Description

Scented pearls and cigarette filter.

Technical field

The present invention relates to a cigarette filter containing a flavor pearl.

Prior art

Flavors added to cut tobacco include a primary flavoring that is a conditioning sauce, and a secondary flavoring that is a solution of flavoring essences. The components of the secondary flavor are relatively highly volatile, and are susceptible to pyrolysis. Therefore, the secondary flavoring contained in a cigarette evaporates during storage, which results in a decrease in taste during smoking. In addition, in a cigarette that has a charcoal filter, the secondary flavor migrates and is adsorbed in the charcoal filter, which results in an additional decrease in flavor. The charcoal filter having the second adsorbed flavor has decreased the ability to remove smoke components from the mainstream of tobacco.

Japanese Patent No. 2709077 describes the microencapsulation of a secondary flavoring with a natural polysaccharide, and the addition of the microcapsules to a tobacco filter by the so-called cavity filling procedure. As the flavor is encapsulated in the microcapsules composed of the natural polysaccharide, it will not cause migration or evaporation of the flavor during storage, and thus will not impair the ability of the charcoal filter to remove the mainstream smoke components of tobacco.

However, in microcapsules, the taste can be tested only by crushing or squeezing them with your fingers (application of external force) when smoking. The application of external force is annoying. In addition, the taste released by the application of external force will not spread evenly over the filter, resulting in an erratic taste during smoking.

Description of the invention

Accordingly, the present invention is intended to provide a cigarette filter that can suppress the evaporation and migration of a flavor during the non-smoking stages, and that allows a stable taste tasting during the smoking stages without requiring the application of force external

According to one aspect of the present invention, a cigarette filter is provided as defined in the claim.

Best way to carry out the invention

Various embodiments of the present invention will be described below with reference to the drawings. Similar elements are designated by reference numbers throughout the drawings.

A flavor pearl used in the present invention includes a particulate carrier, a glucan film supported by the particulate carrier and a flavoring. The flavor is supported by the flavor pearl so that the flavor release of the flavor is suppressed by the glucan film, although the flavor is released with the glucan film at least partially dissolved when the glucan film contacts the smoke of mainstream of tobacco.

According to a first embodiment of the present invention, the glucan film contains a flavoring, and directly covers the surface of the particulate vehicle. The flavor pearl according to the first embodiment includes the particulate vehicle, and the glucan film that covers the surface of the particulate vehicle and which contains the flavoring.

According to a second embodiment of the present invention, the flavor is a solid flavor that directly covers the surface of the particulate vehicle, and the glucan film covers the solid flavor film. The flavor pearls according to the second embodiment each include the particulate vehicle, the menthol film that covers the surface of the vehicle, and the glucan film that covers the surface of the menthol film.

The particulate vehicle used in the present invention is composed of calcium carbonate particles or coffee beans. As the particulate vehicle, particles having an average particle size of 75 µm to 2000 µm, for example 75 µm to 350 µm, can be suitably used.

The glucan film is composed of, for example, pululane, maltodextrin or hydroxypropyl cellulose and is soluble in water.

The flavoring can be one for food or tobacco use. Examples of such flavors include lavender, cinnamon, cardamom, celery, clove, husk, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon, orange, mint, cinnamon, caraway, cognac, jasmine, Chamomile, menthol, cassia, ylang ylang, sage, spearmint, fennel, bell pepper, gin, anise, coriander and coffee essential oils.

FIG. 1 is an elongated schematic cross-sectional view of a flavor pearl 10 according to the first embodiment of the present invention. The flavor pearl 10 includes a particulate vehicle (core) 12, the surface of which is covered by a glucan film 14. The glucan film 14 contains the flavor.

The glucan film 14 containing the flavoring can be formed from an aqueous solution or dispersion of the flavoring and the glucan. In the aqueous solution or dispersion, the flavor is preferably used in an amount corresponding to 20% or less (although more than 0%) of the weight of the glucan. The glucan film 14 is not particularly limited in its thickness. However, in view of the ability to release flavor during smoking, the glucan film is preferably formed with glucan in an amount corresponding to 0.25% to 5% of the weight of the finished flavor pearl.

The flavor pearl according to the first embodiment can be produced, for example, by the following method. Namely, particulate vehicles composed of calcium carbonate or the like are loaded into a fluidized bed granulation dryer, and an aqueous solution or dispersion of glucan containing the flavoring is sprayed continuously or intermittently on the surface of the vehicles. particulate while blowing, for example, hot air at 80 ° C or less in the granulation dryer, followed by drying. In this case, the vegetables are cooled immediately depending on the type of flavor or the composition of the glucan solution. In this way, a glucan film containing the flavor is formed on the surface of the particulate vehicle.

In the flavor pearl according to the first embodiment, as the flavor is contained in the glucan film, which has a low gas permeability, evaporation and degradation of the flavor during storage can be suppressed. Only after contact with mainstream tobacco smoke during smoking, the glucan film is partially dissolved primarily by highly polar components (e.g. water), in mainstream tobacco smoke, and releases the flavoring component that is dispersed in the mainstream smoke, thus allowing the stable tasting of the flavor of the flavor. The flavor pearl of the present does not need the application of external force to test the taste as it is done in the case of microcapsules.

FIG. 2 is an elongated schematic cross-sectional view of a flavor pearl 20 according to the second embodiment of the present invention. In the flavor pearl 20, the entire surface of a particulate vehicle (core) 22 is covered by a film 24 of a solid flavoring such as menthol, and the entire surface of the solid flavoring film 24 is covered by a film of glucan 26.

As described later, the solid flavoring film 24 can be formed by finely spraying crystals of the solid flavoring such as menthol, mixing the resulting fine particles of solid flavoring with the particulate vehicle 12, thereby adhering the fine particles of solid flavoring to the vehicle in particles 22, melting the fine particles of solid flavor in the particulate vehicle 22 by heating, and then recrystallizing the solid flavor by cooling. To prevent the solid flavoring such as menthol from growing on columnar crystals during cooling, it is preferred that a crystal growth inhibitor such as a fatty acid, glycerol or propylene glycol, be added to the solid flavoring. The crystal growth inhibitor can be used in an amount corresponding to 0.1 to 1.0% of the weight of the solid flavor such as menthol. The solid flavor film 14 may contain a flavor other than the solid flavor.

The solid flavoring film 24 is not particularly limited in its thickness. However, the solid flavoring film 24 is preferably formed with the solid flavoring in an amount corresponding to 1 to 20% of the weight of the finished flavor pearl.

The glucan film 26 can be formed from an aqueous solution or dispersion of glucan. The glucan film 26 is not particularly limited in its thickness. However, in view of the ability to accommodate the flavor of the solid flavoring at non-smoking stages and the ability to release menthol during smoking, the glucan film 26 is preferably formed with glucan in an amount corresponding to 0.25% at 5% of the weight of the finished flavor pearl.

The flavor pearl according to the second embodiment can be produced by, for example, the following method. Namely, the particles and fine particles vehicles of the solid flavoring crystals, and if necessary, the crystal growth inhibitor and other flavoring are mixed and heated in a horizontal mixer with helical tape. During the initial stages of mixing, the fine particles of solid flavoring crystals adhered to the surfaces of particulate vehicles, and fine particles of solid flavoring crystals begin melting when the heating temperature reaches the melting point of the solid flavor (for example, about 42 ° C for menthol). Stirring and mixing are further continued by thus uniformly applying the molten solid flavor to the surfaces of the particulate vehicles. After mixing under heating, the particulate vehicles are cooled immediately by, for example, cooling the can body of the horizontal mixer with helical tape, or by blowing cold air into the horizontal mixer with helical tape. The molten solid flavor is recrystallized by the cooling treatment to cover the surfaces of the particulate vehicles like a film. The particulate vehicles covered with the solid flavoring films are loaded into a fluidized bed granulation dryer, and an aqueous solution or dispersion of glucan is intermittently sprayed into the particulate vehicles while blowing, for example, hot air at 40 ° C or less in the granulation dryer, followed by cooling. In this way, a glucan film is formed on the surface of the solid flavoring film formed on the surface of the particulate vehicle.

Alternatively, the flavor pearl according to the second embodiment can also be produced by forming a solid flavoring film on the surfaces of the particulate vehicles as described above, and by spraying an aqueous solution or dispersion of glucan in the vehicles. in particles having solid flavoring films in a horizontal mixer with helical belt or a roller granulator, thus covering the solid flavoring film with the glucan film, followed by cooling.

In the flavor pearl according to the second embodiment, as the solid flavoring film formed on the surface of the particulate vehicle is covered by the glucan film, which has a low gas permeability, the menthol is prevented from evaporating or adhering to the charcoal during storage under normal conditions. When the glucan film contacts the hydrophilic components such as water contained in the mainstream smoke emitted during cigarette smoking, the glucan film partially deforms and dissolves, whereby the flavor is released from the flavoring film underlying solid and can be tested. The flavor pearl of the present invention does not need the application of external force to test the taste as is done in the case of microcapsules.

The present invention will be further described below with reference to specific Examples, although the present invention should not be limited to these Examples.

Example 1

2% by weight of a coffee oil was added to a previously prepared aqueous dispersion of pululane containing 10% by weight of pululane. The mixture was vigorously stirred in an emulsifier (emulsifier rotation speed of 2500 rpm), thus preparing a dispersion of flavoring. On the other hand, 100 g of calcium carbonate particles having an average particle size of 250 µm were loaded in a fluidized bed granulation dryer, and immediately the flavor dispersion was sprayed intermittently into the particles (cycles repeated that each consisted of spraying for 1 minute and stopping for 30 minutes), while blowing hot air at 75 ° C in the dryer at a flow rate of 0.6 m / second, thus spraying 10 g of the total flavor dispersion on the surfaces of the calcium carbonate particles, followed by drying. Then, the inside of the fluidized bed was immediately cooled to room temperature, thereby obtaining desired flavor pearls.

Example 2

100 g of calcium carbonate particles having an average particle size of 250 µm were loaded in a fluidized bed granulation dryer, and an aqueous flavoring mixture solution containing 1% by weight of a tobacco flavoring and 9% by weight of pululane, added with vanillin, was continuously sprayed on the particles, while hot air was blown at 30 ° C in the dryer at a flow rate of 1.0 m / second, thus spraying 5 g of the solution of Aqueous mixture on the surfaces of the calcium carbonate particles, followed by drying. Then, the temperature of the hot air was immediately lowered to room temperature, and the particles were cooled to a flow rate of 0.4 m / second, thereby obtaining desired flavor pearls.

Example 3

1% by weight of coffee oil and 0.5% by weight of lecithin were added to a previously prepared aqueous dispersion of pululane containing 10% by weight of pululane. The mixture was vigorously stirred in an emulsifier (emulsifier rotation speed of 7500 rpm, 15 minutes), thus preparing a flavor dispersion. On the other hand, 300 g of ground coffee bean particles having a particle size of 250 µm to 1.4 mm were loaded in a rotary fluidized bed granulation dryer (SFC-MINI, manufactured by Freund Corporation), and the perforated disc at the bottom and the blades of the mixer to prevent the formation of lumps were rotated at approximately 500 rpm and approximately 400 rpm, respectively, while blowing hot air at 75 ° C in the dryer at a flow rate of 0.6 m / second , thus forming a fluidized bed of ground coffee particles. The flavor dispersion maintained at 40 ° C was sprayed continuously in the fluidized bed, thus spraying 90 g of the total flavor dispersion on the surface of the ground coffee particles, followed by drying. Then, the temperature of the hot air was immediately lowered to room temperature, and the particles were cooled to a flow rate of 0.4 m / second, thereby obtaining desired flavor pearls.

Example 4

Cigarettes with filter were made as shown in FIG. 3 using the flavor pearls obtained in Examples 1 to 3, respectively. In each case, the amount of flavor pearls added to filter section 342 was a maximum of 100 mg for 10 mm of filter length. These cigarettes did not emit the flavor of the flavor during storage. However, the taste could be tasted stably when these cigarettes were smoked.

Example 5

90 g of calcium carbonate particles having an average particle size of approximately 200 µm, 10 g of fine menthol powder, which had been obtained by spraying menthol crystals, and 0.5 g of glycerol in a mixer were charged Horizontal helical tape. The contents were heated to 40 ° C while stirring, and mixed further for 5 minutes. The menthol melted completely, and the calcium carbonate particles were allowed to adhere and coat. Subsequently, cold air was blown at 15 ° C in the horizontal mixer with helical belt to cool the particles. Thus, calcium carbonate particles were obtained whose surfaces were each coated with menthol crystal film. The calcium carbonate particles that had the menthol films were loaded into a fluidized bed granulator, and immediately a 5% by weight aqueous solution of pululane was sprayed intermittently while blowing hot air at 40 ° C in the granulator at a flow rate of 1.0 m / second, thus spraying a total of 15 g of the aqueous pululane solution in the calcium carbonate particles. Then, the particles were cooled to 25 ° C, thereby obtaining desired menthol flavor beads.

Example 6

Cigarettes with filters as shown in FIG. 3 were made using the menthol flavored pearls obtained in Example 5. The amount of the menthol flavored pearls added to filter section 342 was 3 mg in terms of menthol per cigarette. Cigarettes did not emit the menthol flavor under normal storage conditions. However, the menthol flavor could be tasted stably when these cigarettes were smoked.
