Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is directed to the unpleasant odor of food materials, the odor of ordinary households,
The present invention relates to a deodorant characterized by being effective and safe against odors generated in industry and other odors, and a method for producing the same.

[Conventional technology]

In recent years, as the level of food, clothing, and shelter has risen rapidly, awareness of the living environment has increased. Of the complaints about pollution, odor complaints are the second largest after noise complaints, and their resolution is an urgent task. Generally, deodorizing methods are roughly classified into (1) sensory deodorizing method, (2) chemical deodorizing method, and (3)
There are physical deodorant method, (4) biological deodorant method, and others.
As the sensory deodorizing method of (1), there are a method utilizing neutralization of odor and a method utilizing masking effect. (2)
The chemical deodorization method of is, neutralization reaction, redox, addition,
There are things that use chemical reactions such as polymerization and condensation,
Examples of the physical deodorizing method (3) include an adsorption reaction with activated carbon and the like. Examples of the biological deodorizing method (4) include a method utilizing the action of microorganisms such as activated sludge and a method using oxygen. However, the sensory deodorizing method of (1) has a drawback that, for example, it is not a fundamental deodorant and the odor of the masking agent itself becomes a problem. The chemical deodorizing method (2) has many problems in terms of odor selectivity and difficulty in dealing with various odors, and when used in foods, in terms of safety of its components. Even in the physical deodorization method of (3), there are problems with the odor selectivity and the equipment,
The biological deodorant method (4) has safety and other problems.

[Problems to be Solved by the Invention]

The present invention solves the problems of the above deodorant method, and is a highly safe deodorant that can be used in a wide range of foods, general households and industries, and a method for producing the same. .

[Means for solving the problem]

The present inventors have previously found that an extract having an effect of deodorizing is contained in an extract obtained by distillation or dry distillation of leguminous Clara plants, such as Enju, etc.
63-189340). The inventors of the present invention continued to study diligently and took out the rutin contained in the buds and the like of Enju,
To 1 part of rutin (weight, the same applies hereinafter), at least one solvent having a boiling point of 100 ° C or higher, such as glycerin or propylene glycol, is added and mixed at a ratio of 1 part or more, and vacuum distillation is performed to obtain 170 at a vacuum degree of 20 mmHg. We succeeded in obtaining a slightly fragrant pale yellow active ingredient with a boiling range of ~ 200 ℃.

The temperature in this vacuum distillation cannot be uniquely determined in relation to the degree of vacuum.

The deodorant component thus obtained may be used as it is or may be formulated into an arbitrary form depending on the purpose of deodorization. For example, household odors such as trays and garbage,
For the removal of odors from factories, refuse treatment plants, sewage treatment plants, livestock houses, etc., a solution of ethanol or other lower alcohol solvent, etc., dissolved in water or a mixture thereof,
It can be sprayed as it is or sprayed and used. Glycerin and other polyhydric alcohol solvents, ethanol and other lower alcohol solvents, a solution dissolved in water or a mixture thereof, or this solution is, for example, spray-dried and added as a powder product to foods, pharmaceuticals, etc. Can be used.

Example 1 100 g of rutin (quercetin-3-rutinoside)
By mixing 150 g of glycerin and vacuum distillation, the degree of vacuum is 20 mm.
About 110 g of a distillate with a boiling point range of 170 to 200 ℃ in Hg and a deodorant effect of a slightly fragrant pale yellow color was obtained. To 50 parts of this fraction, 25 parts of glycerin and 25 parts of ethanol were added to obtain a liquid deodorant.

Next, the effect of the deodorant of the present invention will be proved with experimental examples.

Experimental Example 1 With respect to the liquid deodorant obtained in Example, the deodorizing effect on trimethylamine and dimethyl sulfide was examined by using gas chromatography.

3 g of a 500 ppm trimethylamine aqueous solution or 3 g of a 600 ppm dimethyl sulfide aqueous solution and 5 g of the deodorant obtained in Example 1
The mixture was placed in a 100 ml Erlenmeyer flask, well stirred, and then sealed. 20
After 1 minute, 1 ml of the gas in the headspace was injected into gas chromatography, and the residual ratio of the malodorous component was determined from the peak area of the obtained gas chromatogram. The results are shown in Table 1.

Experimental Example 2 Example 1 was applied to 10 parts of garlic powder (manufactured by Sanei Chemical Industry Co., Ltd.) suspended in demineralized water to 0.1%.
0.1 part of the deodorant obtained in 1. was added. As a control, only a solvent in which 75 parts of glycerin and 25 parts of ethanol were mixed was used as a control. After 20 minutes, the deodorizing effect is shown below 4
Sensory evaluation was performed by 10 panelists using a graded evaluation method. The results are shown in Table 2 by the number of panelists who evaluated each stage.

Evaluation criteria −: No effect ＋: Some effect ： Effective ： High effect Experimental Example 3 Plasma prepared from bovine blood was made into powder by spray drying. Deionized water was added to this powder to make a 1% suspension 10
To 0 part, 0.1 part of the deodorant obtained in Example 1 was added.
Glycerin 50 parts, ethanol 25 parts, demineralized water 25 as a control
Only a mixed solvent was added to serve as a control. After 20 minutes, the deodorizing effect was sensory-evaluated by 10 panelists using the same four-level evaluation method as in Experimental Example 2. The result is the third
Shown in the table.

[Effects of the Invention] As is clear from the above Examples and Experimental Examples, the present invention relates to a highly effective deodorant using rutin as a raw material and a method for producing the same. The method of use is not limited to the prevention of offensive odors of foods, but can be applied in various fields in a wide range such as prevention of offensive odors in general households and industries.
