the cut tobacco, and only in the process of manufacturing the cut tobacco subjected to the smoke increasing treatment, the cut tobacco is directly permeated into the cut tobacco, namely the following steps are carried out:

step 1: pretreating the traditional tobacco shreds according to the traditional tobacco shred manufacturing process;

step 2: spraying proper amount of permeability smoke increasing agent solution to the traditional tobacco shred;

and step 3: and (4) continuously performing drying and other treatments according to the traditional tobacco shred manufacturing process to manufacture the tobacco shreds subjected to the tobacco shred increasing treatment.

Because the smoke increasing agent directly permeates into the tobacco shreds after the smoke increasing treatment in the method, the smoke increasing agent is only added in the feeding link in the original traditional tobacco shred manufacturing procedure, and the manufacturing equipment and the manufacturing process are not required to be modified. Because the smoke increasing agent is uniformly permeated into the tobacco shreds after the smoke increasing treatment, the surfaces of the tobacco shreds after the smoke increasing treatment are as smooth as the surfaces of the traditional tobacco shreds, and the tobacco shreds are not easy to be contacted with the moisture in the air so as to be deliquesced.

Example 2: method two for manufacturing tobacco shreds after smoke increasing treatment

A second method of manufacturing a tobacco shred with enhanced smoking properties: the method is characterized in that the cut tobacco subjected to the cigarette enhancement treatment is manufactured according to the original process of the cut tobacco, and the cut tobacco subjected to the cigarette enhancement treatment is directly attached to the surface of the cut tobacco in the processes of manufacturing the cut tobacco subjected to the cigarette enhancement treatment by means of mixing and the like, namely the method comprises the following steps:

step 2: continuously carrying out drying and other treatments according to the traditional tobacco shred manufacturing process;

and step 3: the tobacco shred processed by the tobacco shred increasing treatment is manufactured by directly mixing a proper amount of the tobacco increasing agent into the traditional tobacco shred, and the tobacco increasing agent can be observed to be attached to the surface of the tobacco shred processed by the tobacco shred increasing treatment.

The method has the advantages that the smoke enhancer is directly attached to the surface of the cut tobacco in modes of mixing and the like, so that the atomization effect of the smoke enhancer is improved, particularly, under the condition that the cigarette is ignited or heated at high temperature, the smoke enhancer attached to the surface of the tobacco sheet is quickly atomized when the cigarette is heated by a little heat, and most of the smoke enhancer is not subjected to combustion reaction or pyrolysis, so that the harm is further reduced.

Example 3: method for manufacturing low-harm combustion type cigarette subjected to smoke increasing treatment

The tobacco shreds subjected to the smoke enhancement treatment manufactured in the examples 1 and 2 are appropriately selected as aerosol generating substrates according to requirements of taste, flavor, tar equivalent of the whole cigarette and the like, and simultaneously, an appropriate amount of tobacco sheets can be mixed.

Example 4: total particulate matter experiment one

A common characterization means of cigarette smoke amount is Total Particulate Matter (TPM), and experiments can be carried out according to the method provided by GB/T19609-2004 cigarette smoking machine for routine analysis to determine Total Particulate matter and tar, so as to obtain the Total Particulate matter generation amount (unit is mg/count) of tobacco Material per unit weight.

The method of example 1 was selected to produce tobacco shreds subjected to smoke enhancement treatment, wherein the selected conventional tobacco shreds were 3mg of tobacco shreds blown from the south China sea tobacco, the sprayed smoke enhancement agent solution was a 50% aqueous solution of erythritol, and the amount of the smoke enhancement agent solution was adjusted, to successively produce 5 types of tobacco shreds subjected to smoke enhancement treatment, in which the content of erythritol in the finally dried tobacco shreds subjected to smoke enhancement treatment was 5%, 10%, 15%, 20% and 25% by mass.

The conventional tobacco shreds and 5 types of tobacco shreds subjected to the tobacco enhancement treatment were each wrapped into cigarettes according to the manufacturing method in example 3.

Firstly, sensory evaluation is carried out by a smoker in a lighting and smoking way according to GB5606.4-2005 and a Chinese cigarette sensory evaluation method, and compared with the traditional low-harm cigarette without the smoke increasing agent, the 5 types of low-harm cigarettes subjected to smoke increasing treatment have the advantages that throat choking feeling, nasal cavity stimulation and dryness are reduced, the aftertaste is slightly unclean, and the penetrability of fragrance is slightly insufficient.

Secondly, total particulate matter in the mainstream smoke of the cigarette is determined according to the method of GB/T19609-2004, and the specific result is shown in figure 1.

It can be seen that the total particulate matter increases with the increase of the mass percentage of the erythritol serving as the smoke increasing agent in the cut tobacco, but the lifting amplitude gradually decreases, the marginal effect decreases, and when the mass percentage of the smoke increasing agent reaches 25%, the smoke increasing effect approaches the limit, and even if the mass percentage of the smoke increasing agent is further increased, the further smoke increasing effect is difficult to see.

Particularly, under the condition that the content of the erythritol accounts for 15%, the TPM value of the total particulate matters of the smoke collected by the Cambridge filter is 8.80, while the TPM value of the traditional cut tobacco with the content of the erythritol being 0% is 5.08, so that the promotion range reaches 73.2%, and the smoke increasing effect is obvious.

Example 5: infrared shading rate experiment 1

Another commonly used characterization of cigarette smoke levels is infrared opacity, which can be determined by smoking a sample on a smoking machine in the canadian deep draw mode, with larger numbers representing higher smoke concentrations.

Conventional low-harm cigarettes and cigarette-enriched low-harm cigarettes containing 15% of erythritol were manufactured as in example 4, and the infrared opacity was measured by smoking on a smoking machine according to the canadian deep smoking mode (smoking time set at 3 seconds), respectively.

Table 1 different cigarette infrared opacity:

the larger the value in table 1 represents the higher the smoke concentration, from which the actual size of the smoke quantity can be seen. It is clear that the samples with the addition of erythritol as a smoke booster are much higher than those without the addition.

Example 6: total particulate matter experiment 2

The method of example 1 was selected to produce tobacco shreds after smoke enhancement treatment, wherein the selected conventional tobacco shreds were 3mg of tobacco shreds blown from the cigarettes of south China sea, the sprayed smoke enhancement agent solution was a 50% aqueous solution of pentadiol, and the amount of the smoke enhancement agent solution was adjusted, to successively produce 5 types of tobacco shreds after smoke enhancement treatment, in which the pentadiol content was 5%, 10%, 15%, 20% and 25% by mass of the tobacco shreds after final drying.

Firstly, sensory smoking is carried out by a smoker according to GB5606.4-2005 and Chinese style cigarette sensory evaluation method, and compared with the traditional low-harm cigarette without the smoke increasing agent, the 5 types of low-harm cigarettes subjected to smoke increasing treatment have the advantages that throat choking feeling, nasal cavity stimulation and dryness are reduced, the aftertaste is slightly unclean, and the penetrability of fragrance is slightly insufficient.

Secondly, total particulate matter in the mainstream smoke of the cigarette is determined according to the method of GB/T19609-2004, and the specific result is shown in figure 2.

It can be seen that the total particulate matter increases with the increase of the mass percentage of the pentanol serving as the smoke increasing agent in the cut tobacco, but the lifting amplitude gradually decreases, the marginal effect is decreased, and when the mass percentage of the smoke increasing agent reaches 25%, the smoke increasing effect approaches the limit, and even if the mass percentage of the smoke increasing agent is further increased, the further smoke increasing effect is difficult to see.

Particularly, under the condition that the content of the pentanol accounts for 15%, the TPM value of the total particulate matter of the smoke collected by the Cambridge filter is 8.99, and the TPM value of the traditional tobacco shred with the content of the pentanol of 0% is 5.08, so that the promotion range reaches 77.0%, and the smoke increase effect is obvious.

Example 7: experiment 2 for infrared shading rate

Conventional low-harm cigarettes and cigarettes with smoke-enriched treatment containing 15% of pentanol were manufactured as in example 6, with the infrared opacity measured by smoking on a smoking machine according to the canadian deep-draw mode (the draw time was set at 3 seconds).

Table 2 infrared opacity of different cigarettes:

infrared opacity/%)	Traditional low harm cigarette	Cigarette containing 15% pentanol
			First port	42	76
Second port	46	76
			Third port	49	77
The fourth port	47	79
			Fifth port	46	80
Sixth port	45	77
			Seventh port	45	78

The larger the value in table 2 represents the higher the smoke concentration, from which the actual size of the smoke quantity can be seen. It is clear that the samples with pentanol added as a smoke suppressant are much higher than those without.

In addition to the above-mentioned butanetriol and pentanol, various kinds of saccharides, sugar alcohol polyols, and the like such as butanetriol, pentatriol, pentanetetraol, hexanetriol, hexanetetrol, heptatetritol, heptanetriol, and the like exhibit smoke-enhancing effects.

Example 8: index experiment for evaluating cigarette harmfulness

As the smoke enhancer for low-harm cigarettes, a harmless organic compound is preferred, so that the harmfulness of the cigarettes subjected to smoke enhancement treatment can be considered to be at a lower level when the H value of the unit tar of the cigarettes added with the smoke enhancer is less than or equal to 0.65, wherein the H value of the unit tar is H value/tar content or equivalent. If the smoke increasing agent further selects sugars such as tetrol, pentol, hexol and the like and/or sugar alcohol common food additives, the safety is higher, and even if the cigarette is eaten by mistake, serious consequences can not be caused.

The H value is a cigarette harmfulness evaluation index, and the calculation formula is as follows:

in the formula:

h is the harmfulness evaluation index of the cigarette;

X_COthe measured value of the CO release amount in the mainstream smoke of the cigarette is in mg/cigarette;

X_HCNthe unit is measured value of HCN release amount in mainstream smoke of the cigarette and is microgram/cigarette;

X_NNKthe unit is ng/count, which is an actual measured value of NNK release amount in the main stream smoke of the cigarette;

X_NH3the measured value of the release amount of NH3 in the mainstream smoke of the cigarette is measured in the unit of mug/cigarette;

X_B[a]Pfor benzo [ a ] in main stream smoke of cigarettes]Measured values of pyrene release amount in ng/count;

X_{phenol and its preparation}The measured value of the phenol release amount in the mainstream smoke of the cigarette is the unit of mu g/cigarette;

X_{crotonaldehyde}The unit is the measured value of the release amount of crotonaldehyde in the mainstream smoke of the cigarette and is mu g/cigarette;

C_CO、C_HCN、C_NNK、C_NH3、C_B[a]P、C_{phenol and its preparation}、C_{Crotonaldehyde}Respectively are weighted average values of the release amount in the main stream smoke of the cigarettes in China.

The determination of the sample CO is according to standard YC/T30-1996; HCN was determined according to standard YC/T253-2008; NNK is determined according to the standard GB/T23228-2008; NH3 was determined according to standard tobacco industry standards; the benzo [ a ] pyrene is determined according to the standard GB/T21130-2007; the phenol is determined according to standard YC/T255-2008; crotonaldehyde is measured according to standard YC/T254-2008.

The traditional cigarette tar content refers to total particulate matters for removing nicotine and moisture, the unit is mg, the tar content and the cigarette atomization occurrence amount are in a positive relation, and the higher the tar content is, the larger the cigarette atomization occurrence amount is. However, in the conventional cigarette, tar is generally regarded as a hazardous substance generated by the cigarette, while the actual tar content of the cigarette with low harm after smoke increase treatment is lower, but in order to compare the atomization generation amount with that of the conventional cigarette, the concept of tar equivalent is defined, namely, the tar equivalent of the cigarette with low harm after smoke increase treatment refers to a total particulate matter with nicotine and moisture removed, and the unit is mg, and the specific measurement method can refer to a method for measuring tar in the mainstream smoke of the cigarette in GB/T19609-2004.

The method of example 1 was selected to produce tobacco shreds with increased tobacco smoke, wherein the selected conventional tobacco shreds were single tobacco shreds of Hunan Xixi Longshan C3F, the sprayed smoke-increasing agent solution was a 50% aqueous solution of butanetetraol, a 50% aqueous solution of pentanol, and a 50% aqueous solution of hexanehexol, and the amount of the smoke-increasing agent solution was adjusted, respectively, to sequentially produce 3 kinds of tobacco shreds with increased tobacco smoke, in which the content of butanetetraol was 15% by mass of the finally dried tobacco shreds with increased tobacco smoke, the content of pentanol was 15% by mass of the finally dried tobacco shreds with increased smoke, and the content of hexanehexol was 15% by mass of the finally dried tobacco shreds with increased smoke.

The cigarette is wrapped into a traditional cigarette according to the manufacturing method in the embodiment 3, and the cigarette is a low-harm cigarette with the smoke increasing treatment, wherein the content of the butanetetraol, the content of the pentanediol and the content of the hexanetriol are 15 percent respectively. And respectively measuring the harmfulness evaluation indexes of the cigarettes according to the method.

Table 3 cigarette harmfulness evaluation indexes of different cigarettes:

as can be seen from Table 3, the H values of the unit tar of the cigarettes added with the tetrol, the pentol and the hexol as the smoke increasing agents are all less than or equal to 0.65, which is obviously superior to the traditional cigarettes, and furthermore, the H values of the unit tar are 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_HCNA value less than or equal to 60 μ g/count; or X_NNKA value less than or equal to 3.0 ng/count; or X_NH3A value less than or equal to 6.5 μ g/count; or X_B[a]PA value less than or equal to 8.2 ng/count; or X_{Phenol and its preparation}A value less than or equal to 25 μ g/count; or X_{Crotonaldehyde}A value less than or equal to 12.5 μ g/count; the cigarette harm may be considered to be at a lower level.

Example 9: shelf life test of cigarettes

The shelf life of a cigarette depends primarily on the hygroscopicity of the cigarette product. For example, electrically heated aerosol-generating articles typically have a higher moisture content than conventional cut filler cigarettes due to the inclusion of a high amount of highly deliquescent propylene glycol and glycerol, which greatly reduces the shelf life of such electrically heated aerosol-generating articles. Furthermore, due to the relatively high specific heat of water, electrically heated aerosol-generating articles containing highly deliquescent substances must be heated at elevated smoking article heating temperatures, increasing the risk of harmful substances being produced by the breakdown of organic matter. Conventional cut tobacco cigarettes also do not add highly deliquescent substances that would otherwise reduce the flammability and sustained combustibility of the cigarette. Therefore, in the case of subjecting a cigarette to a smoke increasing treatment, a smoke increasing agent having low deliquescence is preferred.

Deliquescence of the smoke booster can be obtained by:

weighing 15.000 +/-0.004 g of sample, placing the sample in a constant temperature and humidity box with the temperature of 40 ℃ and the RH of 80 percent, and inspecting the water absorption weight increment condition of the sample under different time lengths.

Table 4 different smoke boosters deliquescence:

the deliquescence of the smoke booster can be determined by calculating the percentage weight gain at 120 min. Low deliquescence may be considered if the percentage weight gain of 120min is less than or equal to 8%; if less than or equal to 5% it is considered to have a very low deliquescence; if less than or equal to 1%, it is considered to have an ultra-low deliquescence.

Conventional low-harm cigarettes and cigarette-enriched low-harm cigarettes containing erythritol in an amount of 15% were manufactured as in example 4. A cigarette with reduced harm of 15% of pentadiol was produced as in example 6.

Selecting 3mg of cut tobacco blown from the south China sea tobacco, spraying glycerol to obtain a control group cut tobacco sample with the glycerol content accounting for 15% of the final cut tobacco mass percent, and wrapping the control group cut tobacco sample according to the manufacturing method in the embodiment 3, wherein the manufacturing process needs to be carried out in a special closed drying laboratory, so that the condition that the cigarette is not deliquesced and has yellow spots before the experiment is ensured.

As shown in FIG. 3, the samples were placed in an open environment of high temperature and high humidity (40 ℃ C., 80% RH) to observe the appearance of yellow spots on the deliquesced surface of the tobacco rod. In order to avoid touching cigarette in experiment, the method takes a picture as shown in figure 3, and then calculates the projection area (unit is mm) of the macula lutea in the picture²One) the ratio of the projected area of the yellow spots in the picture to the actual area of the yellow spots in the cigarette is about 1 to pi. According to differentProjected area of macula lutea at time point (unit is mm)²/branch) are recorded.

Table 5 yellow spot projection areas for different cigarettes and different time points:

as can be seen from Table 5, the low deliquescence of the selected tetratol and pentatol makes the macular area of the cigarette less than 50mm after the cigarette is continuously placed for 25 hours in the environment of 40 ℃ and 80% RH²And/or (b). In addition to the above-mentioned cigarettes containing cut tobacco, cigarettes containing tobacco sheets subjected to a smoke-enhancing treatment with a low-deliquescent smoke-enhancing agent such as erythritol and pentanol also have a long shelf life. In addition, cigarettes employing low-deliquescent smoke enhancers such as erythritol and pentanol need not be manufactured in a particularly sealed dry environment.
