Description

  The present invention relates to a fragrance composition, and more specifically, consists of an aqueous fraction of a distillate obtained by heating a plant under reduced pressure, and is used as it is as a fragrance / deodorant or antibacterial agent without concentration or the like It relates to a possible fragrance composition.

  Conventionally, spray type using spray or ultrasonic vibrator to deodorize or impart odor to living space such as living rooms, toilets, entrances, etc. and solid surfaces such as clothing, sofas, curtains and other textiles Or volatile or deodorant of wicking volatilization type is used. Such fragrances and deodorants are based on water, in which oily fragrances and deodorant components such as plant essential oils are solubilized with water-soluble solvents such as surfactants and glycol ethers.

  However, since the surfactants used for solubilizing fragrances and the like are non-volatile components, they adhere to the fiber product, causing problems such as stickiness on the surface and damage to the texture, and accumulation of non-volatile components to the human body. There was a problem of adverse effects. In addition, in the case of the volatile odor and deodorant, the surfactant accumulates on the wick and the volatile material, and there is a case where uniform volatilization cannot be performed. Similarly, the spray type using a mesh-type ultrasonic vibrator has a problem that the surfactant accumulates in the mesh and becomes clogged, resulting in a decrease in spray performance.

  In addition, attempts have been made to use aqueous fractions obtained by steam distillation as cosmetics and fragrances as floral water, etc. However, since it was necessary to add a large amount of steam during steam distillation, the concentration of fragrance components, etc. Only a very low aqueous fraction was obtained. For this reason, in order to use as a fragrance | flavor or a deodorant, it became necessary to concentrate further, and since the fragrance | flavor component etc. volatilized in the concentration process or the cost became high, it was hardly brought to practical use. .

  In addition, citrus essential oil and floral water obtained by vacuum distillation using a citrus juice vibration sieve residue of citrus fruits such as eggplant as a raw material are described (Patent Document 1), but since these are heated in a warm bath, It was necessary to add more than the same amount of water to impart fluidity, and the extracted floral water still had very low concentrations of aroma components and the like.

  Accordingly, an object of the present invention is to provide an aqueous fragrance composition that does not contain a non-volatile component such as a surfactant and contains a sufficient concentration of fragrance component and the like and can be used as it is as a fragrance.

  As a result of diligent research, the inventors of the present invention obtained a water-based fraction having a high concentration of fragrance components and the like that can be directly used as a fragrance by heating and distilling the plant using microwaves under reduced pressure. In addition, it was found that this aqueous fraction also has a deodorizing action, an antibacterial action and the like, and the present invention has been completed.

  That is, the present invention is an aroma composition comprising an aqueous fraction of a distillate obtained by heating a plant by irradiating microwaves under reduced pressure.

  Moreover, this invention is a fragrance | flavor, a deodorizing agent, or an antibacterial agent which uses the said fragrance composition as an active ingredient.

  Furthermore, the present invention is the above-described method for producing an aroma composition, characterized in that a plant is heated by irradiation with microwaves under reduced pressure, and an aqueous fraction is collected from the obtained distillate.

  Since the fragrance composition of the present invention contains a fragrance component and the like at a high concentration, it can be used as it is as a fragrance without being concentrated. In addition, since it is water-based and does not contain non-volatile components such as surfactants, even if it is sprayed on textiles, it can impart fragrance without sticking to the surface or impairing the texture. Even if it is done, there is no fear of health damage due to accumulation of non-volatile components, and safety is high. Furthermore, even if the suction vaporization type or mesh type ultrasonic atomizer is used, clogging does not occur in the suction core or mesh, so that the volatilization / spraying performance can be stably maintained. Furthermore, this fragrance composition has an excellent deodorizing action, antibacterial action, pest repellent action, and the like.

It is the figure which showed typically the structure of the microwave vacuum distillation apparatus used with this invention method. It is a figure which shows the test device used in Example 15. FIG. It is a figure which shows the ultrasonic atomizer used in Example 16. FIG. It is a figure which shows the sucking volatilization type deodorizing and aroma device used in Example 17.

  The fragrance composition of the present invention comprises an aqueous fraction of a distillate obtained by performing distillation by irradiating a plant with microwaves under reduced pressure.

  The raw material plant is not particularly limited, and examples thereof include trees, fruit trees, vegetables, and flowers. Further, the parts of these plants are not particularly limited, and examples thereof include leaves, fruits, fruit skins, flowers, seeds, and roots.

  The above-mentioned tree is preferably a conifer, for example, hinoki, hinoki cypress, bay hiba, sawara, lawson hinoki, chabo hiba, peacock hiba, ogon chabo hiba, water lily hiba, itiba, ogon hiyoku hiba, shinobhiba, ogon shinobu hiba, cypress family Trees of the genus Cypresses; Trees of the genus Cypress family of cypresses such as Japanese cypress, Nizuko; Trees of the genus Asunaro family such as Hiba, Asunaro, Hinoki Asunaro, Hosoba Asunaro; Cypressaceae such as Hijaxin, Nezumisashi, Emphibibicus, Okinawa Trees of the genus: Sugi, Japanese cedar, Enkousugi, Joresugi, Ogonsugi, Japanese cedar, Japanese cedar, and other cypresses of the cypress family; Todomatsu, Fir, Virgin fir, Shirabiso, Oshirabiso, Sirabe, Balsamfer, Mi Trees of the genus Firaceae, such as Minemimi, White Fur, Amabilis, California Red Fur, Grand Fur, Noble Fur, etc .; Trees of the genus Cedar, such as Cedar, Cedar genus, Spruce, Spruce, etc. Trees; Pinus pine genus trees such as Japanese red pine, Japanese red pine, strobe pine, and high pine; Trees of pine genus Larch genus such as larch; Trees of genus Pinaceae genus such as pine; Trees of genus Koyamaki such as Kouyamaki; Examples of the tree of the genus Kaya. These coniferous leaves are preferably used, and thinned wood or branches and leaves obtained by pruning may be used as they are, but are preferably used after being pulverized and crushed by a pulverizer or a crusher.

  Examples of the fruit trees include apples, grapes, mandarin oranges, peaches, kiwi fruits, grapefruits, etc. In addition to the fruits and skins, parts such as leaves, roots and stems can also be used. Residue (squeezed residue) including fruit peels can also be used.

  Examples of the vegetables include cabbage komatsuna, lettuce, green pepper, Chinese cabbage, perilla and strawberry. Examples of the flowers include rush, jasmine, gardenia, rose, quince, mandarin flower, lavender and the like.

  The plant can be used even if it has been damaged by pests. In addition, by using the juice residue of fruit trees that have been conventionally discarded and the leaves of conifers that have been rarely used as raw materials, these resources can be made useful and advantageous in terms of economy.

  A microwave is used as a heat source for obtaining an aqueous fragrance composition from the plant. By irradiating the plant with microwaves, it becomes possible to directly heat the water molecules originally contained in the raw material and distill only with the evaporated water, and to reduce the concentration of aromatic components etc. in the aqueous fraction of the distillate. Can be increased. Water may be added as necessary, and even in this case, since the amount of water added can be greatly reduced compared to the conventional case, an aqueous fraction having a high concentration of aroma components and the like can be obtained. Moreover, since the water contained in the plant is uniformly and efficiently heated by using the microwave, distillation can be performed in a short time, and the workability and cost are excellent.

  In order to carry out this microwave vacuum distillation method, a microwave vacuum distillation apparatus is required. The outline of this apparatus is shown in FIG. In the figure, 1 is a microwave vacuum distillation apparatus, 2 is a distillation tank, 3 is a microwave heating apparatus, 4 is a stirring splash, 5 is an airflow inflow pipe, 6 is a distillate outflow pipe, 7 is a cooling apparatus, and 8 is heating. Control device, 9 is a decompression pump, 10 is a pressure regulating valve, 11 is a pressure control device, 12 is a distillation object, and 13 is a distillate.

  In this apparatus 1, a raw material plant to be a distillation object 12 is placed in a distillation tank 2, and microwaves are radiated from a microwave heating apparatus 3 provided on the upper surface of the distillation tank 2 while stirring with a stirring splash 4. And heat the raw material. The distillation tank 2 communicates with the air flow inlet 5 and the distillate outflow pipe 6. The airflow inlet pipe 5 introduces an inert gas such as air or nitrogen gas into the reaction tank 2, and this airflow is introduced from the lower part of the reaction tank 2. The distillate outflow pipe 6 leads the distillate from the raw material to the outside from the upper part of the reaction tank 2.

  The temperature and pressure of the inside of the reaction tank 2 are measured by a temperature sensor and a pressure sensor (both not shown) attached to the reaction tank 2, and a heating control device 8, a pressure control device 11, and a pressure adjusting valve are measured. 10 are adjusted respectively.

  The gaseous distillate flowing out from the distillation tank 2 through the distillate outflow pipe 6 is replaced with a liquid by the cooling device 7 and obtained as a distillate 13. The distillate 13 includes an oily fraction 13a and an aqueous fraction 13b. Of these, the aqueous fraction 13b is the aroma composition of the present invention.

  In the method of the present invention, the pressure in the distillation tank 2 may be set to 10 to 95 kilopascals, preferably 20 to 80 kilopascals, more preferably about 30 to 60 kilopascals. 40 ° C to 100 ° C. When the pressure is 10 kPa or less, the increase in the vapor pressure of the volatile components in the plant is suppressed, and the vacuum distillation component due to the boiling point of each component is the main component from the steam distillation component, and it flows out in order from the lowest boiling point. Therefore, extraction of a plant component having a boiling point higher than that of water is not preferable in that it is not efficiently performed. Moreover, since the temperature of a sample becomes high at 95 kilopascals or more, it is not preferable in that the energy loss is large and the oxidation of the sample is promoted. The distillation time may be about 0.2 to 8 hours, preferably about 0.4 to 6 hours. If it is 0.2 hours or less, a lot of unextracted components remain in the plant, and if it is 8 hours or more, the sample becomes nearly dry, which is not preferable in that the extraction efficiency decreases.

  Furthermore, the gas introduced into the distillation tank 2 may be air, but an inert gas such as nitrogen gas, helium gas, or argon gas is preferable, and the flow rate per minute is the distillation tank 2. It may be about 0.001 to 0.1 times the capacity.

  Since the fragrance composition of the present invention thus obtained contains a fragrance component and the like at a high concentration, a step such as further concentration is unnecessary, and it can be used as a fragrance as it is. And since this fragrance composition is an aqueous composition that does not contain a non-volatile component such as a surfactant, even if it is applied to a textile product, it does not become sticky or lose its texture, and is sprayed or volatilized in the space. However, it is highly safe without fear of health damage due to accumulation of non-volatile components. Furthermore, even if it is a suction volatilization type or a mesh type ultrasonic sprayer, the volatilization / spraying performance can be maintained without clogging the suction core or mesh.

  Moreover, since the fragrance composition of this invention has the outstanding fragrance and is a highly safe thing, it can add to food-drinks as a fragrance | flavor and can improve flavor. Furthermore, since it has a deodorizing action, an antibacterial action, and an attracting or repelling action against pests such as mites and cockroaches, it can be used as an aroma / deodorant, an antibacterial agent, a pest attractant, a repellent and the like.

  In preparing a fragrance / deodorant, an antibacterial agent, a pest attractant or a pest repellent, other perfume ingredients may be blended for the purpose of adjusting the scent. Examples of other perfume ingredients include hydrocarbon perfumes such as pinene and limonene, alcohol perfumes such as linalool, geraniol, citronellol, menthol, borneol, benzyl alcohol, anis alcohol, β-phenethyl alcohol, anethole, eugenol and the like.

It is done.

  Among these, it is preferable to use a fragrance component that satisfies the condition that the water / octanol partition coefficient is 1 to 4.5. As perfume ingredients satisfying a water / octanol partition coefficient of 1 to 4.5, anis alcohol, anisaldehyde, acetophenone, isoeugenol, isoamyl acetate, isomethyl ionone, ethyl vanillin, eugenol, octanol, octanal, osimene, camphor, geraniol , Geranyl acetate, Cymene, Citronellol, Cineol, Dihydromyrsenol, Cinamic alcohol, Cinamic aldehyde, Terpineol, Decalactone, Tetrahydrogeraniol, Tetrahydrolinalol, Nerol, Pinene, Butyl acetate, Phenethyl alcohol, Hexanal, Hexanol, Hexenol, Pregon , Heliotropin, benzyl acetate, benzyl alcohol, benzaldehyde, ben Examples include, but are not limited to, zilfomate, borneol, bornyl acetate, myrsenol, myrcene, methyl salicylate, menthol, menthone, yonon, linalyl acetate, linalool, limonene, and the like. Moreover, these 1 type (s) or 2 or more types can also be mixed and used. Further, if necessary, a surfactant, a hydrotrope agent and the like can be used as long as the effects of the present invention are not impaired.

  In blending other fragrance ingredients, the fragrance ingredients may be mixed and stirred in the fragrance composition, but the fragrance ingredients are pre-supported on a solid support and immersed in the fragrance composition. The fragrance component supported on the solid support may be blended so that it is gradually released into the fragrance composition. As the solid support, any of pellets such as polypropylene, polyethylene and EVA, organic carriers such as cellulose moldings, and inorganic carriers such as silica gel, zeolite, florisil and fluorite can be used. From the viewpoint of properties and handling, organic carriers such as polypropylene, polyethylene and EVA are suitable.
