Description

Cross-Reference to Related Applications

The present disclosure claims priority to Chinese Patent Application No. 202011163680.0 , entitled "Tobacco Product and Plant-Flavored Filter Stick Thereof, and Preparation Method Therefor", filed with the Chinese Patent Office on October 27, 2020, the contents of which are incorporated herein by reference in entirety.

Technical Field

The present disclosure relates to the field of cigarette, and particularly to a tobacco product and a plant-flavored filter stick thereof, and a preparation method therefor.

Background Art

With the increasing call for smoke banning internationally and as cigarette consumers increasingly value their own health, low-tar and low-harm cigarettes have become the new normal in the tobacco market. However, the reduction of tar and harm inevitably leads to the loss of cigarette aroma and a deterioration in comfort. While adding flavor to the cigarette can support and supplement cigarette aroma, remove and cover up miscellaneous gases, thereby not only reducing the irritation of cigarettes, but also endowing the cigarette products with elegant characteristic aroma, such that the personalized style of cigarette products is highlighted. The development and application of adding flavor to the cigarette is becoming one of the key technologies to maintain the aroma of cigarettes in the work of reducing harm and tar.
Currently, cigarette aroma addition mainly includes two methods: cigarette component aroma addition and cigarette accessory aroma addition. Because the amount of aroma added to cigarettes by the cigarette component aroma addition method is limited, and cigarette accessory aroma addition can make up for the shortcomings of insufficient aroma addition amount by the cigarette component aroma addition, most of the existing research and development of cigarettes are carried out towards the method of cigarette accessory aroma addition.
Cigarette accessory aroma addition is mainly achieved through the addition of aroma to cigarette paper, liner paper, tipping paper, and filter stick. However, cigarette paper itself burns, liner paper and tipping paper have defects like limitations on aroma addition amount and short aroma retention time. Therefore, cigarette accessory aroma addition mainly is aroma addition to filter stick. Aroma addition to cigarette filter stick mainly includes aroma addition by bubbles, tows and particles. Aroma addition by bubbles has high cost and is limited by the addition of oily flavor substances. Aroma addition by tows and particles have problems such as low adsorption of flavor substances and uneven aroma addition.

The basic principles defined in the following description of the present disclosure can be applied to other embodiments, variation solutions, improvement solutions, equivalent solutions, and other technical solutions that do not depart from the spirit and scope of the present disclosure.
It should be understood by those skilled in the art that in the present disclosure, the terms "vertical", "transverse", "up", "low", "forward", "backward", "left", "right", "upright", "horizontal", "top", "bottom", "inner", "outer" and other directions or positional relationships indicate the directions or positional relationships shown in the drawings, which are only for convenience of describing the present disclosure and simplification of description, and do not indicate or imply that the device or component mentioned must be in a specific direction, or structured or operated in a specific direction, thus the abovementioned terms should not be interpreted as limitations on the present disclosure.
With reference to Fig. 1 to Fig. 2 of the specification, a tobacco product according to the embodiment of the present disclosure will be described in detail below, wherein the tobacco product can be a tobacco product that is heated and burned to form smoke by volatilizing aerosol, or a tobacco product that is heat-not-burn to form smoke by volatilizing aerosol. The present disclosure is not limited in this aspect.
The tobacco product of the present disclosure can include a smoking segment 10, a cooling segment 20 and a filter segment 30. The smoking segment 10 and the filter segment 30 can be respectively installed at two ends of the cooling segment 20, so that the smoking segment 10 can form smoke by volatilizing aerosol, after the smoking segment 10 is heated and the user smokes the filter segment 30.
The cooling segment 20 can reduce the temperature of the smoke formed by volatilization of the heated smoking segment 10 when the user smokes the filter segment 30, so as to prevent the user's mouth from being scalded.
The filter segment 30 can be implemented as a plant-flavored filter stick, wherein the plant-flavored filter stick can be configured as having gas hole passing through both ends of the filter segment 30, and the filter segment 30 can include:

It is worth mentioning that the plant powder can include but is not limited to cultivated plants and wild plants with aroma. For example, it may include, but is not limited to, tangerine peel, licorice, lavender, basil, mint, rosemary, purple perilla and the like.
More preferably, the filter segment 30 can also include a predetermined amount of essence solidified on the plant-flavored filter stick. The essence can include at least one of water-soluble essence, oil-soluble essence and microencapsulated essence. Specifically, the essence can be implemented as one or more of tangerine peel essence, sweet orange essence, mint essence, jasmine essence, passion fruit essence, amyl acetate, ionone, phenylethyl alcohol, eugenol and perillartine.
Preferably, the solvent of the oil-soluble essence can preferably be medium-chain triglyceride, glycerol triacetate, triethyl citrate and so on, such that the adsorption capacity of the essence is increased.
More preferably, the cooling segment 20 can be implemented as a plant element with a porous structure penetrating through the cooling segment 20. Therefore, after the smoking segment 10 is heated, the aroma emitted by the essence on the plant-flavored filter stick through the holes on the plant element when heated can be mixed in the aerosol formed by volatilization of the smoking segment 10, thereby achieving the uniform diffusion of aroma.
The plant-flavored filter stick itself is composed of fragrant plant raw material powder, and therefore, the plant-flavored filter stick can volatilize sufficient aroma after being heated, so as to make up for the lack of aroma of tobacco products in the prior art.
According to some embodiments of the present disclosure, the present disclosure provides a preparation method of the plant-flavored filter stick, the preparation method of the plant-flavored filter stick can include the following steps:

(S1) mixing 4-5 parts by weight of plant raw material powder with aroma, 4-6 parts by weight of smoking agent, 4-6 parts by weight of adhesive and 4-6 parts by weight of water, and making the mixture into block-shaped wet material;
(S2) squeezing the wet material;
(S3) cutting and separating the squeezed wet material;
(S4) spraying the aroma evenly onto the cut and separated wet material to obtain the semi-processed flavored wet material;
(S5) molding the semi-processed plant-flavored filter stick by extrusion molding; and
(S6) drying the semi-processed plant-flavored filter stick to obtain the plant-flavored filter stick.

Preferably, the step (S1) can be implemented as stirring and mixing for 1 h in a kneading device under the condition of 50 r/min, so as to make a block-shaped wet material to be squeezed.
Preferably, drying the semi-processed plant-flavored filter stick in the step (S6) may be implemented as follows: at a temperature of 100-110°C, drying the semi-processed plant-flavored filter stick until the water content is 8-10% by weight. It is worth mentioning that when the moisture in the plant-flavored filter stick is kept at 8-10% by weight, it can help release the aroma of the plant raw material powder with aroma in the plant-flavored filter stick.
Preferably, the preparation method of the plant-flavored filter stick can include the following step:
(S7) before drying the semi-processed plant-flavored filter stick, cutting the semi-processed plant-flavored filter stick into a predetermined length.
It is worth mentioning that, in the step (S3) of the preparation method of the plant-flavored filter stick, the squeezed wet material can be cut into filaments. In this way, the essence sprayed on the plant-flavored filter stick subsequently can be more uniform.
In addition, in the step (S2), squeezing the wet material can make the formed wet material more compact, which is beneficial for the cut and separated wet material to adsorb more essence.
Preferably, the preparation method of the plant-flavored filter stick can include the following step:
(S8) after spraying the essence onto the cut and separated wet material to form the semi-processed flavored wet material, placing the semi-processed flavored wet material in an airtight environment at 23±2°C and a humidity of 60±5% for a predetermined period of time, so that the semi-processed product of the flavored wet material can fully absorb the sprayed essence.

Example 1

The block-shaped wet material was made by mixing 4.5 parts by weight of plant raw material powder with aroma, 5 parts by weight of smoking agent, 5 parts by weight of adhesive and 5 parts by weight of water, meanwhile the plant-flavored filter stick was made according to the above-mentioned preparation method, wherein the essence can be peppermint oil to prepare the plant-flavored filter stick.

Comparative Example 1

The filter stick was made according to the method of prior art. After soaking the filter stick directly in the essence (peppermint oil) for 1 h, the essence on the surface was wiped off to obtain an essence-soaked filter stick.

After the filter sticks in Example 1 and Comparative Example were placed at 22°C and 60% relative humidity for different periods of time, the aroma retention capacity of the two filter sticks was compared. The aroma components in the two samples can be identified by using SPME-GC/MS. GC internal standard method can be used for content determination, in which the chromatographic column can be HP-5 capillary column (30 m×0.32 mm×0.25 µm), with 1-octanol as the internal standard. The specific results are shown in the table below. It can be seen from the following Table 1 that the plant-flavored filter stick of Example 1 has a much greater retention capacity for aroma substances than that of the Comparative Example.
