Description

Technical Field

[0001] The present invention relates to a collapsible seamless capsule, a filter including the same, and a smoking device.

Background Art

[0002] Conventionally, capsules have been widely used in fields such as pharmaceuticals, cosmetics, and health foods. In recent years, their applications have expanded, and there has been a demand not only for techniques to increase the strength of capsule membranes to make them less likely to break, but also for techniques to make them more likely to break. For example, a capsule containing a fragrance or the like is embedded in a tobacco filter, and by breaking the capsule during smoking or the like, there is an increasing demand for capsules that can enjoy the fragrance of the capsule contents, the cracking sound, and the feel when the capsule is broken. There is a need for a capsule that can be easily collapsed by applying pressure with a finger during smoking or the like. For example, Patent Document 1 discloses a collapsible capsule in which a hydrophilic colloid is contained in a shell. It is stated that the capsule can maintain its collapsibility even when exposed to moisture brought about by a smoker in a smoking device.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In recent years, the demand for capsules with strong scents and stimuli has been increasing, and an enhancement of the scent at the time of capsule disintegration is desired. The strength of the scent at the time of capsule disintegration correlates with the amount of contents such as fragrances released at the time of disintegration. Therefore, the present inventor has tried to enhance the scent at the time of capsule disintegration by increasing the proportion of oily components such as fragrances in the capsule contents. However, oily components such as fragrances are highly volatile, and when they are contained in a high content, there is a problem that the contents such as oily components volatilize from the capsule film over time, making it difficult to ensure the storage stability of the contents. For example, when increasing the content of the fragrance in the contents with the film formulation of Patent Document 1, the volatilization amount of the fragrance during storage of the capsule increases, so it has been difficult to hold the fragrance component at a high concentration in the capsule. Furthermore, when the capsule film is thickened to reduce the volatilization amount of the contents, the breaking strength of the capsule increases, and there is a problem that it is difficult to disintegrate the capsule by applying pressure with a finger, or the capsule deforms without cracking. In particular, in a commonly used capsule in which gelatin and glycerin are mixed as in Patent Document 1, there is a problem that the breaking strength of the capsule becomes high and it is not easy to disintegrate the capsule to release the contents. Also, it is conceivable to thicken the film while suppressing an increase in breaking strength by increasing the content rate of the gelling agent component in the capsule film. In this case, however, the film component becomes highly viscous, making capsule production difficult.

[0005] There is a demand for a capsule that can suppress the volatilization of highly volatile capsule contents from the capsule film and has the ability to disintegrate the capsule.

[0015] <Capsule> The capsule of the present invention is a collapsible seamless capsule.

[0016] FIG. 1 shows a schematic diagram of an embodiment of a collapsible capsule. As shown in FIG. 1, the capsule 3 is a seamless capsule having a content 1 and a capsule film 2. The content 1 is encapsulated in the capsule film 2. The content 1 of the capsule contains an oily component such as a fragrance, and the capsule film 2 contains polysaccharides. The capsule 3 is collapsible, and by applying pressure with a finger, the capsule film 2 ruptures and the content 1 is released to the outside of the capsule. Specifically, after the capsule 3 is encapsulated in a smoking device (for example, inside a filter in a smoking device), during use, the capsule film 2 can be broken by applying pressure with a finger. When the capsule film 2 is broken, the fragrance etc. of the content 1 is released, and the fragrance can be enjoyed.

[0017] In this specification, "collapsible" means that the capsule film can collapse due to external pressure and release the content, preferably, the capsule film can collapse and the content can be released by a smoker applying pressure with a finger. In the present invention, the breaking strength per capsule diameter is 3 to 8 N / mm. If it exceeds 8 N / mm, it becomes difficult to crush the capsule with a finger, which is not preferable. If it is less than 3 N / mm, the capsule is easily cracked and the handleability deteriorates. In particular, the capsule may crack during encapsulation in a smoking device or a filter or during transportation. In one embodiment, the breaking strength per capsule diameter is preferably 3.5 to 8 N / mm, more preferably 3.5 to 7.5 N / mm, and even more preferably 4 to 7 N / mm. When within such a range, it can be more easily broken when an appropriate force is applied with a finger, and the feeling of cracking is good. In one embodiment, the breaking strength per capsule diameter is 5 to 8 N / mm. When within such a range, the capsule is difficult to break during storage, and the capsule can be easily broken by applying an appropriate force when the contents are desired to be released. The breaking strength per capsule diameter can be 5 to 7 N / mm. In one embodiment, the breaking strength per capsule diameter is 5.5 to 8 N / mm. When within such a range, the capsule is difficult to break during storage, and the capsule can be easily broken by applying an appropriate force when the contents are desired to be released. The breaking strength per capsule diameter can be 6 to 8 N / mm. In addition to the above embodiments, for example, the breaking strength per capsule diameter can be 3.0 N / mm or more, or 3.5 N / mm or more, or 4.0 N / mm or more, or 4.5 N / mm or more, or 5.0 N / mm or more, or 5.3 N / mm or more, or 5.5 N / mm or more, or 6.0 N / mm or more, or 6.3 N / mm or more, or 6.5 N / mm or more, or 6.7 N / mm or more, or 7.0 N / mm or more. For example, the breaking strength per capsule diameter can be 8 N / mm or less, or 7.6 N / mm or less, or 7.5 N / mm or less, or 7.2 N / mm or less, or 7.0 N / mm or less. For example, the breaking strength per capsule diameter is 3.0 to 8 N / mm, or 3.0 to 7.6 N / mm, or 3.0 to 7.5 N / mm, or 3.0 to 7.2 N / mm, or 3.0 to 7.0 N / mm, or 3.5 to 8 N / mm, or 3.5 to 7.6 N / mm, or 3.5 to 7.5 N / mm, or 3.5 to 7.2 N / mm, or 3.5 to 7.0 N / mm, or 4.0 to 8 N / mm, or 4.0 to 7.6 N / mm, or 4.0 to 7.5 N / mm, or 4.0 to 7.2 N / mm, or 4.0 to 7.0 N / mm, or 4.5 to 8 N / mm, or 4.5 to 7.6 N / mm, or 4.5 to 7.5 N / mm, or 4.5 to 7.2 N / mm, or 4.5 to 7.0 N / mm, or 5.0 to 8 N / mm, or 5.0 to 7.6 N / mm, or 5.0 to 7.5 N / mm, or 5.0 to 7.2 N / mm, or 5.0 to 7.0 N / mm, or 5.3 to 8 N / mm, or 5.3 to 7.6 N / mm, or 5.3 to 7.5 N / mm, or 5.3 to 7.2 N / mm, or 5.3 to 7.0 N / mm, or 5.5 to 8 N / mm, or 5.5 to 7.6 N / mm, or 5.5 to 7.5 N / mm, or 5.5 to 7.2 N / mm, or 5.5 to 7.0 N / mm, or 6.0 to 8 N / mm, or 6.0 to 7.6 N / mm, or 6.0 to 7.5 N / mm, or 6.0 to 7.2 N / mm, or 6.0 to 7.0 N / mm, or 6.3 to 8 N / mm, or 6.3 to 7.6 N / mm, or 6.3 to 7.5 N / mm, or 6.3 to 7.2 N / mm, or 6.3 to 7.0 N / mm, or 6.5 to 8 N / mm, or 6.5 to 7.6 N / mm, or 6.5 to 7.5 N / mm, or 6.5 to 7.2 N / mm, or 6.5 to 7.0 N / mm, or 6.7 to 8 N / mm, or 6.7 to 7.6 N / mm, or 6.7 to 7.5 N / mm, or 6.7 to 7.2 N / mm, or 6.7 to 7.0 N / mm, or 7.0 to 8 N / mm, or 7.0 to 7.6 N / mm, or 7.0 to 7.5 N / mm, or 7.0 to 7.2 N / mm, can be in the range of. In this specification, the "destruction strength per capsule diameter" is calculated by dividing the destruction strength (N) of the capsule by the diameter (D) (mm) of the capsule. The destruction strength (N) is measured by continuously applying a load vertically to the capsule particles until they collapse. The maximum load at the moment the capsule breaks is the destruction strength (N) of the capsule. The destruction strength (N) is measured, for example, using a rheometer (e.g., Rheometer CR-3000EX, manufactured by Sun Scientific Co., Ltd.) and analyzed by a Rheo Data analyzer for Win (physical property data automatic analysis software, manufactured by Sun Scientific Co., Ltd.). The diameter (mm) of the capsule is measured as the average of the major axis (mm) and the minor axis.

[0018] The diameter (D) (mm) of the capsule is not particularly limited and can be set according to the size of the smoking device in which the capsule is used (e.g., the diameter size of the tobacco). The diameter (D) of the capsule is, for example, 1.5 to 10.0 mm, preferably 2.0 to 5 mm, and more preferably 2.5 to 4.5 mm. In order to make the quality of capsule collapsibility uniform, it is preferable that the average value of the diameter (D) of the capsule is within the above range. In one embodiment, the diameter (D) (mm) of the capsule is 2.0 to 3.0 mm (preferably 2.5 to 3.0 mm). In one embodiment, the diameter (D) (mm) of the capsule is 3.0 to 5.0 mm (preferably 3.0 to 4.5 mm).

[0019] By adjusting the composition and amount of the capsule film described below, the composition and amount of the capsule content liquid, the adjustment in the capsule manufacturing process (e.g., the cooling process, drying process, etc. in the in-droplet method described later), and / or coating, the diameter and destruction strength of the capsule can be adjusted within the scope of the present invention.

[0020] The film ratio of the capsule is not particularly limited, but is preferably 7.0 to 20.0% by weight from the viewpoints of excellent heat resistance and moisture resistance, being more easily broken when an appropriate force is applied by hand, and having a good feeling of cracking. For example, the film ratio of the capsule is 10 to 17.0% by weight, or 11.0 to 19.0% by weight, or 11.0 to 16.0% by weight, or 13.0 to 19.0% by weight. For example, the film ratio of the capsule can be in the range of 8.0 to 20.0% by weight, or 8.0 to 19.0% by weight, or 8.0 to 18.0% by weight, or 8.0 to 17.0% by weight, or 8.0 to 16.0% by weight, or 8.0 to 15.0% by weight, or 8.0 to 14.0% by weight, or 8.0 to 13.0% by weight, or 8.0 to 12.0% by weight, or 8.0 to 11.0% by weight.

[0041] When the content is left standing in an environment at a temperature of 25 °C and a relative humidity of 40%, the volatile amount (VC) of the content in 4 hours is 3.0% by weight or more based on the total weight of the formulated content. One of the features of the capsule of the present invention is that such a highly volatile content is encapsulated. By containing such a content, when the capsule disintegrates and the content is released, a stronger fragrance or irritation can be felt. The capsule of one embodiment of the present invention has excellent storage stability of the capsule content, with the volatilization of the content during storage being suppressed even when such a highly volatile content is encapsulated. In one embodiment, the volatile amount (VC) of the content in 4 hours is preferably 3.0 to 25% by weight, more preferably 3.5 to 20% by weight, and still more preferably 3.5 to 15% by weight. The volatile amount (VC) of the content in 4 hours is, for example, 3.5% by weight or more, or 3.6% by weight or more, or 4.0% by weight or more, or 4.5% by weight or more, or 5.0% by weight or more, or 5.1% by weight or more, or 5.5% by weight or more, or 5.6% by weight or more, or 6.0% by weight or more, or 6.3% by weight or more.

The volatilization amount (VC) of the content within 4 hours is, for example, 3.0 to 20% by weight, or 3.0 to 15% by weight, or 3.0 to 13% by weight, or 3.0 to 12% by weight, or 3.0 to 11% by weight, or 3.0 to 10% by weight, or 3.0 to 9% by weight, or 3.0 to 8% by weight, or 3.0 to 7% by weight, or 3.5 to 25% by weight, or 3.5 to 13% by weight, or 3.5 to 12% by weight, or 3.5 to 11% by weight, or 3.5 to 10% by weight, or 3.5 to 9% by weight, or 3.5 to 8% by weight, or 3.5 to 7% by weight, or 4.0 to 25% by weight, 4.0 to 20% by weight, or 4.0 to 15% by weight, or 4.0 to 13% by weight, or 4.0 to 12% by weight, or 4.0 to 11% by weight, or 4.0 to 10% by weight, or 4.0 to 9% by weight, or 4.0 to 8% by weight, or 4.0 to 7% by weight, or 4.5 to 25% by weight, 4.5 to 20% by weight, or 4.5 to 15% by weight, or 4.5 to 13% by weight, or 4.5 to 12% by weight, or 4.5 to 11% by weight, or 4.5 to 10% by weight, or 4.5 to 9% by weight, or 4.5 to 8% by weight, or 4.5 to 7% by weight, or 5.0 to 25% by weight, 5.0 to 20% by weight, or 5.0 to 15% by weight, or 5.0 to 13% by weight, or 5.0 to 12% by weight, or 5.0 to 11% by weight, or 5.0 to 10% by weight, or 5.0 to 9% by weight, or 5.0 to 8% by weight, or 5.0 to 7% by weight, or 5.1 to 25% by weight, 5.1 to 20% by weight, or 5.1 to 15% by weight, or 5.1 to 13% by weight, or 5.1 to 12% by weight, or 5.1 to 11% by weight, or 5.1 to 10% by weight, or 5.1 to 9% by weight, or 5.1 to 8% by weight, or 5.1 to 7% by weight, or 5.5 to 25% by weight, 5.5 to 20% by weight, or 5.5 to 15% by weight, or 5.5 to 13% by weight, or 5.5 to 12% by weight, or 5.5 to 11% by weight, or 5.5 to 10% by weight, or 5.5 to 9% by weight, or 5.5 to 8% by weight, or 5.5 to 7% by weight, or 5.6 to 25% by weight, 5.6 to 20% by weight, or 5.6 to 15% by weight, or 5.6 to 13% by weight, or 5.6 to 12% by weight, or 5.6 to 11% by weight, or 5.6 to 10% by weight, or 5.6 to 9% by weight, or 5.6 to 8% by weight, or 5.6 to 7% by weight, or 6.0 to 25% by weight, 6.0 to 20% by weight, or 6.0 to 15% by weight, or 6.0 to 13% by weight, or 6.0 to 12% by weight, or 6.0 to 11% by weight, or 6.0 to 10% by weight, or 6.0 to 9% by weight, or 6.0 to 8% by weight, or 6.0 to 7% by weight, or 6.3 to 25% by weight, 6.3 to 20% by weight, or 6.3 to 15% by weight, or 6.3 to 13% by weight, or 6.3 to 12% by weight, or 6.3 to 11% by weight, or 6.3 to 10% by weight, or 6.3 to 9% by weight, or 6.3 to 8% by weight, or 6.3 to 7% by weight, can be in the range of.

[0042] (Capsule film) The capsule film contains a polysaccharide and, if necessary, a hydrophilic colloid other than the polysaccharide such as gelatin, a plasticizer, a colorant, a sweetener, and a flavor. By including a polysaccharide in the capsule film, it is possible to produce a capsule that suppresses the volatilization of the encapsulated content.

[0043] The polysaccharides are not particularly limited. For example, seaweed-derived polysaccharides such as carrageenan, agar, alginic acid or its salts, furcellaran, and curdlan; resin-derived polysaccharides such as ghatti gum and gum arabic; microbial-derived polysaccharides such as pullulan, welan gum, xanthan gum, and gellan gum; plant-derived polysaccharides such as tragacanth gum, pectin, glucomannan, starch, and dextrins; seed-derived polysaccharides such as guar gum, guar gum derivatives, enzymatically degraded guar gum, tara gum, tamarind seed gum, locust bean gum, psyllium seed gum, and flaxseed gum; fermented polysaccharides such as diutan gum, etc. These can be commercially available products. These can be used alone or in combination of two or more. Among them, from the viewpoint of preventing volatilization of the content, gellan gum, carrageenan, agar, guar gum, guar gum derivatives, enzymatically degraded guar gum, alginic acid or its salts, starch, and dextrins are preferable, and gellan gum, carrageenan, starch, and dextrins are more preferable.

[0044] From the viewpoint of obtaining capsules having a desired breaking strength and film strength, it is preferable that the polysaccharide contains a polysaccharide having a gelling ability. "Having a gelling ability" means the property of gelling (preferably at 50 °C or lower, more preferably at 40 °C or lower). Examples of the polysaccharide having a gelling ability include at least one selected from the group consisting of gellan gum, carrageenan, and agar.

[0045] Furthermore, from the viewpoint of preventing volatilization of the content, the polysaccharide is preferably any of the following. (i) Gellan gum, (ii) A combination of gellan gum and carrageenan (iii) A combination of gellan gum, carrageenan, and dextrins (iv) A combination of gellan gum, carrageenan, and starch (v) A combination of gellan gum, carrageenan, and agar (vi) A combination of gellan gum, carrageenan, agar, and dextrins (vii) A combination of gellan gum, carrageenan, agar, and starch (viii) A combination of carrageenan with guar gum, a guar gum derivative, and / or a guar gum degradation product (ix) A combination of carrageenan, guar gum, a guar gum derivative, and / or a guar gum degradation product, and dextrins (x) A combination of carrageenan, guar gum, a guar gum derivative, and / or a guar gum degradation product, and starch (xi) A combination of gellan gum, carrageenan, agar, and guar gum, a guar gum derivative, and / or a guar gum degradation product (xii) A combination of gellan gum, carrageenan, agar, guar gum, a guar gum derivative, and / or a guar gum degradation product, and dextrins (xiii) A combination of gellan gum, carrageenan, agar, guar gum, a guar gum derivative, and / or a guar gum degradation product, and starch

[0046] In one embodiment, the capsule film contains a combination of a polysaccharide and gelatin. However, when agar is included as the polysaccharide, it is preferably gelatin - free. Preferred combination examples include the combination of any one of the polysaccharide combinations (i) - (iv), (viii) - (x) exemplified above and gelatin.

[0047] In one embodiment, the capsule film does not contain gelatin. In such a case, it is good in terms of heat resistance. Gelatin generally has a lower melting point compared to polysaccharides, so when exposed to a high - humidity state such as during smoking, it may deform or release the content liquid when heated at 40 - 60°C. Also, from a religious perspective, capsules that do not use gelatin derived from cows or pigs are desired.

[0048] The content of the polysaccharide is not particularly limited as long as it does not interfere with the effects of the present invention. However, from the viewpoints of preventing volatilization of the content and the feeling of capsule cracking, 15 to 96% by weight, more preferably 20 to 95% by weight, still more preferably 25 to 90% by weight, and particularly preferably 30 to 90% by weight, based on the total weight of the capsule film, is preferred. When gelatin is included, the total content of the polysaccharide and gelatin is preferably 70 to 99% by weight, and more preferably 80 to 98% by weight, based on the total weight of the capsule film. When gelatin is not included, the content of the polysaccharide is preferably 70 to 99% by weight, and more preferably 80 to 95% by weight, based on the total weight of the capsule film. In one embodiment, the content of the polysaccharide having gelling ability is not particularly limited as long as it does not interfere with the effects of the present invention. However, from the viewpoints of the breaking strength and film strength of the capsule, for example, 50 to 95% by weight, more preferably 55 to 95% by weight, based on the total weight of the capsule film, is preferred. In one embodiment, the content of the polysaccharide having gelling ability is not particularly limited as long as it does not interfere with the effects of the present invention. However, from the viewpoints of the breaking strength and film strength of the capsule, for example, 20 to 95% by weight, more preferably 20 to 90% by weight, based on the total weight of the capsule film, is preferred. For example, the content of the polysaccharide having gelling ability can be 20 to 80% by weight, or 25 to 95% by weight, or 25 to 90% by weight.

[0049] Gellan gum can be classified into acylated gellan gum (native gellan gum) and deacylated gellan gum depending on the presence or absence of acylation. Acylated gellan gum generally has the property of forming a soft and extensible gel. Deacylated gellan gum generally has the property of forming a hard and brittle gel. In the present invention, either can be used, but deacylated gellan gum is preferred in terms of its low gelling temperature and suitability for capsule production. Commercially available products of acylated gellan gum include, for example, Kelcogel HT and Kelcogel LT100 manufactured by CP Kelco. Commercially available products of deacylated gellan gum include, for example, Kelcogel and Kelcogel F manufactured by CP Kelco. The content of gellan gum is not particularly limited, but is usually 1 to 99% by weight, preferably 3 to 95% by weight, more preferably 5 to 95% by weight, still more preferably 10 to 90% by weight, even more preferably 20 to 70% by weight, and particularly preferably 25 to 60% by weight, based on the total weight of the capsule film. In certain embodiments, the content of gellan gum is, for example, based on the total weight of the capsule film 1 to 95% by weight, or 3 to 95% by weight, or 5 to 95% by weight, or 10 to 95% by weight, or 15 to 95% by weight, or 20 to 95% by weight, or 25 to 95% by weight, or 30 to 95% by weight, or 35 to 95% by weight, or 40 to 95% by weight, or 45 to 95% by weight, or 50 to 95% by weight, or 55 to 95% by weight, or 60 to 95% by weight, or 1 to 90% by weight, or 3 to 90% by weight, or 5 to 90% by weight, or 10 to 90% by weight, or 15 to 90% by weight, or 20 to 90% by weight, or 25 to 90% by weight, or 30 to 90% by weight, or 35 to 90% by weight, or 40 to 90% by weight, or 45 to 90% by weight, or 50 to 90% by weight, or 55 to 90% by weight, or 60 to 90% by weight, or 1 to 85% by weight, or 3 to 85% by weight, or 5 to 85% by weight, or 10 to 85% by weight, or 15 to 85% by weight, or 20 to 85% by weight, or 25 to 85% by weight, or 30 to 85% by weight, or 35 to 85% by weight, or 40 to 85% by weight, or 45 to 85% by weight, or 50 to 85% by weight, or 55 to 85% by weight, or 60 to 85% by weight, or 1 to 80% by weight, or 3 to 80% by weight, or 5 to 80% by weight, or 10 to 80% by weight, or 15 to 80% by weight, or 20 to 80% by weight, or 25 to 80% by weight, or 30 to 80% by weight, or 35 to 80% by weight, or 40 to 80% by weight, or 45 to 80% by weight, or 50 to 80% by weight, or 55 to 80% by weight, or 60 to 80% by weight, or 1 to 75% by weight, or 3 to 75% by weight, or 5 to 75% by weight, or 10 to 75% by weight, or 15 to 75% by weight, or 20 to 75% by weight, or 25 to 75% by weight, or 30 to 75% by weight, or 35 to 75% by weight, or 40 to 75% by weight, or 45 to 75% by weight, or 50 to 75% by weight, or 55 to 75% by weight, or 60 to 75% by weight, or 1 to 70% by weight, or 3 to 70% by weight, or 5 to 70% by weight, or 10 to 70% by weight, or 15 to 70% by weight, or 20 to 70% by weight, or 25 to 70% by weight, or 30 to 70% by weight, or 35 to 70% by weight, or 40 to 70% by weight, or 45 to 70% by weight, or 50 to 70% by weight, or 55 to 70% by weight, or 60 to 70% by weight, or 1 to 65% by weight, or 3 to 65% by weight, or 5 to 65% by weight, or 10 to 65% by weight, or 15 to 65% by weight, or 20 to 65% by weight, or 25 to 65% by weight, or 30 to 65% by weight, or 35 to 65% by weight, or 40 to 65% by weight, or 45 to 65% by weight, or 50 to 65% by weight, or 55 to 65% by weight, or 60 to 65% by weight, or 1 to 60% by weight, or 3 to 60% by weight, or 5 to 60% by weight, or 10 to 60% by weight, or 15 to 60% by weight, or 20 to 60% by weight, or 25 to 60% by weight, or 30 to 60% by weight, or 35 to 60% by weight, or 40 to 60% by weight, or 45 to 60% by weight, or 50 to 60% by weight, or 55 to 60% by weight, or 1 to 55% by weight, or 3 to 55% by weight, or 5 to 55% by weight, or 10 to 55% by weight, or 15 to 55% by weight, or 20 to 55% by weight, or 25 to 55% by weight, or 30 to 55% by weight, or 35 to 55% by weight, or 40 to 55% by weight, or 45 to 55% by weight, or 50 to 55% by weight, or 1 to 50% by weight, or 3 to 50% by weight, or 5 to 50% by weight, or 10 to 50% by weight, or 15 to 50% by weight, or 20 to 50% by weight, or 25 to 50% by weight, or 30 to 50% by weight, or 35 to 50% by weight, or 40 to 50% by weight, or 45 to 50% by weight, or 1 to 45% by weight, or 3 to 45% by weight, or 5 to 45% by weight, or 10 to 45% by weight, or 15 to 45% by weight, or 20 to 45% by weight, or 25 to 45% by weight, or 30 to 45% by weight, or 35 to 45% by weight, or 40 to 45% by weight, or 1 to 40% by weight, or 3 to 40% by weight, or 5 to 40% by weight, or 10 to 40% by weight, or 15 to 40% by weight, or 20 to 40% by weight, or 25 to 40% by weight, or 30 to 40% by weight, or 35 to 40% by weight, or 1 to 35% by weight, or 3 to 35% by weight, or 5 to 35% by weight, or 10 to 35% by weight, or 15 to 35% by weight, or 20 to 35% by weight, or 25 to 35% by weight, or 30 to 35% by weight, may be in the range of.

Among them, κ (kappa) - carrageenan and ι (iota) - carrageenan are preferred in terms of excellent gelling ability during production, excellent heat resistance and moisture resistance of the obtained capsules, and the ability to be easily broken when external pressure is applied, resulting in a good sense of breakage and touch. Carrageenan is produced by extracting from the whole algae of the families Sargassaceae, Grateloupiaceae, and Gigartinaceae of red algae using known means and methods. Commercially available products of carrageenan can be used. Examples of commercially available products include GenubiSco (iota type, Sankyo Co., Ltd.), GenubiGel (kappa type, Sankyo Co., Ltd.), SatiaGel ME4SB (SatiaGel ME4SB, kappa type, Cargill Japan Co., Ltd.), etc., and SatiaGel ME4 (SatiaGel ME4, kappa type, Cargill Japan Co., Ltd.) is preferably mentioned. Also, when the capsule is made transparent or semi - transparent and colored according to the image of the product, it is preferable to use kappa - carrageenan.

[0051] Although the viscosity of the carrageenan is not particularly limited, in terms of excellent storage stability, disintegration properties, etc. of the resulting capsules, being more easily broken when an appropriate force is applied by hand, having a good feeling of breaking, and being able to enjoy the touch, those with a viscosity of 5 mPa·s or more are preferred. The upper limit of the viscosity is not particularly limited, but those with 500 mPa·s or less are preferred. The viscosity is a value measured by the method described in the 8th edition of the Food Additive Codex, and can be measured, for example, using a B-type viscometer (manufacturer name: BROOK FIELD, MODEL: LVDVE115). Although carrageenan is not particularly limited, in terms of excellent storage stability, disintegration properties, etc. of the resulting capsules, for example, those with a pH of 6.5 to 13.0 at 20°C in a 1% solution are more preferred, and those with a pH of 7.8 to 12.0 are even more preferred.

[0052] The content of carrageenan is not particularly limited, but is usually 1.0 to 50.0% by weight, preferably 3.0 to 45.0% by weight, based on the total weight of the capsule film. Alternatively, the content of carrageenan can be, for example, 5.0 to 40.0% by weight, or 5.0 to 35.0% by weight, or 5.0 to 30.0% by weight, or 5.0 to 25.0% by weight, or 5.0 to 20.0% by weight, or 5.0 to 15.0% by weight. As the amount of carrageenan increases, the viscosity of the capsule film solution tends to increase. In a specific embodiment, the content of carrageenan is, for example, based on the total weight of the capsule film 1 to 50% by weight, or 3 to 50% by weight, or 5 to 50% by weight, or 7 to 50% by weight, or 10 to 50% by weight, or 15 to 50% by weight, or 1 to 40% by weight, or 3 to 40% by weight, or 5 to 40% by weight, or 7 to 40% by weight, or 10 to 40% by weight, or 15 to 40% by weight, or 1 to 30% by weight, or 3 to 30% by weight, or 5 to 30% by weight, or 7 to 30% by weight, or 10 to 30% by weight, or 15 to 30% by weight, or 1 to 25% by weight, or 3 to 25% by weight, or 5 to 25% by weight, or 7 to 25% by weight, or 10 to 25% by weight, or 15 to 25% by weight, or 1 to 20% by weight, or 3 to 20% by weight, or 5 to 20% by weight, or 7 to 20% by weight, or 10 to 20% by weight, or 15 to 20% by weight, or 1 to 15% by weight, or 3 to 15% by weight, or 5 to 15% by weight, or 7 to 15% by weight, or 10 to 15% by weight, may be in the range of.

The raw material of the agar used in the present invention is not particularly limited, and for example, red algae etc. may be mentioned. Examples of red algae include tengusa, ogonori, etc., and tengusa is preferred. Commercially available products can be used as the agar. Among them, agar having high strength is preferred in terms of excellent heat resistance and moisture resistance of the obtained capsules, and being easily broken when external pressure is applied, and obtaining a good sense of cracking and touch. Specifically, the agar preferably has a jelly strength of 600 g / cm 2 or more, more preferably 650 g / cm 2 or more, and even more preferably 700 g / cm 2 or more. The jelly strength is a value measured by the Nikkenso method. Specifically, for a gel prepared by preparing a 1.5% solution of agar, leaving it at 20°C for 15 hours and allowing it to solidify, the maximum weight (g) that can be endured for 20 seconds per 1 cm 2 of the surface is taken as the jelly strength. The jelly strength means the value at a concentration of 1.5%. These may be used alone or in combination of two or more. The content of agar is not particularly limited, but in terms of viscosity, it is usually 1 to 60% by weight, for example, 1 to 55% by weight, or 20 to 55% by weight, based on the total weight of the capsule film. For example, the content of agar can be 60% by weight or less, or 55% by weight or less, or 50% by weight or less, or 45% by weight or less, or 40% by weight or less, or 30% by weight or less, or 25% by weight or less, or 20% by weight or less.

[0054] Guar gum is produced by pulverizing or extracting from the seeds of Cyamopsis tetragonoloba of the legume family using known means and methods. Further, instead of or in addition to guar gum, a guar gum derivative may be used. The guar gum derivative is not particularly limited, and examples thereof include hydroxypropyl guar gum and cationized guar gum. The content of guar gum and the guar gum derivative is not particularly limited, but in terms of viscosity, it is 1 to 20% by weight, preferably 1.5 to 10% by weight, based on the total weight of the capsule film.

[0056] The capsule film may contain alginic acid or its salt from the viewpoints of the storage stability and disintegration property of the capsule. The alginate is not particularly limited, and for example, metal salts of alginic acid are preferably mentioned. Specifically, alkali metal salts such as sodium salt and potassium salt, alkaline earth metal salts such as calcium and magnesium salts, and metal salts such as iron and tin are mentioned. Sodium alginate and potassium alginate are particularly preferred, and sodium alginate is most preferred. These may be used alone or in combination of two or more. As the metal salt of alginic acid, those having a low viscosity are preferred. For example, those having a viscosity of 500 mPa·s or less are preferred, and those having a viscosity of 400 mPa·s or less are more preferred. The viscosity is a value measured by the method described in the 8th Edition of the Food Additive Official Monograph, and can be measured using, for example, a B-type viscometer (manufacturer name: BROOK FIELD, MODEL: LVDVE115). Alginic acid or its salt may be used alone or in combination of two or more. When the capsule is made transparent or translucent, it is preferable to use sodium alginate as the alginate. This facilitates the coloring of the capsule. Alginic acid or its salt can be obtained by extracting alginic acid from brown algae by known means and methods. Commercially available products can be used. Examples of commercially available products include Sun Algin (Sansei Co., Ltd.).

[0057] The content of alginic acid or its salt is not particularly limited, but in terms of viscosity, it is, for example, 1.0 to 50.0% by weight, preferably 3.0 to 45.0% by weight, based on the total weight of the capsule film.

[0058] For dextrins, those having a dextrose equivalent (DE) of 20 or less are preferred. The dextrose equivalent (DE) is a relative measure indicating the degree of hydrolysis when the reducing power of dextrose (glucose) is set to 100. The closer it is to 0, the closer the properties are to starch, and the closer it is to 100, the more the hydrolysis of starch progresses and the properties become similar to glucose. The dextrose equivalent (DE) can be measured by the Lane-Eynon method. The dextrins are not particularly limited, and examples include dextrin, maltodextrin, resistant dextrin, cyclodextrin (α, β, or γ), etc. Commercially available products can be used. The content of dextrin is preferably 1 to 40% by weight, more preferably 5 to 30% by weight, based on the total weight of the capsule film. For example, as dextrin, maltodextrin, and resistant dextrin, products manufactured by Matsutani Chemical Industry Co., Ltd. can be used.

[0059] The starch is not particularly limited, and commercially available products can be used. The content of starch is preferably 1 to 40% by weight, more preferably 5 to 30% by weight, based on the total weight of the capsule film.

[0060] The gelatin is not particularly limited, and examples include porcine gelatin, bovine gelatin, fish gelatin, etc. Also, as gelatin, gelatin derivatives such as succinylated gelatin, gelatin hydrolyzate, hydrolyzed gelatin, crosslinked gelatin, etc. may be used without particular limitation. Commercially available products can be used. These may be used alone or in combination of two or more. For the purpose of not using components derived from mammals (e.g., cows, pigs, etc.) due to religious restrictions, allergy problems, etc., non-mammalian capsules can be obtained by not using mammalian-derived gelatin.

[0061] The gelatin is not particularly limited, but high-strength gelatin is preferred because the resulting capsules are excellent in heat resistance and moisture resistance, can be more easily broken when an appropriate force is applied by hand, have a good cracking feeling, and can enjoy the touch. For example, those with a Bloom strength (Bloom number) of 190 or more are preferred, those with 220 or more are more preferred, and those with 250 or more are even more preferred. The Bloom strength is defined by the mass required for a cylindrical piston with a diameter of 12.7 mm to be pushed into a 4 mm gel. Commercially available products (e.g., products manufactured by Rousselot) can be used.

[0062] The gelatin content is not particularly limited, but is usually less than 75% by weight, preferably 70% by weight or less, more preferably 60% by weight or less, still more preferably 58% by weight or less, yet more preferably 55% by weight or less, and even more preferably 50% by weight or less, based on the total weight of the capsule film. The higher the gelatin content, the harder the capsule becomes and the higher the breaking strength, but there is a tendency for it to be less likely to be crushed.

[0063] The capsule film preferably contains a plasticizer in terms of breaking strength and impact resistance. The plasticizer is not particularly limited, and examples thereof include polyhydric alcohols such as glycerin, polyethylene glycol, propylene glycol, and polypropylene glycol; monosaccharides such as glucose, fructose, glucose, and galactose; disaccharides such as sucrose, maltose, trehalose, and coupling sugar, and oligosaccharides such as maltooligosaccharide; sugar alcohols such as sorbitol, maltitol, lactitol, palatinite, xylitol, mannitol, and galactitol; polyvinyl alcohol; triacetin; starch derivatives such as polydextrose and reduced starch hydrolyzate; and cellulose derivatives such as hydroxypropyl methylcellulose (HPMC), hydroxypropyl cellulose (HPC), methylcellulose (MC), and carboxymethylcellulose (CMC). These may be used alone or in combination of two or more. Commercially available products can be used. For example, as maltooligosaccharide, products manufactured by Matsutani Chemical Industry Co., Ltd. can be used. As the starch derivative, those having a DE (degree of starch hydrolysis) of about 10 to 90 are preferred.

[0064] The content of the plasticizer is not particularly limited, but considering that the resulting capsule is excellent in heat resistance and moisture resistance and can be easily broken when an appropriate force is applied by hand and the feel can also be enjoyed, for example, it can be less than 15% by weight, or 13% by weight or less. Also, the content of the plasticizer in the capsule film can be, for example, up to about 35% by weight and can be 30% by weight or less.

[0065] The content of the plasticizer is not particularly limited, but from the viewpoint of impact resistance, 1% to 30% by weight, preferably 4% to 20% by weight, is more preferable with respect to the total weight of the capsule film. Alternatively, the content of the plasticizer is preferably 1% to 50% by weight, preferably 1% to 45% by weight, more preferably 1% to 40% by weight, still more preferably 1% to 35% by weight, still more preferably 4% to 30% by weight, and even more preferably 4% to 25% by weight with respect to the total weight of the capsule film.

[0066] Among them, from the viewpoint of impact resistance, the plasticizer preferably contains glycerin. The content of glycerin is preferably 1% to 30% by weight, more preferably 4% to 20% by weight with respect to the total weight of the capsule film. When the capsule film contains gelatin, from the viewpoint of impact resistance, the content of glycerin is preferably 4% to 20% by weight with respect to the total weight of the capsule film.

The thickness (TH) of the capsule film can be measured, for example, using a digital microscope (for example, the product name manufactured by Keyence Corporation; VHX-900, using a calibration scale of 10 μm). In order to make the quality of capsule disintegration uniform, it is preferable that the average value of the thickness (TH) of the capsule film is within the above range.

[0075] From the viewpoint of preventing volatilization of the content, it is preferable that the ratio of the thickness (TH) of the capsule film to the volatilization amount (VC) of the content (TH (μm) / VC (wt%)) is 8 or more.

As TH / VC increases, prevention of volatilization of the content is achieved. On the other hand, if TH / VC becomes too large, a thick capsule is formed and it becomes difficult for the capsule to disintegrate, or it tends to be difficult to contain a highly volatile content. TH (μm) / VC (wt%) can be, for example, 9 or more, or 10 or more, or 11 or more, or 12 or more, or 13 or more, or 14 or more, or 15 or more, or 16 or more, or 17 or more, or 18 or more, or 19 or more, or 20 or more, or 21 or more, or 22 or more, or 23 or more. TH (μm) / VC (wt%) can be, for example, 50 or less, or 40 or less, or 35 or less, or 33 or less, or 30 or less, or 29 or less, or 28 or less, or 27 or less, or 26 or less, or 25 or less, or 24 or less, or 23 or less, or 22 or less, or 21 or less, or 20 or less, or 19 or less, or 18 or less, or 17.5 or less, or 17 or less, or 16.5 or less, or 16 or less, or 15.5 or less, or 15 or less. TH (μm) / VC (wt%) is, for example, 8 to 50, or 8 to 40, or 8 to 35, or 8 to 33, or 8 to 30, or 8 to 29, or 8 to 28, or 8 to 27, or 8 to 26, or 8 to 25, or 8 to 24, or 8 to 23, or 8 to 22, or 8 to 21, or 8 to 20, or 8 to 19, or 8 to 18, or 8 to 17.5, or 8 to 17, or 8 to 16.5, or 8 to 16, or 8 to 15.5, or 8 to 15, or 9 to 50, or 9 to 40, or 9 to 35, or 9 to 33, or 9 to 30, or 9 to 29, or 9 to 28, or 9 to 27, or 9 to 26, or 9 to 25, or 9 to 24, or 9 to 23, or 9 to 22, or 9 to 21, or 9 to 20, or 9 to 19, or 9 to 18, or 9 to 17.5, or 9 to 17, or 9 to 16.5, or 9 to 16, or 9 to 15.5, or 9 to 15, or 10 to 50, or 10 to 40, or 10 to 35, or 10 to 33, or 10 to 30, or 10 to 29, or 10 to 28, or 10 to 27, or 10 to 26, or 10 to 25, or 10 to 24, or 10 to 23, or 10 to 22, or 10 to 21, or 10 to 20, or 10 to 19, or 10 to 18, or 10 to 17.5, or 10 to 17, or 10 to 16.5, or 10 to 16, or 10 to 15.5, or 10 to 15, or 11 to 50, or 11 to 40, or 11 to 35, or 11 to 33, or 11 to 30, or 11 to 29, or 11 to 28, or 11 to 27, or 11 to 26, or 11 to 25, or 11 to 24, or 11 to 23, or 11 to 22, or 11 to 21, or 11 to 20, or 11 to 19, or 11 to 18, or 11 to 17.5, or 11 to 17, or 11 to 16.5, or 11 to 16, or 11 to 15.5, or 11 to 15, or 12 to 50, or 12 to 40, or 12 to 35, or 12 to 33, or 12 to 30, or 12 to 29, or 12 to 28, or 12 to 27, or 12 to 26, or 12 to 25, or 12 to 24, or 12 to 23, or 12 to 22, or 12 to 21, or 12 to 20, or 12 to 19, or 12 to 18, or 12 to 17.5, or 12 to 17, or 12 to 16.5, or 12 to 16, or 12 to 15.5, or 12 to 15, or 13 to 50, or 13 to 40, or 13 to 35, or 13 to 33, or 13 to 30, or 13 to 29, or 13 to 28, or 13 to 27, or 13 to 26, or 13 to 25, or 13 to 24, or 13 to 23, or 13 to 22, or 13 to 21, or 13 to 20, or 13 to 19, or 13 to 18, or 13 to 17.5, or 13 to 17, or 13 to 16.5, or 13 to 16, or 13 to 15.5, or 13 to 15, or 14 to 50, or 14 to 40, or 14 to 35, or 14 to 33, or 14 to 30, or 14 to 29, or 14 to 28, or 14 to 27, or 14 to 26, or 14 to 25, or 14 to 24, or 14 to 23, or 14 to 22, or 14 to 21, or 14 to 20, or 14 to 19, or 14 to 18, or 14 to 17.5, or 14 to 17, or 14 to 16.5, or 14 to 16, or 14 to 15.5, or 14 to 15, or 15 to 50, or 15 to 40, or 15 to 35, or 15 to 33, or 15 to 30, or 15 to 29, or 15 to 28, or 15 to 27, or 15 to 26, or 15 to 25, or 15 to 24, or 15 to 23, or 15 to 22, or 15 to 21, or 15 to 20, or 15 to 19, or 15 to 18, or 15 to 17.5, or 15 to 17, or 15 to 16.5, or 15 to 16, or 15 to 15.5, or 16 to 50, or 16 to 40, or 16 to 35, or 16 to 33, or 16 to 30, or 16 to 29, or 16 to 28, or 16 to 27, or 16 to 26, or 16 to 25, or 16 to 24, or 16 to 23, or 16 to 22, or 16 to 21, or 16 to 20, or 16 to 19, or 16 to 18, or 16 to 17.5, or 16 to 17, or 16 to 16.5, or 17 to 50, or 17 to 40, or 17 to 35, or 17 to 33, or 17 to 30, or 17 to 25, or 17 to 20, or 17 to 19, or 17 to 18, or 17 to 17.5, or 18 to 50, or 18 to 40, or 18 to 35, or 18 to 33, or 18 to 30, or 18 to 29, or 18 to 28, or 18 to 27, or 18 to 26, or 18 to 25, or 18 to 24, or 18 to 23, or 18 to 22, or 18 to 21, or 18 to 20, or 18 to 19, or 19 to 50, or 19 to 40, or 19 to 35, or 19 to 33, or 19 to 30, 19 to 29, 19 to 28, 19 to 27, 19 to 26, 19 to 25, 19 to 24, 19 to 23, 19 to 22, 19 to 21, or 19 to 20, or 20 to 50, or 20 to 40, or 20 to 35, or 20 to 33, or 20 to 30, or 20 to 29, or 20 to 28, or 20 to 27, or 20 to 26, or 20 to 25, or 20 to 24, or 20 to 23, or 20 to 22, or 20 to 21, or 21 to 50, or 21 to 40, or 21 to 35, or 21 to 33, or 21 to 30, or 21 to 29, or 21 to 28, or 21 to 27, or 21 to 26, or 21 to 25, or 21 to 24, or 21 to 23, or 21 to 22, or 22 to 50, or 22 to 40, or 22 to 35, or 22 to 33, or 22 to 30, or 22 to 29, or 22 to 28, or 22 to 27, or 22 to 26, or 22 to 25, or 22 to 24, or 22 to 23, or 23 to 50, or 23 to 40, or 23 to 35, or 23 to 33, or 23 to 30, or 23 to 29, or 23 to 28, or 23 to 27, or 23 to 26, or 23 to 25, or 23 to 24 can be in the range of.

[0076] The water activity value of the capsule film is preferably 0.400 to 0.650, more preferably 0.410 to 0.630, and even more preferably 0.420 to 0.620. Although water can also cause a loss of storage stability, only the water called "free water" can be utilized by the microorganisms involved in the spoilage of the capsules. The water activity value (Aw) means the ratio of free water measured by a Rotronic water activity measurement system at 22°C and 60% RH (relative humidity) immediately after production. Examples of the Rotronic water activity measurement system include the Aw series (for example, Aw-Lab, Aw-Palm, Aw-Quick, etc.).

[0077] The water content of the capsule film is not particularly limited, but is preferably 10.0% or more and 19.0% or less, more preferably 11.0% or more and 18.0% or less, and still more preferably 12.0 to 16.0%. Since any capsule can be easily broken with the same force and the disintegration quality becomes uniform, it is particularly preferable that the average value of the water content of the capsules is within the above range. In this specification, the water content is the value measured by the method described in the Japanese Pharmacopoeia. Specifically, it is the value measured and calculated by measuring the dry weight after treatment at 110 °C for 120 minutes from the state of 22 °C and 60% RH.

[0078] <Method for manufacturing capsules> The method for manufacturing capsules is not particularly limited and can be appropriately selected from known manufacturing methods. For example, the methods described in Japanese Patent No. 5047285, Japanese Patent Publication No. 10-506841, Japanese Patent No. 5581446, etc. can be used. For example, a liquid dropping method (seamless capsule method) using a double or multiple (triple or more) nozzle can be mentioned. By this method, the capsule can be manufactured by filling the capsule content into the capsule film, molding, and drying. Specifically, a capsule film solution containing the constituent components of the capsule film, the capsule content, and, if necessary, an intermediate layer material are extruded into a carrier fluid using a double or multiple (triple or more) nozzle, and the capsule content is filled into the capsule film. Then, the capsule is molded by irradiating with light, heating, and / or cooling to cure the capsule film solution, and subsequently dried. The capsule film solution can be prepared by dissolving the components of the capsule film in a solvent. The solvent is not particularly limited as long as it does not interfere with the effects of the present invention. Examples include alcohols such as water and ethanol, and water is preferred. When dissolving the film-forming agent in the solvent, heat treatment is preferred. The heating temperature is not particularly limited, but is about 60 to 100 °C, and more preferably about 70 to 95 °C. The viscosity of the capsule film solution (mixture) at 95 °C is not particularly limited, but from the viewpoint of obtaining effects such as the disintegration property of the capsule (uniformity of the film), 50 to 500 mPa·s is preferred, and 50 to 200 mPa·s is more preferred. The viscosity can be measured using, for example, a B-type viscometer (manufacturer name: BROOK FIELD, MODEL: LVDVE115).

[0079] After forming wet capsules by the above method, they are dried to obtain dry capsules. Generally, this drying is performed using, for example, a "rotary drum dryer" equipped with a ventilation device. For other small capsules such as seamless capsules, a fluidized drying method in which they are blown up and dried while being fluidized may also be used. The drying temperature is not particularly limited, but may be about 20 to 50 °C.

[0080] <Coating> In order to maintain the humidity of the capsules and make them prone to cracking, they may be coated with various coating agents such as zein and have a coating layer. The coating agent is not particularly limited, but includes generally used known coating agents, for example, hydroxypropyl methylcellulose, ethylcellulose, methacrylic acid copolymer, shellac, water-soluble shellac, silicone oil, methylcellulose, carnauba wax, zein, etc. These may be used alone or, if necessary, in an appropriate combination of two or more. Examples of commercially available products include Opadry, Eudragit, etc. The thickness of the coating layer may be within a range that does not interfere with the effects of the present invention and is not particularly limited.

[0081] As coating methods, there can be mentioned a method of spraying or applying a coating agent dissolved or dispersed in a volatile solvent or the like to the dried capsules and then volatilizing the volatile solvent (top-coating method), a method of immersing the dried capsules in a coating agent dissolved or dispersed in a volatile solvent or the like and then volatilizing the volatile solvent (dip method), a method of previously dispersing and suspending during the preparation of the capsule film solution (kneading method), etc., and there is no particular limitation on the method.

[0082] <Use of Capsules> The disintegratable capsule according to one embodiment of the present invention can be used in a smoking device, and preferably can be used in cigarettes, cigars or pipes. In one embodiment, the capsule is inserted into the filter. According to one embodiment of the present invention, there is provided a filter for a smoking device including the capsule of the above embodiment. Further, according to one embodiment of the present invention, there is provided a smoking device including the capsule of the above embodiment or a filter including the capsule.

[0083] The present invention includes aspects in which the above configurations are variously combined within the technical scope of the present invention as long as the effects of the present invention are achieved.

Examples

[0084] Hereinafter, the present invention will be described in detail with reference to examples, but the technical scope of the present invention is not limited thereto. Unless otherwise specified, parts and % in each example are all based on weight.

[0085] Also, the measurement of each physical property was performed by the following method. (Thickness of Capsule Film) The thickness of the capsule film was measured at four locations where the center of the capsule was divided into two and the left, right, upper and lower parts were substantially equal, and the average value was taken. For the measurement, a VHX-900F manufactured by Keyence was used. (Capsule Diameter) The capsule diameter was measured using a Mitutoyo micro gauge. The diameter (mm) of the capsule was determined by measuring the major axis (mm) and the minor axis, and taking the average value. The measurement was performed on 20 samples, and the average value was taken as the diameter. (Breaking strength of the capsule) Using a rheometer CR-3000EX (manufactured by San-ei Kagaku Co., Ltd.), the breaking strength of 20 capsules was measured, and the average value was taken as the breaking strength of the capsule.

[0086] (Volatile content VC) Each capsule content was placed in a glass petri dish with a diameter of 87 mm (height 19 mm) and left standing for 4 hours in a thermo-hygrostat THN062PC type (manufacturer: ADVANTEC Toyo Co., Ltd.) set at a temperature of 25°C (±2°C) and a relative humidity of 40% (±5%). The initial weight (formulation weight) (W1) of the capsule content and the weight (W2) of the capsule content after 4 hours were measured. The capsule content used was approximately 2 g each, and an analytical electronic balance GR-200 was used to measure the capsule weight. For each capsule content, the volatile content VC was calculated from the following formula. [Volatile content VC (wt%)] = (W1 - W2) / W1 × 100

[0087] (Measurement of the volatile content of the content encapsulated in the capsule) 1. Preparation of capsule content The fragrance components and lipophilic solvents shown in Table 1 were added and mixed to obtain capsule contents 1 to 10. For each capsule content, the volatile content VC was calculated. The results are shown in Table 1. Details of the fragrance components and lipophilic solvents used are as follows. (Fragrance components) Fragrance 1: L-menthol (manufactured by Takasago Perfumery Co., Ltd.) Fragrance 2: Grape & Berry Fragrance No984 (manufactured by Osaka Perfumery Co., Ltd.) Fragrance 3: Spearmint oil (manufactured by Nagaoka Sangyo Co., Ltd.) Fragrance 4: Peppermint oil (manufactured by Nagaoka Sangyo Co., Ltd.) (Lipophilic solvents) Solvent 1: Cocoa butter ML (C8 / C10 / C12 fatty acid triglyceride, manufactured by Kao Corporation) Solvent 2: Olive oil (Extra Virgin Olive Oil: manufactured by Agroalimentaria MUSA S.L)

[0089] <Evaluation of Storage Stability (Weight Loss Rate in December)> 30 g of the manufactured capsules were put into a No. 6 bottle and stored in an environment of 40 °C and relative humidity of 75% without capping. The weights of the capsules after 4, 8, and 12 months were measured. The weight loss rate (%) in December was calculated from the weight difference of the capsule weight (W C12 ) after 12 months with respect to the weight (W C0 ) before capsule storage. Weight loss rate of capsules in December (%) = (W C12 - W C0 ) / W C0 ×100 In the measurement of the weight of the capsule, humidity conditioning was performed for 24 hours in a thermo-hygrostat layer at a temperature of 25°C and a relative humidity of 45% to make the moisture content of the film constant. The results are shown in Tables 3 to 5. The film ratio of the capsules shown in Table 3 was about 7% by weight, the film ratio of the capsules shown in Table 4 was about 11% by weight, and the film ratio of the capsules shown in Table 5 was about 15% by weight.

[0090] [Table 3] [Table 4] [Table 5]

[0091] From Tables 3 to 5 above, it was confirmed that the capsules of the examples in which the capsule film contains polysaccharides, the thickness (TH) of the capsule film is 60 μm or more, and the volatile amount (VC) of the content in 4 hours is 3.0% by weight or more have a small weight reduction rate in 12 months and are excellent in storage stability. Further, in these capsules, the breaking strength per capsule diameter is in the range of 3 to 8 N / mm, and they burst when pressure is applied with a finger. These capsules can be enclosed in the filter of a smoking device and burst by applying pressure on the filter. On the other hand, when the volatile amount (VC) of the content in 4 hours is 3.0% by weight or more and the thickness (TH) of the capsule film is less than 60 μm (A4 to A7, A9), it was confirmed that the 12-month reduction rate is large and the storage stability is poor. When the volatile amount (VC) of the content in 4 hours is less than 3.0% by weight, even when the thickness (TH) of the capsule film is less than 60 μm (A3, A8, A10), the 12-month reduction rate tended to be relatively small.
