The description of the constituent requirements described below is based on representative embodiments or specific examples, but the present invention is not limited to such embodiments. In addition, the numerical range represented by "~" in this specification means the range which includes the numerical value described before and after "~" as a lower limit and an upper limit.

[Aroma Capture System] The aroma capture system of the present invention has a humidification gas generating unit, an animal and plant raw material storage unit, and an aroma component capture unit in sequence, The animal and plant raw material storage part communicates with the humidification gas generation part and the aroma component capture part, The humidified gas generating unit generates humidified air or inert gas, that is, humidified gas, The aroma component trapping part contains an adsorbent. According to this configuration, it is possible to more efficiently capture the original aromas of animals and plants, and to obtain a natural aromatic liquid. The novel aroma trapping method developed by the inventors of the present invention is sometimes referred to as "the improved method of Japanese Patent Laid-Open No. 2000-53992". The improved method of Japanese Patent Application Laid-Open No. 2000-53992 is different from the air-liquid method (previous method) in that the aroma components are adsorbed on the adsorbent. As a result, the aroma capture can be improved without using a cooling trap. collection efficiency. When a specific humidified gas such as humidified air is forcibly brought into contact with animal and vegetable raw materials, the humidified gas will fully contain the original aroma of the animal and vegetable raw materials. Although the reason is not certain, it is presumed that the humidified gas stimulates the animal and plant raw materials so that the animal and plant raw materials are in a state where they are easy to emit fragrance, or that the water vapor is repeatedly attached and volatilized at the fragrance-emitting parts of the animal and plant raw materials, and the result is like a room. The effect of steam distillation at low temperature. Based on the above mechanism, it is speculated that by using specific humidified gas and adsorbent in the aroma capture system of the present invention, the original aroma of animals and plants can be captured more efficiently, and a natural aroma liquid can be obtained. Hereinafter, preferred aspects of the present invention will be described.

＜The overall composition of the aroma capture system＞ Referring to the drawings, the overall structure of the aroma trapping system of the present invention will be described. Fig. 1 is a schematic diagram of an example of the aroma trapping system of the present invention. The aroma trapping system of the present invention at least includes a humidifying gas generating part 2, an animal and plant raw material storage part 3, and an aroma component trapping part 5 in sequence, and an animal and plant raw material storage part 3, a humidifying gas generating part 2, and an aroma component trapping part 5 connected. With this kind of integrated aroma collection system, the humidified air or inert gas can be forced to contact the animal and plant raw materials, so that the humidified gas contains aromatic components, and the humidified gas is led out from the animal and plant raw material storage part, so that Aroma components are adsorbed to the adsorbent, thereby trapping aroma. Furthermore, for the adsorbent with aroma components, the organic solvent (diethyl ether, etc.) can be used to desorb the aroma components, and if necessary, concentrate, etc., to obtain the aroma liquid (aroma concentrate), but the desorption and concentration are not shown. in the diagram.

An example of the aroma trapping system shown in Figure 1 is a preferred form of the aroma trapping system of the present invention. Hereinafter, with reference to FIG. 1 , a preferred form of the aroma trapping system of the present invention will be described, but the description of FIG. 1 does not limit the present invention. In FIG. 1 , the air blower 1 and the exhaust fan 8 are respectively fixed on a stand 10 . In FIG. 1 , the air 11 outside the aroma collection system is introduced into the humidified gas generator 2 by the blower 1 , and the humidified gas 12 is generated by the humidified gas generator 2 . It is preferable to provide a purification unit 9 between the air blower 1 and the humidified gas generating unit 2 . The humidified gas generator 2 includes clean water 7 such as pure water, and generates a humidified gas 12 by passing the gas 11 through the water 7 . In FIG. 1 , the humidified gas generator 2 is fixed to a part of the animal and plant material 4 via a fixing member 21 . The humidified gas 12 generated in the humidified gas generating unit 2 is introduced into the animal and plant raw material storage unit 3 and forcibly contacts the animal and plant raw material 4 (in FIG. 1 , a branch of Oshima cherry blossoms). The animal and plant raw material storage part 3 has a gas inflow port 31 connected to the humidified gas generating part 2, a bag mouth part 32 that can be fixed in a state of contacting a part of the animal and plant raw material 4 (branch of Oshima cherry tree), and is connected to the aroma component trap. Gas outlet 33 of section 5. The humidified gas 12 contacting the animal and plant raw materials 4 inside the animal and plant raw material storage part 3 is sucked by the exhaust fan 8, exported from the animal and plant raw material storage part 3, and introduced into the aroma component collection part 5. The guided humidified gas 12 passes through the adsorbent 6 contained in the aroma component collecting part 5 , and at this time, the aroma component contained in the humidified gas 12 containing the aroma (aroma component) of animal and plant materials is adsorbed by the adsorbent 6 . The humidified gas 12 passing through the adsorbent 6 is sucked by the exhaust fan 8 , exported from the aroma component collecting part 5 , and discharged to the outside of the aroma capture system through the exhaust fan 8 .

Also, the aroma trapping system shown in Figure 1 can be scaled up and used in industry. For example, the animal and plant raw material storage part can also be made into a closed type, and the interior can be made into a multi-stage type, and animal and plant raw materials can be placed in each stage, so as to obtain more aromatic liquid.

The material of each part of the aroma collection system is not particularly limited, but it is preferably one that has no peculiar smell or that will not produce peculiar smell due to humidified gas. For example, resins such as PEP (polyethylene-propylene), acrylic resin, metals such as stainless steel, glass, and the like can be illustrated. Hereinafter, preferred aspects of each part of the aroma trapping system will be described.

<Blower and Exhaust Fan> The blower and exhaust fan are not particularly limited. Ordinary pumps can be used. The flow rate (supply air volume) of the air blown by the blower can also be changed according to the aroma trapping target and the size of the aroma trapping system. For example, when the aroma of flowers, fruits or herbs is captured, the air volume is preferably 0.1-10.5 L/min, more preferably 0.5-5.5 L/min, and most preferably 1.0-3.5 L/min. On the other hand, the flow rate (exhaust air volume) of the gas exhausted by the exhaust fan can be set according to the air supply volume. For example, the exhaust air volume is preferably 0.1-10 L/min, more preferably 0.5-5 L/min, and most preferably 1.0-3.0 L/min. From the viewpoint of sufficiently adsorbing aroma components to the adsorbent, the air supply and exhaust air volumes are preferably equal to or greater than the lower limits. From the point of view of inhibiting the humidified gas from passing through the adsorbent before the aroma components are adsorbed on the adsorbent, it is easy to make the aroma components adsorb on the adsorbent, and from the viewpoint of suppressing the load applied to the flow path from the blower to the exhaust fan so that it is difficult to deviate from the flow path. In other words, it is preferable that the air supply volume and the exhaust air volume be below these upper limits. It is preferable that the blowing air volume is the same as the exhaust air volume when sealing between the bag opening of the animal and plant material storage part and the animal and plant material. On the other hand, in the case of unsealed between the bag opening of the animal and plant raw material storage part and the animal and vegetable raw material, it is preferable to make the air supply volume larger than the exhaust air volume. A pocket is provided at the part (end, etc.) outside the flow path from the gas inlet to the gas outlet of the animal and plant raw material storage part, so that the air supply volume is greater than the exhaust air volume, so that the humidified gas can be used as the main gas. The gas inlet of the flexible bag leads to the gas outlet. In addition, it is possible to suppress the gas from outside the system from flowing into the animal and plant raw material storage part from the mouth of the bag, and capture the smell of the gas from outside the system. Air supply or exhaust can be continuous or interrupted midway. From an industrial point of view, it is better to stop the air supply or exhaust, and replace the animal and plant raw materials (such as cut flowers, etc.) with fresh ones, and then start capturing again, so as to capture the aroma of animal and plant raw materials for several days. The air blower and the exhaust fan can also be installed on a platform, etc., and fixed at a height of more than 1 m from the ground (preferably within a range of 1 to 3 m from the ground). It can be preferably applied to the situation where the raw materials of animals and plants are plants at a height of more than 1 m from the ground.

<Humidified gas generator> In the present invention, the humidified gas generator generates humidified air or inert gas that is humidified gas. The humidified gas generated by the humidified gas generating part is introduced into the animal and plant raw material storage part to make it contact with the animal and plant raw material. By using humidified gas, it is easy to capture the original aroma of animal and plant raw materials.

(Humidified gas) Humidified gas is humidified air or inert gas. As the air, the air outside the aroma trapping system can be used. As the inert gas, helium, nitrogen, argon, etc. can be used, but nitrogen is the most economical and useful. Furthermore, the use of air or inert gas needs to be properly selected according to the animal and plant raw materials to capture aroma. For example, when the animal and plant raw materials are flowers or fresh fruits (flowers or fruits of growing plants that absorb nutrients from their roots) and cut flowers, it is preferable to use air so that the animal and plant raw materials do not become anoxic and wither.

The humidity of the humidified gas is preferably higher than the humidity outside the place where the aroma trapping system is installed. When the humidified gas is introduced as the humidified gas, it is preferable that the temperature of the humidified gas is the same as that of the air outside the system, and that the humidity of the humidified gas is higher than that of the humidified gas outside the system. of air. On the other hand, when an inert gas is introduced as the humidified gas, it is preferable that the temperature of the humidified gas is adjusted so as to be the same temperature as the outside air, and that the humidity of the humidified gas is preferably high. The air outside the system. The humidity of the humidified gas is preferably 40-100%, more preferably 60-100%, and most preferably 80-100%. The temperature of the humidified gas is preferably higher than 0°C and lower than 50°C, more preferably 15-45°C, especially preferably 20-40°C. From the point of view that it is difficult to change the aroma of animal and plant raw materials due to heating, etc., it is preferably below 50°C. Preferably it is below 40°C. From the viewpoint of increasing the humidity, it is preferably more than 0°C, and from the viewpoint of easy preparation of humidified gas with a humidity of 80% or more, it is preferably 15°C or more. In particular, the use of air with a temperature of 15-40°C and a humidity of 80% or more is a good condition for maintaining the freshness of cut flowers, so it can withstand long-term aroma capture without the cut flowers withering.

<Purification part> It is preferable to install a purification part on the upstream side of the animal and plant raw material storage part to purify the gas outside the system. By installing the purification unit, it is possible to capture the weak aroma that contributes to the original aroma of animals and plants, and it does not capture other various volatile components that exist in the atmosphere outside the system. The purification part of the gas outside the system can be installed between the outside of the system and the blower, between the blower and the humidified gas generating part, etc. However, the humidified gas purification unit may be installed between the humidified gas generation unit and the animal and plant raw material storage unit. It is preferable to install an external gas purification unit between the air blower and the humidified gas generating unit. A purification unit can also be installed between the outside of the system and the blower as needed, but it is better to install a purification unit directly in front of the humidified gas generating unit, so as to clean the external gas (air or inert gas) introduced into the humidified gas generating unit. Purify. The purification part is preferably a filling part of a material that contributes to deodorization and the like. It does not specifically limit as a material which contributes to deodorization etc., For example, the material used for the following adsorbent is mentioned. From the viewpoint of capturing efficiency of volatile components, activated carbon is more preferable.

<Animal and plant material storage unit> The animal and plant material storage unit is not particularly limited as long as it can store animal and plant material. It is preferable to freely store and take out animal and plant raw materials.

(Animal and plant raw materials) The animal and plant raw materials are not particularly limited, and may be animals or plants. In the present invention, the animal and plant raw material is preferably at least a part of a plant. However, animal and plant raw materials may also be non-viable plants or materials derived from animals. Examples of non-growing plants include cut flowers, harvested fruits, processed plants (such as roasted coffee beans, teas such as black tea, plants used for spices and Chinese medicines), and the like. Examples of animal-derived materials include fish and shellfish, livestock meat, and processed foods thereof.

At least a part of the plant used as animal and plant raw materials is preferably at least one of flowers, flower buds, vegetables, herbs, trees, bark, branches, leaves, buds, roots, and fruits (in this specification, false fruits such as strawberries are also included) kind. Two or more of these may be used, for example, flowering branches. Among these, flowers, flower buds, herbs, and fruits are more preferable from the viewpoint of analyzing the fragrance liquid of the present invention and applying the blended fragrance of the present invention described below to fragrance or perfume use. Examples of flowers and flower buds include potted flowers such as rose, lily of the valley, jasmine, lily, gardenia, orchid, and narcissus; flowers of trees such as cherry blossom, plum blossom, wisteria, magnolia, magnolia, and osmanthus. Examples of vegetables include vegetables used in Chinese medicine, such as lily root, licorice, turmeric, pepper, and Korean ginseng. In addition, the term "vegetables" is a general term for herbs used as side ingredients, and root vegetables such as carrots are also included in vegetables. Examples of trees and bark include those that produce aroma, such as Ceylon cinnamon, cedar wood, agarwood, and canain. Branches, leaves, and buds are not particularly limited, and may be those that produce fragrance alone or those that do not produce fragrance alone (parts that mainly do not produce fragrance, such as branches with flowers). Examples of the root include vetiver orris root and the like. Examples of herbal medicines include plants used for spices such as mint, lemongrass, geranium, thyme, lavender, and basil. Examples of the fruit include strawberries, apples, peaches, tangerines, and pears.

The present invention can efficiently capture the original aroma of animals and plants even without using a cooling trap, so it can be especially applied to flowers of trees, larger flowers in potted flowers, etc. Specifically, it can also be applied as raw materials of animals and plants At least a part of the plant used exists at a distance of 1 m or more (for example, about 1 to 3 m) from the ground. In addition, the present invention can efficiently capture the original aroma of animals and plants without using a cooling trap, so it can be applied to plants grown outdoors. In this case, the animal and plant raw material storage part may be fixed at a height of 1 m or more from the ground. Furthermore, the present invention can also be applied to the case where the animal and plant raw material is a plant with a height less than 1 m. In this case, the position of the aroma component trapping part is not limited. Examples of plants whose animal and plant raw materials are less than 1 m include strawberries, basil, and the like.

(Characteristics of the Animal and Plant Material Storage Section) The animal and plant material storage section preferably has flexibility. Due to the flexibility of the animal and plant raw material storage part, it can more efficiently capture the target aroma of animal and plant raw materials in a natural environment. In particular, the target aroma of animal and plant raw materials can only be used in specific situations (when the aroma is strongly produced during growth) and at a specific time (in the case of flowers that produce aroma at a certain time during the day; flowers that bloom at night, such as epiphyllum, are difficult to achieve). When it is collected artificially according to the timing of flowering), it is easy to obtain the target aroma when it is obtained under specific conditions (such as herbs that are stimulated to produce aroma), etc. Specifically, a flexible bag is preferable as the flexible animal and plant raw material storage unit. There are no special restrictions on the material used as the animal and plant raw material storage part. For example, resin, metal, glass are mentioned. Among them, flexible resin or metal is preferable. Examples of the resin include vinyl alcohol-based polymers, polyvinyl fluoride, polyvinylidene fluoride, and polyethylene. Examples of the metal include aluminum and stainless steel. Among them, the material of the animal and plant raw material storage part is preferably a vinyl alcohol-based polymer. For example, "Smart Bag PA" manufactured by GL Sciences Co., Ltd. is exemplified as an example of a flexible bag of a vinyl alcohol-based polymer.

(Structure of animal and plant raw material storage part) The animal and plant raw material storage part can be a partially open container as shown in Figure 1, or a closed container, which can be used according to the target. For example, in the case of growing animal and plant raw materials, it is preferable to use a partially open container, and in the case of non-growing animal and plant raw materials, it is preferable to use a closed container. Hereinafter, the case where the animal and plant material storage part is a flexible bag is taken as a representative example, and the preferable form of the structure of the animal and plant material storage part is demonstrated. The flexible bag is preferably a partially open container. Specifically, the flexible bag preferably has a gas inflow port connected to the humidified gas generating part, a bag opening that can be fixed in a state of contacting at least a part of animal and plant raw materials, and a gas port connected to the aroma component trapping part. outlet. A part of the bag mouth can be opened between the bag mouth and the animal and plant raw materials, but it can also be sealed (sealed) to improve the capture efficiency of the aroma components.

<Aroma Component Capture Unit> The aroma component capture unit is not particularly limited as long as it contains an adsorbent. General column etc. which can be filled with an adsorbent are mentioned. In the present invention, the temperature of the aroma component trapping portion is preferably higher than 0°C. Furthermore, it is more preferable that the minimum temperature in the flow path from the animal and plant raw material storage part to the aroma component trapping part is more than 0 degreeC. There is substantially no cooling trap in the flow path from the animal and plant raw material storage part to the aroma component trapping part, so that the aroma absorption amount by the adsorbent can be increased. Furthermore, by making the minimum temperature in the flow path from the animal and plant raw material storage part to the aroma component trapping part exceed 0°C, freezing of moisture in the humidified gas can be suppressed, and blockage of the flow path can be suppressed. An aspect in which the aroma component trapping part is fixed at a height of 1 m or more from the ground may also be used. It can be preferably applied to the case where the animal and plant raw materials are plants at a height of more than 1 m from the ground.

(Adsorbent) The adsorbent is not particularly limited. For example, silica gel, porous resin, activated carbon, etc. are mentioned. Examples of the porous resin include 2,6-dimethyl-p-phenylene ether polymers, 2,6-biphenylene-p-phenylene ether polymers, acrylate polymers, styrene divinylbenzene polymers, and the like. The adsorbent can be a hydrophobic adsorbent or a hydrophilic adsorbent, but is preferably a hydrophobic adsorbent. The adsorbent more preferably comprises a 2,6-biphenylene-p-phenylene ether polymer. The mesh number of the porous adsorbent is not particularly limited. The amount of the adsorbent filled in the aroma component trap is not particularly limited.

<Using method of the aroma trapping system> In a preferred embodiment of the aroma trapping system, the entire aroma trapping system may be installed outdoors. This method of use is particularly preferred when the animal and plant raw materials are trees. In the method described in Japanese Patent Laid-Open No. 2000-53992, in order to improve the efficiency of aroma capture, cooling traps (freezing wells, traps cooled by dry ice in ethanol, liquid nitrogen cooling traps) are required. Well) for long-term aroma capture, it is difficult to carry out long-term aroma capture outdoors. Therefore, in the method described in Japanese Patent Application Laid-Open No. 2000-53992, plants in the state of potted or cut flowers are placed in a device installed indoors to trap aroma. Depending on the type of plant (flower), the aroma emitted when the cut flower is made changes, resulting in a situation where the aroma concentrate obtained by the previous method is different from the original aroma of the plant. In contrast, according to a preferred embodiment of the present invention, for plants growing outdoors, headspace air aroma capture using humidified gas can also be carried out for a long time without harming the plants, so as to obtain Aroma concentrate of the original aroma of the plant (flower). However, a part or the whole of the aroma trapping system may be installed indoors. This method of use is particularly preferable when the animal and plant raw materials are potted plants, plants whose fragrance does not change even when they are cut flowers, harvested fruits, and the like.

[Aroma Trapping Method] The aroma trapping method of the present invention includes a step of introducing the humidified gas generated by the humidified gas generating unit into the animal and plant raw material storage unit to contact the animal and plant raw material, and The stage where the gas containing the aroma of animal and plant raw materials is introduced into the aroma component capture part to capture the aroma component, Humidified gas is humidified air or inert gas, The aroma component trapping part contains an adsorbent. Hereinafter, preferred aspects of the aroma trapping method of the present invention will be described.

<Stage of preparing humidified gas> The aroma trapping method preferably includes a step of introducing air or an inert gas into a humidified gas generator to prepare humidified gas. The method of generating the humidifying gas is not particularly limited. For example, it can be produced by blowing air or an inert gas into a solvent containing water. The solvent containing water is preferably water with less volatile components other than water, more preferably odorless clean water, and most preferably ultrapure water (so-called Milli-Q water). The stage of preparing humidified gas is preferably a stage of introducing air or inert gas into water. Furthermore, when a humidification gas purification unit (for example, an activated carbon filling unit) is installed between the humidification gas generation unit and the animal and plant raw material storage unit, the solvent containing water may contain any volatile components or non-volatile components. Element. The temperature of the water used is not particularly limited, for example, it can be set at 0-50°C, preferably 15-45°C, more preferably 20-40°C. In the present invention, it is preferable that the step of preparing the humidified gas is a step of introducing external air to the humidified gas generating unit, and that the humidity of the humidified gas is higher than the humidity outside the system.

<Stage of storing animal and plant raw materials> It is preferable that the aroma trapping method includes a stage of storing animal and plant raw materials. There is no particular limitation on the method of storing animal and plant raw materials. In the case of using a partially open container such as a flexible bag with a mouth, a part or the whole of animal and plant raw materials can be stored inside the flexible bag, and fixed in a state where a part of the mouth is opened. It is in an open state, but the mouth of the bag can also be closed (sealed) if necessary. In the case of using a closed container such as a glass container with a lid and a main body, the animal and plant raw materials can be housed in the main body of the container and then sealed with a lid to make it airtight.

<Stage of giving stimulus> In a preferred embodiment of the aroma trapping method, it is preferable that the animal and plant raw material storage part is a flexible bag, and includes deforming the flexible bag so that at least a part of the growing plant is deformed. The stage of giving stimulation. A method in which a growing plant is stimulated by deforming a flexible bag to positively produce an aroma from an animal or plant material can be performed. This method cannot be easily realized in the case of the method described in Japanese Patent Laid-Open No. 2000-53992 (the case where the animal and plant raw material storage part does not have flexibility). In particular, when stimulation is given multiple times and/or for more than 2 seconds to animal and plant raw materials, stimulation can be easily given by using a flexible bag.

<Stage of Trapping Aroma Components> The aroma trapping method preferably includes a stage of trapping aroma components. The method of trapping aroma components is not particularly limited. Aroma components can be captured by introducing humidified gas derived from the animal and plant raw material storage unit into the aroma component capture unit including the adsorbent. In the present invention, it is preferable to use an exhaust fan to suck the humidified gas, so as to forcibly lead it out from the animal and plant raw material storage part. The capture time is not particularly limited. In the present invention, since the aroma trapping efficiency can be improved without using a cooling trap, it is possible to trap aroma components easily and at low cost for a long time. Especially in the case of capturing aroma components outdoors, it is possible to capture aroma components for a long time at low cost. Therefore, the capture time may be set to, for example, 3 hours or more, or may be set to 5 hours or more as necessary.

<Stage of Obtaining Aroma Liquid> The aroma trapping method preferably includes a stage of passing an organic solvent through the adsorbent to obtain an aroma liquid containing aroma components. Passing an organic solvent into an adsorbent is also called desorption. As the organic solvent, hydrocarbons such as pentane, ethers, and the like can be used, and one or more organic solvents can be used as needed. In the step of obtaining the aromatic liquid, it is preferable to further refine, wash, and concentrate the desorbed liquid obtained by passing an organic solvent through the adsorbent.

[Fragrance Liquid] The fragrance liquid of the present invention is obtained by the aroma trapping system of the present invention or the aroma trapping method of the present invention. The fragrance of the fragrance liquid of the present invention is like the fragrance of flowers floating in the morning mist, reproducing the "fresh" fragrance as described in the text. The aroma liquid of the present invention is useful for the analysis and research of aroma components. It can be analyzed by combining gas chromatography (GC) and mass spectrometry (MS) (abbreviated as GC-MS), or it can be used for sensory evaluation, or it can be used for fragrance adjustment with reference to aroma . The gas chromatograph used by the GC is preferably equipped with a flame ionization detector (Flame Ionization Detector, FID), and it is preferably combined with a mass spectrometer for GC-MS/FID analysis. Moreover, the fragrance liquid of this invention can be used for the fragrance composition of this invention mentioned later. On the other hand, the fragrance liquid of the present invention can be used in industries such as cosmetics and fragrances.

Therefore, the scope of the present invention should not be limitedly interpreted by the specific examples shown below.

[Example 1] <Oshima cherry blossoms, outdoors, improved method of Japanese Patent Laid-Open No. 2000-53992 (aroma trapping method of the present invention)> The aroma trapping method of the present invention is implemented by using the aroma trapping system of the present invention illustrated in FIG. 1 . The aroma capture system used is composed of blower, purification part, humidified gas generation part, animal and plant raw material storage part, aroma component capture part and exhaust fan connected in sequence. Arrange and fix each part separately outdoors at a height of 1-3 m from the ground. In addition, the air blower and the exhaust fan are fixed on the stand, the humidified gas generating part is fixed to a part of the animal and plant material through the fixing member, and the animal and plant material storage part is fixed to the animal and plant material by the following method. Use pumps as blowers and exhaust fans. The humidification gas generator described in [0018] of Japanese Patent Laid-Open No. 2000-53992 was used as the humidification gas generator. Arrange odorless clean water in the humidified gas generator, and supply humidified gas by introducing gas into the water to make it bubble. Furthermore, activated carbon as a purifying part of the extrasystem gas is disposed at the entrance of the humidified gas generating part. A flexible vinyl alcohol-based polymer bag ("Smart Bag PA" manufactured by GL Sciences Co., Ltd.) was used as the animal and plant raw material storage unit. The flexible bag is provided with a gas inflow port connected to the humidified gas generating part, a bag mouth part, and a gas discharge port connected to the aroma component trapping part. Oshima cherry blossoms grown outside Kanagawa Prefecture are used as animal and plant raw materials. Oshima Sakura is a variety that releases a light fragrance from its petals. A column filled with an adsorbent is used as an aroma component trapping section. Tenax TA (2,6-biphenylene-p-phenylene ether polymer), 35/60 mesh, 2.0 g was used as the adsorbent.

A part of the branch of about 20 Oshima cherry blossoms is wrapped and stored in a flexible bag, and fixed in an unsealed state with the opening of the bag slightly touching the branch. Humidified air is obtained by supplying the air outside the system to the humidified gas generator by the blower. Introduce the obtained humidified air into the gas inflow port of the flexible bag (arranged on the vertically upper surface of the flexible bag and on the vertically lower side than the mouth of the bag), and place the top of the flexible bag The air is sucked and discharged from the gas outlet (arranged on the bottom surface of the flexible bag on the opposite side to the bag opening) through the aroma component trapping part and exhausted by the exhaust fan. According to this step, the gas mainly composed of humidified air passes from the gas inflow port of the flexible bag to the gas discharge port, thereby trapping aroma components in the adsorbent. Again, no cooling trap is used. Other conditions are described below. ·Flow rate: air supply (humidification gas) 3.0 L/min, exhaust air (suction) 2.5 L/min. ·Catching time: 3 hours during the daytime in April. ·Temperature (external): 19~21℃. ·Temperature (within the system): Same as outside the system. The temperature of the humidified gas generating part and the aroma component trapping part is also not controlled. Secondly, 20 mL of diethyl ether was passed into the adsorbent to desorb the aroma components. The desorbed solution was dehydrated with Glauber's salt (Na ₂ SO ₄ ·10H ₂ O), filtered through filter paper, and concentrated at 43°C under normal pressure to obtain the aroma liquid (aroma concentrate) of Example 1. The fragrance liquid of Example 1 was used for GC-MS/FID analysis.

[Comparative example 1] <Oshima cherry tree, outdoor, DHS method> In addition to not using a blower and a humidified gas generating unit, supplying humidified gas, and opening the gas inlet to the outside air without passing through activated carbon as a purification unit for outside air, the same procedure as in Example 1 was performed. The aroma trapping method of Comparative Example 1 was carried out in the same manner. The obtained aromatic liquid was subjected to GC-MS/FID analysis in the same manner as in Example 1. Furthermore, the pump only performs exhaust (suction), and the flow rate of the exhaust is set to 2.5 L/min. ·Catching time: 3 hours during the daytime in April.

[Comparative example 2] <Oshima cherry tree, indoor, liquid air method (previous method)> Using the flowers and branches of Oshima Sakura (the same tree as in Example 1) were cut together and inserted into ultrapure water (Milli-Q water) (cut branches) as animal and plant raw materials, and used Japanese Patent Laid-Open No. 2000-53992 indoors The device described in Figure 1 of the publication uses the air-liquid method (previous method) for aroma capture. A glass container is used as an animal and plant sample storage unit. The glass container is provided with a gas inlet connected to the humidified gas generating part through the purification part (arranged on the side of the vertical upper part of the glass container), and a gas outlet connected to the aroma component collecting part (arranged at the vertical lower part of the glass container) side) and enable other parts to be sealed. Use 2 pumps to introduce humidified air and suck the headspace gas under the following conditions, and use a cooling trap (a trap cooled by putting dry ice in ethanol) to trap aroma components to obtain a condensate (5.1 g). ·Flow rate: air supply (humidification gas) 2.5 L/min, exhaust air (suction) 2.5 L/min. ·Catching time: 3 hours during the daytime in April. After the condensate (5.1 g) was recovered, the entire wall of the cooling trap was washed with 20 mL of diethyl ether, and the entire amount of the obtained liquid (the liquid obtained after washing) was mixed with the condensate. After adding and dissolving 0.8 g of sodium chloride to the obtained mixed solution, liquid separation was performed, and the aqueous layer was extracted twice with 5 mL of ether. The ether layer was dehydrated with Glauber's salt, filtered through filter paper, and concentrated at 43°C under normal pressure to obtain the aroma liquid (aroma concentrate) of Comparative Example 2. The obtained aromatic liquid was subjected to GC-MS/FID analysis in the same manner as in Example 1.

[Comparative example 3] <Oshima cherry tree, indoor, DHS method> Aroma trapping of comparative example 3 was carried out using the DHS method using the flowers and branches of Oshima cherry (the same tree as in Example 1) which were cut together and inserted into ultrapure water (Milli-Q water) (cut branches) as animal and plant raw materials method. A glass container is used as an animal and plant sample storage unit. The glass container is provided with a gas inlet connected to the outside air through the purification part (arranged on the side of the vertical upper part of the glass container), and a gas outlet connected to the aroma component collecting part (arranged on the vertical lower part of the glass container) side), and enable other parts to be sealed. The aroma liquid (aroma concentrate) of Comparative Example 3 was obtained by introducing air and sucking the headspace gas using one pump under the following conditions to collect the aroma. The obtained aromatic liquid was subjected to GC-MS/FID analysis in the same manner as in Example 1. Furthermore, the pump only performs exhaust (suction), and the flow rate of the exhaust is set to 2.5 L/min. ·Catching time: 3 hours during the daytime in April.

[Evaluation] <Sensory Evaluation> For the fragrance liquids (aroma concentrates) of Example 1 and Comparative Examples 1-3, 10 well-trained professional sensory inspectors conducted sensory evaluation. The results are shown below. Evaluation criteria: "The best aroma" or "most similar to the aroma of Oshima cherry blossoms" is scored as 10 points, and the "worst aroma" or "least similar to the aroma of Oshima cherry blossoms" is scored as 0 points. The average person was scored as 5 points, and the 11-level evaluation was scored in units of 1 point, and the functional characteristics were described. The average score and the average sensory evaluation of the evaluation scores of 10 professional sensory inspectors are shown in Table 1 below.

According to the above Table 1, the fragrance liquid obtained by carrying out the aroma trapping method on the Oshima cherry blossoms (cut branches) of Comparative Examples 2 and 3 can experience negative aromas such as metallic feeling like perilla and stuffy smell. In Example 1 and Comparative Example 1, the aromatic liquid obtained by carrying out the method of trapping the aroma of Oshima cherry blossoms growing outdoors can not feel the negative aroma. Compared with Comparative Example 1, Example 1 is more natural. The aroma of cherry blossoms also has a higher average score.

<Aroma Components> Table 2 shows the abundance ratio (GC-Area%) of the main aroma components of the GC-MS/FID analysis results of the aroma liquids (aroma concentrates) of Example 1 and Comparative Examples 1-3.

[Table 2]

According to the above Table 2, in Example 1, linalool (linalool) with a fresh and floral fragrance and 2-phenylethanol (2-phenylethanol) like a rose were detected at a rate higher than that of Comparative Examples 1 to 3, and then at a rate higher than that of Comparative Examples The ratios of Examples 2 and 3 detected anisaldehyde and methyl anisate like anise.

＜Summary of evaluation results of Oshima cherry blossoms＞ Regarding the aroma capture method of Oshima cherry blossoms, if the aroma capture of cut flowers is carried out using the liquid air method (previous method) of Comparative Example 2, a stuffy smell (fatty smell) is obtained Aroma liquid (aroma concentrate). On the other hand, it is clear that by using the aroma trapping system and the aroma trapping method of the present invention, it is possible to obtain a fragrance liquid (aroma concentrate) with a floral fragrance closer to the real thing and with a natural feeling. Based on the above evaluation results, regarding the method for capturing the aroma of Oshima cherry blossoms, it is considered that the aroma capturing method of the present invention carried out outdoors in Example 1, that is, the aroma of the improved method of Japanese Patent Laid-Open No. 2000-53992 Capture methods are more effective.

[Example 101] <Red cheeks, indoor, improved method of Japanese Patent Laid-Open No. 2000-53992 (aroma trapping method of the present invention)> The aroma trapping system used in Example 1 with the following changes was used as the aroma trapping system of Example 101, and the aroma trapping system of Example 101 was used to implement the aroma trapping method of the present invention. Use a glass container as a storage unit for animal and plant raw materials. The glass container is provided with a gas inlet connected to the humidified gas generating part (placed on the side of the vertically lower part of the glass container), and a gas outlet connected to the aroma component collecting part (placed on the vertically upper cover of the glass container) , and enable other parts to be sealed. Configure and fix the entire aroma capture system indoors at a height of 1-2 m from the ground. Furthermore, the air blower, the exhaust fan, and the humidified gas generating unit are fixed on the table, and the animal and plant material storage unit is fixed on the table in a state of covering the animal and plant material. Strawberries (red cheeks, those with false fruit parts and pedicle parts) are used as animal and plant raw materials. Tenax TA (2,6-biphenylene-p-phenylene ether polymer), 60/80 mesh, 2.0 g was used as the adsorbent.

Put 8 red cheeks into the inside of the glass container, and seal the parts except the gas inflow port and the gas discharge port. Humidified air is obtained by supplying the air outside the system to the humidified gas generator by the blower. Introduce the obtained humidified air into the gas inlet of the glass container (arranged on the side of the lower part of the glass container), and pass the headspace gas of the glass container through the gas outlet (arranged on the vertical upper cover of the glass container) through the aroma The component collection part is sucked and discharged by the exhaust fan. According to this step, aroma components are trapped on the adsorbent. Again, no cooling trap is used. ·Flow rate: air supply (humidification gas) 1.5 L/min, exhaust air (suction) 1.5 L/min. · Capture time: 4 hours · Room temperature (external): 21°C ·Temperature (within the system): Same as outside the system. Also, the temperature of the humidified gas generating part and the aroma component collecting part is not controlled. Humidity: (external) 42% Next, pass 20 mL of diethyl ether into the adsorbent to desorb the aroma components. The desorbed solution was dehydrated with Glauber's salt, filtered through filter paper, and concentrated at 43°C under normal pressure to obtain 42.7 mg (including solvent) of the aroma liquid (aroma concentrate) of Example 101. The fragrance liquid of Example 101 was used for GC-MS/FID analysis.

[Reference Example 101] <Confirmation of temperature and humidity of humidified gas> On another day, the same experiment as in Example 101 was carried out. As a result, it was confirmed that the air outside the system and the air (humidification gas) introduced into the system reached the following temperatures and humidity respectively. That is, it is known that the temperature of the humidified gas is the same as the temperature outside the place where it is installed, and the humidity of the humidified gas is higher than the humidity outside the place where the aroma trapping system is installed. ＜At the beginning＞ Outside the system: 17.3°C, humidity 47% Inside the system: 17.3°C, humidity 47% ＜After 60 minutes＞ Outside the system: 17.9°C, humidity 51% Inside the system: 17.9°C, humidity 85%

[Comparative Example 101] <Red cheeks, indoor, liquid-air method (previous method)> Using 8 red cheeks as animal and plant raw materials, the device described in Figure 1 of Japanese Patent Laid-Open No. 2000-53992, which is the same as Comparative Example 2, was used indoors to capture aroma by liquid air method (previous method). A glass container is used as an animal and plant sample storage unit. Use 2 pumps to introduce humidified air and suck the headspace gas under the following conditions, and use a cooling trap (a trap cooled by putting dry ice in ethanol) to trap aroma components to obtain a condensate (4.7 g). ·Flow rate: air supply (humidification gas) 1.5 L/min, exhaust air (suction) 1.5 L/min. · Capture time: 4 hours · Room temperature (external): 21°C ·Temperature (within the system): Same as outside the system. Also, the temperature of the humidified gas generating part and the aroma component collecting part is not controlled. After recovering the condensate (4.7 g), wash the entire wall of the cooling trap with 20 mL of diethyl ether, and mix the entire amount of the obtained liquid with the condensate. After adding and dissolving 0.7 g of sodium chloride to the obtained mixed solution, liquid separation was performed, and the aqueous layer was extracted twice with 5 mL of ether. The ether layer was dehydrated with Glauber's salt, filtered through filter paper, and concentrated at 43°C under normal pressure to obtain 42.9 mg (including solvent) of the aroma liquid (aroma concentrate) of Comparative Example 101. The obtained aromatic liquid was subjected to GC-MS/FID analysis in the same manner as in Example 101.

[Comparative Example 102] <Red cheeks, indoor, DHS method> The aroma trapping method of Comparative Example 102 was carried out in the same manner as in Example 101, except that the humidified gas generating unit was not used and non-humidified outside air was supplied. ·Flow rate: air supply (unhumidified outside air; temperature 20°C, humidity 42%) 1.5 L/min, exhaust (suction) 1.5 L/min. · Capture time: 4 hours · Room temperature (external): 20°C Humidity (external): 42% Desorption and concentration from the adsorbent were carried out in the same manner as in Example 101, thereby obtaining 43.0 mg (including the solvent) of the aroma liquid (aroma concentrate) of Comparative Example 102. The obtained aromatic liquid was subjected to GC-MS/FID analysis in the same manner as in Example 101.

[Evaluation] <Sensory evaluation> For the samples (red cheeks) used as animal and plant raw materials, the aroma liquid (aroma concentrate) obtained in Example 101, Comparative Example 101 and Comparative Example 102, 10 well-trained professionals A sensory inspector conducts a sensory evaluation. The average results of the sensory evaluation are shown in Table 3 below.

[table 3]

According to the above-mentioned Table 3, it is evaluated that: compared with the aromatic liquid (aroma concentrate) obtained in Example 101, Comparative Examples 101 and 102, the aroma of the aromatic liquid (aroma concentrate) obtained in Example 101 is more balanced, the most It is close to the fragrance wafting from the raw materials of animals and plants (that is, a fragrance with a natural feeling). The aroma liquid (aroma concentrate) obtained in Comparative Example 101 had a weaker aroma and distinct sour and sweet tastes. The aroma liquid (aroma concentrate) obtained in Comparative Example 102 has a green and astringent aroma that is not obvious in the aroma of the sample.

＜Aroma Components＞ (The ratio of each component; GC-Area%) The GC-MS/FID analysis results (compound names of detected components) and the abundance ratio of each component of the fragrance liquid (aroma concentrate) of Example 101, Comparative Example 101 and Comparative Example 102 are shown in Table 4 below. The gas chromatograms obtained by performing GC-MS/FID analysis on the aroma liquids (aroma concentrates) obtained in Example 101, Comparative Example 101, and Comparative Example 102 are shown in FIG. 2 .

[Table 4]

According to the above table 4, compared with the improved method of Japanese Patent Application Laid-Open No. 2000-53992 of Example 101 and the air-liquid method (previous method) of Comparative Example 101, methyl butanoate, ethyl butyrate Fruit esters such as (ethyl butanoate), ethyl pentanoate (ethyl pentanoate) accounted for a higher ratio in Example 101. In addition, it was found that methyl butanethioate (S-methyl butanethioate), which has the aroma of cheese, was 0.11 GC-Area% in Example 101 and 0.02 GC-Area% in Comparative Example 101. The difference between the two is large . In addition, in Example 101, furaneol and γ-dodecalactone, which are considered to contribute to sweetness, were detected at higher rates. On the other hand, as components detected at a higher rate in Comparative Example 101, acids such as acetic acid and 2-ethylhexanoic acid, or methoxyfuranone (methoxyfuraneol ), etc., it is speculated that acids contribute to the sour taste in the sensory evaluation of Comparative Example 101, and methoxyfuraneol (methoxyfuraneol) contributes to the sweet taste. Compared with the improved method of Japanese Patent Application Laid-Open No. 2000-53992 in Example 101 and the DHS method of Comparative Example 102, multiple esters were detected at a higher rate in Comparative Example 102, which is presumed to be helpful for comparison Fruity aroma with a ripe feeling in the sensory evaluation of Example 102. Also, in Comparative Example 102, hexanal (hexanal), (Z)-acetic acid-3-hexenyl ester ([(Z)-hex-3-enyl] acetate) and (Z)- Acetate-2-hexenyl ester ([(Z)-hex-2-enyl] acetate) and other green and astringent aroma components, so it is speculated that these components contribute to the green and astringent feeling in the sensory evaluation of Comparative Example 102.

<Summary of Strawberry Evaluation Results> As for the aroma trapping method of strawberry (red cheeks), it is clear that by using the aroma trapping system and the aroma trapping method of the present invention, it is possible to obtain an aroma close to the real strawberry ( That is, a fragrance liquid (aroma concentrate) with a natural feeling. Based on the above evaluation results, regarding the method for capturing the aroma of strawberries, it is considered that the method for capturing the aroma of the present invention carried out in Example 101, that is, the method for capturing the aroma of the improved method of Japanese Patent Application Laid-Open No. 2000-53992 is better. efficient. If the surface is dry like strawberries (red cheeks), then the fragrance that floats from the surface or the fruit or fragrance that has a poor fragrance when eating, it is speculated that by using the fragrance trapping method of the present invention (Japanese Patent Laid-Open No. 2000-53992 The improved method of the Bulletin), which can more efficiently capture the original aroma of animals and plants, and obtain a natural aromatic liquid. Compared with the air liquid method (previous method), by using the aroma capture method of the present invention, it is possible to efficiently capture esters among volatile components that contribute greatly to the aroma of fruits with a balance close to the original aroma. Classes, alcohols, lactones, etc. On the other hand, it is speculated that in the DHS method without humidification, the green and astringent aroma produced by the drying pressure is more than the original aroma, and the aroma trapping method of the present invention can capture less green and astringent aroma, which is closer to The aroma of the balance of things.

Furthermore, when the aroma trapping method of the present invention (the improved method of Japanese Patent Application Laid-Open No. 2000-53992 ) and the DHS method are carried out on the strawberries (red cheeks) before picking in the houses and farmlands of the producing farmers , and the results with the same tendency as in Example 101 and Comparative Example 102 can also be obtained.

[Example 201] <basil, indoor, improved method of Japanese Patent Laid-Open No. 2000-53992 (aroma trapping method of the present invention)> The aroma trapping system used in Example 1 with the following changes is used as the aroma trapping system of Embodiment 201, and the aroma trapping system of Embodiment 201 is used to implement the aroma trapping method of the present invention. Basil (sweet basil) grown in soft plastic pots (potted seedlings) herbal medicines is used as animal and plant raw materials. Only the aboveground part of one basil plant was wrapped and accommodated in a flexible bag (Smart Bag PA), and fixed without airtightness in a state where the opening of the bag was slightly in contact with the stem (with little pressure on the basil). Humidified air is obtained by supplying the air outside the system to the humidified gas generator by the blower. Introduce the obtained humidified air into the gas inlet of the flexible bag (arranged on the vertical upper surface of the flexible bag), and discharge the headspace air of the flexible bag from the gas outlet (arranged on the flexible bag The side of the lower part of the bag and the part on the vertical upper side than the mouth of the bag) is sucked and discharged by the exhaust fan through the aroma component trapping part. According to this step, the gas mainly composed of humidified air passes from the gas inflow port of the flexible bag to the gas discharge port, thereby trapping aroma components in the adsorbent. Again, no cooling trap is used. Other conditions are described below. ·Flow rate: air supply (humidification gas) 2.5 L/min, exhaust air (suction); 2.0 L/min. · Capture time: 6 hours · Tap the flexible bag from the outside for 1 minute every 30 minutes, thereby stimulating the basil leaves through the flexible bag, so that the aroma can be emitted from the basil leaves. Desorption and concentration from the adsorbent were carried out in the same manner as in Example 1, thereby obtaining the aroma liquid (aroma concentrate) of Example 201. The obtained aromatic liquid was subjected to GC-MS/FID analysis in the same manner as in Example 1.

[Comparative Example 201] <Basil, indoor, liquid-air method (previous method)> Using the same basil plant as in Example 201 as animal and plant raw materials, using the device described in Figure 1 of Japanese Patent Application Laid-Open No. 2000-53992, which is the same as Comparative Example 2, and utilizing the air-liquid method (previous method) to trap aroma . A glass container is used as an animal and plant sample storage unit. Store one basil potted seedling as a whole (including the pot) in a glass container, use 2 pumps to introduce humidified air and suck the headspace air under the following conditions, and use a cooling trap (made with dry ice in ethanol Cooled trap) traps aroma components to obtain a condensate (5.3 g). ·Flow rate: air supply (humidification gas) 2.0 L/min, exhaust air (suction) 2.0 L/min. · Capture time: 6 hours After the condensate (5.3 g) was recovered, the entire wall of the cooling trap was washed with 20 mL of diethyl ether, and the entire amount of the obtained liquid was mixed with the condensate. After adding and dissolving 0.8 g of sodium chloride to the obtained mixed solution, liquid separation was performed, and the aqueous layer was extracted twice with 5 mL of ether. The ether layer was dehydrated with Glauber's salt, filtered through filter paper, and concentrated at 43°C under normal pressure to obtain the aroma liquid (aroma concentrate) of Comparative Example 201. The obtained aromatic liquid was subjected to GC-MS/FID analysis in the same manner as in Examples 1 and 201.

[Comparative Example 202] <Basil, indoor, DHS method> The aroma trapping method of Comparative Example 102 was carried out in the same manner as in Example 201 except that the humidified gas generating unit was not used, and non-humidified outside air was supplied. ·Flow rate: air supply (unhumidified outside air) 2.5 L/min, exhaust air (suction) 2.0 L/min. · Capture time: 6 hours ·Every 30 minutes, gently tap the flexible bag from the outside for 1 minute, thereby stimulating the basil leaves through the flexible bag, so that the aroma can be emitted from the basil leaves. Desorption and concentration from the adsorbent were carried out in the same manner as in Examples 1 and 201, thereby obtaining the aroma liquid (aroma concentrate) of Comparative Example 202. The obtained aromatic liquid was subjected to GC-MS/FID analysis in the same manner as in Examples 1 and 201.

[Evaluation] <Sensory Evaluation> For the fragrance liquids (aroma concentrates) of Example 201, Comparative Example 201, and Comparative Example 202, sensory evaluation was performed by 10 well-trained professional sensory inspectors. The fragrance liquid obtained by the air-liquid method (previous method) of Comparative Example 201 has almost no odor. The reason for this is presumed that the aroma of basil was not emitted because the aroma trapping method of Comparative Example 201 could not sufficiently stimulate basil. Comparing the improved method of Japanese Patent Application Laid-Open No. 2000-53992 in Example 201 with the aroma liquid obtained in the DHS method of Comparative Example 202, Example 201 has a fresher and richer impression than Comparative Example 202. The aroma is closer to the aroma of stimulating the real basil leaves.

<Aroma Components> As a result of GC-MS/FID analysis of the aroma liquid (aroma concentrate) of Comparative Example 201, the analysis was difficult because the amount of aroma absorption could not be obtained sufficiently. The abundance ratio (GC-Area%) of the main aroma components detected by the GC-MS/FID analysis results of the aroma liquid (aroma concentrate) of Example 201 and Comparative Example 202 is shown in Table 5 below. "trace" in the table means trace amount.

[table 5]

According to the above-mentioned Table 5, it is clear that linalool (linalool), which has a fresh floral fragrance, is captured in Example 201 at a higher rate than in Comparative Example 202. Also, in Example 201, fresh green (Z)-3-hexenol ((Z)-3-hexenol) and floral nerol (nerol) which were not detected in Comparative Example 202 were captured. ) and geraniol. These are speculated to contribute to the fresh and strong basil-like aroma in the sensory evaluation of Example 201.

<Summary of the evaluation results of basil> Regarding the method of trapping the aroma of basil (sweet basil), it was found that by using the aroma trapping system and method of trapping the aroma of the present invention, it is possible to obtain the aroma that wafts when stimulating real basil. (that is, with a natural feeling) of the fragrance liquid (aroma concentrate). According to the above evaluation results, regarding the method for capturing the aroma of basil, it is considered that the method for capturing the aroma of the present invention carried out in Example 201, that is, the method for capturing the aroma of the improved method of Japanese Patent Laid-Open No. 2000-53992 is relatively efficient.
