PURPOSE:To obtain the deodorant being effective for a methyl mercaptan offensive smell by extracting a leaf, a petal or a fruit of a red flower family, a cedar family, an azalea family and a mandarin orange family by a mixture of a polar solvent, and using an extract as an effective component. CONSTITUTION:A fresh matter or a dry matter of at least one kind of leaf or petal selected from a red flower family plant, a ceder family plant, an azalea family plant and a mandarin orange family plant is extracted by using a mixture of a polar solvent, and a deodorant in which an extract is an effective component is manufactured. It is desirable that the extraction is performed by using a solvent in which water and ethanol are mixed in a volume ratio of 1:(3-6). In the case of groceries, a raw material is dried and pulverized, and by adding a solvent, warm temperature extraction and room temperature extraction are performed. By executing filtration and further adding the solvent to the residue, the warm temperature extraction is executed, a separating filtration is executed, and the filtrate is joined with the filtrate separated previously and enriched. Subsequently, a solid portion and a molten matter are separated, the molten matter is diluted to a prescribed concentration, and a deodorizing liquid is obtained. Also, by drying the deodorizing liquid, a deodorizing solid matter is obtained. In the case of a fresh matter, by adding ethanol to the fresh matter, grinding and crushing it, and performing an extraction processing, a deodorizing solid matter is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for producing a deodorant obtained from plant extract components effective against methyl mercaptan odor.

<Conventional Technology> Today, people's lives are becoming more affluent, and people's interest in the living environment is increasing. Regarding odors, removes bad odors,
There is a growing momentum to make the environment more comfortable. Along with this, it is becoming desirable to take countermeasures against malodor events that were not previously considered as malodor events, and the sources of malodor generation are diversifying. The problem is becoming more and more complex, as there are cases in which a single substance produces a bad odor, and cases in which a large number of trace components are mixed together to produce a bad odor.

Conventionally, methods for removing foul odors include methods of physically adsorbing odor components onto porous surfaces, methods of removing them through adsorption or reaction through chemical bonds, and methods of removing odor components with a stronger aroma than the foul odor components. There are known methods to eliminate bad odors. However, methods using physical adsorption have the disadvantage that the adsorbent itself reaches a saturated state in a short period of time, while methods using chemical adsorption have a high selectivity for malodorous substances and are used in actual malodor events consisting of complex odors. Disadvantages include the fact that it is not suitable for commercial use, that the chemical substances may have an adverse effect on the human body, and that it requires alkaline treatment to deal with acidic odors. Masking methods have the disadvantage that the aromatic components that mask the malodor event do not necessarily suit the taste of the user, or that if the masking agent has a strong odor, it may even cause discomfort.

<Problems to be Solved by the Invention> The present invention was invented to solve the above-mentioned problems.The deodorizing ingredient itself has a weak odor and is a natural product, so it is not safe for the human body. An object of the present invention is to provide a deodorizing agent that can be obtained at a high price and is effective against various odorous substances, and is particularly effective against methyl mercaptan, which emits a pungent sulfur odor and a foul odor similar to rotting onions. It is.

Means for Solving the Problems> That is, the present invention is directed to the use of plants of the family Rusticaceae, specifically evening primrose of the genus Evening primrose, evening primrose, evening primrose,
Plants of the Cedar family, specifically Kouyamaki of the genus Kouyamaki, plants of the Ericaceae family, specifically of the genus Azalea, Hikagege, Paikadge, Astragalus azalea, Akepono azalea, Goyo azalea,
Azalea mitsuba, azalea kobanomitsuba, azalea unzen,
At least one species selected from Kirishima, Yamatsutsuji, Satsukitsutsuji, Ryukyutsutsuji, Omurasaki, Kishitsutsuji, Rutaceae plants, specifically, Citrus genus Daidai, Yuzu, Kishuumikan, Ranshuumikan, Nippon Tachibana, Sudachi, Naramikan, Zapon This is a method for producing a deodorant in which living organisms or dried leaves or petals are extracted using a mixture of polar solvents, and the obtained extract is used as an active ingredient. Preferably, water and ethanol are mixed in 1 part.
Extraction is performed using solvents mixed at a volume ratio of 3 to 6. Preferably, in the process of concentrating the solution, the mixing ratio of water in the solution is increased, and the solution is centrifuged to remove insoluble matter. These steps remove many of the strong odors characteristic of plants. This is a method for producing a deodorant in which an effective deodorizing ingredient is obtained by also removing the solvent.

To obtain the deodorizing substance, when handling it as a dry product, remove moisture from the above raw material in an oven set at 60°C, dry it, and then powder it using a mixer. Add the above solvent at a ratio of approximately 20-1, perform hot extraction at 60°C for 1 hour, perform room temperature extraction for 15 to 24 hours, filter, add the same solvent to the residue and incubate at 60°C for 1 hour. After hot extraction for several hours, it is separated and filtered.
The filtrate is combined with the previously separated filtrate and concentrated using a rotary evaporator, etc. After the concentrated liquid is centrifuged to separate solids and dissolved matter, only the dissolved matter is placed in a volumetric flask and water is added. A deodorizing liquid can be obtained by diluting it to a certain concentration. Further, this deodorizing liquid is dried under reduced pressure to obtain a deodorizing solid, which is used for actual deodorizing.

When handling as a living organism, add 20-1 ethanol to the living organism equivalent to 1 g of dry matter, grind with a homogenizer, and perform the same extraction process to obtain a deodorized solid.

<Effect> This extracted solid is highly safe and easily obtained from plants, and is effective in removing various bad odors, especially against methyl mercaptan, which gives off a pungent sulfur odor and rotting onion odor. The effect is excellent. Furthermore, since the solid substance itself has very little odor, it does not cause unpleasant sensations like conventional masking agents, and the raw materials are inexpensive.

The mechanism of odor action is a complex combination of neutralization, decomposition, redox, complex formation, and clathration with flavonoids, polyphenols, amino acids, chlorophyll, etc. in the multi-component hybrid system of plant extract components. It is estimated that The present invention will be explained in more detail with reference to Examples below.

Example 1 5g powder of dried evening primrose flowers, water; ethanol = 1:
4 and 100 ml of a mixed solvent with a volume ratio of 1.5 to 1.4 was placed in an Erlenmeyer flask, and after a hot water bath at 60° C. for 1 hour, extraction was performed at room temperature for 15 hours. After suction filtration and separating the extract, the same solvent of 1001 was added to the residue again and the mixture was heated at 60°C for 1 hour.
Re-extraction was performed.

After suction filtration, the filtrate was combined with the previous extract, subjected to -a condensation, and then centrifuged to separate the solid content. The liquid portion was diluted with water to 100 ml in a volumetric flask to obtain a deodorizing liquid. Dry 5 ml of this under reduced pressure to make a solid deodorant of about 60 ml.
-g was obtained.

Example 2 7 g of dried leaf powder of Kouyamaki and water: ethanol-2
A mixed solvent 1501, which is a volume ratio of Nia, was placed in an Erlenmeyer flask, and the same operation as in Example 1 was performed to obtain 100 ml of deodorizing liquid. Of this, 5 liters were dried under reduced pressure to obtain about 751 g of solid deodorant.

Example 3 7 g of dried flowers of Satsuki azalea and water: Ethanol = 2:
The same operation as in Example 1 was performed using 150 ml of a mixed solvent having a volume ratio of 1,001 to 1,001 to obtain a deodorizing liquid of 1,001. Of these, 51 pieces were dried under reduced pressure to obtain about 150 g of solid deodorizing seeds.

Example 4 Using 7 g of dried summer mandarin leaves and 150 ml of a mixed solvent having a volume ratio of water:ethanol=1:5, the same operation as in Example 1 was carried out to obtain 100 ml of deodorizing liquid. Of these, 5-1 was dried under reduced pressure, and approximately 10 (1+g) of solid deodorant was obtained.
I got it.

Test Example The deodorizing effect of methyl mercaptan was measured for the deodorant liquids obtained in Examples 1 to 4.

-Test Method A solid deodorant corresponding to Deodorant Liquid 5-1 and about 1600 μg of methyl mercaptan gas were placed in a 16f)+1 capacity glass bottle and sealed. A sample without solid deodorant was also prepared as a blank. This was stored in a constant temperature bath set at 20°C, and after 2.5 hours of treatment, the amount of gas remaining in each bottle was measured using a gas chromatograph. a) and the gas loss in the blank bottle, i.e. the amount adsorbed on the glassware wall (b)
The amount of gas deodorized by the deodorant itself was calculated from a-b.

From this calculation result, the amount of gas adsorption of the deodorant per 1 g of dry matter was determined and shown in FIG. For comparison, the gas adsorption amounts of other plant components obtained using the same extraction method are also listed.

The adsorbed gas amount of Camellia family plants, which are said to be highly effective as deodorizers using plant ingredients, and other plants tested using the same extraction method was 430 μg/1g of dry matter.
In contrast, all of the plants used in the present invention exceeded 450 μg, which indicates that they are even better.

<Effects of the Invention> As described above, the deodorant obtained by the present invention has raw materials that are inexpensive and easy to obtain, a manufacturing method that is simple, and is highly effective. Since the deodorant itself has an extremely low odor, it can be effective in a variety of fields without causing discomfort. In addition, although there have been inventions related to deodorants using plant ingredients, for example, those using extracts from plants of the Camellia family, it can be seen from the figure that the effects are superior to those, and the present invention is extremely effective. It can be said that this is a highly effective and practical invention.
