Description

sh

The invention relates to cigarettes and other similar types of tobacco products and, in particular, to those tobacco products that have been introduced based on organic acids.

The purpose of the invention is to improve the taste of a cigarette while smoking.

The drawing shows the proposed cigarette

The cigarette contains a cylindrical rod 1 of smoking material, such as chopped tobacco filler, enclosed outside in a wrapper 2 o The ends of the rod are open, exposing the smoking material. The cigarette also has a filter 3 located adjacent to one end of the tobacco rod so that the filter and the rod are coaxial and aligned with the ends, preferably abutting one another. Filter 3 has a cylindrical shape and its diameter is equal to the diameter of the tobacco rod. The ends of the filter are open, what provides

passing air and smoke through it “Filter 3 includes filtering material wrapped around a longitudinal surface with impermeable wrapping material 4 o Filter 3 attaches to tobacco rod 1 with mouthpiece material 5 which surrounds the filter along its entire length and the adjacent section of tobacco rod“ Internal the surface of the mouthpiece material 5 is fixedly attached to the outer surface of the impermeable wrapping material 4 and the outer surface of the wrap 2 of the tobacco rod, for which a suitable adhesive is used veschest- in. If necessary, a ventilated or air-dilutable cigarette can be made with air dilution means provided, such as a series of holes 6, each of which passes through the mouthpiece material 5 and the wrapping material 4.

The nicotine content in the used smoking material exceeds

2 wt% based on the dry weight of the smoking material, while the cigarette contains levulinic acid in dissociated and / or undissociated form in an amount greater than 1 wt% based on the dry weight of the smoking material. The term dry weight refers to the smoking material of smoking products and

means the mass of the smokable material after drying to constant mass at 101 ° C for 3 hours in a forced-draft oven.

The term nicotine content, as used in relation to the smoking material, means the mass of nicotine alkaloid when performing analysis and quantification by spectroscopic methods divided by the dry weight of the analyzed smoking material.

The smoking smoke-generating material from which the proposed cigarettes are made is most conveniently presented as a chopped filling material consisting of one or more tobacco materials having naturally high nicotine content. Tobacco (s) material (s) with naturally high nicotine content can (can ) used alone or as mixtures with (i) one or more tobacco materials having a low nicotine content, and / or (ii) one or more tobacco substitutes B redlagaemyh cigarettes of smokable material is characterized by a total content of nicotine or a nicotine content in the mixture greater than 2%.

In a typical case, the tobacco rod has a length of 50-85 mm, a circumference of 17-27 mm, and the wrapper is a conventional tissue paper. If necessary, a double wrapper system can be used. The tobacco rods and the resulting cigarettes can be made famous cigarette making equipment and related methods

Typically, the filter has a length of 20–25 mm and a circumferential length of 17–27 mm0. The filter can be made of any suitable material, such as cellulose acetate, polypropylene, tobacco material, etc. “Filters can be materials having such formulations or characteristics that exhibit low nicotine filtration efficiency. The wrapping material is usually a conventional paper sealing wrapper and can be either air permeable or substantial 5 1G) 2

but airtight. "However, if necessary, a cellulose acetate filter can be used without a wrapper." Various filters suitable for use in the invention can be made using known cigarette filter manufacturing methods and related equipment.

The mouthpiece material 5 surrounds the filter and the adjacent area of the tobacco rod so that the mouthpiece material extends 3-6 mm onto the tobacco rod with the mouthpiece. This material may have porosity, the degree of which may be different. For example, mouthpiece material may be substantially air impermeable, air permeable or treated (e.g. by mechanical or laser perforation techniques) so that the perforation area is obtained from ERSTU or channels are formed through which means for entry of a cigarette air dilution The total surface area of the perforations and the location of peroratsy periphery of the cigarette can be varied to allow cigarette consumption characteristics reguirovat

The term air dilution refers to the ratio (expressed as a whole in percent) of the volume of air drawn through the air-aids, to the total volume of air and aerosol drawn through a cigarette and exiting through the end-mouth portion of a cigarette. In the case of air-dilutable or ventilated cigarettes the amount of air dilution may vary. It is preferred that the amount of air dilution for a cigarette exceeds 20%, more preferably it is above 30%. The upper limit of air dilution for cigarettes are usually below 80%, often less than 6 (1%.

Smoking material used in the manufacture of tobacco rods may be different. For example, a tobacco material may be recycled into a process product, such as an extrudate (for example, as a foamed extruded rod or extruded into a tubular saw), be in the form of filler, such

Go as tobacco filler, and usually tobacco cigarette material is in the form of a cut filament. Terms filler and

chopped filler implies the coverage of tobacco materials that are in a form suitable for use in manufacturing

0 cigarette tobacco rods. The filler may include tobacco materials, which are mixtures and are presented in a form ready for making cigarettes. Tobacco

5 filler materials are usually used in extra-straws or crumbs, as is customary in traditional cigarette production. For example, cut tobacco filler material can be used in the form of straws, cut to a width of 1 / 25-1 / 60 inch, preferably 1 / 30- 1/40 inch Typically, such straws have a length of 0.25-3 inches o

Tobacco materials can be moistened and surface treated, as is usually done at various stages of cigarette production. For example, additives can be applied to the tobacco material, such as aromatizers and humidifiers, as is usually done in cigarette production. fragrances such as vanillin, cocoa,

5 licorice, menthol, aromatic tobacco oils, tobacco extracts and. Such supplements are most conveniently applied to the smoking material as surface treatment components.

0 The bulk of the present

in the smoking rod, the filler material is a tobacco material. However, tobacco material may be mixed with other smoking materials.

Tobacco (s) material (s), having (e) naturally high nicotine content, usually comprise at least a portion of the smokable filler material suitable for making the proposed smoking articles. Typically, such useful tobacco with a high nicotine content or processed tobacco with a high content nicotine is characterized by a nicotine content above 2.5% 0. Often, nicotine content in high-nicotine tobacco materials exceeds 3%, often higher than 4%, and in some cases above 5%. proposed tobacco materials does not exceed 10% „

High nicotine filler material can be varied. In particular, naturally occurring nicotine-rich tobacco is the leaves of the upper shoots of the commercial lines of Tobacco for flue-drying and Barley Tobacco. The natural nicotine content in many tobacco can depend on the agronomic conditions of tobacco cultivation, as well as specific genetic line of tobacco.

Technologically processed tobacco materials can be used. Such processed tobacco can be obtained by

Type of tobacco regeneration. (For example, materials can be manufactured using extrusion, sheet casting, long-threading or other papermaking processes. Raw materials used in the production of processed Tobacco can include the described high-nicotine tobaccos, or, at the technological stages of tobacco processing, they can be used Various types of tobacco extracts. Recycled tobacco can be produced under conditions suitable for producing products with different levels of nickname. Ting with Nicotine can be introduced into the foaming solvents ispol'uet

available for the production of bulk-expanded processed tobacco material having a high nicotine content. In addition, the processed tobacco materials include tobacco or tobacco materials, smetanny, combined or otherwise processed tobacco extracts, ta8

spraying and drying packaged materials or aromatic tobacco oils. Recycled tobacco materials have a high nicotine content after the completion of the process steps involved in their production or production process and prior to their use in the manufacture of cigarettes.

High-nicotine tobacco and / or high-nicotine processed tobacco can be used as tobacco material of cigarettes, as components of cigarette blends, or as part of components of cigarette blends. For example, high nicotine tobacco and / or high nicotine processed tobacco materials may be mixed with tobacco substitutes and / or tobacco materials having a nicotine content of less than 2%. So-called american rican blends having a high nicotine content (total content of nicotine in a mixture above 2%) are highly desirable for cigarette production. Typical total nicotine content in tobacco material or mixtures of materials from which tobacco rods are made for cigarettes offered above 2.25%, usually above 2.5%, more often above 3%, often above 3.5%, and in some cases above 4%.

Organic acids suitable for the production of cigarettes are any organic acids or organic compounds that behave like Lewis acids when contacted with nicotine. Examples of organic acids suitable for practicing the invention are aromatic acids, including benzoic acids and substituted acids. benzoic type, hydrochloric acids, heterocyclic acids, terpenic acids, sugar acids, such as pectic acids, amino acids, cycloaliphatic acids, dicarboxylic aliphatic acids

acids, keto acids, etc. Preferred Organic Acids

are straight chain and branched aliphatic acids, more preferably aliphatic monocarboxylic acids, and especially v keto aliphatic monocarboxylic acids. Examples of suitable organic acids include formic, acetic, propionic, isobutyric, butyric, alpha-methylmalic acid, methyl acetylmate, propionic, isobutyric acid, alpha-methyl acid, propionic, isobutyric acid, alpha-methyl acid, acetic acid, propionic acid, isobutyric acid, aliphatic monocarboxylic acid, and aliphatic acid. -methyl shaft erianovaya, karonovuyu, 2-furoevoy, fentsh acetic, heptane, octane, nonane, block, lemon, oxalic, malonic, glycolic, amber, ascorbic, tartaric, fumaric and pyrovin hydrofluoric acids, as well as lower fatty acids (tae, having carbon chains less C and higher fatty acids (i.e., having carbon chains from C to C20) and other such acids,. The most preferred is gamma-keto aliphatic acid, known under name levulic acid (CH3COCHNCH2COOH), Levulinic acid is also known as acetyl propionic acid, ag.-fa-ketovaleric acid and 4-hydroxy-pentanoic acid. Useful organic compounds that exhibit acidic character include phenolic compounds. Neni such as gua col, vanillin, protocatechualdehyde and

Numerous organic acids can improve the odor or aroma of the aerosol, since many organic acids are suitable flavors. However, whether a particular organic acid can act as a flavoring depends on the amount of particular organic acid used — the right one, and the aroma threshold of the particular acid used. Organic salts are used that give the cigarette specific aroma characteristics in small quantities so that undesirable tastes or odors do not appear in cigarettes0 Some organic acids are used in low enough quantities so that the cigarette does not acquire taste or aroma. be perceived as chemical, metallic, bitter, caustic or myeloid in nature or in dissonance with the general organoleptic characteristics of tobacco smoke

The most preferred organic acid is levulin acid. Such an organic acid can give a cigarette a calm, unsharp character, without contributing to any dissonant taste.

or odor; If necessary, some quantities of various other organic acids can be mixed with; Tevulinic acid and used as a seasoning. It is desirable that the main proportion of seasoning based on organic acids be levulinic acid,

Organic acid based seasoning can be introduced into a cigarette in various places. For example, organic acid or a mixture of organic kiglot can be applied to the filling material, introduced into the filling material throughout its mass or, in part, applied to the wrapping material of tobacco rod-1, introduced into the sizing line wrapping material tobacco rod, provided in the filter cigarettes and aphids If necessary, seasoning based on organic acid can be introduced to the processed tobacco For example, organic acids can be mixed with tobacco extracts or tobacco-aromatic oils and the resulting mixture of tobacco material and organic acid can be from eshan or otherwise used to process other tobacco or tobacco materials0 organic acid can be applied cigarettes or be present in a cigarette in an undissociated form and / or in a dissociated (eg, carboxylate) form.

The organic acid seasoning is introduced into the cigarette by mixing the seasoning with the tobacco material. The method of seasoning may vary depending on whether seasoning is diluted in liquid form or by placing seasoning in a cigarette. For example, seasoning may be introduced using syringes or methods such as spraying, moistening, electrostatic precipitation, soaking, garnish injections, spray drying, incorporation and encapsulation and

Suitable solvents for organic acids include water, ethanol, glycerin, propylene glycol and. . etc., as well as combinations thereof.

The amount of organic acid used in a cigarette may vary. The amount of organic acid added to a cigarette depends on factors such as the placement of the organic acid in the cigarette and

configuration aspects of cigarettes Configuration aspects cover the composition and characteristics of the filter material and the initial filling mixture, the degree of ventilation of the cigarette and other similar factors. For example, for most cigarettes containing tobacco material having a total or mixture nicotine content of 2-10%, it is often desirable to introduce 1–10% chesco-acid additive in a cigarette, calculated on the dry weight of tobacco filler, in order to provide an acceptable tobacco taste, strength and satisfaction when using “The amount of organic acid introduced into such a cigarette exceeds 2%, and often exceeds 3%, calculated on the dry weight of tobacco filler in a cigarette,

The presence of an organic acid (which can be provided by decomposing the nicotine salt and the organic acid by using a cigarette) can lead to a decrease in the mainstream aerosol pH, depending on the amount and type of organic acid introduced into the cigarette. Thus, a certain balance, softening or favorable combination of odors leads to the formation of a more complete tobacco flavor, strength and satisfaction that a smoker can use when consumed. Such characteristics of enhanced odor are especially desirable for cigarettes with strong air dilution or ultra-low emission.

At pH aerosol main stream

A number of factors influence. For example, the pH of the mainstream cigarette smoke may be influenced by such factors as the type of tobacco material or mixture of tobacco materials used, the type of processed tobacco (e.g., foamed tobacco or regenerated tobacco), cigarette configuration (e.g. filter packings, the degree of air dilution, the length of the circumference of a cigarette, the type of wrapping material and Т0п "), the characteristics of how cigarettes are smoked or smoked, and other factors

Offered cigarettes usually yield 0.2–3.5 mg, often 0.3–2.5 mg, usually 0.4–1.5 mg nicotine when smoked under conditions determined by the rules of the federal trade commission of CUIA. In a typical case, the tar / nicotine ratio (according to FTC standards) for cigarettes is less than 12, generally less than 9, often less than 7, and in some cases less than 5 °. The tar / nicotine ratio (according to FTC standards) for cigarettes can often be A 3-60 tar / nicotine ratio for cigarettes that have nicotine and organic acid salt injected can be reduced to 80% of this ratio for similar cigarettes that do not have the salt additive added.

Example K The salt of nicotine and levulinic acid is obtained by the following method. About 350 g of I-nicotine is loaded into a 1000 ml round-bottomed flask. About 10 g of granulated sodium hydroxide are loaded into the I-nicotine. The flask is placed in a heating jacket and a magnetic stirrer is injected. The nicotine solution is mixed using a magnetic mixing apparatus. Nicotine is subjected to vacuum distillation using a Todd column packed with glass spirals, and a fraction distilled at 97–98 ° C and a pressure of 10 mm is collected at a reflux ratio of about 10: 1. The collected distillate is transparent and resembles water. Nicotine purified in this way is used in the synthesis of the salt of 1-nicotine and levulinic acid.

Into a 500 ml round-bottom flask equipped with a magnetic stirrer and a heating jacket, 69.6 g (0.6 mol) of levulinic acid are loaded. Levulinic acid is desorbed using a conventional magnetic mixing device. Levulinic acid is used to work without further purification. Levulinic acid is heated to, to obtain its liquid form, and the liquefied component is subjected to mixing. 32.4 g (0.2 mol) of purified 1-nicotine are titrated to liquefied levulinic acid for 20 minutes. It is preferable to introduce nicotine into an organic acid in order to create an excess of acid relative to nicotine, which promotes salt formation. A transparent, viscous, yellow liquid weighing about 100 g is obtained. The product is sealed in a glass ampoule under nitrogen atmosphere. The product is levulinate I-nicotine (as determined by IR spectroscopy). The ratio of nicotine / levulinic acid is 1: 3 (as determined by destructive distillation in a 10% aqueous solution of sodium hydroxide followed by extraction with isopropanol and gas chromatography analysis of nicotine)

Cigarettes containing different amounts of 1-nicotine levulinate salt are prepared according to the following procedure:

Cigarettes with a length of about 99 mm and a circumference of 24.85 mm have tobacco rods 68 mm long and filters 31 mm long. The tobacco rod includes a load of cut tobacco weighing about 0.74 g contained in cigarette wrapping paper that is supplied commercially under the brand cigarette. paper Filters are manufactured using traditional cellulose acetate cigarette filter technology (2.7 denier per yarn, 48.000 denier in total) and surrounded with a breathable paper wrap having Coresta porosity of 26,000 ml / min. The tobacco rod and filter are joined by ends and fastened with mouthpiece paper having Coresta porosity equal to 3135 mp / min. The mouthpiece-paper is attached by glue to the filter, and the adjacent part of tobacco rod 0 Mouthpiece material surrounds the filter along the entire length and goes 3 mm into tobacco rod, The cigarettes described in this way are manufactured on an experimental-industrial cigarette-dividing machine. At the periphery of a cigarette, at a distance of 13 mm from its mouthpiece end, a ring of mechanically made holes is formed. rennye thus provide openings cigarettes, providing 507-ing air dilution cigarette Constructed designated as samples 1, 2, 3 and C-1 respectively, the sample of filler material from which each cigarette is manufactured

the rod is presented in the form of a straw, wound with a frequency of 32 cuttings per inch. The initial filling material includes a mixture of approximately 97 Barley tobacco, 41% of pipe-dried tobacco, 32% of regenerated tobacco material and 18% of Eastern Tobacco. The mixture is treated with a water-glycerin humidifier and Flavored

Four batches of chopped filling mixture are provided, each batch weighing 1520 g. The first batch is treated with 20 g of seasoning - 1-nicotine levulinate “The second batch is treated with 60 g of seasoning - 1-nicotine levulinate” The third batch is treated with 100 g of seasoning - 1-nicotine levulinate The fourth batch is not seasoned and used for comparison purposes.

Seasoning — Levuliate 1-nicotine is applied to the chopped filler by spraying using a hand sprayer to apply a 1: 1 mixture of water and seasoning.

Each of the four batches is separately placed in sealed plastic meg; ki and stored, 7. days at 706F. Then, four batches are individually mixed with 480 g of chopped filling mixture of 75 parts of Tarley frothy tobacco and 25 parts of froth-blown foamed tobacco. Foamed, chopped filler in the form of a mixture is added to each batch using a mixing drum g to obtain a high quality mixed mixture having a moisture content of 12-13%. 0 The resulting mixture from the first batch of filling material has about 17 levulinate 1-nicotine applied on it (in terms of per conditioned mass of the filler), which is designated as sample 10 The resulting mixture from the second batch of filler has about 3% levulinate 1-nicotine applied on it (in terms of the conditioned mass fill tel), which is designated as sample 2 o The resulting mixture from the third batch of filler has about 5% applied levulinate 1-nicotine (in terms of the conditioned mass of the filler), which is indicated as sample 3 "The resulting mixture from the fourth batch of filler not treated with levulinate

I-nicotine is used for comparative purposes and is designated as S-1 sample.

Various cigarettes were used for smoking. Data regarding (i) tar formation, nicotine and carbon monoxide, (ii) tar / nicotine ratios, (iii) nicotine content in a cigarette, (iv) puff numbers, (v)

The pH of the main stream aerosol for each sample is given in Table. one"

The data table. 1 show that various cigarettes have an increased nicotine content and give increased

nicotine indices (for FTC, conditions: 2 s, 58 cm smoldering) with an increase in the content of levulinate 1 nicotine. In addition, the resin / nicotine ratios for the samples decrease with increasing levels of levulinate 1-nicotine. Different cigarettes give similar rates of tar production, carbon monoxide production and puff numbers. Further, the samples according to the invention (samples 1-3) give a smoke of radiation that is generally lower than that of a sample that does not have an exogenous nicotine / organic acid salt (sample C -1) about

Estimates of the organoleptic properties of samples 2, 3 and C-1 show that a cigarette having about 5% salt additive (sample 3) provides a greater and smoother impact, as well as less sharpness than a cigarette not containing salt additive (sample C-1), Sample 2 did not differ organoleptically significantly from sample C-1 in terms of sharpness and general taste, even despite a significant increase in the nicotine content in the sample relative to the comparative sample. Thus, a nicotine-lingered additive allows to obtain cigarettes that have a relatively low tar / nicotine ratio, while still having a calm (i.e. not too sharp) taste. ,

The smoke pH is determined by a specific procedure. The minimum and maximum pH values given in Table 1 are calculated average values (minimum and maximum) for puffing, obtained for 8 puffs per cigarette.

Cigarettes with a length of about 84 mm and a circumference of 24.85 mm have tobacco rods 57 mm long and filters 27 mm long. The tobacco rod includes a load of cut tobacco weighing about 0.49 grams contained in cigarette wrapping paper that is supplied commercially under the brand cigarette paper 854 ,, Filters are manufactured using traditional cellulose acetate cigarette filter technology (2.1 denier per yarn, total 48000 denier), and surrounded with air-tight paper wrap Tobacco rod and filter The sides are folded and sealed with mouthpiece paper using air impermeable mouthpiece paper. The mouthpiece paper is attached with glue to the filter and the adjacent part of the tobacco rod. The mouthpiece material surrounds the filter along the entire length and extends 3 mm onto the tobacco rod. The cigarettes described in this way are manufactured on an experimental industrial cigarette making machine. A ring of laser holes is formed along the periphery of the cigarette at a distance of 13 mm from the mouthpiece end. The holes were passed through the mouthpiece paper and the sealing wrapper and were obtained using a laboratory laser punch. Perforated cigarette provides 75% air dilution. Cigarettes made in this way are designated as samples 4, 5, 6 and C-2, respectively, to a sample of the filling material from which each cigarette is made.

The filling material used to form the tobacco rod is presented in the form of a straw, sliced at a frequency of 32 cuts per inch. The starting material comprises a mixture of 43% Barley tobacco, 6% flue-cured tobacco, 19% regenerated tobacco material and 32% Turkish tobacco. The mixture is treated with a water-glycerin moisturizer and flavors are added to it.

Four batches of sliced filling mixture are provided, each - a batch weighing 940 g. The first batch is treated with 60 g of 1-nicotine-lultivate seasoning. The second batch “OPTIMATE 140 g T-NIKOTINLSVULINLTNONN seasoning, the third batch is treated with 200 g 1-nicotine-lulkinate pripra“ The fourth batch is not processed t I-nicotine-lurenate seasoning and used for comparative purposes,

I-nicotine lint dressing is applied to the chopped filler by spraying using a hand sprayer to apply a 1: 1 mixture of water and melts

Each of the four batches is individually placed in sealed plastic bags and stored for 2 days at 70 ° F0. Then, four batches are separately mixed with 1060 g of the cut filling mixture of 35 parts of Garli foam tobacco and 65 parts of foam fire-dried tobacco. The foam cut filler is added. for each batch using a mixing drum to obtain a well-mixed mixture having a moisture content of 12-13%. The resulting mixture gives for the first batch of filling material about 3% applied by i-hyg tin lulinate salt (in terms of the conditioned weight of the filler), which is designated as sample 4, the resulting mixture from the second batch of filler has about 7% of the applied I-nicotinlevulinate salt (in terms of the conditioned weight of the filler), which is designated as sample 5. The resulting the mixture from the third batch of filler has about 10% of the applied 1-nicotinlevulinate salt (in terms of the conditioned mass of the filler), which is indicated as sample 60 The resulting mixture from the fourth batch of filler, 1-treated nikotinlevulinatnoy salts, used for comparative purposes and is designated as Sample C-2,

A cigarette obtained in this way contains a nicotine-flavored seasoning, as well as an exogenous nicotine additive,

Different cigarettes were used to smoke J Data on (i) tar, nicotine and carbon monoxide, (ii) tar / nicotine ratios, (iii) nicotine in a cigarette, and (iv) puff numbers for samples 4-6 and C-2 are presented in table 20. In addition, in table. Table 2 shows the pH of the main stream aerosol for samples 4-6, C-2 and C-3,

The data table. Figure 2 shows that various cigarettes have an increasing nicotine content and give increasing nicotine values (FTC) with increasing levels of levulinate 1-nicotine. In addition, tar / nicotine ratios for samples decrease with increasing levels of levulinate I-nicotine. Different cigarettes give similar rates of tar production, carbon monoxide production and the number of puffs. In addition, the samples according to the invention (samples 4-6) give the smoke pH as a whole lower than that of a sample that does not have an exogenous nicotine / organic salt. acid (sample C-2). In addition, the overall pH of smoke for sample C-3 is much higher than that of any other sample.

Estimates of the organoleptic properties of samples 5, 6 and C-2 show that cigarettes with about 10% salt additive (sample 6) provide greater and smoother impact, as well as less sharpness than cigarettes that do not have salt additive (sample C-2 ) “All cigarettes provide a good tobacco taste and do not give a pronounced perceived chemical taste or non-cigarette taste.” It turned out that sample 5 does not differ significantly in organoleptic characteristics from sample C-2 in terms of its effect, its smoothness, sharpness and general taste. in spite of

The fact that the sample gives a higher nicotine content than the comparative sample. Sample C-3 is often sharp and tasteless. However, Sample 7 unexpectedly shows a calm smoking character and good taste, although the sample has a relatively high content of introduced exogenous nicotine.

The minimum and maximum pH values given are the calculated minimum and maximum values for puffs obtained for the puff per cigarette series. For samples 4, 5 and С-2, the number of puffs for calculating the average pH is 7 "For samples 6 and no. C-3, the number of pulls used to calculate the average pH is 6.

The filling material used to form the tobacco rod is presented in the form of a straw, sliced at a frequency of 32 cuts per inch. The starting material includes a mixture of 40% Barley tobacco with nicotine 57, 187 flue-cured tobacco, 3.5% nicotine, 30% regenerated tobacco material, 0.5% nicotine and 12% eastern tobacco mixture, and nicotine content 0.9% “The mixture is treated with a water-glycerin humidifier and flavors are introduced into it ,,

Four batches of sliced filling mixture are provided, each batch weighing 2000 g. The first batch is treated with 120 g of levulinic acid “The second batch is treated with 280 g of levulinic acid. The third batch is treated with 400 g of levulinic acid. The fourth batch is not treated with levulinic acid. The fourth batch is not treated with levulinic acid and is used for comparative purposes.

Seasoning - levulinic acid is applied to the chopped filler by spraying using a hand sprayer in the form of a 1: 1 mixture of water and seasoning. The amount of water in the water / seasoning mixture is introduced such that the final straw moisture is 15%.

Each of the four batches is separately placed in sealed plastic bags and stored for 2 days at 70 ° Fe. Then four batches are separately mixed with 2000 g of chopped filling mixture of 35 parts of Barley foamed tobacco, 4% nicotine content and 65 parts of foam-blown tobacco, drying containing nicotine 4%. Foamed chopped filler is added to each batch using a mixing drum to obtain a well-mixed mixture having a moisture content of 12-13%.

The resulting mixture gives for the first batch of filling material about 3% of applied levulinic acid (in terms of the conditioned weight of the filler), which equals 10

meant as sample 8 The resulting mixture from the second batch of filler has about 7% applied levulinic acid (in terms of the conditioned mass of the filler), which is designated as sample 9 "The resulting mixture from the third batch of filler has about 10% applied levulinic acid (in terms of per conditioned mass of the filler), which is designated as sample 10 The resulting mixture in the fourth batch of filler, not treated with levulinic acid, was used (for comparative purposes and indicated as head C-40

various cigarettes that have high-nicotine chopped filler (i.e. approximately 3% of the total nicotine content in the mixture) are characterized by comparable tar production, 40 nicotine and carbon monoxide, as well as comparable tar / nicotine ratios and puff numbers. However, cigarettes are according to the invention (samples 8-10, containing levulinate acid 45) give a lower pH value of the main stream for puffing and on average, when compared with the control (sample C-4, which does not contain levulinic acid). In addition, the data show that the pH of the smoke offered by cigarettes decreases significantly with an increase in the content of levulinic acid. A decrease in the pH of the smoke of the samples indicates a significant increase in the concentration of hydronium ion in tobacco smoke.

changing the organoleptic properties of smoke

The organoleptic evaluation of the samples shows that the cigarettes offered are perceived as calm when smoking, while the control sample is very sharp. The softness of samples 8 and 9 is considered comparable. The proposed cigarettes provide a good tobacco taste, strength and satisfaction when smoking. The control sample is very strong, and the feeling of excessively strong influence created by him does not bring satisfaction.

EXAMPLE 4 Cigarettes containing various amounts of levulinic acid are prepared using the following method. Cigarettes about 84 mm long and 24.85 mm long have tobacco rods 57 mm long and filters 27 mm long. The tobacco rod includes a load of cut tobacco weighing about 0.82 g contained in cigarette wrapping paper that is sold commercially under the brand cigarette paper 856 Filters are manufactured using traditional cellulose acetate cigarette filter technology (2.7 denier per thread, 48,000 denier), and is surrounded by air-permeable paper wrap with Coresta’s porosity of about 26,000 cm / min. The tobacco rod and filter are tied off with ends and sealed using — substantially impermeable to Air with mouthpieces of paper. Mouth-paper paper is attached with glue to the filter and the adjacent part of the tobacco rod. The mouthpiece material surrounds the filter along its entire length and goes 4 mm into the tobacco rod. The cigarettes described in this way are manufactured on an experimental-industrial cigarette-making machine. mm from the mouthpiece end a ring of laser holes is formed. A perforated cigarette provides 50% air dilution. Cigarettes made in this way are designated as samples 11, 12, 13. C-5, respectively, the sample of filler material from which the cigarette is manufactured kazh- yes

The filler material used to produce the tobacco rod is presented in the form of straw, cut at a frequency of 32 cuts per inch. The starting filler material consists of a mixture of 31% Barley tobacco, nicotine content 5%, 20% tobacco flue-drying, nicotine content 3.5% , 31% of the regenerated tobacco material, a nicotine content of 0.5% and 18% of the eastern tobacco mixture, a nicotine content of 0.9, the mixture is treated with a water-glycerin g humidifier and aroma-gas is introduced into it.

Four batches of sliced executive mixture are provided, each batch weighing 3120 g. “The first batch is treated with 40 g of levulinic acid. The second batch is treated with 120 g of levulinic acid. The third batch is treated with 200 g of levulinic acid. The fourth batch is not processed with {levulinic acid and is used for comparison.

The 1-nicotine lulubate seasoning is applied to the chopped filler by spraying using a hand sprayer in the form of a 1: 1 mixture of water and seasoning. The amount of water in the mixture of water and seasoning is such that the final moisture content of the straw is 15%.

Each of the four batches is individually placed in sealed plastic bags and stored for 2 days at 70 ° F. Then, four batches are individually mixed with 880 g of a chopped filling mixture of 35 parts of Barley's foamed tobacco 4% nicotine and 65 parts of foamed flue-drying tobacco nicotine content 4%. Foamed chopped filler is added to each batch using a mixing drum to obtain a well-mixed mixture having a moisture content of 12-13%.

The resulting mixture gives for the first batch of filler material about 1% of applied levulinic acid (in terms of the conditioned weight of the filler), which is indicated as sample t1. The resulting mixture from the second batch of filler has about 3% applied levulinic acid (in terms of air-conditioned mass, fill

l), which is designated as sample 12 "The resulting mixture from the third batch of filler has about 5% applied levulinic acid (in terms of the conditioned mass of the filler), which is designated as sample 13" The resulting mixture from the fourth batch of filler not treated with levulin acid, used for comparative purposes and designated as sample C-5,

Various cigarettes were used for smoking. Data regarding (i) tar formation, nicotine and carbon monoxide, (ii) the ratio of the resin / / nicotine, (iii) the nicotine content of the cigarette, and (iv) the number of puffs,

The data in Table 4 shows that the various cigarettes according to the invention, having a highly nicotine-filled filler (ie, more than 2.5% of the total nicotine in the mixture), produce tar, nicotine, and carbon monoxide, comparable to a control cigarette. Different cigarettes also provide comparable tar / nicotine ratios and puff numbers. However, cigarettes according to the invention (samples 11-13, containing levulinic acid as a seasoning) provide a lower pH of the mainstream smoke for puffing and, on average, when compared with the control (sample C-5, which does not contain levulinic acid),

The organoleptic evaluation of the samples shows that the cigarettes according to the invention provide a relaxed smoking character, while the control sample is very sharp. The softness of samples 12 and 13 is considered comparable. Cigarettes according to the invention provide a good tobacco taste, strength and satisfaction when smoking. The control sample is very strong and its effect is perceived as overly strong without creating satisfaction.

Example 5. Cigarettes containing different amounts of levulinic acid are prepared using the following procedure. Cigarettes with a length of about 84 mm and a circumference of 24.85 mm have tobacco rods 57 mm long and filters 27 mm long. The tobacco rod includes the loading of chopped tobacco weighing about

The 0.82 g contained in oOrciphering her cigarette paper, which is supplied commercially by the brand of cigarette paper 856. And the cutters are manufactured using traditional cellulose acetate filter technology (2.7 denier per thread, totaling 48,000 denier), and is air permeable in paper wrap with Coresta porosity of about 26000 cm / min. The tobacco rod and filter are joined by ends and fastened using substantially impermeable air with mouthpiece paper. Mouth paper is attached with glue filter and an adjacent portion of the tobacco rod. Mouthpiece material surrounds the filter along the entire length and goes to 4 mm on the tobacco rod. The cigarettes described in this way are produced on an experimental-industrial whiteboard rebuilding machine. The cigarettes made in this way are designated as samples 14, 15, 16 and C-6, respectively, as in the filling material from which each cigarette is made.

Filling materials used to make tobacco rods for samples 14, 15, 16 and C are identical to the filling materials described for samples 11, 12, 13 and C-5, respectively.

Different cigarettes were used for smoking under conditions defined by the FTC0 standards. Data on (i) the content of nicotine in each mixture; (ii) tar and nicotine contents, (lii) tar / nicotine ratios, (iv) puff numbers, and (v) the pH of the main stream aerosol for each sample is given in Table 5.

The data in Table 5 show that various cigarettes according to the invention, which have the benefit of okonikotinopropanol filler (t e and more than 2.57 total nicotine in the mixture) give

production of tar, nicotine and carbon monoxide comparable to a control cigarette. Different cigarettes also give comparable gumola / nicotine ratios and puff numbers. However, cigarettes according to the invention (14-16 are formed, the content of levulinic acid as a seasoning) provides low pH smoke main flow on a puff and on average

when compared with the control (sample C-6, which contains levulinic acid).

The organoleptic evaluation of the samples shows that the cigarettes according to the invention provide a relaxed smoking character, then the kchk control sample is very sharp, the softness of samples 15 and 16 is considered comparable. Cigarettes according to the invention provide a good tobacco taste, strength and satisfaction when smoking. The control sample is very strong and its effect is perceived to be excessively strong.
