Abstract
Description
An explosive flavoring agent and its preparation method, and a cigarette.
[0001] This application claims priority to Chinese Patent Application No. CN202411800446.2, filed on December 9, 2024, the contents of which are incorporated herein by reference in their entirety. Technical Field
[0002] This invention belongs to the field of cigarette technology, specifically relating to an explosive flavoring agent and its preparation method, and a cigarette. Background Technology
[0003] "Break capsules" are small liquid beads embedded in tobacco filters. They can encapsulate different types of flavoring liquids. When smokers squeeze them during smoking, the liquid inside the capsule flows out, enriching the flavor of the cigarette. The soft sound when the capsule breaks and the unique feel provide smokers with a better user experience.
[0004] Currently, flavor capsules have become a new way to enhance the aroma and retain the flavor of cigarettes. Encapsulating flavorings in a solid form can effectively preserve the concentration and purity of aromatic substances and reduce the volatilization of flavorings. However, current flavor capsules must be popped by the smoker with their fingers, teeth, or tools, which is not very convenient for smokers. Summary of the Invention
[0005] In view of this, the purpose of this invention is to provide an explosive flavoring agent and its preparation method, as well as a cigarette. The explosive flavoring agent can spontaneously explode upon heating when inhaled by a smoker, releasing the flavorings and enriching the flavor of the smoke.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] In a first aspect, the present invention provides an explosive fragrance, the raw materials for which, by mass fraction, include 0-8% excipients, 0.5-5.0% carbon dioxide gas, and the remainder being fragrance.
[0008] Preferably, the raw materials for preparing the explosive fragrance include 0-5.5% excipients, 0.5-2.5% carbon dioxide gas, and the remainder is fragrance.
[0009] Preferably, the carbon dioxide gas is added to the raw material preparation system under a pressure of 3 to 5 MPa.
[0010] Preferably, the excipients are selected from citric acid and / or sodium carboxymethyl cellulose.
[0011] Preferably, the amount of citric acid added is 0 to 3.5% of the flavoring mass.
[0012] Preferably, the amount of sodium carboxymethyl cellulose added is 0-2% of the flavoring mass.
[0013] Preferably, the flavoring is a tobacco flavoring.
[0014] Secondly, the present invention provides a method for preparing the above-described explosive fragrance, comprising the following steps:
[0015] The fragrance solution and optional excipients are heated at 120-180°C and mixed evenly to obtain a mixed solution. Carbon dioxide gas is introduced into the mixed solution in a closed environment at 3-5 MPa. The resulting mixed slurry is cooled and molded to obtain a burst-type fragrance.
[0016] Preferably, the fragrance solution is subjected to vacuum dehydration treatment.
[0017] Preferably, the water content of the fragrance solution is 1-3 wt%.
[0018] Preferably, the introduction of carbon dioxide gas is carried out under stirring conditions; the time for introducing carbon dioxide gas is 10 to 20 minutes.
[0019] Preferably, the cooling to room temperature is achieved.
[0020] Preferably, the cooling and forming process further includes cutting and sieving steps.
[0021] Thirdly, the present invention provides a cigarette containing the explosive flavoring involved in the above-mentioned technical solution.
[0022] Preferably, the amount of the explosive flavoring added accounts for 0.1% to 8% of the mass of the cigarette tobacco.
[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0024] This invention provides a bursting flavoring agent, similar to a "capsule," whose raw materials include excipients, flavoring agents, and carbon dioxide gas. In the preparation process of the bursting flavoring agent, carbon dioxide gas is injected into a mixture of flavoring solution and optional excipients under high pressure (3-5 MPa). After cooling and solidification, a solid flavoring block is obtained. This flavoring block contains carbon dioxide gas bubbles with a certain pressure (above atmospheric pressure). When this flavoring block is added to cigarettes, it does not need to be popped with fingers, teeth, or tools. During inhalation, the flavoring agent and excipients in the flavoring block dissolve under heating, and the high-pressure carbon dioxide bubbles inside are rapidly released, producing a popping sound similar to that of clove cigarettes. Simultaneously, the flavoring agent enters the smoker's mouth with the smoke, enriching the flavor and providing a more unique smoking experience. Detailed Implementation
[0025] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0026] In view of the problem that the "flavor capsules" in cigarettes must be popped by the smoker with their fingers, teeth or tools, which is not convenient for smokers, the present invention provides a popping flavoring that can be popped on its own during smoking. The raw materials for its preparation include, by mass fraction, 0-8% excipients, 0.5-5.0% carbon dioxide gas, and the balance being flavoring; preferably, it includes 0-5.5% excipients, 0.5-2.5% carbon dioxide gas, and the balance being flavoring.
[0027] In this invention, the flavoring can be any kind of tobacco flavoring, and can be a single flavoring or a compound flavoring with multiple components. Specifically, the flavoring can be selected from any one or more of the following: chocolate flavoring, milk flavoring, fruit flavoring, nut flavoring, wood flavoring, floral flavoring, spice flavoring, honey flavoring, paste flavoring, bean flavoring, bread flavoring, caramel flavoring, phenolic flavoring, smoked flavoring, or alcohol flavoring.
[0028] In this invention, the excipients may or may not be added. Their addition can increase the glass transition temperature of the explosive fragrance and improve its stability. The excipients are generally selected from citric acid and / or sodium carboxymethyl cellulose. Specifically, the amount of citric acid added is 0-3.5% of the fragrance mass, preferably 0.5-2.5%; the amount of sodium carboxymethyl cellulose added is 0-2% of the fragrance mass, preferably 0.5-1.5%.
[0029] In this invention, the carbon dioxide gas is added to the raw material system at a pressure of 3 to 5 MPa, so that the carbon dioxide bubbles in the prepared explosive fragrance have a pressure higher than that of atmospheric pressure, thereby achieving the effect of self-explosion.
[0030] In this invention, carbon dioxide gas was chosen because it is a safe gas permitted for use in food, is readily available, inexpensive, has a certain degree of solubility in water, and will not chemically react with sugar, flavorings, colorings, etc. during processing.
[0031] The present invention also provides a method for preparing the above-mentioned explosive fragrance, comprising the following steps:
[0032] The fragrance solution and optional excipients are heated at 120-180°C and mixed evenly to obtain a mixed solution. Carbon dioxide gas is introduced into the mixed solution in a closed environment at 3-5 MPa. The resulting mixed slurry is cooled and molded to obtain a burst-type fragrance.
[0033] In this invention, the fragrance solution needs to be vacuum dehydrated to form a fragrance concentrate with a water content of 1-3%, preferably 1.5-2.5%.
[0034] According to the present invention, the fragrance solution and optional excipients are first heated at 120–180°C, preferably 150–160°C, and mixed evenly to obtain a mixed solution. Then, carbon dioxide gas is introduced into the mixed solution under a high pressure of 3–5 MPa, and the slurry is mixed and stirred in a high-pressure carbon dioxide environment for 10–20 min, preferably 15–18 min. During the mixing and stirring, the high-pressure carbon dioxide gas completely penetrates into the slurry, resulting in the formation of many tiny carbon dioxide bubbles in the slurry.
[0035] Then, according to the present invention, the slurry is cooled to room temperature in a carbon dioxide environment to obtain the molded explosive fragrance. The room temperature is "10-30°C", preferably "15-25°C".
[0036] To facilitate subsequent applications, after cooling, the obtained explosive spice is cut into small pieces and sieved. Generally, the diameter of the cut explosive spice pieces is 1-3 mm, preferably 1.5-2 mm. At this point, these spice pieces still contain many tiny carbon dioxide bubbles.
[0037] The present invention also provides a cigarette containing the explosive flavoring described above.
[0038] Specifically, the present invention mixes the explosive flavoring involved in the above technical solution with cigarette tobacco and rolls it into a cigarette stick, which can be a traditional cigarette or a heated cigarette.
[0039] In some embodiments of the present invention, the amount of the explosive flavoring added accounts for 0.1 to 8% of the mass of the cigarette tobacco, preferably 0.5 to 5%.
[0040] In summary, this invention involves injecting carbon dioxide gas into a mixture of flavoring solution and optional excipients under high pressure (3-5 MPa). After cooling and solidification, a solid flavoring block is obtained. This flavoring block contains carbon dioxide bubbles at a certain pressure (above atmospheric pressure). When this flavoring block is added to cigarettes, it does not require popping with fingers, teeth, or tools. During inhalation, the flavoring and excipients in the block dissolve under heating, and the high-pressure carbon dioxide bubbles inside are rapidly released, producing a popping sound similar to that of clove cigarettes. Simultaneously, the flavoring enters the smoker's mouth with the smoke, enriching the flavor and providing a more unique smoking experience.
